Rope is easy to take for granted. It seems obvious and straightforward. But of course, it had to be invented. Early humans discovered that by twisting fibers around each other, the resulting structure would be something durable and strong. Without rope, all kinds of things aren't possible, from lifting objects into the air to whaling or modern bridges. So how was it developed and what were the big breakthroughs in its history? On this episode, we speak with Tim Queeney, the author of the recent book Rope: How a Bundle of Twisted Fibers Became the Backbone of Civilization. He walks us through the history of the technology, and its ongoing evolution, including how it might one day allow to build an elevator into outer space.

There's been a massive selloff in the bond market and rates are rising all around the world. Japan, Korea, the UK... You name it. Gita Gopinath, Harvard economics professor and the former first deputy managing director of the IMF, has long warned that bond markets are "in a fragile place." She sees a confluence of demographics, high levels of public debt, and the intense capital needs of the AI boom creating inflationary pressure all around the world. Today we speak with Gopinath about the seeming disconnect between stocks and bonds and why investors may be wrong to assume that governments will have their back the next time there's a major shock.

We love talking about money. And of course, we love talking about the dollar, in all its varieties — from bank deposits to eurodollars to stablecoins. But what fundamentally is a dollar and who actually controls it? To understand these questions, you need to understand how the dollar was born. Journalist (and current Ph.D. candidate in financial history) Brendan Greeley argues not only that the dollar is older than you might suspect, but that the dollar long precedes the United States itself. In fact, the word is derived from German, referring to a Spanish currency made from silver found in Mexico. In this episode, we discuss Brendan's new book, The Almighty Dollar: 500 Years of the World's Most Powerful Money. He explains not only the dollar's surprising history, but also what actually backs the US dollar and gives it purchasing power.

As our listeners know, restaurants are great microcosms for macro-economic trends. They sit at the intersection of everything from consumer confidence to commodity costs to the labor market. So on our recent visit to London, we wanted to learn about the business of pubs. According to the British Beer and Pub Association, approximately two pubs a day have closed in England during the first quarter of 2026. Could pubs tell us something about larger trends in the British economy? And when it comes to the day-to-day operations of the business: How is a pub different from a regular bar? And how are publicans — pub managers — dealing with the era of the £10 pint? Today's episode is a special two-parter, devoted to the business of pubs. We talk to Oisin Rogers and Ashley Palmer-Watts, co-founders of the Devonshire, a famed London pub. The first part is with Rogers, who is the publican, and we discuss the difference between a good and bad pub, why he hates the word 'gastropub,' and how the indoor smoking ban changed the meaning of pubs for the average Londoner. Second up is a segment from our London live show with the Devonshire chef Palmer-Watts, who tells us about the complicated confluence of factors — from temperature to the right mix of gases — that lead to a perfect pint of Guinness, why higher ingredient costs (whether it's beef or scallops) don't always correlate to higher menu prices, and making a Victorian-era meat fruit for Apple's Jony Ive.

Not many people think of designing buildings as an exercise in economics, but the entire process is defined by constraints around resources (both physical and financial), and an iconic building can also have a huge impact on the wealth and development of the area around it. So how do you encourage private developers to consider the public good when designing new projects? And how are some countries able to encourage more landmark building projects than others? In this episode, we speak with Norman Foster, renowned architect and founder of Foster + Partners. We talk to him about how constraints impact his own design process, how building budgets actually work, what makes a building successful in the long run, why China keeps completing mega-project after mega-project, and why places like the UK and the US are now struggling to keep up.

A short seller is a gumshoe who roots out a particular story about a specific company and brings it to light. And Fahmi Quadir, the founder and CIO of Safkhet Capital, has been labeled "The Assassin" for being one of the most famous, successfully betting against companies like Wirecard and Valeant. In today's conversation with Quadir, recorded at our live show in London at Wilton's Music Hall, she dishes on what life is like for a short seller and why betting against stocks has been getting harder even during what she calls a "golden age of fraud." She also reveals that she's going long for the first time ever by investing strategically in one of the world's best-performing markets.

Size is the name of the game for the AI chipmaker Cerebras: Their chips are truly massive, about the size of a dinner plate. According to Andrew Feldman, CEO and founder of Cerebras, that is about 58 times larger than the average chip. That sheer size enables blazing fast inference for AI queries. Feldman joins us on the week of his company's IPO to talk about his core product and how it fits into the AI boom. We discuss the history of the GPU, competition between open-and closed-source models, the company's relationship with with TSMC, and more.

It is hard to have a markets conversation that isn't out of date within a minute or two. But we think this one, with Ozan Tarman and Aditya Singhal of Deutsche Bank, is basically evergreen. This conversation, recorded at our live show at Wilton's Music Hall in London, is all about fundamentals: How Tarman, DB's vice chair of global macro, and Singhal, the firm’s head of EM trading across rates, FX and Credit, make sense of conflicting headlines, whether the rally in tech stocks is to be believed, the tug of war between fast money and central bankers, and how traders are evaluating the difference between the AI models coming out of the US and China.

Whether it's the price of a barrel of Brent crude or a pound of beef, it's clear prices are skyrocketing for all kinds of goods and commodities. Price shocks and shortages are, if anything, the way consumers understand the economy right now — at the grocery store or at the gas pump. Certainly, current (and future) shocks can be explained by the closure of the Strait of Hormuz. But the environment is weirder than just across the board price increases: The price of corn has barely moved, for instance, while fertilizer just keeps going up. We have not one but two perfect guests to talk to us today, our favorite commodity specialists: Bloomberg Opinion columnist Javier Blas and Lorcan Roche Kelly, the business editor at Irish Farmers Journal. Today's episode — which was recorded on stage at Wilton's Music Hall in London as part of our first ever show outside the US — covers how the world's farmers feel about US trade policy, why today's energy shock is so different from 2022's, the true impact of the UAE leaving OPEC, and why it's going to get harder to buy hard cheese in the near future.

The internet is made for shopping. For years, the main inputs for e-commerce transactions involved targeted ads, algorithmic recommendations, SEO, and lots of mindless scrolling. But agentic commerce might represent a sea change for e-commerce: With the rise of AI agents doing shopping on behalf of consumers, how are retailers going to adapt? John Collison, co-founder of the financial services and payment processing company Stripe, has first-hand experience with all the ways e-commerce has changed in the last decade, and he thinks agentic commerce is going to completely transform the online shopping experience. On this episode, we speak to Collison about how AI has already changed the way consumers make purchasing decisions, why keyword search is a "ridiculous" way to find things to buy, what it means when brands will have to appeal to AI agents as opposed to human buyers, and if AI agents can truly mimic human taste.

Making a long career as a bear at a sell-side institution is tough. Generally financial markets have done quite well which means forecasting doom and gloom is, usually, only tenable for so long. Which is why we wanted to talk to one of the most successful bears out there. Société Générale has let Albert Edwards out of the bear cage for today's episode. Edwards knows his reputation as a bear is well deserved: He believes, among other things, double-digit inflation is in the offing. We also talk about the attention span of readers on the buy-side, what success looks like for a bear, and how a bear avoids getting fired.

Last year, when we talked to Martin Wolf, the global order seemed like it was being upended after President Trump unveiled his sweeping tariffs against nearly every US trading partner. A lot has happened since then. In fact, April 2025 seems almost quaint when compared to 2026 so far, from the Supreme Court's tariff ruling to the US-Israel war with Iran. The war's effect on the world's economy is at once stunning and utterly strange: even as the prices of major commodities — oil chief among them — rise, the markets seem unaffected, closing at record levels in recent weeks. Today we speak with Wolf, the chief economics commentator for the Financial Times, about all this chaos and why, so far, it seems disconnected from the logic of the market. There is, he says, a great deal of ruin in the world economy, but growth remains a constant fact of life. Why is that? There's no straightforward answer, but to begin understanding how we got here, Wolf takes us to the early 20th century and paints us a picture of the world after the two World Wars. We also talk about the "terrifying" power that the US wields over the globe, how a fragmented Europe is navigating anxious relationships with both the US and China, the Faustian bargain AI represents, and much more.

In 2006, then-Senator Ted Stevens coined an infamous term for how to understand the internet: It's a "series of tubes." The funny thing is, that's a fairly accurate description. Underneath the world's oceans, miles and miles of fiber optic-cables send packets of information from one location to the next, serving as the backbone of the internet as know it. This infrastructure is delicate, too: Memorably, a 2022 volcanic eruption cut off the island of Tonga from web access for an extended period of time. Journalist Samanth Subramanian is the author of The Web Beneath the Waves: The Fragile Cables That Connect Our World, a book that explains, in detail, that the internet is not, and has never been, truly weightless or wireless. In fact, the system in place right now is pretty old school and resembles the telegraph cable network of yore. We talk to Subramanian about the strange contradictions of the undersea cable system, how much basic marine geography — like the Strait of Hormuz or the Suez Canal — informs where cables are laid, and how hard it is protect this vulnerable and vital infrastructure.

Ever since Covid, central banks around the world have had the same problem. They have tools that are designed to modulate demand, but so many challenges have involved the supply side of the economy. Whether we're talking about supply chain disruptions, the war in Ukraine, and now the war in Iran, these are all issues for which monetary policy is of limited value. Of course, the temptation is to "look through" these events, recognizing the fact that these disruptions don't say much about the actual underlying state of the economy. But when we get one shock after another, it gets harder and harder to keep using words like "transitory." On this episode we speak with Megan Greene, an external member of the Monetary Policy Committee at the Bank of England. We talk about the compounding effects of all these shocks (including the trade war and Brexit), how she's thinking about the first- and second-order effects of each, and why for now, despite the underlying weakness of the UK economy, she remains squarely focused on the risks of higher inflation.

Today's guest Mariana Mazzucato is one of our most requested. Mazzucato, a professor of economics at University College London and the founding director of its Institute for Innovation and Public Purpose, specializes in the political economy of technological development and public sector investment. In our conversation, recorded in Madrid while at the Bloomberg CityLab conference, she explains her concept of the "mission economy," her definition of state capacity, how to prevent top talent from fleeing to the private sector, and whether consultants or governments should be blamed for inefficiencies and civic failures. It's a wide-ranging interview, one that covers everything from the initial public financing of Silicon Valley algorithms to the history of moonshots.

The residents of Allentown are still sore about that Billy Joel song. While it's true the Pennsylvania city became synonymous with deindustrialization after the US steel industry began its decline in the 1970s, Allentown should be known for more: In the 1950s, for instance, some of the first mass-produced transistors were made in the city, which were the precursor of today's semiconductors. The city is also a unique logistics and e-commerce hub — it's a day's drive from nearly 40 percent of the US population. Mayor Matthew Tuerk, who has held office since 2022, has made reindustrialization a focus of his mayorship. In today's episode, recorded in Madrid at the Bloomberg CityLab conference, we speak to Mayor Tuerk about the city's grand strategy for building back and sustaining its manufacturing base, implementing industrial policy on a local level, how rezoning has changed in the last decade, the political puzzle of data centers, recruiting companies to come to Allentown, de-risking the American supply chain, and our favorite new category of industry — weight-gaining industries — which Allentown specializes in.

Since Mayor Brandon Scott took office in 2020, he's fixated on a very visible problem in Baltimore: the tens of thousands of vacant homes that dot the city. It's hard to build new houses when there are so many that sit empty and unused. And the process of tracking down owners, convincing them to sell their vacant properties, and then converting those homes into usable housing supply is a tall task. In the last few years, the number of vacant homes in Baltimore has dropped from 16,000 to just over 11,800. On this episode — recorded in Madrid while we attended the Bloomberg CityLab conference — we speak to Mayor Scott about deindustrialization, redlining, and gun violence's historical effects on the current housing crisis, how his government identifies, block-by-block, redevelopment opportunities and matches projects with publicly-minded developers, and why Baltimore natives aren't huge fans of The Wire.

Two years ago, Citadel's Ken Griffin paid almost $45 million for a stegosaurus skeleton, making it the most expensive fossil ever sold at auction. So why are dinosaur bones joining the collections of millionaires instead of museums? How does the private market for fossils actually work? And how similar is it to the market for art and other antiquities? In this episode, we speak with Salomon Aaron, a director at London-based gallery David Aaron, where he is the gallery's in-house broker for dinosaur fossils. We talk about how fossils are found and priced, what it's like to work alongside dinosaur hunters, how his gallery identifies potential buyers, and why Joe thinks something about the birds-to-dinosaurs evolutionary pipeline is off.

The closure of the Strait of Hormuz has highlighted the potential for long-running theoretical chokepoints to turn into reality, with dramatic results for both geopolitics and the global economy. But the hypothetical scenario that policymakers have arguably been losing the most sleep over for decades is the prospect of a major conflict between China and Taiwan. So how likely is it, and what would such a conflict actually look like? On this episode, we speak with Eyck Freymann, author of the new book, Defending Taiwan: A Strategy to Prevent War With China, and a fellow at the Hoover Institution at Stanford University. We discuss Xi Jinping's strategy, whether Taiwan's "silicon shield" of semiconductor manufacturing can last forever, the state of Taiwan's domestic politics, and what the US can do to deter such a conflict.

The last few decades have been marked by a number of megatrends in finance including the extraordinary growth of asset managers, the rising importance of technology, and the ascent of private markets. BlackRock, the world's biggest asset manager, is emblematic of all these developments. On this episode, we talk to BlackRock COO Rob Goldstein about the company's early technological history, the development of its famous risk management technology Aladdin, and how BlackRock is navigating being both a user and major provider of AI. We discuss his view of the 'SaaSpocalypse,' how BlackRock is thinking about token consumption and compute constraint, as well as the future of private markets.

The private credit market has grown enormously fast in recent years — so much so that by some estimates it's now bigger than the market for junk-rated corporate bonds. So what's driven all that growth? What impact has private credit had on other types of corporate debt? And why are there so many concerns around the space right now? In this episode, we speak with John Sheehan and Craig Manchuck, two veteran portfolio managers for the strategic income fund at Osterweis Capital Management. We talk about the history of private credit before and after 2008, private credit's links with private equity and insurance, the prospect of higher defaults, and what to watch for right now.

We live in an era of charts that are going up and to the right. This image obviously describes the stock market, particularly any company whose business is adjacent to artificial intelligence. But beyond stocks, another sort of chart we keep seeing is of AI capabilities also going up and to the right. The most famous and viral of these comes from an organization called METR, which stands for Model Evaluation and Threat Research. The organization is focused on understanding the degree to which AI models can engage in autonomous, complex tasks. METR see this is as a particularly important benchmark, given the risk that AI could one day be engaged in recursive self improvement, taking humans out of the loop. But how do you really gauge a model's ability to do complex problems. And what is being measured for exactly? On this episode, we speak with METR's President Chris Painter as well as Joel Becker, a member of the technical staff who works on evaluation methods for the organization. We discuss both the mechanics and the philosophy of METR's work, and what it means when we see a a chart showing that Clause Opus 4.6 can do a task that would take a human nearly 12 hours.

We're living in an extraordinary moment for Latin American politics. From the ousting of Maduro to the ongoing oil blockade of Cuba to Javier Milei revving up a chainsaw at CPAC. Various leaders in different countries are taking different approaches to their relationship with the US. Each is aware that there is a high value in being close to Trump, but also each know that Trump won't be the US President forever. So how should we understand the different approaches being taken? Today we talk to James Bosworth, who is the the founder of Hxagon, a company that does political risk analysis and research primarily in Latin America. He is also the author the Latin America Risk Report newsletter. Our conversation with Bos covered what he calls the "orange shift," a region-wide realignment towards dealmaking with the Trump administration. We discuss how Latin American leaders are dealing with inflation, why Mexico's Claudia Sheinbaum and El Salvador's Nayib Bukele are so popular, how Brazil's Lula has surprised economic observers, and whether Trump will be able to find a "Delcy" elsewhere in the region.

Not too long ago, search engines were the dominant form of querying the internet. But that's changing since the rise of large language models like ChatGPT, Claude, and Google's Gemini. More and more people are getting their online info through AI, effectively bypassing the search bars of old and creating a tension for large tech companies that offer AI models, but also make money from web traffic and search-related advertising. In this episode, we speak with Elizabeth Reid, VP of search at Google. Liz has been with the company for more than two decades, witnessing multiple tech transformations in that time. So we talk with her about how Google is incorporating Gemini into search via AI overviews, what that means for traffic and ad sales, and the practical experience of search in an age of LLMs and internet slop.

When it comes to the history of oil and energy, nobody is more famous or well respected than Daniel Yergin. He is the Vice Chairman of S&P Global, and the Pulitzer Prize winning author of both The Prize: The Epic Quest for Oil, Money, and Power and The New Map: Energy, Climate, and the Clash of Nations. So we had to get his insights on the war in Iran, and its historical significance. Yergin tells us that a "different world" will emerge from the crisis surrounding the closure of the Strait of Hormuz, regardless of the war's ultimate outcome. Iran's ability to control the Strait against a much stronger military is a demonstration that the balance of global power is changing, with profound ramifications for countries around the world. We discuss how different regions are being affected, and how it will change their calculus when it comes to energy security. We also talk about the AI industry's seemingly insatiable demand for electricity, and how this is rippling across the entire energy landscape.

He's done it again. On Sunday night, building supply company QXO announced that it would be acquiring TopBuild for $17 billion. TopBuild sells and installs insulation for both the residential and commercial markets. For Brad Jacobs, the CEO of QXO, this is just the latest in a lifetime of deals he's made. In fact, he's made over 500 deals in his life across numerous public companies that he's founded, most of which have XO somewhere in the ticker. Brad's companies all tend to be highly focused on the so-called "old economy" or real physical world, but of course, as we've seen with the datacenter boom, the old economy is still hot and crucial. So we talk about the logic behind this deal, how the insulation market works, and the general state of the building supply market right now.

The White House wants gasoline prices to be lower, and it wants to see American oil companies drill for more oil. But of course, these ideas are in tension. If prices are going lower, why drill more? This tension has only grown sharper since the shale busts of the mid-2010s, as American producers got burned multiple times by prioritizing production over profits. So what now? How do US producers think about the recent oil price spike? How are they thinking about the rising costs of their own production, due to higher energy, labor, and steel costs? On this episode, we speak with Jack McClendon, the founder and CEO of Siena Natural Resources, an independent oil and gas company that primary buys odd lots of wells from other companies. We talk about the long-term economics of the industry, including the central role of capital markets in determining how the industry moves. He also tells us whether the show Landman is realistic.

Everyone knows that new technologies can be really disruptive to the labor market, but eventually new jobs emerge and things come back into balance. And there is a sense in which many view AI with the same lens. Yes, there will be pain in some sectors, but then there will be productivity gains and new sources of demand and new opportunities for labor that we can't conceive of yet. But could it be different this time? Could AI be disruptive in a manner that, say, the steam engine was not? On this episode we speak with Alex Imas, a professor at the University of Chicago focusing on economics and applied AI. We talk about his work on the AI and labor question, how to think about which jobs may be most at risk, and why the sheer speed of AI development could make it categorically different than prior general purpose technologies that came before it.

There are a lot of things to be annoyed about in modern life. The high cost of food and housing and childcare. Dating apps that don't seem to work. The fear of AI replacing you at your job. These are all common complaints and concerns, and each of them can be traced to a specific economic phenomenon or market structure issue. Once you start thinking about the world in this way, you can't unsee it. In this episode, we speak with Planet Money co-host Mary Childs, and contributor to the podcast, Alex Mayassi. They've just written a book called Planet Money: A Guide to the Economic Forces That Shape Your Life. We discuss how one of Tracy's childhood memories was a reflection of the commodity trap, what Baumol's cost disease tells us about daycare, and why -- despite all these frustrations -- there are still many reasons to be optimistic about economic progress.

It's possible that the war in Iran could reshape financial flows in significant ways. Perhaps the Gulf states will end up as less desirable places to do business. Perhaps Iran will have a tollbooth at the Strait of Hormuz. Perhaps this episode will accelerate the world's shift away from oil. It's impossible to say. But given the uncertainty, fresh questions are being raised about the existing financial world order, upon the top of which the US dollar sits. On this episode, we speak once again with Brad Setser, the Whitney Shepardson senior fellow at the Council on Foreign Relations. We discuss how the war is already creating new global imbalances, and the degree to which this episode parallels past energy shocks. We also talk about broader trends in reserve management, other factors driving financial flows, and the unique situation facing East Asia, which is seeing a surge in its energy import bills at the same time its making making a fortune selling chips for the AI boom.

The war in Iran has caused the price of all kinds of commodities to surge, and that has a negative economic impact almost everywhere. But the squeeze is really being felt hard in East Asia, which is the ultimate destination for a lot of oil and gas that come out of the Gulf. And though the Strait of Hormuz may eventually re-open, and the acute pain may pass, this episode may already be reshaping the future. On this episode of the podcast we speak with Alex Turnbull, an investor based in Singapore, and a researcher on energy topics with the Australian National University. He argues that the war will accelerate the region's appetite to restart nuclear power plants, ultimately lessening its dependence on imported natural gas. He also notes that per his channel checks, the region is already seeing a jump in demand for electric vehicles, with BYD dealers holding less and less inventory on hand.

It's fueling the A.I. bubble, it's coming to your retirement portfolio—and it's flashing a lot of warning signs right now.

In the wake of the 2008 financial crisis, private credit or “shadow banking” grew as an alternative to the regulations and shared risk that institutional banks operate within. What happens if a crisis hits the trillions of dollars that are outside of those guardrails? We may be about to find out. 

Guest: Tracy Alloway, co-host of Bloomberg's Odd Lots podcast.

Regardless of whether the war with Iran continues, it seems likely to have a lasting impact on the Gulf states. They may have to rebuild damaged pipelines and other infrastructure, or create new ones that bypass the Strait of Hormuz. They might have to spend more money on their own defense, or intensify a push to diversify their economies away from oil. New political alliances may be formed, and old ones could fall apart. In this episode, we bring back Ziad Daoud, chief emerging markets economist at Bloomberg Economics, to discuss the many ways the war could impact the region for years to come.

Stocks have gone up over the years because corporate earnings continue to grow. That part is straightforward. But in addition to rising stock prices, we've also seen rising stock market valuations. For years, investors have talked about stocks being unreasonably priced, and yet they haven't reverted to historical norms. But perhaps there's a good explanation for this, beyond just animal spirits. Jonathan Heathcote is an economist at the Minneapolis Federal Reserve Bank, who recently co-authored a paper titled, A Macroeconomic Perspective on Stock Market Valuation Ratios. Along with co-authors Andrew Atkeson and Fabrizio Perri, they argue that while stocks may look rich on metrics like price-to-earnings ratios, they look a lot better when based on free cash flow. In other words, because companies haven't had to invest much, their equity is more valuable. Furthermore, labor's share of the profits — the percentage that goes to workers relative to capital — has been on the decline. Of course, these days the big story is about how big, profitable tech companies are spending a fortune on capital expenditure for the AI buildout. So we talked to Jonathan about his research and discuss the possibility that this trend in free cash flow growth could reverse, and therefore hit stock market valuations, too.

When the conflict with Iran started, some of the first headlines we saw had to do with shipping insurance. Marine insurers were said to be canceling war risk coverage for vessels going through the Strait of Hormuz. Premiums were said to surge. Meanwhile, the Trump administration announced it would offer its own insurance for ships traversing the Persian Gulf, in an effort to get things moving again. So why is insurance such a crucial part of maritime trade? And how does the system actually work? In this episode, we speak with Dorothea Ioannou, CEO of the American P&I Club, and Steven Ogullukian, the club's reinsurance director. We talk about the different roles of insurers, reinsurers, insurance clubs, and why ships need to have separate coverage for things like war, liability and hull loss.

Right now, when you think about prediction markets, you basically think about two main companies: Polymarket and Kalshi. And then when you think of what's being traded on those platforms, there's a whole range of stuff from elections to sports to real economic outcomes, to totally gonzo random stuff, like who will win the next season of Big Brother. So far, sports is where a lot of the money is. But at least in theory, prediction markets could be a popular instrument for professional, institutional traders. Thomas Peterffy is the founder and chairman of Interactive Brokers, one of the most successful and groundbreaking electronic brokerages for both institutions and serious retail traders. Now Interactive Brokers is getting into the predictions space. In this episode, we talk to Peterffy on why he believes prediction markets will be the next big thing in markets, why he thinks his firm could be a major player, and what it will take to transform the space from a large curiosity to something seriously used by institutions.

The relationship between the US and Europe is deteriorating along both security and economic dimensions. The Trump administration has imposed tariffs, while also being sharply critical of NATO allies. So what are European leaders to do? Hope things go back to normal in the US? Or perhaps become closer with China? Our guest on this episode says the latter would be a grave mistake. This episode was recorded live on April 1 at the DC headquarters of the Council on Foreign Relations. We spoke with Gina Raimondo, now a CFR Distinguished Fellow, who previously served as the commerce secretary in the Biden Administration, and prior to that was the governor of Rhode Island. She discusses her view that European industry is being hollowed out by China, and that the only path forward is a global, unified, non-China trading bloc, which is an idea that's being thwarted by the Trump administration. We also talk about the legacy of the CHIPS Act, and her fears about AI creating mass unemployment and destabilizing our democracy.

There's obviously a lot of talk these days about AI and possible destruction of white collar jobs. Intuitively bankers might be expected to be victims of this. But before we can answer whether AI can disrupt an industry, or a line of work, we have to know what the job actually entails. What do investment bankers actually do, and why are they paid for it? To answer this question, we speak with Scott Bok, the longtime former CEO of the investment bank Greenhill. Scott is also the author of the book Surviving Wall Street: A Tale of Triumph, Tragedy, and Timing. We discuss how the industry changed in his career, what type of people thrive in it, and how AI could change the nature of the profession.

When you consider the fact that many people don't know how and where to place a comma, it's safe to say that AI is already better than most people at writing. It's clean copy. It can be surprisingly persuasive. And sometimes, it's even informative. But there's frequently still something about it that just seems... off. Many people can tell quite quickly when they're reading AI-generated text. And beyond the style, the existence of AI generated text has all kinds of ramifications, from making it easier for students to cheat, to the rise of deceptive chatbots, to potentially degrading the experience on sites like Reddit. So how do you actually tell if a piece of writing was generated by AI? On this episode, we speak with Max Spero, the CEO of Pangram Labs, a company that built software to detect whether a piece of content was AI generated or not. We talk about the advanced techniques they use, the risk of false positives and false negatives, and what AI writing means in general for the future of the Internet.

Oil has shot up by a lot since the start of war with Iran. But it could still get much worse. So far, the massive disruption (due to the closure of the Strait of Hormuz) has been cushioned by the drawing down of inventories and distributions from strategic stockpiles. Meanwhile, there is some oil still on tankers that has yet to be delivered. According to Bloomberg Opinion columnist Javier Blas, the potential remains for oil to go much, much higher. On this episode, we speak with Javier about the scale of the shock, why the pain is extraordinarily high in East Asia, how this compares to past oil shocks, and what the world would look like if Iran retains control of the Strait.

This week, NASA is scheduled to launch Artemis II, a mission that will send astronauts around the moon for the first time in more than 50 years. But this comes at a time when the space agency is facing some pretty big funding challenges, as well as growing competition with private players like SpaceX. In this episode, we speak with Alexander MacDonald, who served as NASA's first chief economist and is now a senior associate at the Aerospace Security Project at CSIS. We talk about why the space agency had economists, how space exploration is funded, and how NASA measures its own economic impact. Please note, this episode was recorded March 10.

When we last spoke to Marco Argenti, chief information officer at Goldman Sachs, we were talking about how the bank was deploying AI, including the development of its own internal tools. But that was a year and a half ago and a lot has changed since then, especially with the arrival of agentic platforms like Claude Code. So what exactly is Goldman Sachs doing with AI now? And what has its experience with the new tech been like so far? On this episode, we catch up with Marco to discuss what AI deployment at the bank actually looks like at the moment — including how AI coding is changing the work of its developers and engineers — to all the data challenges and regulatory concerns that come with integrating this technology at scale.

The last big story right before the war in Iran started was the collapse in the relationship between the Pentagon and Anthropic, with the latter objecting to any potential use of its models in either fully autonomous weapons or domestic surveillance. Of course, this story immediately become more relevant with the start of the war, and the reporting that Anthropic's technology was in fact utilized at the start of hostilities. But what does that mean? How are these models used? And what would a fully autonomous weapons system actually entail? On this episode, we speak with Paul Scharre, the executive vice president and director of studies at the Center for a New American Security. He has written two books on the subject of AI in warfare, and previously worked inside the Department of Defense on some of these very questions. We discuss the future of autonomous weaponry, and the various ethical and technological dimensions such weapons would entail.

Ripple effects from the war in Iran and the closure of the Strait of Hormuz continue to widen. There's yet another brewing shortage, this time in helium. While most people associate helium with balloons and funny voices, the element is used in a surprisingly wide variety of industrial settings, including semiconductor production, where its role in advanced lithography has been growing rapidly. But helium mining and exploration in North America has been practically non-existent for a variety of reasons. And while the US used to have a strategic helium reserve, the government started selling that down in the late 1990s. On this episode, we speak with Nicholas Snyder, the founder and CEO of North American Helium, which does helium mining in Canada. We discuss the properties of helium that make it so useful, as well as the difficulties of expanding global production and distribution.

Markets are often said to be "headline-driven," but that cliché has rarely felt more true than it does right now. A single tweet or Truth Social post can send prices sharply higher or lower, and investors (especially in the rates market) have been forced to rapidly reposition in response. But even as volatility has increased, traditional safe haven destinations like gold haven't been rallying. So how are big accounts actually trading this market? In this episode, we bring back Ozan Tarman, vice chair of global macro at Deutsche Bank and someone who meets regularly with large investors around the world. He tells us what he's seeing right now, including the potential for a squeeze higher in equities and left-tail risks in private credit.

Everyone knows by now that war in Iran is curbing the flow of oil around the world. But oil isn't just a gasoline and jet fuel story, of course. It's also a crucial feedstock for a bunch of petrochemicals, including the building blocks of a variety of plastics. And we're already seeing polyethylene prices start to surge, with some producers in Asia declaring force majeure and curbing their output. So how much of the world's petrochemicals supply is now in danger? And what does it mean for the future of plastics and packaging, which is basically in everything nowadays? On this episode, we're joined by Philip Geurts, chemicals and oil analyst at BloombergNEF, to walk us through the numbers.

Nobody knows when or if AI will lead to mass displacement of white-collar work. But the anxiety is clearly here now, and there's very little evidence that our politicians are taking it seriously. Of course, there are at least two questions operating at once here. The first is whether or not AI really poses a significant threat to the existing labor market. And then the second one is about the correct policy response. This was the subject of a recent Odd Lots episode recorded live at SXSW in Austin, Texas. In this conversation, we were joined by David Shor, a political consultant, pollster and founder of Blue Rose Research, as well as Byrne Hobart, the writer of TheDiff newsletter, and a general partner at Anomaly Fund, an early-stage venture capital firm. We discuss the prospects of a labor market disaster, what David's polling says about the public view, and possible policy considerations that could be palatable to both industry and the general public.

Dubai has become a huge destination for the rich, with an influx of high-net-worth residents driving up property prices and boosting the UAE's tax revenues in recent years. And of course, Gulf countries more broadly have a lot of oil wealth that they've ploughed into everything from real estate to private credit and tech. But the situation with Iran looks set to test that prosperity. In recent weeks, Iran has been attacking Gulf energy infrastructure and even launched drone strikes on residential areas in Dubai and Abu Dhabi. In this episode, we speak with Hiten Samtani long-time Dubai resident, founder of Ten31 Media, and publisher of The Promote about what's behind Dubai's luxury boom, how Gulf capital has reshaped global finance including private credit, and what life in Dubai feels like amid rising geopolitical risk.
