A Catalyst For The AI Bubble Break

AI Summary. Historically, controlling for valuations, a 1% rise in the share of the market represented by initial public offerings has been associated with roughly a 4% decline in prices. With large artificial-intelligence company listings expected and share issuance exceeding buybacks, equity supply could shift from shrinking about 1% a year to growing near 5%, implying returns roughly 20% below average.

Ben Inker and John Pease GMO
Date Posted:
September 25, 2026

GMO estimates net US equity supply could increase by ~5% or more of total market capitalization over the next year. Inker and Pease note that in 1999–2000, “IPOs peaked at ~5% of total market cap. It doesn’t take much new supply to overwhelm the market.”

How does rising equity supply from new listings affect stock returns?

Core argument: Controlling for valuations, a 1% increase in the market share of IPOs has historically led to an approximate 4% decrease in prices, a multiplier the author applies to a coming surge in equity supply.

Controlling for valuations, a 1% increase in the market share of IPOs has historically led to an approximate 4% decrease in prices [Exhibit 2 in gallery]. Consider what is happening to equity supply. SpaceX’s non-Elon sales alone exceed 1% of the U.S. stock market’s value. We are likely to see IPOs from both Anthropic and OpenAI—together valued at about 5% of the U.S. stock market’s total investable market cap —over the next 12 months. For the first time in twenty years, with the brief exception of the GFC, we are seeing net dilution in the U.S. stock market (i.e., share issuance exceeding share buybacks), as the hyperscalers continue their capital expenditure spree. In aggregate, we are going from a world where equity supply was shrinking by roughly 1% per annum (with buybacks exceeding primary or secondary issuance) to one in which equity supply will be increasing by close to 5%, if not more. If you believe the 4x multiplier [implied by the regression line in Exhibit 2], this means we should expect returns that are some 20% below average (roughly 6% real) over the next 12–18 months from the headwind of rising equity supply alone.

  1. Controlling for valuations, a 1% increase in the market share of IPOs has historically led to an approximate 4% decrease in prices, a multiplier the author applies to a coming surge in equity supply.
  2. U.S. equity supply is shifting from shrinking roughly 1% a year, with buybacks exceeding issuance, to growing close to 5% or more, the first net dilution in twenty years apart from the Global Financial Crisis.
  3. Anthropic and OpenAI, together valued at about 5% of U.S. investable market cap, are likely to go public within 12 months, while SpaceX’s non-Elon sales alone exceed 1% of the U.S. stock market’s value.

Carbon Pricing’s Impact on Global Industry Is Quietly Growing

AI Summary. Direct carbon pricing—carbon taxes and emissions trading systems—now covers about 30% of global emissions, with most coverage coming from emissions trading systems in China and the European Union. The EU complements its system with a Carbon Border Adjustment Mechanism that prices carbon on certain high-emitting imports regardless of where they are produced.

Bridgewater argues that carbon pricing is increasingly becoming an industrial-policy tool, with measures such as the EU’s CBAM supporting domestic producers by limiting carbon leakage, while carbon prices encourage investment in energy efficiency and industrial upgrading.

How much of global emissions does carbon pricing now cover?

Core argument: Direct carbon pricing, spanning carbon taxes and emissions trading systems, now covers roughly 30% of global emissions, with most of that coverage coming from emissions trading systems in China and the EU.

Carbon pricing schemes have continued to grow over the last few years. Some form of direct carbon pricing now covers ~30% of global emissions—spanning both carbon taxes and emissions trading systems. Most coverage comes from emissions trading systems in China and the EU, and these schemes are increasingly being adapted to fit their specific industrial policy goals. For example, as a complement to its domestic emissions trading system, the EU has started to implement a Carbon Border Adjustment Mechanism (CBAM), which imposes carbon pricing on certain high-emitting imports regardless of where they are produced. In a world of modern mercantilism, policy makers have increasingly emphasized the need for carbon pricing schemes to support—rather than constrain—industrial competitiveness.

The Fed Finally Gets It

AI Summary. Federal Reserve officials' assessed risks to their employment and price stability mandates had tended to move together rather than inversely, suggesting common forces were driving both. That pattern has now shifted, with officials more optimistic on growth and employment and less concerned about downside risks than before the pandemic.

Matt Klein The Overshoot
Date Posted:
September 25, 2026

About half of Fed officials now forecast that at the end of 2028 short rates will be “at least as high as they are now.” The underlying reason, Klein proposes, is not supply shocks but a persistent shift in the perceived balance of risks between inflation and unemployment.

Have central bankers' employment and inflation risk assessments stopped moving together?

Core argument: From mid-2022 until now, Fed officials’ assessments of risks to the employment mandate and the price stability mandate tended to move together, consistent with judging that the forces driving unwelcome inflation also threatened the jobs outlook.

From mid-2022 until now, Fed officials seem to have judged that all of the forces responsible for unwelcome inflation also threatened the outlook for jobs. That would explain why their assessment of the risks to the employment mandate and to the price stability mandate tended to move together [see “Aligned Mandate” in gallery]. If “normal” factors such as consumers’ access to credit or businesses’ appetite to invest were driving things, the perceived risks to the inflation and employment mandates would be uncorrelated, or even move inversely to each other. That shift has finally happened. In fact, Fed officials are now more bullish on growth and employment—and less concerned about downside risks—than they have been since before the pandemic. The latest data on private sector balance sheets, borrowing, and asset purchases can help explain why.

The Biggest Hot Potato In History

AI Summary. East Asian economies accumulated large US dollar and euro reserves by building export machines based on undervalued currencies, a strategy one analyst argues has run its course. He contends China should revalue aggressively and return to market-determined prices, since the resulting accounting losses reflect real losses already incurred.

Charles Gave argues that East Asia’s post-1997 model of undervalued currencies, which has generated >5T in FX reserves, has run its course. His prescription is aggressive China-led revaluation to shift purchasing power toward Asian consumers.

Should China revalue its currency aggressively and let markets set prices?

Core argument: Gave argues that East Asia’s strategy of building export machines on undervalued currencies to accumulate large US dollar and euro reserves has run its course.

To accumulate their huge reserves of US dollars and euros, [East Asia] built formidable export machines based on undervalued currencies. [Gave sees] only one solution: to return to market-determined prices as quickly as possible. As the leading economy in the region, China should bite the bullet and say the time has come to revalue aggressively. Yes, Asia will take accounting losses. But that does not greatly matter; the actual losses have already been taken a long time ago.

  1. Gave argues that East Asia’s strategy of building export machines on undervalued currencies to accumulate large US dollar and euro reserves has run its course.
  2. Gave sees a return to market-determined prices as quickly as possible as the only solution, with China, as the region’s leading economy, revaluing aggressively.

Would an AI spending slowdown create deflationary rather than inflationary risk?

Core argument: The author argues the dangerous phase arrives when the AI capex boom slows, removing stimulus just as overcapacity, falling prices, refinancing needs and weaker labor income hit together, with a refinancing wall waiting in 2028.

If AI investment has been masking underlying weakness, a slowdown removes the stimulus just as overcapacity, falling prices, refinancing needs and weaker labor income hit together. A refinancing wall sits waiting in 2028. Failure is over-determined. This moment sits at the intersection of the four forces that have produced the most consequential boom-bust cycles in Western economic history: loose credit, government policy, technology, and real estate. There are, as a result, myriad catalysts, each with a low probability of happening, but which collectively guarantee collapse. That is why the principal risk is deflationary rather than inflationary. An AI bust could transmit through capex, employment, consumption, credit, housing, and asset prices simultaneously.

Nine Percent of GDP

AI Summary. An analysis estimates that for US data center owners to break even on AI investments, the sector would need about $3.725tn in annual compute revenue by 2032 — roughly 9.2% of projected 2032 GDP. The estimate assumes 183 GW of US capacity completed, a $9.61tn capital base, a 10% discount rate, and a 50% operating cash flow margin.

The US AI-buildout is projected to average ~3.6% of GDP over 2025–32. Lustig notes data-center operators will need ~$3.725T in annual compute revenue by 2032, 9.2% of projected GDP, to earn a 10% unlevered return on the buildout.

How much annual revenue must AI data centers generate to break even?

Core argument: Stijn’s baseline estimate holds that data center owners would need $3.725 trillion of annual revenue by 2032 — roughly 9.2% of projected 2032 GDP — to break even on AI investment at a 10% discount rate.

What do you have to believe about future revenue in order for all data center owners to to break even on their AI investment? Using a 10% discount rate, Stijn’s baseline number is 3.725 trillion of annual revenue by 2032, which would amount to roughly 9.2% of projected 2032 GDP. This number is the top line earned from selling compute in aggregate by whoever operates the 182.7 GW of US capacity completed by 2032.2. The assumptions behind that number: 183 GW of U.S. data-center capacity completed between 2025 and 2032. $8.54 trillion of construction cost, grossed up to a $9.61 trillion capital base to account for the return on capital tied up during construction. A 10% discount rate. A 6-year life for IT equipment (68% of cost) and a 20-year life for everything else (32%). A 50% operating cash flow margin.

Booms, Bombs and Bonds: Interest Rates, Part I

AI Summary. Because investors can buy bonds across borders, an investment boom in one country such as the United States can draw in loanable funds from abroad and push up interest rates in other nations. The linkage is not one-for-one, since investors also weigh expected exchange-rate changes and the resulting capital gains or losses.

Paul Krugman Krugman Wonks Out
Date Posted:
September 28, 2026

The nominal 10-year Treasury yield is ~ where it was during the mid-2000s housing boom, but below its level during the late-1990s and early-2000s technology boom. Krugman asks, “If we’re now looking at an even bigger investment boom, why wouldn’t we expect to see interest rates at least that high?”

Does an investment boom in one country raise interest rates abroad?

Core argument: Because investors can buy bonds across borders, an investment boom in the United States draws loanable funds from other nations and pushes their interest rates up as well.

Investors can buy bonds across borders, so an investment boom in the United States can draw in loanable funds from other nations and drive up their interest rates. The international linkage between interest rates isn’t always one-for-one. That’s mainly because investors deciding which nation’s bonds to buy don’t just look at interest rates -- they also take into account expected changes in exchange rates. For example, there was a sharp rise in U.S. interest rates in the early 1980s that was only partially matched by a rise in German rates. The reason was that this was also a period of an extremely strong dollar, which many investors believed (correctly) would prove temporary. So German investors buying U.S. bonds had to set the high interest rates they could earn against the capital losses they were likely to experience when the dollar came back to earth.

Takeaways by Macro Roundup® AI

  1. Because investors can buy bonds across borders, an investment boom in the United States draws loanable funds from other nations and pushes their interest rates up as well.
  2. The international linkage between interest rates is not always one-for-one, mainly because investors choosing among nations’ bonds weigh expected exchange rate changes alongside interest rates.
  3. The sharp rise in U.S. interest rates in the early 1980s was only partially matched by German rates, as German investors buying U.S. bonds set high yields against likely capital losses when the strong dollar fell back.

  • Don’t Draw The Wrong Conclusion From Treasury Yields — Ten-year real yields equal the average expected overnight rate over the next decade plus a term premium, and fiscal credibility or debt sustainability concerns would show up as a higher term premium. With the term premium and inflation expectations contained, the increase in bond yields reflects higher expected long-term overnight rates.

Is China extending travel approval requirements to tech talent's families?

Core argument: China now requires spouses and children of certain AI and chip executives whose work is deemed paramount to state security to obtain Beijing’s approval before traveling abroad, even for short trips, according to people familiar with the matter.

Government agencies have recently begun to share the wider restrictions with affected people, which include prominent startup founders as well as the heads of strategically important companies in AI-related fields. Direct relatives such as spouses and children of certain AI and chip executives, whose work is considered paramount to state security, are now required to obtain approval from Beijing before going abroad even for short trips. That marks a broadening of existing curbs on the freedom of movement of China’s most influential tech talent. While not an outright ban on travel, the new requirement is likely to exert a further chilling effect on a tech sector already facing unprecedented curbs. China has restricted foreign travel for top AI professionals in private firms such as Alibaba and DeepSeek since earlier this year.

The Plaza Accord and Its Relevance for China

AI Summary. China faces three options as external demand weakens: shift a larger share of national income to households so consumption absorbs more output, keep relying on investment despite weak returns, or let production and growth slow. The first requires substantial changes in income distribution and saving incentives; the second risks more debt and excess capacity; the third implies higher unemployment.

“Beijing cannot choose whether China will adjust; one way or another, it will.” Pettis warns Zhongnanhai against postponing rebalancing with another round of debt-financed investment “despite increasingly weak returns.”

What choices does China face as external demand weakens?

Core argument: China faces three options: shift a larger share of national income to households so consumption absorbs more output, keep relying on investment despite weak returns, or allow production and growth to slow.

What it can choose is how painful that adjustment will be. If weaker external demand is met by encouraging more borrowing and domestic investment, regardless of whether that investment is economically justified, China risks postponing the inevitable. China therefore faces the same basic choice Japan confronted, but with deeper imbalances and less accommodating global conditions. It can shift a larger share of national income toward households and allow consumption to absorb more of what the economy produces; or it can continue relying on investment, despite increasingly weak returns; or it can allow production and growth to slow. The first choice requires a substantial change in the domestic distribution of income and the incentives to save. The second risks still more debt and excess capacity and, ultimately, a more painful adjustment. The third implies higher unemployment and weaker growth.

  1. China faces three options: shift a larger share of national income to households so consumption absorbs more output, keep relying on investment despite weak returns, or allow production and growth to slow.
  2. China confronts the same basic choice Japan faced, but with deeper imbalances and less accommodating global conditions, and can choose only how painful the adjustment will be.
  3. Meeting weaker external demand with more borrowing and domestic investment, regardless of whether it is economically justified, risks further debt and excess capacity and a more painful adjustment, while slower growth implies higher unemployment.
