Spending, prices and financing have run well ahead of proven profits. A sharp correction would not be a surprise.

  1. 1. AI capex vs AI revenue

    Is spending on AI data centers running far ahead of what AI earns?

    Now: Microsoft, Alphabet, Amazon and Meta guide to roughly $720-740 billion of 2026 capital spending, and Meta's free cash flow turned negative in Q3 2026. On the revenue side, OpenAI's annualized revenue was near $50 billion in October 2026, and Bain estimates AI needs $2 trillion a year of revenue by 2030. Unlike 2000, cloud capacity is sold out: Azure grew 48%.CNBC, Oct 29, 2026 (AI capex vs AI revenue, opens in a new tab)Meta Q3 2026 (AI capex vs AI revenue, opens in a new tab)Bain via Bloomberg (AI capex vs AI revenue, opens in a new tab)

    Are stock prices far ahead of earnings?

    Now: The S&P 500 forward P/E was 17.7 on November 5, 2026, its lowest in three years, because earnings estimates rose much faster than prices. The long-run Shiller CAPE is still near 41, close to its 1999 record.FactSet, Nov 2026 (Stock valuations, opens in a new tab)Shiller CAPE (Stock valuations, opens in a new tab)

    Does the market depend on a handful of AI stocks?

    Now: Three stocks made up about 21% of the S&P 500 in October 2026, the most ever, and the ten largest are close to 40% of the index.

    Are suppliers funding their own customers?

    Now: Nvidia invests in OpenAI (a $30 billion stake, after a planned $100 billion deal was dropped in March 2026) and backstops CoreWeave capacity; AMD gave OpenAI warrants tied to GPU purchases; Oracle holds a $300 billion OpenAI contract.

    Now: OpenAI raised money at a $1.25 trillion valuation in November 2026, and Anthropic was valued at $965 billion in May 2026 on a run-rate above $47 billion. That is roughly 15-25 times revenue.

    Will today's chips lose value before they pay for themselves?

    Now: Big tech depreciates servers over 5-6 years, while Nvidia ships a new generation every year. Michael Burry estimates this understates depreciation by about $176 billion over 2026-28.

What could pop the AI bubble?

Bubbles rarely end on valuation alone. These are the triggers analysts watch most.

Revenue disappoints

If AI revenue stops growing fast enough to cover the capex, investors stop paying for future growth. This is the gap Bain sizes at up to $800 billion by 2030.

Capex cuts

If one hyperscaler trims its data center budget, Nvidia, chip suppliers, utilities and neoclouds all lose their biggest customer at once.

Credit stress

Rising default insurance on debt-funded builders such as Oracle and CoreWeave, or a failed bond deal, could cut off the money that pays for the build-out.

A cheaper model

A model that matches the best at a fraction of the compute would cut demand for GPUs and data centers, as DeepSeek briefly did in January 2025.

Rates and policy

Higher interest rates make long-dated AI bets worth less today, and new rules on power, chips or AI use could slow spending.

A circular deal unwinds

If a lab cannot pay a supplier that also invested in it, losses spread through the web of cross-investments.

Frequently asked questions

Is AI a bubble?

Parts of it look like one. On the evidence as of November 13, 2026, the AI Bubble Meter scores 67 out of 100 (bubble territory). Spending, market concentration, circular financing and margin debt look stretched, but unlike in 2000 the leading AI companies earn real and fast-growing revenue, cloud capacity is sold out, and the S&P 500 forward P/E (17.7 in November 2026) is far below dot-com levels.

How does the AI bubble compare with the dot-com bubble?

Today's market is more concentrated than in 2000 and its debt and circular deals rhyme with the telecom bust, but valuations are much lower: the S&P 500 traded at about 18 times forward earnings in November 2026, while Cisco traded near 200 times in 2000. Scored on the same 10 signs, the dot-com peak gets 87 out of 100 against 67 today. After its March 10, 2000 peak the Nasdaq fell 78% by October 2002.

What is circular financing in AI?

Circular financing is when a supplier invests in or lends to a customer that then spends the money on the supplier's products. In AI, Nvidia has invested in OpenAI and backstops CoreWeave, and AMD gave OpenAI share warrants tied to GPU purchases. It inflates reported demand if the customer cannot pay its own way. Lucent and Nortel did the same with telecom start-ups before 2001.

What could pop the AI bubble?

The usual triggers are AI revenue growing too slowly to cover data center spending, a hyperscaler cutting capex, credit stress at debt-funded builders such as Oracle or CoreWeave, a much cheaper model that cuts demand for chips, or higher interest rates. A bubble can also deflate slowly rather than pop, as earnings catch up with prices.

How is the AI Bubble Score calculated?

Each of the 10 warning signs gets a score from 0 (healthy) to 10 (extreme). The AI Bubble Score is their average times ten, from 0 to 100: under 25 is no bubble, 25-44 frothy but grounded, 45-64 a bubble warning, 65-79 bubble territory and 80 or more dot-com mania. Our baseline today is 67; the same signs scored for March 2000 give 87. It is a way to organize the evidence, not a forecast or financial advice.
