Key facts
- Market (Fortune, Oct 31): Nasdaq -2.9%, S&P 500 -1.8% on Oct 30, worst single days since June; Nasdaq-100 companies lost more than $1T; Intel’s weak Q4 guidance added to the fall
- 2026 capex (Fortune): Amazon $220B, Alphabet up to $205B, Microsoft ~$170B, Meta up to $145B, SpaceX (with xAI) up to $88B, together up to $828B; Evercore and Bank of America expect AI capex near $1T in 2027
- Cash flow (Fortune): four of the five had negative free cash flow in Q3 (Microsoft the exception); Meta plans to raise up to $95B by issuing shares; Microsoft sold $25B of bonds, its first in more than nine years
- Commitments (Bloomberg, Oct 30): Alphabet, Meta, Microsoft, Amazon and Oracle hold more than $3T of AI spending commitments over coming years, including Alphabet’s $1T and Meta’s $800B; Reuters: the five returned 9.3% of cash to shareholders in the first three quarters, a 15-year low
- Single stocks (CNBC via Techmeme, Oct 30): Intel closed down 28.58%, its worst day since the 1970s, wiping about $12B off the US government’s stake, after weak guidance; Reddit fell 29.27% on a weak Q4 forecast; S&P cut Meta’s outlook to negative over capex and negative free cash flow, and Meta fell 15% in October
- Credit (WSJ via Techmeme, Oct 30): neoclouds CoreWeave, Nebius and Nscale have ‘effectively been shut out of the bond market in recent weeks’ as lenders demand tougher terms
- Bernie Sanders on X (Oct 30, ~770k views): the companies ‘have racked up $3 trillion in debt on a high-stakes gamble on AI. Big Tech Oligarchs: If your AI bet fails, don’t come begging to taxpayers. You won’t be bailed out — period.’
- Same day: OpenAI’s funding round was reported to have reached only ~$11B of a $30B target (see OpenAI’s funding round falls short of its $30B target)
What happened
The week’s Big Tech earnings showed AI revenue growing fast (Google Cloud doubled, Azure +48%) but capital spending growing faster, with negative free cash flow at four of the five biggest spenders (Microsoft the exception). On Friday Oct 30 investors sold: the Nasdaq had its worst day since June. The same day brought reports that OpenAI’s private round fell short and that Anthropic may not get an investment-grade rating after its IPO.
Why it matters
The labs’ plans rest on hyperscaler capex and on capital markets financing it. A sell-off that also hits private fundraising (OpenAI) and debt ratings (Anthropic) is the first broad sign that the money behind the frontier race has limits; politicians are already framing it as a bailout question.
