U.S. stocks looked like they had only edged lower at Thursday’s close: the S&P 500 fell 0.30% to 7720.39, the Nasdaq Composite fell 1.38% to 26184.73, and the Dow Jones Industrial Average fell 0.25% to 52342.56. But the real story came after the close: Amazon fell about 7% after hours, Intel fell about 23%, and during today’s Asian session, Nasdaq 100 futures fell another 1.72% to 29053.25, while S&P 500 futures fell 0.68% to 7701.50.

The three giants are really telling the same story: the market is starting to reckon with the pace at which artificial intelligence is burning through cash. Alphabet plunged 12.6% on Thursday, its biggest one-day drop on record, wiping out about $500 billion in market value in a single day. Its earnings report showed AI capital expenditures pushing free cash flow into negative territory. Amazon’s capital expenditures in the third quarter were $77.3 billion, about 31% above market expectations, with free cash flow at negative $42.4 billion and full-year capital expenditure plans of $220 billion. Intel’s third-quarter revenue was $16.5 billion, up 21% year over year, while revenue from its data center and AI division was $7.3 billion, up 78%. But its fourth-quarter outlook was just $15 billion to $16 billion, well below the expected $17.29 billion.

Put simply, capital expenditures are the real money a company spends on its future, while free cash flow is the cash it has left after those expenses. For the past two years, the market has only asked, “How much have you invested in AI?” Now it’s starting to ask, “When will that money pay off?” Revenue hasn’t collapsed, and cloud businesses are still growing: Amazon Web Services’ third-quarter revenue was $46 billion, up 39.3% year over year. But spending is outpacing earnings, and that’s at the root of this week’s revaluation of tech stocks.

Interestingly, money hasn’t left the stock market; it has just moved elsewhere. On Thursday, more than 400 of the S&P 500’s 500 constituent stocks rose, Dow Jones Industrial Average futures were essentially flat, and the 10-year U.S. Treasury yield eased to around 4.92%. Microsoft’s $25 billion bond offering also attracted strong demand. Asian markets followed the decline today, with South Korea’s KOSPI falling nearly 4% and the Nikkei 225 dropping 2.87%, but the losses were concentrated in the same names tied to the AI ecosystem. This isn’t widespread panic; it’s a rotation: money is shifting away from tech giants “burning cash for growth” and toward companies with sturdier cash flows and less expensive valuations.

The risk comes with tonight’s regular-session trading: after-hours losses aren’t closing prices, and after-hours trading is thin and naturally volatile. Whether Amazon and Intel can recover some of their after-hours losses tonight will be the first test. If they can’t, and the Nasdaq 100 continues to lead the declines, the rotation could escalate into a broad flight to safety. If they recover during the session, it would suggest the market is simply repricing cash burn, not disproving the AI story. Looking further ahead, when other giants report next week, the market will measure them by the same yardstick: Has the growth in capital expenditures peaked, and when will free cash flow turn positive? If they can’t answer those questions, the losses won’t be confined to just one company.
