AI Bubble Debate: Is the Trade Popping or Being Repriced?

The evidence this week suggests a trade being tested instead of broken. The Nasdaq 100 climbed 1.1% on Thursday, October 22, with technology shares leading and AI-linked stocks recovering in late trading after solid earnings, even though tech and chip shares had sold off earlier in October and hedge funds had markedly cut their technology exposure.

Warnings have accompanied the gains. A prominent hedge fund founder stated investors were almost certainly in an AI bubble, and the chief executive of BlackRock (NYSE:BLK) warned that delays in building data centers could raise computing costs and slow economic growth.

Meta Earnings: Why Is Spending Outrunning Cash Flow?

Meta Platforms (NASDAQ:META) disclosed results for the third quarter on Wednesday, October 21. Revenue climbed 26% to $64.60 billion, above market forecasts of roughly $63.3 billion, but investment spending including finance leases hit $34.91 billion, up 80%, and free cash flow was negative $2.12 billion against positive $10.6 billion a year earlier.

Meta narrowed its 2026 capex range to $135 billion to $145 billion from $130 billion to $145 billion. A $9.89 billion legal charge cut GAAP earnings to $3.83 per share, against $7.40 excluding the charge.

Alphabet, Microsoft and Amazon: Do Cloud Revenues Justify the Bill?

The bulls point to cloud growth. Alphabet (NASDAQ:GOOGL) disclosed Google Cloud revenue up 82% to $24.8 billion during the second quarter, Microsoft (NASDAQ:MSFT) disclosed Azure growth of 43% with annual Azure revenue above $100 billion, and Amazon (NASDAQ:AMZN) disclosed AWS sales up 37% to $42.2 billion. Microsoft stated demand still exceeded its capacity.

The skeptics point to cash. Alphabet recorded the first negative free cash flow for the quarter in its history, at $5.9 billion, and Amazon's trailing twelve-month free cash flow moved below zero at $7.6 billion. Microsoft continued to be cash generative, with $19.6 billion of free cash flow for the quarter ended in June, on capex of $41 billion.

One July analysis framed the gap bluntly, citing approximately $400 billion of AI infrastructure spending against roughly $100 billion of enterprise AI revenue. It additionally observed that the top ten stocks make up roughly 35% of the S&P 500 versus roughly 25% at the dot-com peak, and that Cisco (NASDAQ:CSCO) traded near 472 times earnings in 2000 against approximately 24 to 26 times anticipated earnings for Nvidia (NASDAQ:NVDA).

Which Reports Could Settle the Bubble Question?

Microsoft and Alphabet report following the trading close on Wednesday, October 28, and Amazon and Intel (NASDAQ:INTC) follow on Thursday, October 29. Investors will assess whether capital spending outlook rises again, whether cloud growth keeps accelerating, and whether free cash flow stabilises.

Meta showed that revenue can beat whereas cash flow weakens. The next four reports will show whether that holds across the spending cycle.
