Key Highlights

● Investors are punishing big AI spenders despite strong demand.

● AWS Revenue of $45.98 billion beat expectations.

● Microsoft beat on its Azure cloud business.

● Intel's Data Center and AI revenue rose to $7.3 billion.

A senior market analyst summed up the week's mood. "The message from investors is becoming clearer: strong AI Demand is no longer enough on its own," she said. She also said, "Global markets are ending an exceptionally busy week on a cautious note."

That caution turned into a selloff on Friday, October 30, 2026. The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average dropped 572.25 points to 51,770.31 and the Nasdaq Composite lost 747.73 points to 25,437.00, its worst day since June.

Spending outpaces cash

The problem for investors is not demand. Amazon (NASDAQ:AMZN)'s cloud unit, AWS, posted revenue of $45.98 billion, ahead of expectations, and Microsoft (NASDAQ:MSFT) beat on its Azure cloud business. Intel (NASDAQ:INTC)'s data center and AI revenue rose to $7.3 billion.

The problem is cost. Alphabet (NASDAQ:GOOGL)'s third-quarter free Cash Flow came in at negative $9.1 billion, far worse than the negative $3.5 billion expected, as Capital spending rose to $51.4 billion. Amazon's trailing 12-month free cash flow was negative $42.4 billion, compared with positive $14.8 billion a year earlier, and the company signaled that capital spending would rise again next year from about $220 billion in 2026. Meta (NASDAQ:META) reported its first negative quarterly free cash flow since 2012.

The market's verdict

Alphabet had its worst day ever on Thursday, losing about $500 billion in market value, and fell again on Friday. Amazon dropped on Friday after a steeper premarket slide. Meta and Alphabet are both well below their 52-week highs, according to market data.

Microsoft fared better. Its shares were roughly flat on Thursday, and a market strategist said, "Microsoft's AI spending was rational and measured, and it has remained cash-flow positive." Even so, Microsoft slipped on Friday, as Market data tied the move to its plans to raise $25 billion in bonds.

Strategists weigh in

Other strategists described a more selective market. "The love-hate relationship with tech and AI continues, and investors are becoming more discerning following earnings," said a senior market strategist, according to market data. A trading specialist said, "A lot of them kind of got ahead of themselves. It's all Earnings based and right now, they're not producing."

An Investment strategist said, "The earnings bar is very high." The analyst added, "This could remain a significant headwind for the Nasdaq".

Intel's cash-burn warning compounded the pressure on Friday, setting off a global chip rout. The Philadelphia Semiconductor index plunged to 10,688.80. Money flowed into energy, consumer staples, utilities and health care instead.

Fed Chair Kevin Warsh struck a related theme at his press conference. "Market participants are becoming somewhat more discerning in their capital allocations," he said.

What to watch

Apple (NASDAQ:AAPL) reports on Monday, November 2, and Palantir (NASDAQ:PLTR) reports the same day after the close. Investors will watch how those companies talk about AI spending and returns.

The midterm elections on Tuesday, November 3, add a political angle. An investment manager said of a Democratic sweep, "I think that will be seen as negative for both the AI names". The October jobs report on Friday, November 6, and the Federal Reserve's December meeting, where markets are pricing in a rate hike, will shape financing costs for companies that are borrowing to build.
