Key Highlights

● Four tech giants spent more than $200 billion in the third quarter.

● Alphabet's Capital spending reached $51.4 billion.

● That was up $6.5 billion from the prior quarter.

● Higher financing costs could absorb more cash.

The scale of the artificial-intelligence buildout came into focus this week. "Together, Amazon (NASDAQ:AMZN), Google, Microsoft (NASDAQ:MSFT) and Meta (NASDAQ:META) spent more than $200bn in the third quarter alone," said a market analyst, according to market data. She also warned that "the risk is that higher financing costs will absorb more of the cash generated."

That warning resonated on Friday, October 30, 2026, when stocks had their worst session since June. 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.

Where the money went

Each company's results showed the strain. Alphabet (NASDAQ:GOOGL), Google's parent, reported capital expenditures of $51.4 billion for the third quarter, up $6.5 billion from the prior quarter. Its free Cash Flow came in at negative $9.1 billion, much worse than the negative $3.5 billion expected.

Amazon said 2026 capital spending would stay at about $220 billion and signaled another increase next year. Chief Executive Andy Jassy said, "On the CapEx involved to grow the way we're talking about, it's meaningful." The company's trailing 12-month free cash flow was negative $42.4 billion, compared with positive $14.8 billion a year earlier.

Meta, which reported the previous week, posted its first negative quarterly free cash flow since 2012. Microsoft raised $25 billion in a Debt sale even as it reported a large cash-flow beat.

What the spending buys

The money goes largely into data centers, chips and the infrastructure needed to train and run AI models. Demand for those services is strong. Amazon Web Services posted Revenue of $45.98 billion, ahead of the $45.29 billion expected, and Microsoft beat on its Azure cloud business.

A market strategist said, "Microsoft's AI spending was rational and measured, and it has remained cash-flow positive." Others are less convinced the payoff will come quickly. "The message from investors is becoming clearer: strong AI demand is no longer enough on its own," said a senior market analyst, according to market data.

The analyst's concern about financing reflects the interest-rate backdrop. The Federal Reserve left its benchmark rate range unchanged at its October 27-28 meeting, but markets are pricing in a December hike, according to CME FedWatch data cited by market data. On Friday, St. Louis Fed President Alberto Musalem said, "I judge that additional firming of Monetary Policy will be necessary, and soon."

When companies borrow to fund spending, higher rates raise the cost of that debt. Corporate Bond spreads widened on Friday, according to ICE BofA data cited by market data.

The market reaction

Alphabet had its worst day ever on Thursday, losing about $500 billion in market value, and fell again on Friday. Amazon dropped on Friday. Intel (NASDAQ:INTC)'s cash-burn warning added to the pressure, sending the Philadelphia Semiconductor index plunging to 10,688.80. The Nasdaq-100 lost roughly $2 trillion in Market Value in October, according to market data.

What to watch

Apple (NASDAQ:AAPL) reports on Monday, November 2, offering another view of how a major technology company is approaching AI spending. Palantir (NASDAQ:PLTR) reports the same day after the close.

Investors will also watch the October jobs report on Friday, November 6, and the Fed's December meeting, since both will shape borrowing costs. The midterm elections on Tuesday, November 3, add another variable, with investors watching state and local races for implications for data-center construction. The question the analyst raised, how much of the cash generated will go to financing costs, is likely to stay in focus.
