Wall Street's technology sell-off deepened on Friday, October 30, 2026, as disappointing earnings from Intel and Amazon reignited investor doubts about the payoff from the artificial intelligence spending boom. The tech-heavy Nasdaq Composite fell nearly 3 percent in its worst day since June, capping a brutal week for the market's biggest names.
The selling was broad and fast. The Nasdaq Composite dropped 2.86 percent to close at 25,437, its largest one-day percentage decline since June 5, according to market reports. The benchmark S&P 500 fell 1.82 percent to 7,580.07, and the Dow Jones Industrial Average slipped 1.09 percent to 51,770.31. The S&P 500 was on track for its worst day since June, and it broke below its 100-day moving average, a level traders watch closely.
The trigger was a pair of earnings reports released after Thursday's closing bell. Both companies beat some expectations on paper, but investors punished what they saw underneath: weak forecasts, soaring AI infrastructure costs, and cash flow under strain. The reaction capped a week in which Alphabet, the parent of Google, suffered its worst day ever on Thursday, and it left the Nasdaq down 5.3 percent for October, its biggest monthly decline since March 2025.
Intel's Outlook Spooks Investors
Intel was the day's biggest casualty. Shares of the chipmaker plunged roughly 30 percent on Friday, leading decliners in both the S&P 500 and the Nasdaq 100, after it issued a fourth-quarter revenue forecast far below what Wall Street expected.
Intel said it expected revenue of between 15 billion and 16 billion dollars for the final three months of the year, well short of the roughly 17.1 billion dollars analysts had penciled in. The weak outlook overshadowed a third quarter that, on its face, looked solid: revenue of 16.51 billion dollars, slightly above the 16.5 billion consensus estimate, and adjusted earnings of 52 cents a share, ahead of the 40 cents expected.
The details of the quarter told a split story. Revenue from Intel's data center and AI division jumped 78 percent to 7.3 billion dollars, a sign that demand for AI hardware remains strong. But the PC division, still Intel's largest business, generated 8.1 billion dollars, down 5 percent from a year earlier, reflecting pressure in the personal computer market.
Chief Executive Lip-Bu Tan pointed to higher memory prices and limited supply, saying they are making computers more expensive. Morningstar analyst Brian Colello said Intel gave investors "an ugly outlook because weak demand for CPUs and higher memory chip prices are suppressing unit demand," and he cut his fair value estimate for the stock to 85 dollars from 105 dollars.
The plunge erased a huge chunk of Intel's market value in a single session and dragged the entire semiconductor sector down with it. Advanced Micro Devices fell nearly 10 percent in early trading, and other chip names including Broadcom and Micron fell sharply, according to market data. Nvidia, the company at the center of the AI boom, fell more than 4 percent during the session.
Amazon's Spending Worries Investors
Amazon added to the gloom. Its shares fell 5.6 percent on Friday after the e-commerce and cloud computing giant reported third-quarter results that missed Wall Street expectations and laid bare the cost of its AI buildout.
The headline number that alarmed investors was cash flow. Amazon reported negative free cash flow of 42.4 billion dollars over the 12 months through September, compared with positive cash flow of 14.8 billion dollars in the year-earlier period. The company said the swing was driven mainly by investment in AI infrastructure, and it maintained its forecast of about 220 billion dollars in capital expenditure for 2026.
There were bright spots in the report. Amazon Web Services, its cloud division, delivered its fastest revenue growth in nearly five years, with quarterly revenue rising 39.3 percent to 46 billion dollars. The company also reported net income of 20.7 billion dollars for the third quarter. But for a market increasingly focused on when AI spending turns into profit, the cash burn mattered more than the growth.
Reddit suffered a similar fate, with its shares tumbling about 30 percent after its fourth-quarter revenue guidance fell short of expectations. Sandisk fell almost 12 percent even after beating earnings forecasts, amid worry that memory pricing may be nearing a peak. Alphabet, which had plunged about 13 percent on Thursday in its worst day ever, wiping out roughly 475 billion dollars in market value according to Yahoo Finance estimates, slipped about 1 percent further on Friday.
The AI Trade Under Strain
The sell-off is the latest chapter in a debate that has dominated markets all year: whether the hundreds of billions of dollars pouring into AI data centers, chips, and power will pay off quickly enough to justify the valuations of the companies spending it.
That debate has been sharpened by a run of mixed signals. The US economy grew at a 3.4 percent annual rate in the third quarter, according to Commerce Department data released Thursday, and consumer spending rose 3.8 percent. But inflation also picked up, with the Federal Reserve's preferred price gauge rising 3.6 percent in September from a year earlier, well above the central bank's 2 percent target.
The Federal Reserve held its benchmark interest rate steady at a range of 3.75 to 4.00 percent on Wednesday, with two officials dissenting in favor of raising rates now. Markets are pricing in roughly 80 percent odds of a quarter-point rate increase at the Fed's December 8-9 meeting, which would raise borrowing costs further for companies funding massive AI projects with debt.
Beyond stocks, the risk-off mood spread. Bitcoin traded below 77,000 dollars, pressured by the fallout from the massive hack at cryptocurrency exchange Binance disclosed a day earlier. Gold futures fell 3.7 percent to 3,883 dollars an ounce, their lowest level since last September, while oil prices climbed, with West Texas Intermediate crude up 2.4 percent to more than 104 dollars a barrel.
What This Means
For ordinary investors, Friday's sell-off is a reminder of how concentrated the market's gains have become. A handful of giant technology companies now drive so much of the major indexes that a bad earnings day at two of them can pull the whole market down, including retirement accounts and index funds that hold them.
For the AI boom itself, the message from the market is more specific. Investors are no longer rewarding spending alone. Alphabet was punished for burning through cash even as its AI products grew. Amazon was punished despite its cloud division's fastest growth in nearly five years. Intel was punished despite a booming data center business, because its core PC market is shrinking and its outlook disappointed.
Analysts say the market is now asking a harder question: not whether AI will matter, but when the spending turns into earnings, and at what cost. Companies that cannot show a clear path from AI investment to profit are finding that investors have little patience left.
The sell-off also lands days before the November 3 midterm elections, when the cost of living is looming large for voters. Rising prices, high gas prices, and now falling stock prices together paint a mixed picture of an economy that is growing on paper while households feel squeezed, a tension that has defined much of the year's economic debate.
What Happens Next
Traders will now look to the next round of earnings and to the Federal Reserve for direction. The central bank's December meeting is the next major event on the calendar, and any signal about whether rates will rise again could move markets sharply in either direction.
Intel faces a longer road. The company must convince investors that its PC business can stabilize and that its AI and data center momentum can offset weakness elsewhere, even as memory costs squeeze its margins. Amazon, meanwhile, must show that its 220-billion-dollar spending plan is building a durable advantage in cloud and AI rather than simply burning cash.
For now, the market's verdict on Friday was unambiguous. After months in which AI spending was treated as a reason to buy, investors spent the final trading day of October treating it as a reason to sell, and the Nasdaq closed out its worst month in more than a year.
