Intel shares suffered their worst trading day in more than half a century on Friday, October 30, plunging 28.6 percent in a single session after the chipmaker warned that the personal-computer market is weakening, its profit margins are shrinking and an incident at its factory in Israel will cut into sales — a warning that dragged down the whole American technology sector and wiped about $12 billion off the value of the United States government's own stake in the company in one day.

A good quarter, and then a warning that erased it

The strange part of Friday's crash is that the quarter Intel had just finished was actually strong. The company reported third-quarter revenue of $16.5 billion, up about 21 percent from a year earlier and ahead of its own guidance, with adjusted earnings of 52 cents a share against about 40 cents expected. Revenue from its Data Center and AI division rose nearly 80 percent to $7.3 billion — the kind of growth investors say they want from a chip company in the artificial-intelligence era.

None of that saved the stock, because investors were looking at what comes next. For the fourth quarter, Intel forecast revenue of only $15 billion to $16 billion, well below the roughly $17.1 billion analysts had expected, according to LSEG figures reported by Reuters and CNBC. Adjusted earnings are expected to be just 25 cents a share, against 43 cents expected, and the company's adjusted gross margin is forecast to fall from 44.1 percent to 38 percent. Revenue from client computing — the PC chips that still pay Intel's bills — fell 5 percent in the third quarter to $8.1 billion and is expected to fall more than 20 percent in the fourth quarter.

Chief Financial Officer David Zinsner explained the problem in one sentence that was repeated across Wall Street all day: “We see the PC slowdown continuing at least through the first half of next year.” Intel blamed high memory-chip prices, as the world's big memory makers devote their production to high-bandwidth memory for AI data centres instead of ordinary PC chips, leaving computer makers — and Intel — squeezed.

The Israel factory incident and the cash problem

A second blow came from Intel's Fab 28 plant in Israel. Reuters estimated that an incident at the factory could reduce Intel's revenue by about $600 million over the fourth quarter and the first quarter of next year, including about $300 million in the fourth quarter alone, as supplies of chips are disrupted. Israeli reporting said an explosion at the plant killed two workers. Intel also told investors it does not expect positive free cash flow in 2027, calling it an investment year as it spends heavily — capital spending is targeted at about $20 billion in 2026 — to build new manufacturing capacity, including its 18A process.

The sell-off did not stop with Intel. The Nasdaq Composite fell 747.73 points, or 2.86 percent, to 25,437.00 — its largest one-day percentage drop since June 5, according to Reuters — while the S&P 500 lost 140.32 points, or 1.82 percent, to 7,580.07 and the Dow Jones Industrial Average fell 572.25 points, or 1.09 percent, to 51,770.31. The Philadelphia Semiconductor Index fell about 7.2 percent, AMD fell about 11 percent and Nvidia about 4.2 percent, Seoul Economic Daily reported, as disappointing results from Amazon on the same day deepened investors' worries about how much money AI companies are spending. Intel's fall alone erased nearly $140 billion in market value, Yahoo Finance calculated.

Analysts cut their targets within hours

Wall Street firms moved quickly. Bank of America downgraded Intel from Buy to Neutral and cut its price target from $145 to $100. At least five other firms — including Northland, Barclays, TD Cowen, Freedom Capital Markets and Evercore ISI — also cut their targets on Friday, according to StockAnalysis data summarised by FinanceFeeds. Bernstein analyst Stacy Rasgon summed up the outlook, in a word quoted in market coverage, as “terrible,” while D.A. Davidson titled its note “Not fixed yet.” Even after the crash, Intel shares are still up roughly 70 to 80 percent for 2026 as a whole, because the stock had risen about 150 percent this year before Friday.

Background: a turnaround that investors stopped believing, for now

Intel, once the dominant maker of PC and server chips, has spent years trying to rebuild under chief executive Lip-Bu Tan, who took over in March 2025. Its strategy rests on two legs: designing competitive chips again, and becoming a contract manufacturer — a foundry — for other companies, backed by American government support. Friday's reaction showed how fragile confidence remains: one weak forecast, driven by the old PC business rather than the new AI business, was enough to knock more than a quarter off the company's value. Yahoo Finance's review of closing prices back to May 1973 found only one worse day in Intel's history — July 5, 1974, during the oil shock, when the stock fell nearly 30 percent.

For readers in the United States, including the large Punjabi and Indian-American community working in technology in California, Washington, Texas and elsewhere, the story matters in two practical ways: technology shares sit inside most retirement and pension accounts, so a 2.86 percent Nasdaq fall reaches ordinary savers, not just traders; and a prolonged PC and chip slowdown is the kind of signal that later shows up in hiring at tech firms and their suppliers.

What happens next

The next test comes quickly. Intel's main rival AMD reports its own results on Tuesday, November 3, after the market close — the first independent check on whether Intel's PC warning is an industry-wide problem or an Intel problem. The October U.S. jobs report follows later in the week. Analysts say the question for Intel is whether Friday was a one-day capitulation or the start of a longer re-rating: the stock closed below even the lowest analyst target of $70, which means the market, for now, is pricing in a worse future than any major firm has put in writing.
