Key Highlights

● Intel closed at $65.76 on Friday, October 30, 2026, a record one-day drop.

Intel (NASDAQ:INTC) plunged on Friday, October 30, 2026, closing at $65.76 in what market reports described as the steepest one-day drop on record for the stock. Other outlets called it Intel's worst day since 1974. Trading volume reached 447.8 million shares, far above the average, according to market data.

The selloff set off a rout across the semiconductor industry and was the main driver of the Nasdaq Composite's worst day since June.

A weak outlook overshadows a beat

Intel reported third-quarter results after Thursday's close. Adjusted Earnings of $0.52 a share beat the $0.40 estimate, and Revenue of $16.51 billion was roughly in line. Data Center and AI revenue rose to $7.3 billion.

The problem was the guidance. Intel forecast fourth-quarter revenue of $15 billion to $16 billion, well short of the consensus of $17.29 billion, and adjusted earnings of $0.25 a share, against estimates of about $0.40 to $0.43. It also warned of cash burn this year, citing a weak PC market driven by memory prices and availability, Manufacturing hurdles and heavy production spending. Market reports said that an explosion at Intel's Kiryat Gat factory in Israel cut fourth-quarter revenue by about $300 million.

CEO Lip-Bu Tan described a sudden shift in customer behavior. "In recent weeks, our customers began signaling a PC slowdown based on the memory prices and availability," he said on the call, according to market data. He added: "Our OEM partners are aggressively managing inventory to match the softer sell-through." Intel expects the slowdown to last into 2027.

Tan also struck a more optimistic note: "Despite near-term headwinds across the PC industry, Demand for our CPUs remains robust."

Analysts turn cautious

Bank of America (NYSE:BAC) downgraded Intel to Neutral and cut its price target to $100 from $145, according to market data. An analyst said the "agentic tide" in data center was "more than offset by PC/supply headwinds." One analyst called the guidance "a perfect storm."

The ripple effect

Intel's warning spread quickly. The Philadelphia Semiconductor index fell steeply to 10,688.80. Advanced Micro Devices (NASDAQ:AMD), Qualcomm (NASDAQ:QCOM) and Marvell Technology (NASDAQ:MRVL) all tumbled, while Nvidia (NASDAQ:NVDA) and Broadcom (NASDAQ:AVGO) also fell sharply. PC makers Dell Technologies (NYSE:DELL) and HP Inc. (NYSE:HPQ) plunged on the warning about PC demand.

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. The Russell 2000 slid 47.37 points to 2,811.84. Amazon (NASDAQ:AMZN)'s negative trailing free Cash Flow of $42.4 billion, oil above $100 a barrel and expectations of a December rate increase from the Federal Reserve added to the pressure.

Technology was the worst-performing sector, while energy, consumer staples, utilities and health care rose.

"The message from investors is becoming clearer: strong AI demand is no longer enough on its own," a senior market analyst said.

What to watch

Investors will be looking for signs of whether Intel's PC warning is echoed by other companies. Apple (NASDAQ:AAPL) reports on Monday, November 2, and Super Micro Computer (NASDAQ:SMCI) and Qualcomm report in the days that follow, on November 3 and November 4.

The midterm elections on November 3 and the October jobs report on Friday, November 6, will also shape the backdrop. For Intel, the key questions are how quickly memory pricing eases and whether its cash position stabilizes as the PC slowdown plays out.
