Key Highlights

  • Intel closed down 28.58% at $65.76 on October 30, 2026.
  • The shares suffered their worst day since 1974 after a weak fourth-quarter forecast.
  • Fourth-quarter Revenue is guided to $15 billion to $16 billion, below expectations.
  • Data center and AI revenue rose nearly 80% year over year to $7.3 billion.

Why did nearly 455 million Intel (NASDAQ:INTC) shares change hands on Friday? Because the chipmaker delivered a quarter that beat expectations and then a forecast that badly missed them, and investors reacted with a speed rarely seen in a stock of its size. Intel closed down 28.58% at $65.76 on Friday, October 30, 2026, on Volume about 4.56 times its normal level, according to market data. Market reports described it as Intel's worst day since 1974 and said the drop erased more than $146 billion of market value. Shares had closed the prior regular session at $92.07, according to an Earnings Call transcript summary, and had already fallen about 21% in after-hours trading on Thursday once the results were released.

A beat, then a reset

The third quarter itself was solid. Intel reported revenue of about $16.5 billion, up 21% from a year earlier, and adjusted earnings of 52 cents a share, against company guidance of 38 cents and a consensus estimate of 40 cents, according to market reports. Non-GAAP gross Margin was 44.1%. Chief financial officer Dave Zinsner said it was the eighth straight quarter the company had exceeded its financial expectations.

The problem was the outlook. Intel guided fourth-quarter revenue to $15 billion to $16 billion, against roughly $17.1 billion expected, and adjusted earnings to 25 cents a share, against about 43 cents. Gross margin is forecast to fall to about 38%. Bernstein's Stacy Rasgon called the guidance "extremely weak," and Benchmark's Cody Acree called it "a significant miss," market reports said.

Three issues drove the reset. First, the PC market is deteriorating: Intel expects 2026 PC unit volumes to decline about 12%, with second-half units down more than 20%, and another roughly 10% decline in 2027, as higher memory prices squeeze affordability and PC makers cut inventory. Zinsner said in the earnings release: "Looking ahead, we see the PC slowdown continuing at least through the first half of next year."

Second, an accident at Intel's Fab 28 in Israel led to an extended shutdown that is expected to cut fourth-quarter revenue by about $300 million and gross margin by roughly 200 basis points, with a similar revenue hit possible in the first quarter. Third, Supply limits on substrates and Intel 3 capacity are constraining server processor output.

A ripple through the sector

Intel's warning helped set off a broad chip sell-off. Market reports said the Philadelphia Semiconductor index fell 8.7% during the session, and the Nasdaq Composite closed down 2.84%. AMD (NASDAQ:AMD), Nvidia (NASDAQ:NVDA) and memory makers also fell sharply, as investors weighed what a PC slump and memory cost pressure mean for the wider industry.

What Intel does

Intel designs and manufactures processors for PCs and servers, and it is trying to build a contract Manufacturing business, Intel Foundry, to produce chips for outside customers. Its client computing group sells PC processors, its Data Center and AI group sells Xeon server chips, and its foundry unit runs the factories. Intel is no longer in the Dow Jones Industrial Average, having been replaced by Nvidia in 2024.

Where the Business is strong

Not everything in the report was negative. Data center and AI revenue reached $7.3 billion, up 17% sequentially and nearly 80% year over year, with Operating Margin of 42%, according to a call summary. Zinsner said "demand for DCAI products continues to meaningfully exceed available supply," and Intel signed a supply agreement with Oracle (NYSE:ORCL) Cloud Infrastructure.

Foundry revenue rose 16% sequentially to $6.7 billion, and its operating loss narrowed. Intel 18A manufacturing costs have fallen about 40% since the first quarter, yields are improving, and the 14A process remains on track for production in 2028. The company ended the quarter with about $54 billion of cash and short-term investments after completing a $23 billion Equity offering in August.

Valuation

Intel has negative trailing earnings of $2.42 per share, so it has no meaningful price-to-earnings ratio in market data. Its Market Value after Friday's drop stood at about $347.6 billion. For comparison, Nvidia trades at 25.87 times trailing earnings and AMD at 129.55 times on the same list. Intel's valuation therefore rests on expectations of a future earnings recovery, and Friday's guidance pushed that recovery further out.

Bank of America (NYSE:BAC) cut its rating to Neutral from Buy and lowered its target to $100 from $145, while Jefferies (NYSE:JEF) cut its target to $85, according to market reports. Both targets remain above Friday's close.

The bull case

Bulls argue that the core of Intel's turnaround is intact. Server Demand exceeds supply, 18A costs and yields are improving faster than planned, and the Balance Sheet is well funded. Much of the fourth-quarter shortfall comes from a cyclical PC correction and a one-off factory accident, both of which should eventually pass. A 29% drop resets expectations to a lower bar, and management has said it expects to announce "a couple" of advanced packaging customers over the next two quarters.

The bear case

Bears see a company whose recent rally ran ahead of fundamentals. Market reports noted the shares had risen above $130 in May after a preliminary agreement with Apple (NASDAQ:AAPL) to manufacture some of its chips; Friday's close is roughly half that level. Looking at 2027, Zinsner told analysts it is "probably not a dynamic where we are going to have positive free Cash Flow next year," as Capital spending rises to support Intel 3, 18A and 14A. Bank of America flagged uncertainty about winning external foundry customers, and Jefferies expects the PC inventory correction to last through at least the first half of 2027.

Fab 28 and Foundry Wins

The near-term questions are whether the PC slump deepens, how quickly Fab 28 returns to full output, and whether supply constraints on server chips ease. Investors will also watch for named foundry and packaging customers, any confirmation of the Apple manufacturing relationship, and memory pricing trends that affect PC demand. Intel's fourth-quarter report, due early next year, will show whether the guidance proves conservative. Until then, expect further analyst target cuts and heavy trading as funds rebalance after one of the largest single-day losses in the company's history.
