Intel’s woes wipe out $1 trillion of semiconductor market cap in one day — PC market bloodbath leaves few chip stocks unscathed

What happened

According to Tom's Hardware on 30 October 2026, Intel's shares plunged 30% on Friday, wiping out nearly $150 billion of market capitalization in a single day — the largest single-day loss in the company's history — following a disappointing financial outlook largely driven by an anticipated drop of more than 20% in sales at Intel's client computing and physical AI group (CCPG). According to intraday estimates by Benzinga, approximately $1 trillion in semiconductor market capitalization was wiped out on Friday. The PHLX Semiconductor Sector Index (SOX), which tracks 30 major semiconductor companies, plunged 9.14%, or 1,052.82 points, to 10,465.38 points as of 2:31 PM ET. Stock moves: Arm -12.68%, AMD -12.48%, Qualcomm -12.14%, Applied Materials -8.73%, ASML -8.13%, Lam Research -8%, Micron -7.28%, Broadcom -7.1%; Nvidia lost 5.66%, about $270 billion, more in absolute dollar terms than Intel. The downturn extended to server makers and cloud companies: Dell -12.67%, HPE -8.10%, Supermicro -6.96%, Oracle -6.88%; Apple fell only 1.66%. Fundamentals: CCPG generated $8.1 billion in Q3 2026 revenue, down 5% year-over-year and 9% sequentially; weaker demand and increased competition cut client processor shipments 14% year-over-year, partially offset by a 9% increase in average selling prices; CCPG accounted for nearly half of Intel's revenue of around $16.5 billion. As strong server processor demand only partially offsets declining client sales, Intel guided Q4 revenue to between $15 billion and $16 billion. Intel expects the client market to deteriorate further in Q4 2026 and into 2027 as elevated memory prices and shortages of other components impact PC prices and demand, and expects the client PC market to decline 10% in 2027 compared to 2026. Intel's market capitalization has dropped nearly 50% from its mid-June peak of $673.43 billion to $338.91 billion, including $148.68 billion in one day.
