Why Intel’s stock is sinking toward its worst day in two years — and a $128 billion wipeout

Intel shares fell sharply, heading toward their worst single-day decline in two years, as investors reacted to mounting pressure on the company's PC business. The selloff erased roughly $128 billion in market value, a striking move for a company long viewed as a bellwether for the broader semiconductor and personal-computer industries.

The core issue is demand. Rising memory-chip prices are weighing on PC sales, since memory is a key component of laptop and desktop costs; when those prices climb, device makers face pressure to raise prices or absorb thinner margins, and buyers often delay purchases. At the same time, corporate IT teams are working with tighter budgets for laptop refresh cycles, adding a second headwind to the client-computing segment.

For markets, the reaction underscores how sensitive Intel's valuation remains to the health of the PC market, even as the company invests heavily in foundry and data-center ambitions. What to watch: whether memory pricing stabilizes in coming quarters, whether enterprise hardware budgets loosen, and whether Intel's newer business lines can offset softer client demand. Those factors will shape how quickly the stock recovers.
