A single shortage is reshaping the stock market in two very different directions: one chipmaker is surging while the world's most valuable consumer-tech company is reeling.
Micron, which makes the memory chips increasingly demanded by AI systems, jumped about 15%, according to CNBC, after soaring prices from a memory crunch led to a quadrupling of its revenue. The American Bazaar reports that the rally pushed Micron's market value past that of Meta.
The same chip shortage cut the other way for Apple. The company announced price hikes on MacBooks and iPads — its first formal move to pass higher memory and storage costs on to consumers. Investors reacted harshly: according to MacKenzie Sigalos of CNBC, Apple stock closed down 6.15% on Thursday, its worst fall since April 2025 and, CNBC notes, its worst session in more than a year.
The broader market split down the middle. Yahoo Finance reports the Dow rose while the S&P 500 and Nasdaq slipped, as Micron's surge was offset by Apple dragging Big Tech lower.
Behind the swings is what The Verge calls "RAMageddon" — a memory-chip crisis so severe that, in the outlet's framing, even Apple's famously deep pockets and huge purchasing volume couldn't fully absorb it. ZDNet reports the price increases stem from surging memory-chip costs and tight supply.
There's a note of caution, too. Investing.com frames Micron's gains as a test of confidence in the broader AI capital-spending cycle — the question of whether sky-high AI investment can keep justifying these valuations.
Why it matters: the AI boom isn't just lifting chipmakers — its hunger for memory is now raising the price of everyday laptops and tablets, putting the cost of the AI race directly onto consumers' receipts.
