What happened
Nasdaq (^IXIC) fell about 2% on Friday to near 26,100 after a flat open, as AI-debt worries hit chip stocks, with the index on track for a 4% weekly loss. Wall Street started the day almost unchanged, but chip makers and AI data-center firms kept sliding. Investors fear these companies borrowed heavily and may not earn enough to repay the loans; CoreWeave fell about 13.6% and is down roughly 25% this week. Oil also rose 3.1%, to $109.21 a barrel for Brent. The Dow was still heading for a weekly gain as bank stocks rose.
Why it matters
The Nasdaq (^IXIC), which is packed with tech and chip companies, is heading for its worst week since late June because investors are rethinking how much AI spending will pay off. That matters to anyone with index funds or retirement savings, since AI-linked companies carry a lot of weight in them. Higher borrowing costs, with the 10-year Treasury yield (what the US government pays to borrow for ten years) near 5.1%, make debt-heavy firms more vulnerable.
