AI Stocks Plunge on Thursday

2026-10-15 13:36 By Andre Joaquim 1 min. read

US equities extended their mixed momentum as pressure on AI infrastructure offset resilience in traditional sectors of the economy.

The S&P 500 fell 0.5% and the Nasdaq 100 dropped 1.5%, its sixth decline in seven sessions.

Chip producers and AI hyperscalers sank further after Anthropic disclosed third-quarter sales figures that slowed from the pace earlier this year and missed most estimates, reinforcing skepticism that soaring expenditure in the sector may not translate into returns.

Micron, Intel, AMD, and Marvell dropped over 6%, while Seagate and Western Digital tumbled 9%.

On top of that, hot producer inflation consolidated bets of a Fed hike this year to add stress on datacenter operators that took record-levels of debt to finance capex, with CoreWeave sinking 8% as its bonds declined sharply.

Still, the Dow gained 0.6% as a rally in Treasuries exemplified the pivot from speculative companies to established sectors.

Walmart added 3% and Eli Lilly gained 2%.
