Meta sell-off drags US tech stocks lower as AI spending fears flare up - Financial Times

A sharp sell-off in Meta shares rippled across US technology stocks, with the Financial Times reporting that investor concerns over artificial intelligence spending weighed on the wider sector. The move highlights how sensitive megacap tech valuations have become to questions about the scale and payoff of AI-related investment.

The development matters because the largest technology companies have driven a substantial share of recent index gains, so weakness in a single megacap name can quickly affect broader market sentiment. When investors question whether heavy AI capital expenditure will translate into earnings, the reaction tends to spread beyond the company at the center of the news. The key issue for markets is not whether AI investment is occurring, but how quickly it can be monetized and at what cost to margins.

What to watch: upcoming earnings commentary on AI budgets and returns, any read-across to other hyperscalers and chipmakers, and whether the selling remains concentrated or broadens. For long-term investors, the episode is a reminder that thematic enthusiasm and valuation risk can coexist.
