## Summary

US technology shares fell sharply as investors questioned whether the rising cost of building AI systems will deliver enough returns. Intel’s warning of a weaker computer market, despite increased AI spending, deepened the sell-off, while Amazon and Alphabet also came under pressure.

The Nasdaq opened down 2.5%, its lowest level in more than two months. Intel shares fell as much as 30%, putting the company on track to lose more than $130bn in value; finance chief David Zinsner said it did not expect positive cash flow this year and forecast a PC slowdown through at least the first half of next year. Amazon’s reported earnings missed expectations, while Alphabet lost more than $500bn in value on Thursday after saying its AI summaries were affecting core search advertising revenue.
