## Key points

- AI shares led a global market sell-off.
- Brent crude rose 4% to $113.17 a barrel.
- US bond yields fell as investors sought safer assets.

## Summary

AI-related shares fell sharply on Thursday, dragging markets lower around the world, while oil prices climbed amid uncertainty over the war with Iran. The sell-off reflected investor concern about the high cost of building data centres and buying chips, as well as doubts that years of rapid growth have left some technology stocks too expensive.

In the US, the S&P 500 fell 1.2% and the Nasdaq 2.6%, although most other US shares rose and the Dow was nearly flat. Nvidia dropped 4.4%, Meta fell 7% and chip-equipment maker Lam Research lost 11.8%, despite reporting stronger-than-expected revenue and profit. Brent crude rose 4% to $113.17 a barrel, its highest level in five months; Asian indexes also fell, while US Treasury yields declined as investors sought safer assets.
