Computer-chip designer Nvidia has been boosted by big tech firms keen to expand their AI capabilities, despite dealing with US and China tensions.

On Wednesday it reported $46.7bn revenue (£34.6bn) for the second three months of the year, a 56% surge from the same period in 2024.

But Nvidia, which has been caught in the crossfire of a trade war between the US and China, said it "continued to work through geopolitical issues" and its shares fell in after-hours trading.

The company has had to navigate the Trump administration's fast-changing policies aimed at ensuring the US remains ahead in AI development.

Nvidia's sophisticated chips have been an important part of the AI boom.
