UK-Backed AI Chip Startup Fractile Reaches $7B Valuation in $720M Series C

Fractile, a London- and Bristol-based AI chip startup, has been valued at $7 billion after securing $720 million in a Series C round that included backing from the British government, making it one of the UK’s most valuable technology startups.

The round was led by Thrive Capital, Founders Fund, Lightspeed and Redpoint, with participation from Google’s venture arm CapitalG, BlackRock, DST Global, Elad Gil, Balderton, SV Angel, Britain’s Sovereign AI fund and the British Business Bank.

Fractile is developing chips designed to improve AI inference, the process by which AI models generate responses, and says its technology delivers faster performance while reducing energy use and costs. The company plans to release its first commercial chip next year.

The deal signals confidence in Britain’s push to build domestic AI infrastructure rather than relying solely on overseas computing power, and reflects growing investor interest in AI hardware, a market dominated by Nvidia and a small group of Asian manufacturers.

AI Minister Kanishka Narayan said Britain has too often produced world-leading scientific ideas only to see the resulting technology, industry and wealth built elsewhere, and that the government is determined to change that. While the UK is home to chip designer Arm, its semiconductor manufacturing industry remains small compared with the US and Asia.
