UK AI chip startup Fractile raises $720 million at $7 billion valuation

British AI inference chip startup Fractile announced on Wednesday (November 11) that it has closed a $720 million Series C funding round, valuing the company at $7 billion. The UK government's Sovereign AI Venture Fund and the British Business Bank joined the round, and Fractile plans to launch its first commercial chip next year.

Funding details and investors

Reuters reported the round was led by Thrive Capital, Founders Fund, Lightspeed and Redpoint, with CapitalG, BlackRock, DST Global and Balderton among the participants. The UK government said the round raised more than £500 million at a valuation above £5 billion — the same round expressed in sterling, rather than a different figure.

First chip due next year

Founded in 2022 and based in London and Bristol, Fractile builds chips designed specifically for AI inference and has yet to ship a commercial product. It plans to release its first commercial chip in 2027. The company claims its architecture can run models 10 or even 25 times faster at a tenth of the cost — claims made by the company itself, with no independent benchmark verification so far.

The UK bets on home-grown AI hardware

The round is the latest step in the UK government's push to build a domestic AI hardware industry, with the Sovereign AI Venture Fund and the British Business Bank both taking part — a sign officials want a home-grown challenger to the US chip giants. Fractile had already drawn the Sovereign AI Fund's attention; this site reported the earlier investment interest on November 1. The round values the company at $7 billion.
