1 / 4Britain's sovereign AI fund joins Fractile's round at about $6.5 billion, before its chips ship in volume×

The round

Fractile, the London maker of inference chips that put SRAM memory beside the compute, has closed a round of about $700 million at roughly $6.5 billion, the Telegraph reported on Sunday, after Bloomberg reported talks in August; the price is up from about $1 billion earlier this year. Companies House filings show about £577 million of Series C shares allotted between September 9th and October 23rd, at prices from £707 to £1,452 a share.

Who joined

Lightspeed and Redpoint led, Thrive Capital joined, and so did the UK's £500 million Sovereign AI Fund, at a price slightly below the final one.

The product

Fractile has an initial deal to sell Anthropic about $250 million of chips and expects data center deployment in 2027. It has not shipped in volume.

The catch

A public fund that usually writes £1 million to £10 million checks is now holding a pre-production hardware company that re-priced sixfold in five months. Fractile and the government declined to comment.
