Britain's Sovereign AI Fund Is Joining Fractile's $6.5 Billion Round, the Telegraph Reports, as Filings Show £577 Million Raised
Updated Nov. 2: The UK government's Sovereign AI Fund is among new investors in a roughly $700 million round valuing London AI-chip startup Fractile at about $6.5 billion, the Telegraph reports, citing unnamed sources; neither Fractile nor the government has confirmed it. Companies House filings already show Series C share allotments between September 9 and October 23, which Tech Funding News totals at about £577 million. Fractile, which has an initial chip deal with Anthropic, has not announced the round or shipped a production chip.
Updated November 2, 2026: We changed the headline, summary and search title so they attribute the Sovereign AI Fund's participation to the Telegraph's unnamed sources, as the report below does. We also corrected a comparison: the C-3 share price of £1,452.35 is nearly twice the C-1 price of £801.54, not about twice. The report is otherwise unchanged.
British taxpayers are buying a stake in an AI chipmaker before it has shipped a chip. The government's Sovereign AI Fund has joined a funding round for Fractile, a London startup designing inference chips, in a deal expected to raise about $700 million and value the company at about $6.5 billion, the Telegraph reported on November 1, citing sources. Fractile has not announced the round, but the paperwork is already public: Companies House shows a run of Series C share allotments since September.
What the filings show#
Fractile's Companies House record lists nine statements of capital following share allotments (form SH01), filed on October 15 and October 28, covering allotments from September 9 to October 23. A resolution filed on October 12 created three new preferred share classes, Series C-1, C-2 and C-3.
Tech Funding News, which read the filings, puts the total at about £577 million, about $774 million: £147.8 million of C-1 shares at £801.54 each, £37.4 million of C-2 at £707.25 and £392.2 million of C-3 at £1,452.35. The filings do not name the investors.
What the Telegraph reports#
According to the Telegraph, the round is led by Lightspeed and Redpoint, with Thrive Capital also investing. Its sources say the Sovereign AI Fund is among the new investors and came in at a slightly lower valuation than the final $6.5 billion. The fund usually invests between £1 million and £10 million per deal, the paper says, so its stake is likely small, but its size has not been disclosed. The Budget gave the fund an additional £60 million from 2027-28, on top of its original £500 million.
Fractile and the government declined to comment, the Telegraph says. It reports that the deal could be announced as soon as next week.
Why the buyers are paying now#
Fractile, founded in 2022 by Oxford robotics PhD Walter Goodwin with Yuhang Song, designs chips that keep memory next to the compute to speed up inference. It has an initial deal to sell Anthropic about $250 million of chips, Bloomberg reported, according to Tech Funding News and the Telegraph, and expects to deploy in data centres in 2027. Tech Funding News found no disclosed revenue.
The filed shares come to more than the round size the Telegraph's sources give, and the three share prices differ widely: the C-3 price is nearly twice the C-1 price. Neither the filings nor the reports explain the gap, though Tech Funding News suggests the lower-priced C-1 and C-2 shares reflect split pricing within the round.
Limits#
- The round is unannounced. The Sovereign AI Fund's participation, the lead investors and the $6.5 billion figure come from the Telegraph's unnamed sources.
- Tech Funding News says Fractile was in talks in August at a $6.5 billion pre-money valuation; the Telegraph says the deal values the company at about $6.5 billion. We could not establish which basis is right.
- We read the Companies House filing index, not each SH01 form. The £577 million total and per-class figures are Tech Funding News's reading of those forms.
- The Anthropic chip order is Bloomberg's reporting, relayed by both outlets, and is described as an initial agreement.
