- Companies House filings show that Fractile has allocated £577 million in Series C shares since September.
- Anthropic has placed an initial $250m chip order, according to Bloomberg.
- The company expects to deploy its chips in data centres in 2027.
Walter Goodwin earned his Oxford PhD studying general-purpose robotic intelligence. He moved from robotic manipulation to scaling laws, then to a very specific hardware question: if only a handful of large AI models are widely deployed, are current chips sufficient?
Fractile, the London chip startup Goodwin founded to answer this question, has raised £577m in Series C preferred shares, according to Companies House filings.
Nine share allotment returns (form SH01) filed on 15th and 28th October cover three new share classes: Series C-1 at £801.54, C-2 at £707.25, and C-3 at £1,452.35. The allotments were made between 9th September and 23rd October. At an exchange rate of approximately $1.34 per pound, this equates to around $774 million.
The relevant resolutions established the share classes on 11th September, and the documents were lodged on 12th October. The documents indicate a total of £147.8 million for C-1, £37.4 million for C-2, and £392.2 million for C-3.
On 11th September, the company allocated approximately £450.5 million, with the balance issued in smaller C-3 tranches through to 23rd October. This includes 45,692 shares on 6th October, valued at £66.4 million. All shares were paid in cash, with no outstanding amounts.
These filings came five months after Fractile’s $ 220 million Series B. In August, the UK startup was in advanced talks to raise $600 million at a pre-money valuation of $6.5 billion.
The register total is about $174 million higher. The C-1 and C-2 shares at the lower price align with the split pricing.
A roboticist’s detour into silicon
Goodwin started Fractile in 2022 with co-founder Yuhang Song. The company emerged from stealth in July 2024 with a £12 million seed round, co-led by Kindred Capital, the NATO Innovation Fund, and Oxford Science Enterprises, where Goodwin had worked as an associate.
Fractile designs chips for inference, which is when a trained model responds to a prompt. Instead of moving data between separate memory and processor chips, its architecture keeps data next to the transistors that do the calculations.
For example, Fractile says some long AI workloads now take about a month at around 40 tokens per second. The company aims for 1,200 tokens per second, which would cut that month down to a day.
Why investors are paying before a chip ships
Bloomberg reported that Fractile agreed to an initial deal to sell Anthropic about $250 million in chips, with both parties interested in expanding the agreement. The hardware is not expected until 2027.
Scarcity is driving much of the market activity. Nvidia licensed Groq’s inference technology in December 2025 and hired its founder, Jonathan Ross, along with most of its engineers, in a deal TFN reported was worth tens of billions of dollars. Cerebras went public in May at a valuation above $56 billion. Etched raised $700 million at a $21 billion valuation in August, led by Jane Street, its first paying customer.
London-based Olix raised $312 million at a $3.3 billion valuation that same month, according to Tech.eu. Samsung co-led Dutch startup Euclyd’s €200 million-plus Series A in September. With a $6.5 billion pre-money valuation, Fractile would sit between Olix and Etched, but unlike Etched, it has not yet deployed a chip with customers.
What has to go right
Fractile has not shipped a production chip yet, and TFN found no disclosed revenue. The company expects to deploy in data centres in 2027. The Anthropic order is only an initial agreement, according to unnamed sources.
Fractile has not said how it will use the Series C funds. The Series B was set aside for its first chips and systems and for hiring in London, Bristol, San Francisco, and Taipei. In February, the company pledged £100 million over three years to expand in the UK, including a hardware engineering facility in Bristol.
The real test will be in 2027, when Fractile has to deliver working silicon to a customer with other options. Until then, the valuation reflects both scarcity and technology. The next funding round will tell you which of those two things the investors were most excited about.
