Fractile seeks $6.5B valuation after Anthropic chip deal

British AI chip startup Fractile is in advanced talks to raise approximately $600 million at a pre-money valuation of $6.5 billion, according to Bloomberg, representing a more than sixfold increase from the roughly $1 billion valuation it secured just three months ago.investing+1

The funding round follows an initial deal between Fractile and Anthropic worth approximately $250 million for the startup's specialized inference chips, with plans to expand the contract in the future. The chips are not expected to be ready for deployment until 2027.Bloomberg Law+2

A Rapid Ascent

Founded in 2022 by Oxford-trained engineer Walter Goodwin, Fractile designs processors that physically interleave memory and compute to deliver low-latency, high-throughput inference — serving AI model responses faster and more cheaply than conventional GPUs. The company emerged from stealth and closed a $220 million Series B in May 2026, led by Accel, Founders Fund, and Factorial Funds.fractile+2

At the time of that round, Anthropic was already in discussions to procure Fractile's chips as part of a broader effort to diversify its hardware supply chain beyond Nvidia ↘ 0.99%.

What's Driving the Valuation Jump

The new $6.5 billion figure is driven largely by the confirmed Anthropic supply agreement, which transformed what had been exploratory talks in May into a binding initial contract. Bloomberg reported that the funding round includes some capital invested at a lower valuation, and that the deal is not yet closed — details could still change.Bloomberg Law+2

Fractile's architecture uses SRAM-based in-memory compute, which the company claims can deliver inference performance up to 25 times faster and at one-tenth the cost of existing GPU-based systems. If those claims hold at scale, the startup could become a meaningful alternative supplier for AI companies facing ballooning compute costs.AI Weekly+1

Broader Context

The fundraise comes amid intense demand for AI inference capacity as companies deploy increasingly large language models. Fractile's rapid revaluation mirrors a broader trend of investors pouring capital into chip startups that promise to break Nvidia's dominance in AI hardware. The round remains ongoing, and the final terms may shift before closing.Bloomberg Law
