British chip startup Fractile is closing in on a $6.5 billion dollar valuation after landing a 250 million dollar Anthropic deal

Fractile, a London based startup building specialized AI inference chips, is in advanced talks to raise roughly 600 million dollars at a 6.5 billion dollar pre money valuation, according to Bloomberg reporting. That's more than six times higher than the roughly 1 billion dollar valuation the company landed just three months earlier in a 220 million dollar Series B round led by Accel, Founders Fund, and Factorial Funds, and the entire jump traces back to a single new customer commitment.

Anthropic has signed an initial deal to buy approximately 250 million dollars worth of Fractile's chips, with both companies discussing plans to expand that contract further down the line. Fractile was founded in 2022 by Walter Goodwin, an Oxford trained roboticist, and its core technical bet involves what the company calls memory compute fusion, placing compute and memory directly on the same die using SRAM rather than fetching data from separate off chip DRAM the way conventional GPUs currently operate. That architectural choice specifically targets the data movement bottleneck between processor and memory that limits how fast large language models can actually run inference at scale.

Fractile claims its architecture could eventually run large language models up to 100 times faster than existing hardware while cutting operational costs by roughly 90 percent, figures that come directly from the company itself and haven't been independently verified in any real production deployment. That caveat matters quite a bit here, since Fractile's chips aren't expected to be ready for actual commercial use until 2027, meaning Anthropic's 250 million dollar commitment is fundamentally a bet on unproven, currently non existent silicon rather than a live, active supply relationship the way it might sound at first glance.

This deal makes Fractile the fourth major chip supplier in Anthropic's broader hardware portfolio, joining existing arrangements with Google's TPUs, including a 3.5 gigawatt agreement announced back in April, Amazon's Trainium chips, and Broadcom. Anthropic's own compute spending runs an estimated 19 billion dollars annually, and even a 30 to 40 percent inference cost reduction from a successful new chip architecture at that kind of scale would represent enormous absolute savings, which explains why a frontier AI lab's customer commitment alone, even for chips that don't exist yet, is apparently enough to reprice an entire startup by more than six times in the span of three months
