Oxford spinout Fractile is raising approximately $600 million at a pre-money valuation of $6.5 billion, representing a more than six-fold jump from the $1 billion valuation it set in May when it closed a $220 million round led by Accel, Founders Fund, and Factorial. The valuation surge follows an initial agreement to supply Anthropic with roughly $250 million of Fractile’s SRAM-based inference chips, with both sides signaling intent to expand the partnership.
The deal marks a significant milestone for European AI infrastructure ambitions. Fractile, spun out from Oxford University, has developed SRAM-based inference chips designed to dramatically reduce latency and power consumption compared to traditional GPU-based inference. The company targeting the chips for production deployment in 2027, positioning them as a potential alternative to NVIDIA’s dominance in the AI inference market.
Anthropic’s decision to partner with Fractile reflects broader industry efforts to diversify AI compute infrastructure beyond NVIDIA. The startup’s SRAM architecture offers advantages in inference workloads where memory bandwidth and low latency are critical. Industry analysts note that the deal signals growing acceptance of specialized inference chips as viable alternatives to general-purpose GPUs for certain AI workloads.
The valuation jump from $1 billion to $6.5 billion in just three months represents one of the fastest growth trajectories in AI chip startups. Fractile’s CEO emphasized that the Anthropic partnership validates the company’s architectural approach and opens pathways for additional enterprise customers. The funding will support scaling manufacturing partnerships and expanding engineering teams ahead of production ramp.
For the AI industry, the Fractile-Anthropic deal underscores a emerging trend: hyperscalers and leading AI labs increasingly seeking alternatives to NVIDIA’s offerings. With GPU shortages continuing to constrain AI deployment scale, partnerships like this could reshape the inference infrastructure landscape through 2027 and beyond.
