Fractile, an AI chip startup with a supply agreement to Anthropic, is in advanced talks to raise funding at a $6.5 billion valuation, more than six times the $1 billion price it achieved in a Series B round this May.
The valuation jump in under four months comes as investor appetite for chip designers serving the large language model sector has intensified. Fractile's May Series B, which according to reported details included $220 million in capital, valued the company at $1 billion. The current funding discussions place it at 6.5 times that figure.
Fractile designs inference chips for AI workloads, a segment that has drawn venture and strategic capital as major AI labs seek to reduce reliance on hyperscaler GPU availability. The company has discussed preliminary chip supply arrangements with Anthropic for 2027 deployments, though those arrangements remain in early stages rather than finalized purchase commitments.
The fundraising effort occurs against a backdrop of chip-design startups attracting significant valuations. Several competitors in the inference and training silicon space have seen capital rounds in the billions. Fractile's scale and customer discussions position it in a narrower tier focused specifically on optimized inference silicon for large foundation models.
The new funding round follows the May Series B by months, a compressed timeline. Fractile has not announced the close of any new funding as of now.
Fractile's May round valued it at one-fifteenth of the $6.5 billion price currently under discussion. If the company closes at the proposed valuation, it would represent one of the fastest capital appreciations in recent AI infrastructure rounds.
