Fractile, a British startup building chips for artificial intelligence, is in advanced talks to raise money at a valuation more than six times what it fetched three months ago, Bloomberg reported. The jump follows a deal to supply chips to Anthropic.

The company is raising funds at a pre-money valuation of $6.5bn, according to people familiar with the matter cited by Bloomberg reporters Rebecca Torrence and Dina Bass. It expects to bring in about $600mn in the round. That figure includes some money invested at a lower valuation, the people said. A pre-money valuation measures a company’s worth before the new cash lands, so the round would push the headline figure higher still once it closes.

The round has not closed, and details could change, the people said. Fractile and Anthropic both declined to comment.

Six times the May price

Fractile raised a $220mn round three months ago. The venture firms Accel, Founders Fund and Factorial Funds led that deal. It gave the startup a valuation of around $1bn, Bloomberg reported at the time. Fractile said at the time that it was raising money to bring its first AI chips to market.
