Anthropic in Talks to Buy Fractile Inference Chips to Cut AI Operating Costs

British AI chip startup Fractile is developing computing systems designed for inference, the stage when trained artificial intelligence models generate answers and solve problems. Inference speed and cost have become increasingly important as AI companies move from training large models to deploying them at scale, intensifying demand for specialized hardware that can deliver faster responses efficiently.

Fractile has secured a chip supply agreement worth about $250 million with Anthropic, with the systems expected to enter service as early as 2027. Buoyed by the order, the startup is in talks to raise about $600 million in a new funding round that could value the company at $6.5 billion, marking a sharp increase in its valuation.

Surging enterprise demand for Claude has made compute costs, chip supply and energy efficiency central to Anthropic’s expansion. Purpose-built accelerators could let the company co-design silicon with its models and software stack, lowering inference costs while giving it greater control over its hardware roadmap. The effort will supplement, rather than replace, Anthropic’s multi-chip strategy spanning Amazon Web Services, Google, Nvidia and AMD.

Anthropic confirmed on Aug. 6, 2026, that it was assembling an in-house team and recruiting engineers across chip architecture, design and verification to build custom silicon for Claude. Senior openings offer annual pay of $320,000 to $485,000. The company hired Clive Chan, an early member of OpenAI’s chip program, in June, while The Information reported on July 2 that Anthropic was discussing manufacturing with Samsung. No tape-out or production schedule has been announced.

Anthropic has long relied on Nvidia GPUs and computing capacity and custom chips supplied by partners including Google and Broadcom to train and run its Claude models. As model sizes and enterprise demand grow, developing chips in-house could diversify supply risks, lower costs and strengthen Anthropic’s bargaining power with cloud and semiconductor providers.

As of July 19, 2026, Anthropic was evaluating whether to design its own AI chips and was reportedly in talks with Samsung about a custom-chip partnership. The company continues to diversify its supply chain even after recently signing long-term contracts with Google and Broadcom. Its annualized revenue has reportedly surpassed $30 billion, but it has yet to formally settle on a chip strategy.
