Etched raised $700 million at a $21 billion valuation in a Series D led by Jane Street, doubling the startup's worth in 26 days after a $10.3 billion valuation in late July, according to the company's announcement.
The round was anchored by Jane Street, which deployed Etched's first shipped AI cluster system at its operations. The trading firm led the capital raise after the successful installation of what Etched calls a frontier-scale inference hardware rack, marking the startup's first completed customer delivery.
Etched builds custom silicon designed for AI inference workloads. The startup closed a $300 million Series C in late July at a $10.3 billion valuation. The pair of rounds separated by four weeks occurred as demand accelerates for specialized hardware in the AI market, where inference, the process of running trained models on data, has become a critical bottleneck as enterprises scale deployment.
Jane Street typically deploys capital only after extensive internal validation. Its role as both lead investor and first production customer means the system met the firm's operational requirements rather than remaining at the prototype stage.
The valuation jump tracks the scarcity of proven AI hardware alternatives. Nvidia's dominance in GPUs has driven startups to pursue custom silicon for specific workloads, but few have moved from design to customer-ready products. Etched's claim of a shipped system places it ahead of most competitors in the inference hardware space who remain in tape-out or early production phases.
Etched did not disclose the size of Jane Street's allocation within the $700 million round or whether the trading firm took a board seat. The startup's burn rate and path to profitability remain undisclosed.
