Etched raised $700M at a $21B valuation — led by Jane Street after the quant fund deployed and tested an Etched inference cluster in its own data center. The valuation tripled from $5B in December and nearly doubled from $10.3B in July, driven by validated hardware that combines a custom low-voltage prefill chip with cluster-scale shared memory for decode.
Details
Etched, an AI inference hardware startup, closed a $700M round at a $21B valuation on August 18, 2026, nearly doubling its July valuation of $10.3B in a single month. The round was led by Jane Street, which had already installed an Etched frontier inference cluster in its own data center before making the investment — a rare case of a sophisticated financial counterparty validating hardware before writing the check. The technical story behind the valuation centers on two custom components. For the prefill phase (processing the prompt and context), Etched built a low-voltage chip that packs more transistors without heat issues, enabling faster token processing. For the decode phase (generating output tokens), Etched created cluster-scale memory — a shared low-latency memory pool across multiple chips that allows them to act as a unified compute unit. Etched has shed its original model-specific design; the systems now run any frontier model. Jane Street confirmed: 'We tested the chip and are pleased with early results. Etched's unique approach to inference delivers the precision we need for our most demanding workloads.' Investor roster spans Andreessen Horowitz, Sequoia, Kleiner Perkins, Blackstone, Tiger Global, Bain Capital Ventures, and Peter Thiel. The valuation trajectory — $5B (Dec 2025) → $10.3B (Jul 2026) → $21B (Aug 2026) — is one of the fastest step-up sequences in AI hardware history.
