Etched Raises $700 Million as Valuation Doubles to $21 Billion

Founded in 2022 by three Harvard dropouts, San Jose-based Etched is building Sohu, an application-specific integrated circuit designed solely for Transformer inference, with manufacturing handled by TSMC. The bet is that as AI spending shifts from model training to serving models at scale, purpose-built silicon can deliver better speed, power efficiency and cost than general-purpose GPUs dominated by Nvidia. Etched says it has signed more than $1 billion of customer contracts, giving investors a commercial benchmark for a chip still early in deployment.

Etched said on July 23 that it raised $300 million in a Series C at a $10.3 billion valuation, led by Sequoia with participation from a16z, Jane Street, Diffusion and SK Hynix. The price is more than double the $5 billion post-money valuation attached to a $500 million round closed in December 2025. The Wall Street Journal reported on July 17 that Jane Street was discussing a separate financing at about $20 billion, alongside Sequoia’s lower-priced round; neither had closed then, and Etched’s latest announcement did not confirm a $20 billion transaction.

Etched is a chip startup targeting the AI inference market with full systems built around specialized chips designed to accelerate model computation and lower costs. Nvidia has long dominated the AI accelerator market, and Etched’s ability to gain a foothold with manufacturing support from TSMC could influence cloud providers’ purchasing decisions and reshape industry competition.

As of July 20, 2026, Etched said it had completed its chip with TSMC’s support and secured more than $1 billion in cumulative orders. Its latest valuation reached $5 billion. The commercial orders indicate customer adoption of its specialized AI inference solution, but the pace of mass production and its ability to deliver remain critical.
