Etched
Etched is an AI Accelerators company founded in 2022 and based in Cupertino, USA. It has raised $1.3B in total funding, most recently a Series C in 2026 at a $21B valuation.
Etched was founded in 2022 and is headquartered in Cupertino, USA. The company builds Sohu, a purpose-built silicon chip that hardwires transformer architecture directly into silicon, eliminating GPU flexibility to achieve extreme specialization for inference workloads. According to the company, a single 8-Sohu server can replace a large rack of H100s for transformer inference. Etched has raised $1.325 billion across multiple rounds, including a Series C in August 2026 of $700 million at a $21 billion valuation led by Jane Street.
Etched represents a counterargument to general-purpose GPU acceleration in AI: a high-stakes bet that the transformer will remain the dominant architecture long enough to justify a chip optimized solely for it. The scale of capital deployed—$1.325 billion in total funding—signals investor conviction that specialized inference silicon can capture meaningful share in the $100+ billion AI accelerator market. The company's trajectory from $10.3 billion to $21 billion valuation within one month reflects market appetite for alternatives to Nvidia's generalist approach, even as that strategy carries concentrated architectural risk.
