Etched’s valuation doubles to $21B in a month

AI hardware startup Etched has reached a $21 billion valuation after raising $700 million, doubling its valuation in just one month. The company is developing specialized chips designed to optimize the prefill and decode stages of AI inference.
Why it matters
The rapid valuation growth highlights intense investor appetite for specialized AI hardware that can outperform general-purpose GPUs in inference tasks.
Etched on Tuesday announced that it has raised another $700 million at a $21 billion valuation, led by Jane Street after the famed quant fund tested and bought the startup’s AI hardware.
Even by AI standards, this valuation step-up is jaw-droppingly fast. Etched was valued at $5 billion in December. It raised a $300 million Series C at a $10.3 billion valuation in July . Now investors have doubled its valuation to $21 billion, up nearly $11 billion, in a month.
Etched delivers its AI tech as full systems that it calls “frontier inference clusters.” (Etched competitor Nvidia calls its full systems AI factories).
Co-founder and COO Robert Wachen told TechCrunch that investors are so enthusiastic because Etched has designed two new components from scratch to speed up inference — the computing process that happens after a user submits a prompt.
