Etched raises $700M at a $21B valuation led by Jane Street

Etched has raised $700mn at a $21bn valuation in a round led by Jane Street, doubling the $10.3bn it was worth on 23 July. It has also completed its first customer delivery, a rack shipped to Jane Street.

Etched has raised $700mn at a $21bn valuation, led by Jane Street, and has shipped its first customer rack. The customer is Jane Street.

The valuation has doubled in 26 days. The company was worth $10.3bn on 23 July after a $300mn Series C led by Sequoia, and $5bn in December.

That is roughly four times in eight months, at a company that has just made its first delivery to a paying customer.

Jane Street is not the new arrival the sequence implies. TNW reported in June that the trading firm was already among Etched’s backers, alongside Hudson River Trading, Jump Trading and Two Sigma.

So this is an existing investor increasing its position and taking delivery, rather than a customer converting into a lead. The distinction matters, because the second version is a much better advertisement than the first.

What is genuinely notable is who is funding it. Four proprietary trading firms have backed a company selling inference hardware, in a business where latency converts directly into money.

The design splits the problem in two. A prefill chip runs at low voltage, packing in more transistors without the heat that limits other high-end parts, while decode relies on what the company calls cluster-scale memory, letting many chips share one fast pool.

Etched has spent years shaking off its original premise. It was founded on etching a single model into silicon, and now says its systems run Mixture of Experts designs including DeepSeek and Qwen, and non-transformer architectures such as Mamba.

The commercial base is real but thin. More than $1bn in contracts was signed as of June, and the company’s first chip worked on TSMC’s N4P process at the first attempt, which is not common.

The money is buying the ramp rather than the record. Etched says the round funds factories, supply chains and fleet software on the way to gigawatt scale, and European challengers are chasing the same market, with London’s Olix recently tripling to $3.3bn.
