Etched raises $700M Series D at $21B valuation

The round's lead backer is also its first paying customer, a rare alignment that signals real demand for chips built for one AI architecture.

• Etched raised a $700 million Series D led by quantitative trading firm Jane Street at a $21 billion valuation, roughly doubling its worth from a month earlier.
• Etched builds 'frontier inference clusters'—chips, racks and software co-designed to run already-trained transformer AI models cheaply and fast, rather than general-purpose GPUs used for both training and inference.
• Its Sohu chip is an ASIC hard-wired only for the transformer architecture and made on TSMC's N4P process, trading flexibility for efficiency versus general-purpose accelerators.
• Etched says it has secured more than $1 billion in customer contracts and has begun shipping its first server racks, including to lead investor Jane Street.
• Etched's valuation has climbed from $5 billion in December to $10.3 billion in a July Series C to $21 billion now, more than quadrupling in about eight months.
• Having a lead investor double as the launch customer collapses the usual gap between capital commitment and proof of demand, a structure that could become a template for AI infrastructure financing.
