Etched raises $700M for inference hardware

Etched raised $700 million at a $21 billion valuation after Jane Street tested the company’s inference hardware and put a rack in its data center, according to Etched’s funding announcement and TechCrunch’s account of the round. The valuation has doubled from $10.3 billion in July, turning a specialised inference bet into one of the market’s most aggressively funded hardware stories; operators should file the rack deployment, not the valuation, as the useful evidence alongside the archive’s analysis of the interconnect bottleneck in AI clusters.
