AI Chip Startup Etched Closes $300M Series C at $10.3B Valuation, Defying Early Skepticism

What happened

Etched, an AI chip startup developing ASIC chips specifically for transformer inference without relying on GPUs, closed a $300M Series C round at a $10.3B valuation. The founders are three Harvard dropouts who left in 2022. This is a completed funding event — prior reports from about a week ago indicated negotiations at a potential $20B valuation.

Context and impact

Etched is built on the thesis that GPUs are unnecessarily generalist for AI inference and that specialized ASICs can be orders of magnitude more efficient for transformer models. The round validates top investor interest in Nvidia alternatives at the silicon level. The lower valuation ($10.3B vs. the rumored $20B) reflects market expectation correction, but the close itself confirms viability.
