Chip startup Olix raises $312m at $3.3bn valuation, backed by UK gov’t Sovereign AI venture fund

AI chip startup Olix has raised $312 million in a Series B financing round, more than tripling its value from six months ago to $3.3 billion.

The fundraise saw participation from Arm, Fundomo, Hudson River Trading, and Netflix co-founder Reed Hastings, with the UK government’s Sovereign AI venture fund also announcing it had invested in the startup.

The Series B round comes hot on the heels of Olix’s February 2026 fundraise, which saw the UK-based company raise $220m at a $1bn valuation.

Olix said the financing will help fund the delivery of its first chip to customers in H2 2027, whilst also supporting the build-out of its custom silicon platform and allowing the company to meet its manufacturing and supply chain commitments.
