The UK's Sovereign AI vehicle has taken a nine-figure equity stake in Olix, an inference-chip company founded in 2024 with operations in London and Bristol that has just closed a $220m Series A. The investment was made on 30 July and announced on gov.uk on 3 August, co-published by the Cabinet Office and the business department 1. It is the fund's fifth equity investment since it launched in April with GBP 500m .
Sovereign AI takes shareholdings in British technology companies rather than buying their products, and inference chips are the part of the market where that choice bites hardest. Inference is the running of a trained model rather than its training, and it is where volume demand sits once a model ships. A stake in a company at that layer protects against the outcome ministers keep citing, a promising British firm acquired abroad or cut off from supply, without delivering a single hour of compute to a British researcher on any stated date.
A nine-figure position in a company two years old also concentrates the portfolio rather than spreading it. Five investments in four months, one of them this size, leaves the vehicle's risk sitting in a small number of very young holdings. The government has published no framework setting out when equity is preferred to procurement, which is the gap the Commons science committee identified in July .
