Governments Are Trading AI Subsidies for Equity Stakes. The Gulf Got There First

The UK government's Sovereign AI venture fund has taken an equity stake in OLIX, a London-based developer of specialised AI inference chips, as part of a $312 million Series B round that values the two-year-old company at $3.3 billion. It is the fund's fifth equity investment since launch, and it fits a pattern Global SWF has flagged as a defining shift in how governments now approach AI: rather than handing out subsidies and hoping domestic companies capture the upside, states are increasingly taking direct equity positions so they own a piece of the winnings themselves.

OLIX, founded in 2024 by 25-year-old James Dacombe, is developing a chip architecture that splits AI inference workloads across specialised processors connected by photonic interconnects rather than conventional copper links, an approach the company says can improve throughput per megawatt and reduce dependence on high-bandwidth memory, an area currently squeezed by global supply constraints. The round also drew Arm, Hudson River Trading and Netflix co-founder Reed Hastings. The UK government did not disclose the size of its own contribution, but framed the investment as part of a broader push to retain more of the economic value AI infrastructure generates onshore, rather than renting capacity built and owned elsewhere.

For readers tracking the Gulf's own AI investment strategy, the more interesting story is not that the UK is doing this, it is that it is doing it years behind, and at a fraction of the scale of, the state-backed vehicles Gulf governments have already built. Abu Dhabi's MGX, chaired by Sheikh Tahnoon bin Zayed, raised a $49 billion fund earlier this year specifically to take direct equity in AI labs and infrastructure, and has since built positions across all three of the leading US frontier labs. Saudi Arabia's PIF-backed HUMAIN put $3 billion directly into xAI's $20 billion Series E, part of a push that has also put Mubadala inside the most exclusive tier of global AI supply chain governance through the Pax Silica Investor Consortium, while Qatar's sovereign wealth fund was reportedly the first Gulf money into Anthropic and has since anchored further rounds across multiple labs. Kuwait's KIA has taken a similar approach through its involvement in Brookfield's $100 billion AI infrastructure programme.

The distinction Global SWF draws, subsidy versus ownership, is exactly the model the Gulf's sovereign funds have been running since well before this became a recognised global pattern. A subsidy transfers public money to a company with no return beyond hoped-for economic activity. An equity stake means the state captures a direct financial return if the company succeeds, and Gulf funds deployed roughly $66 billion into AI and digital infrastructure in 2025 alone, according to Global SWF's own annual tally, accounting for 43 percent of all sovereign capital invested globally that year, the highest share the firm has recorded for any region.

What has changed is not the strategy itself but who else is now running it. A UK government taking a fifth small equity stake in a domestic chip startup is a meaningfully different scale of ambition than a $49 billion fund with positions across every major US frontier lab, but the direction of travel is the same: governments in London, Beijing and across Europe are converging on an ownership model the Gulf treated as the obvious approach from the outset. For Gulf sovereign funds and the government entities that direct them, that is arguably a validation of the strategy rather than new competition, more state capital chasing equity in AI infrastructure raises valuations across the board, but it does not change the fact that MGX, HUMAIN and QIA already hold the positions that newer entrants like the UK's Sovereign AI fund are only beginning to build toward.

The open question worth watching is whether smaller, later state funds like the UK's can find genuine differentiated equity rather than simply following the valuations Gulf and US capital have already set. OLIX's leap from a $1 billion valuation in February to $3.3 billion six months later shows how quickly that price discovery is moving, and how much harder it becomes for a fund with hundreds of millions, rather than tens of billions, to secure a meaningful stake before the round closes.
