TL;DR:

• Industry advisers are pushing back on the UK’s £500 million Sovereign AI Fund, arguing it tilts toward building domestic AI champions when the more immediate problem is low AI adoption inside UK firms.
• Industry data suggests only about one in six UK businesses has adopted AI in core operations; SMEs cite cost, compliance and ROI uncertainty.
• Vendors argue that “optionality” — the ability to switch between OpenAI, Anthropic, Google and domestic models — is a stronger long-term strategy than trying to replicate a full AI stack onshore.

The fund has been presented as a tool for national resilience, but the critique from practitioners is that resilience without adoption is hollow. George Tziahanas of Archive360 warned that governments risk overextending on sovereignty while advances in commercial tools from abroad accelerate away.

The adoption gap, not the infrastructure gap

Tarek Nseir of consultancy Valliance was blunter, telling IT Brief the “UK’s real challenge is working with [US] providers to make sure the right infrastructure is in place for enterprises” rather than building national substitutes. He cited OpenAI pulling Stargate UK and the continuing debate over Palantir’s NHS work as evidence that the policy conversation is crowding out vendor-relationship management that could yield near-term productivity gains.

This matters because it maps directly onto the scepticism Resultsense has reported elsewhere: half of UK executives surveyed by Accenture now expect AI to cut net employment, and UK SMEs remain cautious about adoption. Building a domestic model ecosystem is expensive; closing an adoption gap is a different — and in the short term more tractable — policy problem.

Concentration risk is real, sovereignty is the wrong answer

The fund’s defenders argue, with some justification, that concentrated dependence on a handful of US compute and model providers is a supply-chain risk at state level. Recent reporting on Claude Mythos access negotiations between Anthropic and both the EU Commission (via Reuters) and UK banks (via The Guardian) underlines how much commercial gating sits with a small number of firms. But vendors are warning that strict localisation adds compliance complexity without guaranteeing the UK leapfrogs ahead on capability.

Looking forward

The fund’s first visible moves — an equity stake in Callosum, compute access for Prima Mente, Cosine, Cursive, Doubleword, Twig Bio and Odyssey — align more with the infrastructure-and-champions thesis than with the adoption-first critique. Watch for how much of the £282 million complementary R&D programme flows toward adoption-side problems (skills, procurement templates, SME-facing tooling) rather than model building. That ratio will indicate whether DSIT has heard the pushback.
