In a closed-door summit that has sent ripples through the global tech community, former President Donald Trump convened with the chief executives of America’s most formidable artificial intelligence companies this week. The goal: to lock in billions of dollars of domestic AI investment and cement the United States’ lead in the race for artificial general intelligence. But as the champagne was being poured in Silicon Valley boardrooms, a quieter, more anxious conversation was unfolding across the Atlantic. British AI firms, once confident in their post-Brexit agility, are now sounding the alarm over a widening transatlantic tech rivalry that threatens to sideline the UK’s ambitions.
Trump’s gathering, held at his Mar-a-Lago estate, included leaders from OpenAI, Google DeepMind (the US arm), Anthropic, and a handful of emerging hardware players. Sources familiar with the meeting describe a blunt message: American AI investment must stay American. Trump, reportedly flanked by advisors from his previous administration, pitched a vision of ‘digital sovereignty’ wrapped in tariff threats and tax incentives. The subtext was clear: if you want access to US markets and federal contracts, your intellectual property and data centres should remain on home soil.
For UK firms, many of which have deep ties to US venture capital and rely on American cloud infrastructure, this is a wake-up call. The British AI sector, valued at over £17 billion and employing nearly 50,000 people, has long prided itself on cutting-edge research in areas like foundation models, healthcare AI, and autonomous systems. But its commercial viability often depends on US licensing deals or partnerships. If the Trump camp follows through on pledges to tighten export controls or impose a ‘digital border tax’, British startups could be squeezed out of the very market they need to scale.
‘This is a classic zero-sum game,’ said Dr. Eleanor Hastings, a policy fellow at the London Centre for Future Studies. ‘The US wants to build a moat around its AI ecosystem. The UK, for its part, has been caught between the US and the EU, trying to play both sides. But if Trump returns to power, we may have to pick a lane, and that lane might require a lot more domestic investment in sovereign compute and data governance.’
The worry is not just about capital. It is about talent. British AI researchers have long been lured by US salaries and prestige. The so-called ‘brain drain’ is accelerating, with DeepMind’s London office reportedly seeing senior researchers relocate to California or join US-based labs. If the US creates a more protectionist environment, the pull becomes even stronger. ‘We could see a hollowing out of the UK’s AI research base,’ warned a senior executive at a London-based AI startup that wished to remain anonymous. ‘Our VCs are already asking whether they should incorporate in Delaware just to have a seat at the table.’
The UK government, still reeling from the AI Safety Summit it hosted at Bletchley Park last year, is scrambling to respond. Downing Street has quietly accelerated plans for a ‘sovereign AI cloud’ and is reviewing its approach to the regulation of frontier models. But the clock is ticking. The next US election is less than a year away, and regardless of the outcome, the direction of travel is toward tech nationalism.
There is also a deeper, more existential question for the UK. If the transatlantic alliance fractures, where does Britain turn? The EU is moving quickly on AI regulation with the AI Act, but it is a compliance-heavy regime that many British startups find stifling. The Indo-Pacific, including Japan and India, offers alternative partnerships, but the cultural and time zone divides are significant. ‘The UK has to decide what kind of AI nation it wants to be,’ said Hastings. ‘Do we want to be a Silicon Valley satellite or do we want to build our own orbit? Because the US is telling us, quite explicitly, that the days of free riding are over.’
For now, British AI firms are doing what they do best: innovating. They are forging deeper ties with European universities, exploring joint ventures in the Gulf, and lobbying Whitehall for a ‘sovereign AI fund’ that matches the ambition of the US and China. But the shadow of Mar-a-Lago looms large. The message from Trump’s summit is unmistakable: in the new world order, AI is not just technology. It is power. And the UK, once a leader in the enlightenment of reason, is now fighting for a place at a very exclusive table.
As one seasoned tech investor in London put it: ‘We are not even at the starting line anymore. We are trying to get into the stadium.’
