The UK’s ambitions to become a global hub for artificial intelligence have suffered a significant blow. Anthropic, the high-profile AI safety company backed by Google and Salesforce, has confirmed it will pursue a public listing on the New York Stock Exchange, bypassing the London Stock Exchange entirely. The decision has sent ripples through Whitehall, with the Treasury now reportedly exploring retaliatory measures to deter other tech giants from following suit.
Anthropic, founded by former OpenAI executives, is one of the most closely watched companies in the AI sector. Its decision to list in the US underscores a broader trend: London is losing the battle for technology IPOs. The city has long prided itself on being Europe’s financial capital, but a combination of rigid listing rules, a smaller pool of tech-focused investors, and a risk-averse regulatory climate has driven many high-growth firms to American shores.
“This is a wake-up call,” said Julian Vane, Technology & Innovation Lead. “Anthropic is not just any tech company. It is the poster child for responsible AI development. Its choice of listing venue sends a powerful signal about where the UK stands in the global tech hierarchy. We need to ask ourselves: is our regulatory environment enabling innovation or strangling it?”
The Treasury’s response has been characteristically robust. Sources indicate that officials are drawing up proposals that could include tax incentives for UK-based investors in domestic tech firms, relaxed listing requirements for companies with a dual-class share structure (common among tech founders who want to retain control), and even a potential ‘tech visa’ fast-track for AI talent. There is also talk of a sovereign wealth fund dedicated to investing in cutting-edge technology companies, ensuring they have patient capital without resorting to foreign listings.
But some voices within the industry question whether retaliatory measures miss the point. “The problem isn’t that London is unattractive. The problem is that the US market offers deeper liquidity, a more sophisticated understanding of tech, and a regulatory framework that, while imperfect, is more predictable,” explained Vane. “You can’t solve that overnight with tax breaks. You need a cultural shift in how the City views technology.”
Anthropic’s decision also raises ethical questions. The company has positioned itself as a champion of AI safety, but by choosing New York, it will be subject to US securities law, which some argue is less stringent on corporate governance than UK rules. “There is an irony here,” noted Vane. “A company that talks about aligning AI with human values is choosing to align itself with a market that has historically been less aligned with stakeholder capitalism.”
The UK government has invested heavily in AI, with the creation of the AI Safety Institute and a £100 million fund for AI research. Yet, the disconnect between public policy ambition and market reality is stark. While London remains a global leader in fintech, it has struggled to retain homegrown AI champions. DeepMind, now a subsidiary of Google, was born in London but sold to a US giant. Other notable startups, like Improbable and Thought Machine, have also looked abroad for capital.
For now, the Treasury’s retaliatory measures are still in the drafting stage. But the window of opportunity is narrowing. “Every time a company like Anthropic chooses New York over London, it chips away at the narrative that the UK is a tech superpower,” warned Vane. “If we want to be taken seriously, we need to show, not just talk. The next big AI company might not even consider a London listing unless we change course now.”
The stakes could not be higher. The AI industry is expected to contribute billions to the global economy over the next decade. Without a homegrown listing destination, the UK risks becoming a talent factory for Silicon Valley rather than a hub in its own right. As Vane put it, “We have the talent, the research, and the ambition. What we lack is the conviction to build a market that rewards long-term innovation over short-term profits.”
