TL;DR

The UK government is trying to tempt Anthropic into a larger London footprint, with proposals ranging from an expanded office to a dual UK/US listing. The pitch comes as the £300bn (380bn) AI lab feuds with the Pentagon and President Trump over its refusal to relax restrictions on military use of its models.

A Gap in Sovereign AI

Officials at the Department for Science, Innovation and Technology have drafted the proposals for Anthropic chief executive Dario Amodei, who visits Britain in late May on a European customer and policy tour. Downing Street is backing the effort, which accelerated after the US defence department branded Anthropic a “supply-chain risk” and Trump called its leadership “leftwing nut jobs” for maintaining red lines on warfighting use cases.

London mayor Sadiq Khan followed up in writing, pitching the capital as a “steadfast” base for the company. Anthropic already employs around 200 people in London, 60 of them researchers, and last year brought in former prime minister Rishi Sunak as a senior adviser.

Where This Fits in UK AI Strategy

The approach to Anthropic sits alongside a broader push to shore up the UK’s AI capability. Last month the government announced a £40 million (million) state-backed lab for blue-sky AI research in science, healthcare and transport. OpenAI has committed to making London its largest research hub outside the US, and Google is completing a roughly £1 billion (.3 billion) King’s Cross campus more than a decade after acquiring DeepMind.

The honest subtext, acknowledged privately by officials, is that Britain has no homegrown frontier lab to rival the Americans. The strategy is partnership, not competition — tie the best US labs to UK infrastructure, research base and talent pipeline before other European capitals do.

Looking Forward

A dual listing remains, in the words of one insider, “the dream” rather than a realistic scenario, particularly with Anthropic expected to IPO in the US as early as this year. Business secretary Peter Kyle stressed the real target is talent and investment rather than stock exchange optics. For UK businesses, the more immediate question is whether a bigger Anthropic presence translates into faster enterprise rollouts, stronger local support and the kind of ecosystem effect DeepMind delivered for London’s research community.
