(SeaPRwire) –   Per a Financial Times report, the UK government is actively pursuing Anthropic, the creator of the Claude AI chatbot. The British government aims for the firm to enlarge its operations in the nation, identifying a potential opening after a disagreement arose between Anthropic and the US Department of Defense.

The British government’s suggestions involve increasing the size of Anthropic’s current London office and seeking a dual listing for its stock. The UK’s Department of Science, Innovation and Technology is formulating these strategies.

The department’s work is supported by Prime Minister Keir Starmer’s office. It is anticipated that these proposals will be presented directly to Anthropic’s CEO, Dario Amodei, during his scheduled visit to the UK in late May.

Requests for comment from Reuters were not answered by either Anthropic or the UK’s Department of Science, Innovation and Technology.

Why the US and Anthropic Fell Out

Anthropic was classified by the US government as a risk to the national-security supply chain. This decision was based on the company’s stance against allowing its Claude AI to be utilized for US military surveillance or autonomous weaponry.

This classification resulted in the company being added to a US blacklist. Inclusion on such a list can limit a company’s opportunities to collaborate with US government bodies and their contractors.

Anthropic responded with legal action. A federal judge in the US has provisionally halted the enforcement of the blacklisting as the legal proceedings continue.

The company has additionally initiated a separate lawsuit that directly contests the supply-chain risk designation. This second case is currently pending.

What the UK Is Offering

The UK’s strategy is part of a wider campaign to draw leading AI firms to its shores amid international doubts about US technology policy.

A dual stock listing would enable Anthropic’s shares to be traded on a UK stock exchange in addition to any potential US listing. This would provide UK-based investors with direct opportunities to invest in the company.

An enlarged London office would bolster Anthropic’s physical footprint in Europe. The UK’s AI industry is already expanding, and the government has publicly prioritized drawing AI investment.

The Financial Times report did not indicate if Anthropic has reacted favorably or unfavorably to the UK’s proposals.

The formal presentation of these offers is likely to occur during Dario Amodei’s UK visit in late May.

With the US blacklist temporarily suspended by the court, Anthropic’s legal status is still undetermined. The company’s future decisions are expected to be influenced by the results of the two active lawsuits.
