Britain moved to convert Anthropic's Washington troubles into a London opportunity on April 5, the same week the Pentagon formally appealed a court ruling that had blocked Anthropic's blacklisting. 1. UK Pitches Anthropic: London HQ and Stock Exchange Dual Listing Britain's Department for Science, Innovation and Technology circulated formal proposals to Anthropic on April 5, offering a London office expansion and a potential dual listing on the London Stock Exchange, according to reporting by the Financial Times. The pitch arrives as Anthropic—valued at $380 billion—fights a Pentagon supply-chain risk designation issued February 27 that has barred it from federal contracts. A US district judge blocked enforcement in March, citing "classic First Amendment retaliation," but the Trump administration appealed on April 2, giving the DOJ an April 30 deadline to file its case. The UK plans to present the proposals to CEO Dario Amodei during his London visit in late May. Anthropic has more than 150 UK employees, including former Prime Minister Rishi Sunak as a senior adviser, and is in early IPO discussions with Wall Street banks.
