Interactive Brokers Opens UK Retail Access for Anthropic IPO Allocation

Interactive Brokers (U.K.) Limited announced that eligible United Kingdom customers may submit requests for shares in Anthropic, PBC. The participation route operates through a UK Retail Offer managed via Retail Book Limited. Anthropic seeks to float its Class A common stock on the Nasdaq Global Select Market. Because the underlying regulatory registration statement is not yet effective with authorities, shares cannot currently be purchased or finalized, and client allocations remain unassured.
