• Anthropic plans to let UK retail investors buy shares in its upcoming Nasdaq (NASDAQ:NDAQ) IPO through the RetailBook platform.
  • The UK distribution channel is separate from any London listing; the company has not announced a London Stock Exchange (LSE:LSEG) float.
  • The IPO, filed under ticker ANT, is expected in November, but pricing and offering size remain undisclosed.

UK Retail Access in a US Listing

Anthropic is reportedly preparing to let UK retail investors participate in its forthcoming US initial public offering through the RetailBook platform, according to people familiar with the matter. The arrangement would give British individual investors a rare opportunity to buy into a major AI company at the IPO stage, but it does not signal a London stock-exchange listing. The offering is planned for Nasdaq under the proposed ticker ANT, with Goldman Sachs (NYSE:GS) and Morgan Stanley (NYSE:MS) leading the transaction.

The move comes as Anthropic, founded in 2021 by former OpenAI researchers, seeks to raise approximately $100 billion at a valuation that could reach $1.5 trillion to $2 trillion. Bloomberg reported that RetailBook would coordinate the UK retail offering, with other investment platforms submitting orders through it. The company’s filing also envisaged participation by individual investors in parts of continental Europe. However, participating brokers, allocation terms and the size of the UK offer have not been established, and the arrangements remain subject to change.

Financial Scale and Infrastructure Commitments

The IPO filing, amended on November 2, revealed third-quarter revenue of $16.95 billion, up 1,127% year over year, and first-nine-month revenue of $33.24 billion. Despite the rapid growth, Anthropic reported an operating loss of approximately $1.26 billion for the nine-month period. The third-quarter net loss was approximately $23 billion, largely due to noncash accounting charges tied to rising valuations. The company also disclosed $895.4 billion in purchase commitments and lease agreements as of September 30, highlighting the enormous future infrastructure obligations that underpin its AI ambitions.

Growth has slowed sequentially: third-quarter revenue rose about 47% from the prior quarter, compared with 144% in the second quarter. The company boasts more than 14,000 enterprise customers, including roughly 250 that each generate at least $10 million in annual revenue. Still, the path to sustained profitability remains uncertain, and the hefty infrastructure commitments sharpen the investment debate.

Governance Structure Raises Questions

A central feature of the offering is Anthropic’s unusual governance structure. Seven co-founders will hold a special Class F share through “Founder LLC,” carrying 50.1% of general shareholder voting power. Separately, the Long-Term Benefit Trust will have authority to elect a majority of the board. Public investors will therefore receive economic exposure but limited practical control.

Anthropic presents this structure as protection for its public-benefit and AI-safety mission. Critics question whether shareholders can hold management sufficiently accountable when voting power is disconnected from economic ownership. The structure adds another layer of complexity for investors evaluating the IPO.

Valuation and Market Context

Valuation discussions have fluctuated. Reports initially suggested a target of $1.5 trillion to $2 trillion, but Bloomberg later reported that some investors see fair value nearer $1.4 trillion to $1.5 trillion, with approximately $1.75 trillion potentially achievable. These are market indications, not an agreed IPO price. The final price range, share count and offering size have not been disclosed.

The IPO would test public appetite for frontier AI at trillion-dollar valuations. Competition from OpenAI and lower-cost models, including Chinese alternatives, is intensifying. The company raised $65 billion in May 2026 at a reported $965 billion valuation, making the proposed IPO valuation another substantial step up.

The UK retail route relies on the public offer platform (POP) regime introduced on January 19, 2026, which allows eligible securities offerings through authorised platforms without the conventional UK prospectus route. This is evidence of cross-border distribution, not a relocation of Anthropic’s listing to London.

What’s Next

The decisive next disclosures are the price range, shares offered, primary-versus-secondary split, final timetable and participating UK platforms. Until those appear, the headline should be read as a reported distribution plan—not a completed offer or guaranteed retail allocation. Anthropic did not respond to a request for comment.

Correction: An earlier version of this article misstated the date of the amended filing. It was November 2, not November 1.
