You can’t buy directly from Anthropic. Instead, retail shares flow through brokers, and each country has its own route.
In the US, JPMorgan is leading the domestic retail marketing and deciding share allocations. Brokers collect requests from their customers and pass that demand to the company and its banks. Robinhood’s chief financial officer, Shiv Verma, called the race between brokers for a bigger slice “a food fight.” In the SpaceX listing in June, platforms such as Fidelity, Charles Schwab, SoFi, E*Trade and Robinhood all competed for allotments, and every eligible customer who asked through them got some stock. Anthropic hasn’t said which US apps will offer its shares, so check whether your own broker has an IPO request page.
In the UK, Anthropic is reportedly working with RetailBook, a licensed operator under the country’s public offer platform rules. That lets a foreign company sell to British savers without a full UK prospectus, and other investing apps would feed orders into RetailBook. SpaceX used the same route in June and sold $364 million of stock to UK individuals. No final decision has been announced, so treat this as the expected plan rather than a promise.
In Canada, Citigroup is coordinating the international retail offer, which covers Canada along with the UK, parts of Europe, Japan and Australia. Anthropic’s IPO page has gone live with separate paths for the US, the UK, Canada, Australia and Japan, though for now it only says more information is coming. Interactive Brokers, Revolut and SBI are among the firms named as taking part.
If you miss the IPO allocation, there is a simpler option: once ANT opens on November 19, anyone with a brokerage account that trades US stocks can buy at whatever the market price is. That price may be far above, or below, the IPO price. This isn’t financial advice, just how the process works.
