Coinbase announced that eligible U.S. retail investors can now apply for initial public offering (IPO) stock allocations directly through its app, with Oura's IPO this week being the first project. Users can apply for shares at the offering price before public trading begins, but allocations may be fully, partially, or completely denied. Investors who sell shares within 30 days after the IPO may be prohibited from participating in subsequent IPOs. The service is provided by FINRA-registered broker-dealer Coinbase Capital Markets, with trade execution, clearing, and custody handled by Apex Clearing Corporation.
