The next phase of the AI race is on.With OpenAI's Monday confidential S-1 filing following in the footsteps of Antrhopic's, the two premiere AI labs are now officially in the IPO race. SpaceX, which includes Elon Musk's xAI, has a head start, and goes public later this week.While OpenAI left the door open on its timing, warning that "it may be a while" before it actually publicly lists its shares, the AI labs are moving from an era of closed-door tinkering as a private companies into the world of public earnings calls, financial disclosures, and the regulation that comes with being a publicly traded company.Is it a telling signal of just how much cash they're all burning? A chance to reward loyal employees who hold shares and help retain key AI talent?
