OpenAI has confidentially filed for an IPO with the SEC, potentially marking one of the largest public market debuts alongside SpaceX and Anthropic.

OpenAI said it has not decided exactly when the IPO would take place.

OpenAI's confidential filing lands days before SpaceX is set to go public and a week after Anthropic announced its confidential disclosure with the SEC.

The moves comes days ahead of SpaceX's IPO.
