ChatGPT maker OpenAI filed preliminary paperwork that would open the door to it becoming a publicly traded company, a move that follows rival Anthropic and Elon Musk's SpaceX also aiming to become publicly traded companies.

The ChatGPT maker announced it has filed paperwork to go public, just a week after rival Anthropic took the same step.

The ChatGPT maker’s move follows rival Anthropic’s filing and comes days before SpaceX’s expected $1 trillion-plus debut on the stock market.

OpenAI files confidential IPO paperwork with SEC, opening door to potential listing as AI race heats up with rivals like Anthropic and SpaceX.
