ChatGPT-maker OpenAI has filed to go public as the artificial intelligence heavy-hitters vie to launch the biggest initial public offering (IPO).

Widely credited with firing the starting pistol on the AI boom by launching ChatGPT in November 2022, OpenAI submitted paperwork to the US Securities and Exchange Commission for an IPO on Monday.

It comes a week on from Anthropic filing a draft submission to the commission ahead of an IPO worth a potential $1trillion.

OpenAI has not disclosed the size, terms or timeframe of the offering.

However, The Times reports it is to seek a valuation of at least $1trillion. 

An OpenAI spokesperson said it “could be a while” before any listing “because there are things we want to do that are likely easier as a private company”.
