OpenAI will not go public until it can “make confident safety decisions,” according to chief executive Sam Altman, as the company faces a new lawsuit over its tools hacking a third party.

Altman said it was “bad for the world if OpenAI waits too long to go public” but that the $852 billion start-up would not “barrel all guns blazing towards an IPO” at a time when AI was rapidly advancing in capabilities.

On Tuesday, a non-profit legal organization called Legal Advocates for Safe Science & Technology (LASST) filed a lawsuit in California seeking to ensure OpenAI takes a more robust approach to AI development.

Having already pushed its IPO to next year, OpenAI is in talks with investors about a new private funding round. The company is seeking to raise 1.4 trillion.

OpenAI’s annualized revenue has grown more than 70 percent since July, when it released GPT-5.6, and is now about $70 billion.
