OpenAI plans to go public, intensifying investment race with Anthropic

OpenAI has revealed plans to sell shares to the public through a stock listing in the US.

The artificial intelligence (AI) company behind the popular chatbot ChatGPT said on Monday that it had made a confidential filing with the US Securities and Exchange Commission to pursue an initial public offering (IPO) at some point in the future.

"We have not decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company," the company said in a statement.

OpenAI's decision had been expected for months, but the company's filing comes exactly one week after rival AI firm Anthropic said it was planning to go public, too.

Anthropic, the company behind the chatbot Claude, said the price and number of shares to be offered "have not yet been set" but planned to make an initial public offering this year.

Both firms' stock market plans, coming alongside those of Elon Musk's SpaceX and Grok, is set to show whether investor appetite matches the soaring valuations of AI companies.
