OpenAI files for IPO as AI companies seek public listings

OpenAI filed paperwork for an initial public offering on June 9, 2026. The company said it had not decided on timing yet. The filing follows a similar move by rival Anthropic. Both companies' offerings, along with SpaceX's planned listing, are expected to rank among the largest in history.

Calls for coordinated oversight OpenAI CEO Sam Altman called for an international body to coordinate leading AI efforts and reduce catastrophic risk. He said the body should consider slowing frontier development when needed. Anthropic stated that an option to slow or temporarily pause AI research would be wise.

Its CEO and a counterpart at Google DeepMind have said this year that a slower pace would be safer but that they could not slow down unilaterally.
