OpenAI and Anthropic are both headed to IPOs. The confidential filing process involves SEC review before public disclosure. OpenAI was unspecific about timing, saying it may be a while as some things are easier as a private company.
The exact amount to be raised will be decided later. Appetite for AI seems bottomless despite market dip. SpaceX is also an AI company now. Google raised $85 billion for AI drive. There's a lot of money flowing in with little braking.
