# Anthropic confidentially files IPO prospectus with SEC

Anthropic said it confidentially filed its IPO prospectus with the Securities and Exchange Commission, setting up a potentially historic share sale for investors ready to jump into AI. 

"This gives us the option to go public after the SEC completes its review," Anthropic said in a statement on Monday. "The proposed initial public offering will depend on market conditions and other factors."

With its announcement, Anthropic is getting out ahead of rival OpenAI, which is readying its own confidential filing. Elon Musk's SpaceX has officially filed its prospectus and is gearing up for a roadshow this week, with plans to debut next week.
