Anthropic Files Confidential SEC Paperwork For Proposed Stock Offering
Anthropic confidentially submitted a draft Form S-1 to the Securities and Exchange Commission on Monday, June 1, 2026, seeking approval for a proposed initial public offering.[1]
Anthropic said the IPO timing will depend on SEC review, market conditions and other factors, and it has not set a share count or price range.[1] Wedbush Securities analysts said the move, plus possible listings from SpaceX and OpenAI, could help reopen the U.S. IPO market.
A recent fundraising round valued Anthropic at roughly $965 billion. That figure eclipsed OpenAI's reported $852 billion valuation in March 2026. The high valuation and fresh capital have made a public listing a plausible next step for the company.
Because the filing was confidential, details will be disclosed only after SEC review and any public S-1 is filed. If Anthropic proceeds, its IPO would be among the most closely watched technology offerings given the company's size and the broader interest in AI stocks.
