Anthropic has filed preliminary paperwork to sell stock to the public — a move that could put it among the most valuable companies ever to debut on U.S. markets.
NPR reported the filing Sunday, June 1. Anthropic’s IPO, alongside a potential public offering from OpenAI, could rank among the biggest in U.S. history, according to NPR’s reporting. Neither company has yet set a price or confirmed a timeline.
The filings come as investor appetite for artificial intelligence companies has grown sharply. Anthropic — backed by billions in funding from Amazon and Google — makes the Claude family of AI models and has positioned itself as a safety-focused rival to OpenAI. Whether that reputation commands a premium valuation from public investors won’t be known until the offering prices.
IPO paperwork filed at the preliminary stage doesn’t lock in a date or a share price. Companies routinely amend such filings — sometimes multiple times — before a deal actually goes to market. Anthropic hasn’t said when it expects the process to conclude.
OpenAI, for its part, hasn’t filed comparable paperwork publicly, though NPR grouped the two firms together as potential market-shaking debuts. The exact order and scale of either offering remains unresolved.
