Multiple outlets report that Anthropic, the AI company behind Claude, confidentially files draft registration paperwork with the U.S. Securities and Exchange Commission (SEC) to pursue an initial public offering (IPO). The filings mark a key milestone in a reported race between Anthropic and OpenAI to reach public markets first. Coverage notes that the company’s submission gives it the option to move forward after the SEC completes its review, and that terms such as the number of shares and pricing are not yet set.

Separate reporting indicates OpenAI also files confidentially for a U.S. IPO shortly after Anthropic, further escalating competition between the two AI firms. Some accounts describe the potential IPO as among the largest the market has seen, while others connect the timing to recent high-profile tech listings. There is also mention that Anthropic and OpenAI are targeting public-market debuts that could occur as early as later this year, though no confirmed date or valuation is provided in the excerpts. Overall, the filings initiate SEC review and set the stage for possible large-scale fundraising and valuation tests for the broader AI IPO market.
