OpenAI files for IPO, following Anthropic

The Verge reports that OpenAI announced on Monday that it has confidentially submitted a Form S-1 to the U.S. Securities and Exchange Commission, an initial step as the company moves toward a potential initial public offering, or IPO. The article frames the move within the context of the IPO race between OpenAI and Anthropic over the past year, noting in particular that Anthropic had already taken the same step on June 1. OpenAI’s filing can therefore be seen as following its rival’s capital markets strategy. According to the information provided in the original article, the filing was “confidentially submitted,” meaning the public currently cannot view complete financial data, risk disclosures, fundraising size, valuation range, or a planned listing timetable in a public prospectus. For AI industry observers, the key point is not that OpenAI has already officially listed, but that it has entered a preparatory stage that could lead to a public listing, while its main competitor Anthropic has also begun a similar process. This reflects the enormous funding support large AI companies need for model training, computing power, talent, and commercialization, with capital markets potentially becoming an important battleground in the next phase of competition. However, the original article did not provide further transaction details and did not state whether the IPO will definitely be completed. This news should therefore be interpreted as an important but still early business signal, rather than a conclusion that OpenAI is certain to go public.
