OpenAI has submitted a confidential S-1 filing to the US Securities and Exchange Commission, marking the first formal step toward an initial public offering that could value the company at over $1 trillion, according to livemint.com. The filing was announced on June 8, 2026, just one week after rival AI firm Anthropic made a similar confidential IPO filing.
The filing was disclosed in a brief blog post by OpenAI, which also cautioned that the stock market debut may still be some time away. This confidential submission follows Anthropic’s confidential S-1 filing on June 1, 2026, signaling a growing trend of AI companies preparing for public listings. OpenAI CEO Sam Altman spoke to reporters around the time of the filing, highlighting the company's cautious approach to going public.
OpenAI’s potential IPO is one of the most consequential in technology history, reflecting the rapid growth and investor interest in AI startups. The company’s valuation could surpass $1 trillion, placing it among the largest tech IPOs ever. This move follows Anthropic’s similar filing, underscoring the competitive landscape in the AI sector as firms seek to capitalize on market enthusiasm and expand their financial resources.
The confidential S-1 filing with the US Securities and Exchange Commission is a critical regulatory step, but OpenAI has indicated that the IPO may not happen immediately. The company’s next major public disclosure will likely come with the formal IPO filing, which investors and market watchers will scrutinize closely.
