OpenAI Files for IPO at $852 Billion Valuation
OpenAI filed a confidential S-1 registration statement with the Securities and Exchange Commission on June 8, 2026, at an $852 billion valuation based on its March 2026 funding round. Goldman Sachs and Morgan Stanley are serving as underwriters for what would be one of the largest tech IPOs in history. The company has not announced a firm IPO date and emphasized that the filing should not be interpreted as an imminent listing.
Company Maintains Flexibility on Timing
OpenAI stated that it "has not decided on timing yet" and may remain private for an extended period while retaining the option to list sooner if market conditions are favorable. Reports suggest a potential September 2026 debut, but the company has not confirmed this timeline. The filing follows Anthropic's June 1 confidential S-1 submission, creating the potential for competing AI lab IPOs.
March 2026 Funding Round Establishes Valuation
The $852 billion valuation stems from OpenAI's March 2026 funding round, which included major investors:
- Amazon
- Nvidia
- SoftBank
- Additional undisclosed investors
This valuation would make OpenAI one of the most valuable private companies ever to go public. The filing comes after OpenAI's May 2026 jury win cleared the company's Public Benefit Corporation restructuring, removing a significant legal obstacle to public listing.
Revenue Projections Face Industry Scrutiny
The IPO filing arrives amid broader questions about AI economics and sustainability. OpenAI and Anthropic reportedly need $174-184 billion in combined annual revenue by 2029 to justify current valuations and infrastructure investments. However, current projections suggest OpenAI will reach approximately $60 billion in revenue for 2026. The AI industry has committed $9.5-15 trillion to data center infrastructure, raising concerns about the gap between investment and revenue generation.
ChatGPT has reached approximately 900 million weekly users according to some reports, demonstrating significant user adoption even as questions persist about monetization at scale.
