OpenAI Files Confidential IPO Registration Following Anthropic Move
OpenAI submits confidential IPO registration following Anthropic’s latest funding and expansion moves in the AI industry.
Jersey City, N.J., June 9, 2026: OpenAI has submitted a confidential draft registration statement on Form S-1 to the U.S. Securities and Exchange Commission (SEC), becoming the second major generative AI company in a week to take formal steps toward a potential public offering.
The company confirmed the filing on June 8 in a statement published on its website. OpenAI did not disclose the number of shares it may offer, a potential valuation, or a timeline for a public listing. The filing follows a similar move by Anthropic, which confidentially filed for an IPO on June 1. According to OpenAI, any offering remains subject to SEC review and market conditions.
The timing places OpenAI and Anthropic on parallel paths toward public markets as both companies compete for enterprise customers and invest heavily in AI infrastructure. Anthropic’s filing marked the first IPO step by a leading generative AI developer, while OpenAI remains the company behind ChatGPT.
According to a Reuters report, OpenAI completed its transition to a public benefit corporation in late 2025. The restructuring was designed to allow the company to raise additional capital while maintaining oversight from its nonprofit foundation.
The confidential filing means investors will need to wait for a public S-1 registration statement to see detailed financial information. Reuters reported that OpenAI generated approximately $2 billion in monthly revenue as of March 2026. A future filing could provide more detail on revenue sources, operating costs, and investment priorities.
The filing comes as many businesses are using AI tools across software development, customer support, research, content creation, and workflow automation. At the same time, AI developers continue to spend heavily on computing infrastructure needed to train and operate advanced models.
For business leaders, future public disclosures could provide greater visibility into how major AI vendors generate revenue, manage infrastructure costs, and fund long-term growth. That information may help enterprise buyers evaluate technology partners as AI becomes a larger part of operational and technology budgets.
The filings by OpenAI and Anthropic highlight how competition in the AI sector is increasingly tied to access to capital as well as product development. For enterprise decision-makers, the move toward public markets could offer a clearer view into the financial and operational foundations of companies supplying AI tools to businesses worldwide.
