OpenAI, the artificial intelligence company behind ChatGPT, has officially taken its first major step toward becoming a public company after confidentially filing its S-1 registration with the U.S. Securities and Exchange Commission (SEC). The filing marks one of the most anticipated IPOs in technology history and positions OpenAI at the center of what could become the defining AI listing cycle of the decade.

The move comes just days after rival Anthropic submitted its own confidential IPO filing, signaling that the race among leading AI companies is rapidly shifting from private capital markets to Wall Street. With Anthropic, OpenAI, and several other AI-focused companies pursuing public market listings, 2026 is emerging as a landmark year for AI investing.

OpenAI’s IPO Status and Timeline

OpenAI confirmed on June 8, 2026, that it had confidentially submitted a draft registration statement to the SEC. A confidential filing allows companies to begin the regulatory review process without immediately disclosing detailed financial information, business risks, or offering terms to the public.

At this stage, OpenAI has not announced the number of shares it intends to offer, the expected IPO price range, or the amount of capital it plans to raise. The company has also stated that no final timeline has been set, noting that some aspects of its business may be easier to execute while remaining private. However, reports suggest a public debut could occur as early as September 2026, subject to regulatory approval and market conditions.

Why OpenAI’s IPO Matters

The OpenAI IPO represents more than another high-profile technology listing. It is expected to become one of the largest and most closely watched public offerings ever attempted by an AI company and could establish a new benchmark for how investors value artificial intelligence businesses.

If successful, the IPO could:

• Create a public market valuation benchmark for frontier AI companies

• Give investors direct exposure to the generative AI industry

• Accelerate funding for advanced AI infrastructure and computing power

• Intensify competition between OpenAI, Anthropic, Google DeepMind, and other AI leaders

• Influence technology indices and institutional portfolio allocations.
A confidential filing does not guarantee that an IPO will occur. Any offering would remain subject to regulatory review, market conditions, and the company’s strategic considerations.

OpenAI’s Valuation and Share Price Expectations

OpenAI is already considered among the most valuable private companies in the world. While private market figures are subject to widespread speculation, reports suggest massive valuations:

• Estimated private valuation: up to $852 billion
• Potential IPO valuation target: approaching $1 trillion
• Monthly revenue: approximately $2 billion
• Weekly active users: more than 900 million

A valuation approaching $1 trillion would make OpenAI's offering one of the largest IPOs in market history and place it in the same league as other highly anticipated mega-listings such as SpaceX and Anthropic.

Business Growth and Market Position

OpenAI's rise has been fuelled by the explosive adoption of ChatGPT and the broader demand for generative AI tools across consumers, enterprises, developers, and governments. Since launching ChatGPT in late 2022, the company has expanded into enterprise AI solutions, developer APIs, advanced reasoning models, coding tools, AI agents, and productivity applications. The company now serves hundreds of millions of users globally and continues to attract significant backing from major technology and investment firms.

Its strategic partnerships and investments from organizations, including Microsoft, have helped fund the massive computing infrastructure required to train and deploy advanced AI models at scale. Despite its rapid growth, OpenAI remains in a heavy investment phase as it competes for leadership in the global AI race.

About OpenAI

OpenAI was founded in 2015 as an artificial intelligence research organization with a mission to develop AI systems that benefit humanity.
