OpenAI Files Confidential S-1 for IPO, But CEO Altman Says Listing May Be Delayed

ChatGPT developer takes formal step toward public offering while outlining a post-AGI economic vision, but warns that a near-term market debut is unlikely.

OpenAI, the developer behind ChatGPT, has submitted a confidential S-1 registration statement to the Securities and Exchange Commission, marking a formal step toward a potential initial public offering. The company acknowledged the filing in a statement Monday, noting that it expects the news to become public and is proactively disclosing it. However, the firm cautioned that no listing date has been set and that a market debut may not be imminent.

“We have not decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company,” OpenAI said. The confidential S-1 allows the SEC to begin its review without requiring OpenAI to disclose its financials publicly, a common practice for high-profile private firms.

The filing comes as OpenAI navigates a complex transition from its original nonprofit-controlled structure to a more conventional for-profit model. This conversion has attracted legal challenges and regulatory scrutiny, and the company’s acknowledgment that certain moves are easier to execute privately suggests the process remains unresolved. The development adds to a wave of anticipated tech IPOs, including SpaceX and Anthropic, which are also weighing public listings.

Alongside the S-1, CEO Sam Altman and chief scientist Jakub Pachocki published a lengthy essay titled “Built to benefit everyone: our plan,” which serves as both a manifesto and an implicit investor pitch. The document draws a historical parallel to rural electrification in the 1920s, framing AI as a transformative force. It outlines three near-term goals: building an automated AI researcher to accelerate internal scientific work, using AI to drive broad economic growth while distributing gains widely, and providing every person on Earth with a personal AGI.

By the numbers
2028
target year for AI research milestone
$65B
Anthropic's recent funding round valuation
18.4%
US firms expected to use AI by 2026
$75B
SpaceX's record IPO valuation

On the research timeline, Altman and Pachocki stated: “Our internal belief is that by March of 2028 we may have a significant fraction of our research being done by AI systems in tandem with our own researchers.” The essay also addresses risks, following a recent call by rival Anthropic—which filed its own confidential S-1 after a $65 billion funding round—for the industry to consider slowing development. “Entirely automating everything is not the future we want,” the OpenAI executives wrote. “It would be unfulfilling, and it would be dangerous.”

The essay argues that as AI systems grow more capable, human judgment becomes more important, with people responsible for setting direction and applying values. Altman and Pachocki also rejected the notion of a monopoly, stating: “A good AI future cannot be one where a small number of institutions control most of the capability and most of the upside.” They called for an international body to coordinate frontier AI development and, where necessary, slow it down.

For financial advisors, the OpenAI IPO represents a potential new asset class, but the uncertain timeline and the firm’s complex governance structure warrant caution. The broader trend of AI-related IPOs—including SpaceX’s record $75 billion valuation and Anthropic’s near-$1 trillion target—could reshape portfolio allocations, though adoption remains limited, with only 18.4% of U.S. firms expected to use AI by 2026.
