OpenAI has confidentially filed for an initial public offering with the U.S. Securities and Exchange Commission, setting up a potential public market debut that could become one of the largest technology listings on record.
The ChatGPT maker confirmed that it recently submitted a confidential S-1 filing, allowing regulators to review its financial information before it becomes public. OpenAI said it has not decided on timing and may remain private for a while, but the filing gives the company the option to list sooner if that becomes the preferred path.

The company was most recently valued at $852 billion post-money. Following the filing, there is a 48% chance that OpenAI could close above $1.5 trillion in market capitalization on its first day of trading, according to Polymarket.
OpenAI Begins IPO Process With Confidential Filing
OpenAI’s confidential filing marks a formal step toward a potential Wall Street debut. The process allows the company to prepare for public listing while keeping revenue, costs, margins, and other financial details private until closer to the offering.
The company said it expected the filing to become public through leaks, so it chose to announce the submission. OpenAI added that some business priorities may be easier to handle as a private company, which means no fixed IPO date has been set.
OpenAI has been working with banks, including Goldman Sachs and Morgan Stanley, on the filing process. The company has also been preparing a tender offer that would allow employees to sell shares at its latest $852 billion valuation, offering liquidity before any public listing.
Chief Financial Officer Sarah Friar previously said it is “good hygiene” for a company of OpenAI’s size to operate with public-company discipline, though she did not provide a specific IPO timeline. The company has been viewed as a possible candidate for a listing as early as the fourth quarter of 2026, depending on market conditions and regulatory review.
ChatGPT Scale and AI Spending Face Investor Review
OpenAI became widely known after launching ChatGPT in 2022. The product now supports more than 900 million weekly active users, making it one of the largest consumer AI platforms in the world.
The company has also been expanding its enterprise business and software development tools. Codex, OpenAI’s coding assistant product, has become a major focus as the company competes with Anthropic’s Claude Code and other AI tools used by developers.
Chief Executive Officer Sam Altman said OpenAI is entering what he called its “third phase.” He described the first phase as research toward artificial general intelligence and the second phase as becoming a product company. The new phase, he said, centers on making advanced AI more abundant, affordable, safe, useful, and accessible to people and organizations.
A public listing would place OpenAI’s finances under closer market review. The company has raised more than $180 billion in funding and continues to spend heavily on compute, chips, model training, and data center infrastructure.
OpenAI has also been focusing resources internally by shutting down some smaller projects, including the short-form video app Sora, while putting more investment into enterprise products and Codex. Investors are expected to focus on revenue growth, infrastructure costs, customer retention, and the path toward stronger operating leverage.
AI IPO Race Expands With Anthropic and SpaceX
OpenAI’s filing comes one week after Anthropic confidentially filed for its own IPO. Anthropic recently closed a funding round at a $965 billion valuation, above OpenAI’s latest reported valuation of $852 billion.
SpaceX is also moving toward a public listing and has already started its investor roadshow. The company’s IPO order books are expected to close on Wednesday, with reported orders of $150 billion, representing about two times oversubscription for the listing.
Together, OpenAI, Anthropic, and SpaceX could create one of the largest IPO waves in market history. All three companies are tied to artificial intelligence either directly or through infrastructure and related technology competition.
Concurrently, traders are also watching possible OpenAI ticker symbols. In market polling cited alongside the IPO discussion, $OAI received 62% support, while $OPAI received 28%.

The IPO filing also follows the end of a legal fight between Elon Musk and OpenAI. Musk had sued OpenAI and Sam Altman, alleging they moved away from the company’s original nonprofit mission. As we reported, an advisory jury found that Musk waited too long to bring the claims, and the federal judge adopted the verdict, handing OpenAI a legal win before its IPO process advanced.
According to CoinCodex, OpenAI Pre-IPO stock forecast show a potential price target of $585.03 across the next 5 days, 1 month, and 3 months. The longer-term outlook for 2026 to 2030 remains dependent on OpenAI’s final IPO valuation, share structure, revenue growth, and investor demand.
