OpenAI, the maker of ChatGPT, submitted a confidential draft registration statement to the U.S. Securities and Exchange Commission on Monday for a proposed initial public offering. The move, announced in a blog post, comes just over a week after chief rival Anthropic also filed to go public, intensifying the public-market showdown between the two leading artificial intelligence companies. OpenAI, most recently valued at $852 billion post-money, did not disclose details about share count, target price, or expected listing date, but acknowledged the leak-driven announcement by saying it had "not decided on timing yet" and that being private "may be easier" for certain strategic moves it wants to make. The filing lands against a strikingly different regulatory backdrop than what previous tech IPOs faced. In a separate blog post published the same day, OpenAI laid out a sweeping statement on its mission, its vision for artificial general intelligence, and its belief that AI should benefit all of humanity — the kind of forward-looking communication that companies in a traditional quiet period have historically avoided. The contrast reflects a Securities and Exchange Commission that, under the Trump administration, has taken a notably hands-off posture toward technology and AI companies compared to prior years, giving firms more latitude to communicate openly with the public. OpenAI is racing toward the public markets even as operational and financial pressures mount. The Wall Street Journal reported that the company recently fell short of its own targets for new user growth and revenue, while Chief Financial Officer Sarah Friar has reportedly raised internal concerns about whether OpenAI can sustain the cost of its massive data center expansion. That burn rate is staggering: in late March, OpenAI closed $122 billion in funding — the largest private round in Silicon Valley history — including roughly $3 billion sourced directly from retail investors through banking channels. If OpenAI, Anthropic, and Elon Musk's SpaceX all complete their public-market debuts within months of one another, 2026 would deliver a concentration of marquee tech listings not seen since the dot-com era. SpaceX is expected to price at a $1.75 trillion valuation, which would make it the most highly valued company ever to enter the public markets. Together, the three offerings would test whether investor appetite for high-growth, capital-intensive AI and space companies can absorb tens of billions of dollars in new equity at once — a question that will likely shape pricing, volatility, and deal terms across the entire IPO calendar for the rest of the year.
