OpenAI quietly submitted a confidential registration statement for an initial public offering with the SEC, following Anthropic's confidential S-1 submission by one week. Wedbush analyst Dan Ives described the near-simultaneous filings as a pivotal moment for the IPO pipeline in artificial intelligence, suggesting the move could open broader access to AI companies seeking public capital.
In a note to clients, Ives framed the sequence of filings as a structural change to how investors will approach AI listings. "The floodgates for the IPO market are officially open with three major AI conglomerates set to go public later this year, but the race is starting to move faster as both Anthropic and OpenAI are expected to file their S-1s over the coming weeks that investors will be eagerly waiting for," he wrote.
Wedbush points to a sharply expanded financial profile at OpenAI as context for the confidential registration. The firm reports OpenAI is producing roughly $2 billion in revenue each month, which equates to about $24 billion in annualized recurring revenue. That revenue trajectory underpinned a March 2026 financing where OpenAI secured $122 billion in committed capital and saw its valuation rise to $865 billion from a previous $500 billion level set during an employee tender and share sale.
Beyond the headline valuation and fundraising totals, Wedbush emphasizes that the S-1 will reveal substantive financial detail for the first time. The registration will disclose OpenAI's revenue mix, cost structure, margins and cash consumption related to compute and infrastructure buildout, areas that market participants have long speculated about but which have not been publicly detailed.
Despite submitting the confidential S-1, OpenAI has signaled that a public offering could be some time away. Company commentary accompanying the filing noted it "may be a while" before the firm actually lists, adding that there are initiatives the company believes are "likely easier as a private company." While a public listing had been discussed as possibly occurring as early as the fourth quarter, Wedbush stresses that no fixed timeline has been announced.
Competitive dynamics are a central element in the strategic calculus described by Wedbush. Ives wrote that "Altman continues to face competitive pressures from competitors like Anthropic to show that growth continues to accelerate and will maintain its current aggressive pace through the next decade." The closely timed confidential filings from the two leading labs illustrate how the companies are tracking each other's moves and how competitive pressure may be accelerating their paths to public markets.
Adding to the public-market narrative, OpenAI released GPT-5.5 concurrently with the filing. Wedbush characterizes GPT-5.5 as OpenAI's most capable model to date. According to the firm, the model achieves an 82.7% accuracy rate for complex command-line workflows that require planning, iteration and tool coordination, and it reaches a 58.6% success rate when solving tasks end-to-end in a single pass. Wedbush also reports that GPT-5.5 matches the per-token latency of GPT-4.5 while operating at a higher intelligence level, which the firm interprets as a more efficient use of model tokens.
For investors and market watchers, the immediate catalyst remains the formal S-1 filing becoming public. When OpenAI officially registers its offering, the filing will, for the first time, lay out explicit numbers on the company's cost base, burn rate and the trajectory for profitability. Those margin and cost disclosures will be critical in evaluating how the company’s eye-catching revenue figures translate to sustainable earnings and how investors price the IPO.
What this means for markets
- Public disclosure of OpenAI's S-1 will provide a clearer picture of revenue, margins and capital intensity for a major AI operator.
- Back-to-back confidential filings from top AI labs suggest heightened competition and a faster timetable for several AI companies considering public listings.
- The launch of GPT-5.5 reinforces OpenAI's product and performance story that it will present to prospective public market investors.
