OpenAI readies new AI model, files for IPO after $25B revenue

OpenAI is preparing a new AI model, according to an exclusive report from The Information. The upcoming model succeeds GPT-5.5 Pro and Instant, which have served as the company's frontier releases since May 2026. CEO Sam Altman reportedly told employees that the company expects to go public within the next year, though a delay to 2027 remains possible. The development comes as OpenAI has surpassed $25 billion in annualized revenue, a milestone that underscores its explosive growth since the launch of ChatGPT.

The same day the report broke, OpenAI made a confidential S-1 submission to the SEC, a preliminary step toward an initial public offering. While the exact timeline is fluid, Altman's internal messaging suggests the company is actively preparing for the transition to a publicly traded entity. The new model, still unnamed, is expected to push the boundaries of reasoning, coding, and multimodal capabilities, building on the architecture of GPT-5.5. For enterprise customers and developers, this signals continued investment in frontier AI capabilities, while the IPO move will open OpenAI to broader investor scrutiny.
