OpenAI has quietly crossed a milestone that puts it in rare company: $25 billion in annualized revenue, up from $3.4 billion just over a year ago. And according to multiple reports, the company is now taking early steps toward a potential initial public offering — possibly as soon as late 2026. The AI startup that launched ChatGPT barely three years ago is on track to become one of the fastest-growing companies in technology history.
The Revenue Trajectory Is Unprecedented
To put OpenAI’s revenue growth in perspective: it took Google about 8 years to hit $25 billion in annual revenue. Facebook took about 10 years. OpenAI did it in roughly 3 years from the launch of ChatGPT. The growth rate is arguably the fastest in tech history for a software company.
The revenue comes from multiple streams. ChatGPT subscriptions (Plus at $20/month and the Team and Enterprise tiers) form the consumer-facing backbone. The API business — where developers pay to use GPT-4, GPT-5, and other models in their own applications — is the enterprise growth engine. And new products like ChatGPT Enterprise and specialized AI tools for specific industries are adding incremental revenue at scale.
The IPO Conversation
OpenAI is reportedly in discussions with Goldman Sachs and Morgan Stanley about a potential IPO. The company’s board of directors has given preliminary approval for the company to go public — a significant signal that internal leadership believes the timing could be right.
The choice of late 2026 as a target reflects several factors. First, the market for AI companies is hot, and investor appetite remains strong. Second, OpenAI wants time to show continued growth and stable profitability before filing its S-1. Third, the company is waiting to see if regulatory frameworks around AI stabilize in the U.S. and Europe — a public company faces more regulatory scrutiny than a private one.
There are also internal considerations. OpenAI’s cap table is complex, with early investors (Sequoia, Thrive, Khosla Ventures) sitting alongside later investors (Microsoft, Apple, Nvidia) and employees with significant equity. An IPO would be the liquidity event that makes all that equity valuable. It would also allow the company to raise capital from public markets without giving away more equity to private investors at an increasingly high valuation.
What This Means for Competition
OpenAI’s IPO would reshape the AI landscape in ways that ripple far beyond the company itself. It would be a psychological milestone: the first pure-play AI company to go public, validating the investment thesis that generative AI isn’t just a trend but a permanent shift in how software gets built and sold.
For competitors like Anthropic, Google DeepMind, and Meta, the message is clear. The window for scaling AI infrastructure and building billion-dollar businesses is open right now. Companies that wait another 2-3 years risk being locked out of the best talent, the most advanced compute, and the narrative around AI’s future. An OpenAI IPO accelerates the AI arms race rather than slowing it.
The Bottom Line
OpenAI is not just a fast-growing AI company — it’s on track to be one of the fastest-growing software companies in history. A $25 billion annualized revenue run rate, taking on venture capital’s role as a venture capital firm itself (through its ventures fund), and now eyeing an IPO in late 2026. The trajectory is historic. The timing, if it happens, would mark the moment when AI moved from being a technology trend to being a permanent part of the public markets and the broader economy.
