OpenAI at $25 Billion: The Most Anticipated IPO in Tech History Is Getting Closer

Published: April 29, 2026

There was a time, not long ago, when OpenAI was a scrappy non-profit research lab that most people outside AI circles had never heard of. That was 2022. In less than four years, the company behind ChatGPT has grown into one of the most valuable private businesses in human history — surpassing $25 billion in annualized revenue as of February 2026, closing a $122 billion funding round (the largest private financing in history), and laying the groundwork for an IPO that Wall Street is describing as potentially the biggest public listing since Alibaba.

The story of OpenAI’s ascent is remarkable on its own. But it also raises serious questions about sustainability, competition, and what it actually means to build a profitable business in the age of AI.

The Numbers Are Staggering

Let’s start with the revenue figures, because they are genuinely hard to comprehend.

OpenAI generated $2 billion per month as of early 2026. Annualized, that’s $25 billion — up from roughly $20 billion at the end of 2025, $6 billion in 2024, and just $2 billion in 2023. In other words, the company more than tripled its revenue in a single year, and has been growing revenue approximately 3-4x year-over-year for multiple years running.

For context: OpenAI is, according to its own announcement, growing revenue four times faster than Alphabet and Meta did at comparable stages. ChatGPT has surpassed 900 million weekly active users and 50 million paying subscribers. The enterprise side of the business now makes up more than 40% of total revenue, with the company targeting parity between enterprise and consumer revenue by end of 2026.

In February 2026, OpenAI closed the largest private funding round in history — $122 billion at a post-money valuation of $852 billion. The investor lineup reads like a who’s-who of the most powerful institutions in the world: Amazon committed $50 billion (with $35 billion contingent on an IPO or AGI milestone by December 2028), NVIDIA invested $30 billion, and SoftBank contributed $30 billion in structured tranches.

The IPO Question

OpenAI has not officially confirmed an IPO date. But the signals are increasingly clear: a filing in the second half of 2026 and a public listing in 2027 appears to be the working plan, with the company potentially valued at up to $1 trillion at debut.

The company has hired Cynthia Gaylor, former CFO of DocuSign, as its first-ever Head of Investor Relations — a position that exists entirely to sharpen messaging and governance ahead of a public listing. The corporate structure has been undergoing a significant transformation, converting from a capped-profit model to a more traditional for-profit entity.

One wildly unusual fact worth noting: Sam Altman, OpenAI’s CEO, currently holds zero equity in the company. His equity line in internal documents reportedly shows “TBD.” Whether he receives a significant stake before the IPO is one of the most-watched governance questions in Silicon Valley.

Amazon’s $35 billion commitment is also tied to a specific clause: the funds are contingent on an IPO or an AGI (Artificial General Intelligence) milestone by December 2028. That creates a structural incentive for OpenAI to go public within the next two-plus years.

But There’s a Catch: The Company Is Losing Billions

Here’s the part of the story that gets less attention in the breathless coverage: despite $25 billion in annualized revenue, OpenAI is currently losing approximately $14 billion per year. Breakeven is projected for around 2030. By 2027, the annual cash burn rate could reach $57 billion.

The losses are almost entirely a function of compute costs — the enormous expense of training and running frontier AI models requires vast amounts of GPU processing power, which costs extraordinary amounts of money. The company has committed to over $500 billion in cloud infrastructure spending across multiple providers including Microsoft Azure, Amazon AWS, and Oracle.

This is a familiar pattern in technology — spend aggressively now to build scale, achieve profitability later. Amazon did it. Netflix did it. Tesla did it. The bet is that as AI models become more efficient and as revenue continues to scale, the economics will eventually invert in OpenAI’s favor.

But the math requires things to keep going right. Revenue must continue growing. Enterprise adoption must scale. Compute costs must decrease through improved efficiency. None of these are guaranteed.

The Competition Is Catching Up Fast

Another narrative running beneath the IPO story is the competitive threat from Anthropic, the company behind Claude.

Anthropic has surged to approximately $19 billion in annualized revenue — roughly 14 times higher than just a year earlier. The gap between OpenAI ($25 billion) and Anthropic ($19 billion) has compressed to just $6 billion. More concerning for OpenAI is the trajectory: Anthropic’s revenue has been growing at approximately 10x per year versus OpenAI’s 3-4x. Some analysts project Anthropic could surpass OpenAI in annualized revenue by mid-2026.

In the enterprise API market — arguably the most valuable battleground — OpenAI’s market share has fallen from 50% in 2023 to around 25% by mid-2025, while Anthropic has climbed from 12% to 32% over the same period.

Google’s Gemini, Meta’s Llama, and a growing ecosystem of open-source models are also competing for the same market. The question of whether AI foundation models will eventually commoditize — becoming infrastructure rather than differentiated products — is existential for OpenAI’s valuation.

What OpenAI Is Betting On

The company’s strategic answer to these challenges is the “superapp” — a unified platform that merges ChatGPT, Codex, an Atlas browser, and broader agentic capabilities into a single AI-first operating experience. The vision is ambitious: rather than competing on individual model benchmarks, OpenAI wants to control the interface through which people interact with AI, making it as indispensable as Google Search was for the previous era of the internet.

The company’s flywheel is simple in theory: more compute enables more capable models, better models drive better products, better products drive more revenue, more revenue funds more compute. The question is whether OpenAI can maintain its lead long enough for the flywheel to spin at scale — and whether an IPO can provide the additional capital to keep building.

Should Retail Investors Be Excited?

History has a cautionary tale here. The 10 largest IPO stocks in recent decades dropped by a median of 11% in their first three months of trading, and 26% in their first year. Companies going public at very high valuations have a particularly mixed record of outperforming the broader market over time.

OpenAI at $1 trillion would be the largest IPO in US history. Buying at that valuation means betting the company’s most explosive growth is still ahead of it — that the path from $25 billion to the $280 billion revenue target by 2030 is achievable. That’s a bold bet even for the most bullish AI investor.

That said, OpenAI is not a typical company. ChatGPT is arguably the most widely used consumer AI product in history. The brand recognition, user base, and enterprise relationships are genuinely remarkable. For investors willing to accept the risk of a high-multiple, pre-profitability technology company, the IPO — whenever it arrives — will be one of the most closely watched listings of the decade.
