OpenAI has told investors that its annualized revenue reached nearly $70 billion by the end of September, a figure that places the ChatGPT maker in revenue territory once reserved for established technology giants.

The disclosure lands as OpenAI is reportedly preparing for a potential initial public offering targeted for 2027.

What the Numbers Actually Say

The headline metric is annualized revenue, often called the run rate. It is a snapshot of the company's current pace projected forward, not revenue already booked over a full year. Run-rate figures are a common yardstick for fast-growing subscription businesses, but they sit outside the audited reporting standards that public companies are held to.

OpenAI's prior benchmark was an annualized run rate of approximately $40 billion in August. Moving from roughly $40 billion to nearly $70 billion in about two months represents growth of more than 70% since the start of the third quarter of 2026.

Business customers appear to be the primary growth driver. Enterprise revenue has more than doubled since July, signaling that corporate buyers are moving beyond pilot programs and writing larger checks.

Consumers are spending as well. Revenue from consumer products in the third quarter alone exceeded OpenAI's total consumer revenue for all of 2025. That category includes ChatGPT subscriptions, the product that made the company a household name.

Revenue Up, Profits Still Missing

Strong sales have not translated into profit. OpenAI remains unprofitable, weighed down by the heavy cost of the infrastructure and model training that power its products. That cost structure reflects the economics of frontier AI development, where computing capacity — the same kind OpenAI draws from suppliers like Oracle — ranks among the largest expenses.

The Ripple Effects

The update did not stay contained within OpenAI. Oracle, which supplies computing capacity tied to OpenAI's operations, saw its shares climb following the news, with reported gains reaching as much as 8% — a reminder of how closely AI developers and their computing suppliers are now linked in public markets.

The competitive backdrop matters as well. OpenAI is locked in a race with rival AI developers, most notably Anthropic, for both enterprise contracts and developer mindshare.

What It Means

The most important detail for investors may be the enterprise surge rather than the top-line figure. Enterprise contracts tend to be stickier, carrying longer commitments and deeper integration into business workflows.

Run-rate figures still deserve scrutiny. They capture momentum at a single point in time, and public market investors will eventually want audited, full-year revenue alongside a credible route to profitability — a bar that becomes unavoidable if the reported 2027 listing plans move ahead.

The profitability gap is the risk to watch. OpenAI's costs scale with its ambitions, and if infrastructure spending continues to outpace revenue growth, even a nearly $70 billion run rate may not be enough to close the gap anytime soon.
