OpenAI’s Revenue Is Reportedly $20 Billion Lower Than Thought. Nvidia Just Lost $170 Billion
A $20 billion accounting gap in OpenAI’s revenue figures sent shockwaves through chip stocks on October 8, wiping out billions in market value across Nvidia, CoreWeave, Oracle, and others. The twist is that no sales were actually lost.

On October 8, 2026, Nvidia (NASDAQ:NVDA | NVDA Price Prediction) fell 2.94% to $230.48. The drop erased roughly $169 billion of market value. It followed a report that OpenAI, a private company that releases no financial statements, told investors its annualized revenue was approaching $50 billion at the end of September.
A figure nearing $70 billion had circulated a week earlier, but OpenAI never releases that number itself. The $20 billion gap comes from how it counts revenue. OpenAI declined to comment.
Other suppliers fell further. CoreWeave (NASDAQ:CRWV) dropped 7.77%, Oracle (NYSE:ORCL) lost 5.48%, Broadcom (NASDAQ:AVGO) fell 4.35%, and AMD (NASDAQ:AMD) declined 3.90%. A gauge of chip stocks sank 3.4%, while the S&P 500 lost only 0.47%.
How a $20 Billion Gap Appeared With No Lost Sales
The higher figure came from OpenAI’s own investors, who were trying to compare it directly with Anthropic. Anthropic counts sales made through its cloud partners, and OpenAI does not.
Say a business pays for an AI model through a cloud provider’s marketplace. A company that books those partner sales reports the full amount, and a company that leaves them out reports less. That means the same demand can produce reported totals that differ by billions of dollars.
One unnamed source described an investor presentation that showed 77% total run rate growth in OpenAI’s third quarter. Nobody has confirmed that figure, but growth at that pace would mean the business is still expanding quickly.
Ranking of the Losses Shows Who Depends Most on a Few Buyers
CoreWeave fell hardest because its value rests on a $104 billion backlog funded largely with debt. Second-quarter interest expense reached $640 million.
Oracle holds $664 billion in remaining performance obligations, which is revenue under contract that it has not yet recognized. It has not disclosed how much of that comes from OpenAI.
Broadcom shipped Jalapeno, OpenAI’s first custom accelerator, and sees a path to more than 5 gigawatts of OpenAI installations in 2028. Management also said OpenAI’s financing position is less clear than that of its other big lab customer.
AMD has Meta and a 2 gigawatt Anthropic deal alongside OpenAI. OpenAI’s commitments to Nvidia total about 12 gigawatts, against $96.221 billion of revenue in Nvidia’s latest quarter.
Revenue Nobody Can Audit Supports Years of Spending
Suppliers have planned their spending assuming AI revenue keeps growing, yet a key input comes from a buyer investors cannot audit. OpenAI’s IPO has been pushed to early 2027. Until it lists, OpenAI has no audited figures and no duty to disclose them. Riding a boom like this is fine as long as you plan the exit, which is the subject of our free bubble survivor’s handbook.
Matt Maley at Miller Tabak said investors are becoming a bit skeptical about how long this huge AI spending can last. Ulrike Hoffmann-Burchardi at UBS said the firm retains strong conviction in the AI growth story.
On Nvidia, UBS has the stronger argument. Nvidia says demand runs well above the about 70% fiscal 2028 growth its supply allows.
How Nvidia’s Valuation Compares With Its Demand
The evidence supports Nvidia’s longer-term outlook. At 46 times earnings, it sells to nearly every major AI buyer, including AWS, which is deploying an additional 2 million GPUs.
Nvidia has a $5.565 trillion market value. The October 8 loss reflected questions about how one private customer counts its sales.
The next test is Nvidia’s next earnings report. If third-quarter revenue lands within the guided $108.0 billion, plus or minus 2%, the selloff was a scare over accounting. An OpenAI IPO filing with audited figures would answer the rest.
