AI-linked stocks fell on October 8, 2026, after reports said OpenAI’s annualized revenue was about $50 billion—not the roughly $70 billion figure that had circulated in September. The gap is not evidence that OpenAI suddenly lost $20 billion in sales: Axios reported that the higher figure was a grossed-up presentation intended to make OpenAI’s revenue more comparable with Anthropic’s treatment of certain cloud-partner sales.
What the $50 billion and $70 billion figures mean
Axios reported on October 8 that OpenAI was approaching an annualized revenue pace of about $50 billion at the end of September, based on information shared with prospective investors. The roughly $70 billion figure widely reported in September was presented on a different basis. Axios said it reflected an effort to make OpenAI’s figure more directly comparable with Anthropic’s accounting for certain partner sales. These are reported private-company figures, not numbers established by a public audited annual report.

That distinction matters: the difference is a revenue-presentation and comparability issue in the reporting, not proof that sales suddenly fell by $20 billion. The Financial Times report was described by Axios and SiliconANGLE; its article text was subscriber-gated, so the available coverage does not establish an independent reading of its full account.
Why partner accounting can change the headline number
According to Axios, Anthropic counts the full customer payment for certain cloud-delivered services as top-line revenue and records the cloud provider’s share as an expense. OpenAI, by contrast, records only its share of certain partner sales. Accounting professor Francine McKenna told Axios that the difference reflects each company’s role, including control of the customer relationship and responsibility for delivery.

In practical terms, a company that reports the full customer payment can show higher revenue than one that reports only the amount it retains, even when both are involved in selling services through a cloud partner. Axios described both companies as GAAP compliant. That does not make their headline revenue figures directly comparable without understanding what each includes.
Annualized revenue is a pace, not a completed year’s sales
Annualized revenue, or a revenue run rate, takes sales from a period and projects that pace across a year. It can indicate a company’s recent scale, but it is not the same as revenue actually recognized over a completed 12-month period. Axios noted that public-market investors generally prefer actual revenue to this constructed measure.
Axios had reported on September 29 that OpenAI’s annualized run rate was almost $70 billion and had grown more than 70% since the beginning of the third quarter. SiliconANGLE said on October 8 that OpenAI’s investor presentation showed 77% annual revenue run-rate growth during the third quarter and 107% enterprise run-rate growth. Those growth figures were reported from an investor presentation; the coverage does not establish them as independently verified filings.
What happened to AI stocks on October 8
SiliconANGLE reported the Nasdaq fell 1.25% and the S&P 500 fell 0.5% on October 8, alongside declines in several AI-linked companies, including Oracle, Intel, Nvidia, CoreWeave, AMD, Broadcom, and Super Micro Computer. Kiplinger also reported declines in Nvidia, AMD, and Micron, describing the report as a factor in the tech-stock slump. These are snapshots of that trading session, not current prices, and contemporaneous coverage does not prove that the OpenAI report alone caused each move.
The investor concern described in the coverage was broader than one company’s accounting: expectations for AI growth have helped support bets on data centers, chips, cloud services, and large infrastructure spending. A lower comparable revenue figure can prompt questions about demand, valuations, and whether counterparties can meet commitments. Those are concerns investors may weigh, not evidence that AI demand has collapsed or that any specific contract is at risk.
SiliconANGLE quoted Constellation Research analyst Holger Mueller: “AI companies need massive funding and it’s still not clear how much is actually going to be required, which makes it hard to understand the real value,” he said. Mueller also said, “But in any case, there’s no room for error in the tentative calculations of investors, and so any wobbles like revenue not being what was hoped are going to create shockwaves for the wider ecosystem.”

Revenue is not profit or cash flow. Axios’s September 29 report said it had not immediately learned OpenAI’s expenses. The reported run-rate figures alone therefore do not show whether OpenAI is profitable, generating cash, or able to afford its infrastructure commitments. They also do not establish that the company’s underlying sales fell by the amount separating the two reported figures.

When comparing AI-company revenue claims, investors should check whether the figure is net of partner shares or includes them, whether it is a run rate or recognized revenue for a completed period, and what is known about expenses and cash needs. For public stocks, it is also useful to distinguish an individual company’s move from the broader market’s same-day decline.
