Micron, Nvidia Shares Fall as OpenAI's $50 Billion Revenue Run Rate Misses Estimates
Key Takeaways
- •OpenAI's annualized revenue run rate stood at approximately $50 billion as of the end of September, well short of prior estimates in the $68–70 billion range.
- •Nvidia shares fell about 3%, Oracle dropped roughly 5–6%, AMD, Broadcom, and Intel each declined 4–5%, and the Nasdaq Composite lost approximately 1.25% following the disclosure.
- •The gap between OpenAI's run rate and earlier expectations was attributed to differing revenue accounting methods between OpenAI and Anthropic, both privately held companies not bound by standardized disclosure rules.
- •Despite the shortfall versus expectations, OpenAI's overall third-quarter run rate grew 77%, with its enterprise segment posting 107% run-rate growth.
- •OpenAI is reportedly in discussions over large funding rounds and is considering a potential IPO in 2027, which would place its financial reporting under public-market disclosure requirements.

Shares of Nvidia, Micron Technology, and other AI-linked companies slid on Wednesday, October 8, 2026, after OpenAI's annualized revenue run rate — a projection that extends recent revenue to a full-year figure — came in at approximately $50 billion as of the end of September. The figure landed well short of prior estimates in the $68–70 billion range.
Broad Declines Across the AI Trade
The selloff spread quickly. Nvidia shares dropped around 3%, while Oracle fell by roughly 5% to 6%. Other chipmakers were also hit, with AMD, Broadcom, and Intel each seeing declines in the 4% to 5% range.
The broader market felt the pressure as well. The Nasdaq Composite fell approximately 1.25% on the day.
Accounting Differences Behind the Miss
The gap between the roughly $50 billion run rate and earlier estimates was attributed to differences in how OpenAI and rival Anthropic account for revenue. Comparing the two companies side by side had apparently inflated expectations for OpenAI, rather than signaling that its business had stalled.
As privately held companies, neither OpenAI nor Anthropic reports financials under the standardized disclosure rules that apply to public companies, so run-rate comparisons between them rest on figures each discloses on its own terms. Despite the shortfall versus expectations, OpenAI's overall third-quarter run rate grew 77%. Its enterprise segment performed even better, posting run-rate growth of 107%.
Micron's Awkward Position
Micron's slide stands out because its own fundamentals have been tied directly to AI demand. The company reported record gross margins of 84.9% in one quarter, driven by demand for high-bandwidth memory — the memory placed alongside AI processors in data centers — and DRAM used in AI applications. That direct exposure to AI hardware spending helps explain why the stock moved with the broader AI trade on the disclosure.
A Volatile Year for AI Stocks
The AI infrastructure market is already under heightened scrutiny because of high valuations and rising interest rates. OpenAI itself is reportedly in discussions over large funding rounds and is considering a potential IPO in 2027 — a step that, if completed, would place its financial reporting under public-market disclosure requirements.
A Concentrated Trade
The October 8 selloff shows how concentrated the AI trade has become. A single revenue disclosure from one private company was enough to move Nvidia, Oracle, AMD, Broadcom, Intel, Micron, and the Nasdaq in the same direction on the same day.
The accounting angle also deserves attention. If OpenAI and Anthropic measure revenue differently, investors comparing the two have been working with mismatched figures.
