TL;DR — Key Takeaways
-
OpenAI Revenue Falls Short of Estimates: OpenAI’s annualized revenue approached $50 billion at the end of September, roughly $20 billion below estimates based on earlier investor calculations.
-
Accounting Differences Drive Discrepancy: Different methods of counting revenue generated through third-party cloud providers contributed to the gap between OpenAI’s reported figures and investor estimates.
-
AI Stocks Face Selling Pressure: The revenue discrepancy fueled concerns about AI demand, contributing to declines in the Nasdaq Composite and shares of NVIDIA, Oracle and Micron.
Questions over the meteoric growth rate of artificial intelligence (AI) demand spilled into global financial markets this week after a report that OpenAI’s annual revenue is roughly $20 billion lower than previously communicated to investors.
Investor documents reviewed by the Financial Times show that the ChatGPT creator reached an annualized revenue approaching $50 billion at the end of September. While representing substantial year-over-year expansion, the figure falls far short of the $70 billion baseline widely reported in prior investor disclosures.
The lower revenue baseline rattled technology stocks, triggering a 1.4% decline in the Nasdaq Composite. Key semiconductor and cloud infrastructure providers felt the brunt of the selloff. Shares of NVIDIA Corp. dipped 3%, Oracle Corp. tumbled 5.5%, and Micron Technology Inc. fell 4.8%.
The revenue discrepancy stemmed from accounting adjustments made by investors attempting to draw direct comparisons between OpenAI and its primary competitor, Anthropic, according to sources familiar with the matter.
Anthropic includes revenue generated through third-party cloud service providers, such as Amazon Web Services and Google Cloud, whereas OpenAI excludes partner-channel sales from its internal annualized run-rate figures.
When investors attempted to standardize the metrics — adjusting July baseline figures and applying OpenAI’s reported 70% growth rate — they arrived at the inflated $70 billion estimate for September, a figure OpenAI did not initially publicly clarify.
While Bloomberg reported that OpenAI still aims to reach or exceed $70 billion by year-end, the revised September figure has intensified scrutiny over the commercial economics underpinning the generative AI boom.
The financial recalibration comes at a delicate moment for OpenAI, which is currently in early-stage talks to raise $30 billion in a funding round that would value the enterprise at approximately $1.4 trillion. The company previously closed a $122 billion round at an $852 billion valuation, while Anthropic raised $65 billion to reach a $965 billion valuation.
Despite massive fundraising capacity, analysts warn that lower-than-anticipated revenue rates could strain capital budgets. OpenAI is projected to burn nearly $280 billion in cash by 2030 to finance computing power and infrastructure needs, placing significant pressure on its ability to generate recurring top-line revenue.
Meanwhile, broader structural headwinds and regulatory concerns continue to shift execution timelines across the sector. OpenAI CEO Sam Altman recently confirmed the company has paused plans for a public market listing this year, citing safety concerns surrounding increasingly autonomous AI agents. Conversely, rival Anthropic is expected to proceed with an initial public offering as early as next month.
At the same time, technical experts question whether scaling larger frontier models will continue to yield proportional economic returns.
Industry observers note that as open-source and on-device models become “good enough” for everyday tasks, corporate advantage may shift away from standalone model developers toward platform incumbents like Alphabet, which can run lower-cost AI operations directly across integrated software ecosystems.
Capital continues to flood into the broader ecosystem despite market volatility. SoftBank Group founder Masayoshi Son is currently seeking up to $100 billion from Gulf sovereign wealth funds to deepen AI investments, following SoftBank’s own $65 billion commitment to OpenAI and a record $11.1 billion high-yield corporate bond offering last month.
