OpenAI’s revenue math is giving Wall Street a headache

OpenAI Revenue Discrepancy Causes Wall Street Headache

Revenue Reporting Methodology

OpenAI has pushed back on any suggestion that business is slowing, despite a gap in revenue estimates between the company and investors. The discrepancy stems from two different ways of counting the same money: gross and net. The company reports revenue on a net basis, while investors had been using a gross methodology similar to Anthropic's.

Quarterly Growth

OpenAI announced 77% overall run-rate growth in the third quarter of 2026, with enterprise revenue growing 107% over the same stretch. The company remains optimistic about reaching or topping $70 billion in annualized revenue by year end on its own net accounting terms.

Market Impact

The gap in revenue estimates has caused a stir in the market, with Oracle shares falling 5% on October 8. Investors should be cautious when comparing companies that use different revenue methods, as the comparison is meaningless without context.

Competitive Landscape

The enterprise figures may be the most telling detail in OpenAI's update, suggesting businesses are paying up for its tools. However, the competitive landscape is complex, with Anthropic's gross approach producing larger headline numbers. This may flatter one company over another in terms of who is winning the enterprise race.

Outlook

Investors should keep an eye on how AI companies describe their revenue going forward. Until then, anyone sizing up an AI company's growth would be wise to ask a simple question first: gross or net?

Conclusion

The OpenAI revenue discrepancy highlights the importance of understanding revenue reporting methodologies. It also underscores the need for investors to be cautious when comparing companies that use different revenue methods. As the AI trade continues to evolve, it is essential to stay informed about the latest developments and trends.
