OpenAI revenue run rate nears $50 billion, below prior estimates

OpenAI told investors its annualized revenue was approaching $50 billion at the end of September. That sits about $20 billion below prior widely circulated estimates near $70 billion, including a $68 billion figure in some coverage Oracle and Microsoft shares fell Thursday, October 8, 2026, after the report. The figures are run-rate estimates, not full-year booked revenue. Anthropic counts cloud-partner sales while OpenAI excludes them, complicating peer comparisons. Contested: Quartz described OpenAI as correcting the annualized revenue figure to $50 billion. Other accounts treat the gap as largely an accounting-method difference rather than a restatement of booked results. OpenAI is privately held with no public quarterly filing to resolve the discrepancy.
