OpenAI Clarifies Revenue at $50B; Arena Secures $200M; Domyn and China Advance Sovereign AI

OpenAI's annualized revenue reached approximately $50 billion in September 2026, prompting a significant correction to earlier investor estimates that had projected figures near $70 billion. The gap reflects a methodological difference in accounting for partner-channel sales rather than a business contraction; while earlier calculations incorporated gross revenue from cloud intermediaries, OpenAI's actual net share runs lower. The clarification underscores the company's continued growth—its third-quarter run-rate accelerated 77% year-over-year, with enterprise revenue climbing 107%—even as the company now projects $70 billion by year's end.
