OpenAI — Business Customers: 1 million

NoteThe source directly confirms the claim. The exact stored value in the claim (1,000,000) matches the source's statement of 'more than 1 million business customers.' The announcement date in the source is November 5, 2025, which falls within the claimed timeframe of 'as of 2025-09' (September 2025). The source also confirms the additional context that this is 'the fastest-growing business platform in history.' The slight temporal discrepancy (November vs. September) is minor and the source's November announcement would reflect the milestone achieved by that point, consistent with the claim's September reference.
