NoteThe source directly confirms the claim's core assertion: OpenAI reached 1 million business customers (exact stored value: 1,000,000). The announcement date is November 5, 2025, which aligns with the claim's 'as of 2025-09' timeframe (the milestone was reached by September 2025 and announced in November).

The numeric value matches exactly (1 million = 1,000,000), and the subject (OpenAI's business customers) matches the claim perfectly.
