OpenAI — Weekly Active Users: 800 million

NoteThe claim states 'OpenAI's Weekly Active Users = 800M (exact stored value: 800,000,000) (as of 2025-10)'. The source directly confirms this with a table entry showing 'October 2025: 800 million'. The exact stored value (800,000,000) matches the source's figure. The temporal specificity (October 2025) is also confirmed. The source is about ChatGPT, which is OpenAI's primary product, so the subject match is appropriate. The claim's additional context about Sam Altman and 1B+ MAU projections is not contradicted by the source, which discusses similar growth trajectories.
