OpenAI Foundation — key-event: California AG investigation into OpenAI restructuring (ongoing since ~mid-2024, concluded Oct 2025)

NoteThe source confirms the existence of a California AG investigation into OpenAI's restructuring/recapitalization and confirms the 'year and a half' duration as of October 2025. However, the claim specifies the investigation began 'circa mid-2024' and 'concluded Oct 2025'. The source confirms October 2025 as the conclusion date (when Bonta issued the statement and secured concessions). Working backward from October 2025 by 'year and a half' yields approximately April 2024, which is reasonably consistent with 'mid-2024' (within ~2 months). The claim is substantially confirmed but uses approximate language ('~mid-2024') that cannot be verified to exact precision from the source. The source does not explicitly state a start date, only the duration retrospectively.
