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 statement date and 'year and a half' duration (which would place the start around April 2024, consistent with 'mid-2024'). The source does not explicitly state a conclusion date—it says the AG 'will not be in court opposing' the plan, suggesting the investigation concluded, but uses forward-looking language ('we will be keeping a close eye'). The claim's specific start date of 'mid-2024' is inferrable but not explicitly stated in the source. The investigation's conclusion is implied but not explicitly confirmed as 'concluded Oct 2025'—the statement is from October 28, 2025, but doesn't explicitly say the investigation concluded on that date.
