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 start around April 2024, consistent with 'mid-2024'). The source confirms the investigation was 'conducted' (past tense) as of Oct 2025, supporting 'concluded Oct 2025'. However, the source does not explicitly state a start date or use the word 'concluded'—it only states the investigation was conducted 'over the last year and a half' and that Bonta will 'not be in court opposing' the plan going forward. This is consistent with conclusion but not explicitly stated. The claim's temporal specificity (~mid-2024 start, Oct 2025 conclusion) is partially supported but not fully explicit in the source.
