OpenAI — Legal Structure: Nonprofit 501(c)(3)

NoteThe claim states OpenAI's legal structure was 'Nonprofit 501(c)(3) (as of 2015-12)' with additional context that it was 'Originally incorporated as nonprofit OpenAI Inc.' The source is the official OpenAI blog post from December 11, 2015, which explicitly describes OpenAI as a 'non-profit' organization. While the source does not explicitly state the IRS tax classification '501(c)(3)', it confirms the nonprofit status as of the exact date claimed (December 2015). The nonprofit designation is stated clearly and repeatedly. The 501(c)(3) classification is a standard U.S. nonprofit tax status and is consistent with the nonprofit designation stated in the source, though not explicitly mentioned in this excerpt.
