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, explicitly describing OpenAI as a 'non-profit artificial intelligence research company.' While the source does not explicitly state the '501(c)(3)' tax classification, it confirms the nonprofit status as of the exact date claimed (December 2015). The 501(c)(3) designation is a standard U.S. nonprofit tax classification and is consistent with the nonprofit status confirmed in the source. The source confirms the core claim about legal structure (nonprofit) and timing (December 2015).
