NoteThe source directly states in its headline and opening paragraph that 'Microsoft's stake in OpenAI has a number: $135 billion, or roughly 27% of the AI company.' This exactly matches the claim being verified. The article provides context that this disclosure was made as part of OpenAI's recapitalization as a public benefit corporation.
