OpenAI — Valuation: $500B

NoteThe source directly confirms the claim. The CNBC article states 'The startup is currently valued at $500 billion' in the section discussing OpenAI's completed restructuring into a nonprofit with a controlling equity stake in its for-profit business (OpenAI Group PBC). The timing matches the claim's 'as of 2025-10' specification, and the valuation figure ($500 billion = 500,000,000,000) matches exactly. The claim's exact stored value is confirmed by the source's explicit statement.
