OpenAI — Valuation: $500B

NoteThe source directly confirms the claim's valuation figure. The CNBC article explicitly states 'The startup is currently valued at $500 billion' in the section discussing OpenAI's completed restructuring into a nonprofit with a controlling stake in its for-profit business (OpenAI Group PBC), announced in October 2025. The exact stored value in the claim (500,000,000,000) matches the source's stated $500 billion valuation. The temporal context also aligns: the claim specifies 'as of 2025-10' and the source article is dated 2025-10-28, discussing the October 2025 restructuring announcement.
