Optionality
mixed, and asymmetric between the two ledgers — personally FREE (his ~$2-2.8B VC portfolio is his own to deploy, no known lockup) but the lever he actually pulls (OpenAI's capital) is LOCKED per board.yaml: ~85-90% pre-earmarked against ~$1.0-1.4T in compute obligations. His personal equity stake in the OpenAI Group PBC (part of the 47% employee/investor pool as of the Oct-2025 restructuring) is undisclosed in sourced material — treat any specific % as unconfirmed.
