Tesla's share price strength through late May, closing near $436 amid sustained investor focus on AI, robotics, and EV growth, served as the dominant driver behind the market's near-certain pricing of Elon Musk's net worth above $690 billion on May 31. His primary holdings in Tesla, SpaceX, and xAI benefited from elevated private valuations and broader equity market resilience, pushing Bloomberg and Forbes estimates into the $735–835 billion range. This skin-in-the-game consensus reflects real capital allocation reflecting these fundamentals. A sharp, unexpected decline in Tesla shares or downward revisions to SpaceX valuations before the May 31 close represent the main scenarios that could have altered the outcome, though none materialized.
