Recent volatility in SpaceX and Tesla shares has anchored trader sentiment for Elon Musk’s net worth on October 31, with the market-implied odds favoring the $900 billion–$1 trillion range at 43.5 percent. SpaceX, which accounts for roughly three-quarters of his fortune following its June 2026 IPO, has swung sharply on analyst commentary, potential capital raises for AI hardware, and broader tech valuations, recently pulling Musk’s wealth back above and then below the trillion-dollar threshold. Tesla’s better-than-expected Q3 deliveries provided a modest lift, yet ongoing sensitivity to daily price moves—each 1 percent shift in SpaceX alone can alter his net worth by billions—keeps the outcome closely contested ahead of month-end. Traders appear focused on near-term stock stability rather than longer-term catalysts like Starship progress or xAI developments.
