Recent regulatory approvals for Tesla robotaxi operations in Nevada and Texas, alongside the September 3 Cybercab launch event, serve as the main catalyst supporting the $900B–$1T bracket at 40.5% implied probability. Tesla shares, which comprise roughly 16% of Musk’s holdings, have rebounded modestly on full self-driving progress and autonomy milestones even as capital expenditure concerns and macro pressures keep valuations in check. SpaceX accounts for over 80% of net worth but faces a June 2027 lockup, limiting near-term moves, while broader AI and EV market sentiment continues to influence trader consensus on the final September 30 reading.
