Recent rebounds in SpaceX and Tesla shares have returned Elon Musk’s net worth above $1 trillion as of early October 2026, with SpaceX (now the dominant driver after its June IPO) up roughly 13% month-to-date on analyst optimism around Starship progress, Starlink growth, and AI initiatives, while Tesla gained on stronger Q3 deliveries. The market’s tight clustering between the $900B–$1.0T and $1.0–$1.1T brackets reflects this concentration of wealth in two volatile equities, historical post-IPO swings, and uncertainty over near-term catalysts including Tesla’s October 21 earnings report and the next Starship flight. Traders appear to weigh continued recovery momentum against the potential for rapid reversals in either stock.
