Recent gains in SpaceX valuation following its merger with xAI, which created a combined entity now valued near $1.25 trillion, have pushed Elon Musk’s net worth above $840 billion and lifted the implied probability of him reaching trillionaire status before 2027 to 88 percent. Traders are focusing on SpaceX’s planned 2026 IPO and Starlink’s expanding satellite network as the clearest path to crossing the threshold, while Tesla’s ongoing progress in autonomous driving and robotics provides additional upside. With roughly two-thirds of Musk’s holdings tied to private SpaceX-xAI shares, any successful public listing at or above $1.5 trillion could close the remaining gap within months, though execution risks and broader market conditions remain key swing factors.
