SpaceX’s February 2026 merger with xAI at a combined $1.25 trillion valuation lifted Elon Musk’s net worth past $850 billion, placing him within striking distance of trillionaire status well before 2027. Traders assign an 87.5 percent implied probability to “Yes” because Musk holds roughly 43 percent of the merged entity, and a planned 2026 IPO targeting $1.75–2 trillion would add hundreds of billions more to his stake alone. Tesla’s ongoing advances in full self-driving software and Optimus robotics provide additional upside, while historical patterns show Musk’s wealth has compounded rapidly during AI and autonomy cycles. The dominant remaining uncertainty centers on IPO execution timing and market reception, yet current momentum strongly favors crossing the threshold on schedule.
