SpaceX’s planned 2026 IPO, following its merger with xAI, stands as the main catalyst behind the 87% market-implied odds that Elon Musk reaches trillionaire status before 2027. With his net worth already hovering near $800 billion—driven primarily by roughly 40% ownership in the combined SpaceX-xAI entity valued at $1.25 trillion and a 12% Tesla stake—traders see the aerospace firm’s potential listing at $1.5–1.75 trillion as the decisive push. Tesla’s ongoing shift toward robotics and AI, alongside a shareholder-approved compensation package that could unlock hundreds of billions more if milestones are met, adds further momentum. Recent filings and analyst projections indicate the IPO could close the gap to $1 trillion within months, though any delay in regulatory approval or valuation shortfalls remains a key swing factor.
