Trader consensus on Polymarket reflects a 69% implied probability for Elon Musk reaching trillionaire status before 2027, propelled by SpaceX's February 2026 merger with xAI, which valued the combined entity at $1.25 trillion and boosted Musk's stake to approximately 43%, pushing his net worth past $800 billion to around $839 billion per recent Forbes estimates. Surging Starlink revenues and Starship milestones have fueled SpaceX's valuation trajectory, while Tesla's strong stock performance amid full self-driving advancements and Optimus robot deployments adds momentum. Traders eye an imminent SpaceX IPO, potentially at $1.75 trillion mid-2026, as the key catalyst to bridge the remaining $160 billion gap, though regulatory hurdles or market volatility could introduce delays.
