Trader consensus on Polymarket assigns a 74.5% implied probability to Elon Musk achieving trillionaire status before 2027, propelled by SpaceX's valuation leap to $1.25 trillion following its February xAI merger and recent confidential IPO filing targeting $1.75 trillion or higher. Musk's net worth, estimated at $650–850 billion primarily from his stakes in SpaceX (Starlink, Starship) and Tesla (FSD, Optimus robots), has surged $16 billion in April alone amid hype for space-based AI data centers blending xAI's large-scale training clusters with orbital infrastructure. Key catalysts include the anticipated June SpaceX IPO—the largest in history—and Tesla's high P/E ratio signaling robotaxi and humanoid expansion, though valuation volatility and regulatory hurdles for Starship launches pose risks to this aggressive timeline.
