Trader consensus on Polymarket clusters tightly around $620-670 billion for Elon Musk's net worth on April 30, reflecting stabilization after February's SpaceX-xAI merger that briefly pushed estimates above $800 billion per Forbes before Bloomberg's conservative $632 billion as of March 31 amid a 5% private valuation discount. Tesla's stock, hovering near $400 after a 17% YTD decline, drives the uncertainty, with Q1 earnings expected April 21-28 serving as the pivotal swing factor—strong deliveries, FSD updates, or robotaxi progress could lift toward 660-670b, while margin pressures tip below 620b. SpaceX IPO rumors at $1.75 trillion add speculative upside, but traders price in high volatility from market sentiment and private asset opacity.
