Trader consensus on Polymarket tilts slightly toward Elon Musk's net worth exceeding $670 billion by April 30 per Bloomberg Billionaires Index, at 31% implied probability, fueled by SpaceX's early April confidential IPO filing targeting a $1.75-2 trillion valuation—boosting his 44% stake in the SpaceX-xAI entity—and a recent $20 billion daily surge to $658 billion on April 15 amid Tesla stock stabilization around $352. Tesla's sharp YTD decline from weak Q1 deliveries has capped higher bins, while the April 22 earnings report looms as the key swing factor, with analysts eyeing EPS beats or robotaxi updates to propel shares upward; lower brackets like sub-$600 billion reflect downside risks from misses or market headwinds, underscoring the high uncertainty in Musk's volatile empire.
