Recent declines in Tesla and SpaceX valuations after the June 2026 SpaceX IPO have driven Elon Musk's net worth below $1 trillion to around $740 billion by late July, positioning the $600–700 billion range as the leading market outcome. Trader sentiment reflects ongoing volatility from Tesla's robotaxi and Optimus robot bets amid analyst skepticism on near-term revenue, combined with SpaceX share pressure ahead of lockup expirations and Starship test flights. The 45.5% implied probability on $600–700 billion and 24% chance of sub-$600 billion capture expectations of further short-term swings in these core holdings, while lower odds on higher brackets acknowledge limited near-term catalysts before August 31. Market-implied odds aggregate real-capital assessments of these tech and regulatory dynamics.
