Tesla shares trading near $350–400 this month, combined with the restored 2018 compensation package and the SpaceX-xAI merger valued at $1.25 trillion earlier this year, anchor Elon Musk’s net worth estimates between $650 billion and $800 billion. These holdings—roughly 13–15 percent of Tesla plus vested options and a 42 percent stake in the merged private entity—account for the bulk of his fortune, with the 58 percent market-implied odds on a May 31 reading above $690 billion reflecting recent price stability and limited near-term volatility. Traders are pricing in steady equity markets and no major regulatory or operational shocks before month-end, while narrower buckets below $670 billion capture the residual risk from private-asset valuation swings.
