Traders see the $900 billion to $1 trillion range as the most probable outcome for Elon Musk’s September 30 net worth because SpaceX’s post-IPO valuation has stabilized in the $1.5–2 trillion zone after June’s sharp correction, with Musk’s roughly 38 percent stake (including options) anchoring the bulk of his fortune. Tesla’s share price, representing his roughly 11 percent ownership, has shown modest resilience amid broader tech-sector sentiment, while the earlier xAI integration into SpaceX has consolidated AI-related upside without triggering fresh volatility. Market-implied odds reflect ongoing uncertainty around short-term swings in these two holdings, with limited catalysts expected before month-end beyond routine trading and any earnings-related moves.
