**Trader consensus on Polymarket has converged overwhelmingly on Elon Musk’s net worth landing in the $900B–$1T range on September 30, 2026, driven by the post-IPO stabilization of SpaceX shares and steady Tesla performance.** SpaceX’s June 2026 public debut briefly propelled Musk past $1.4T at peak valuations near $2T market cap, but subsequent share-price corrections of roughly 30–50% from highs—tied to liquidity adjustments and market reassessment—reduced his roughly 38% stake (including options) to the dominant but moderated contribution in the high $600B–$700B area. Tesla holdings, representing about 11–20% ownership depending on restricted-award treatment, added roughly $140B–$250B at late-September closes near $355 per share, keeping the total firmly in the targeted band per Forbes and Bloomberg trackers. This skin-in-the-game pricing reflects trader recognition that major near-term catalysts, such as Q3 delivery figures or further SpaceX operational updates, would need to produce outsized moves to push outside the $900B–$1T window before resolution.
