Polymarket Gives 18% Odds to a Tesla-SpaceX Merger Announcement in 2026

The article says Polymarket traders are assigning only an 18% probability that Tesla and SpaceX will announce a merger by the end of 2026, with the nearer-term September 30 contract near 5%. Despite speculation around Elon Musk’s companies, the market is skeptical due to major structural and regulatory hurdles, including Tesla’s reported consideration of separating its China business and the geopolitical sensitivity of combining a China-linked automaker with SpaceX, a U.S. defense contractor. The piece also notes that total volume on the relevant contracts has surpassed $1 million, showing strong interest. Tesla-related sentiment is cautious, as the market appears to price in low odds of a merger announcement rather than any imminent corporate action.
