Elon Musk's post reignites Tesla and SpaceX merger speculation alongside Roadster flight rumors

Elon Musk paired 'Tesla x SpaceX' with the Roadster livestream link, reviving merger speculation, though neither company has confirmed talks. Polymarket bettors give the Roadster a 60% chance of flying for one second or more, supported by reports of a remotely operated Roadster using SpaceX thrusters. SpaceX went public on June 12 at $135 a share, achieving a $1.77 trillion valuation, and later reached a $2.07 trillion market value on October 14, while Tesla shares are down about 18% this year. Barclays suggests SpaceX buying Tesla with stock, potentially leaving Musk with 37% equity and 56% votes, and a deal could surface before Tesla's annual shareholder meeting by December 6.
