Elon Musk's post pairing “Tesla x SpaceX” with a Roadster livestream link revived merger speculation, while Polymarket bettors put the chance of the car flying for at least one second at 60%. According to BeInCrypto, neither Tesla nor SpaceX has confirmed merger talks; Barclays sees a stock-funded SpaceX acquisition of Tesla as the likelier route, while Wedbush analyst Dan Ives puts the odds of a merger above 80% by 2027. Musk said any combination would need a proper process.
