Musk revives the idea of putting Tesla and SpaceX together

Elon Musk has again hinted that Tesla and SpaceX could one day become a single company, saying their growing cooperation raises the question of why they remain separate. He did not announce a deal, a timetable, or even a formal plan, so this is still a signal rather than a transaction. The idea matters because it would join businesses with very different core products—electric vehicles, batteries, rockets, and satellite connectivity—under one corporate structure. For now, Musk appears to be testing the logic of deeper integration as the companies increasingly work alongside each other, not telling investors that a merger is imminent.
