Musk has officially put a merger on the table. SpaceX reported third-quarter revenue of $14.6 billion, up 161% year over year. Its shares rose more than 8% after hours, valuing the company at $2 trillion—well above Tesla’s entire market cap. That same day, Musk said the two companies had formed special committees to explore a merger, which could become the largest acquisition in history if it goes ahead. But he added that it would require approval from 50% of all shareholders, so calling the merger a done deal would be an overstatement. SpaceX shares barely moved by the close.
