Musk has reaffirmed that Tesla and SpaceX are in merger talks, but emphasized that a deal is not guaranteed. The two companies have formed special committees to explore the possibility, though Musk has stepped back from the negotiations to avoid any potential conflicts of interest. The proposed merger would combine Tesla's electric vehicles, energy business and robotics efforts with SpaceX's rockets, satellite internet and AI operations.

Musk believes the combination could be the largest corporate merger ever, with the potential to revolutionize industries through cooperation on superintelligence software. However, he cautioned that the process might not result in a final agreement as it would require shareholder support.
