Elon Musk’s fortune soared Thursday, rising above $788 billion to a new record high as Tesla’s stock rose after Musk said the company’s robotaxi fleet would be “widespread” by year’s end.

Forbes’ Real-Time Billionaires List put Musk’s estimated net worth at $788.1 billion as markets closed Thursday, with Tesla shares rallying more than 4%.

This surpasses Musk’s previous record of $780 billion recorded Friday.
