Tesla CEO Elon Musk's net worth surged to $749 billion late Friday after the Delaware Supreme Court reinstated Tesla stock options worth $139 billion that were voided last year, according to Forbes' billionaires index, Reuters reported. 

Musk's 2018 pay package, once worth $56 billion, was restored by the Delaware Supreme Court on Friday, two years after a lower court struck down the compensation deal as "unfathomable."

The Supreme Court said that a 2024 ruling that rescinded the pay package had been improper and inequitable to Musk, according to Reuters.
