Tesla Inc chief and billionaire entrepreneur Elon Musk surpassed Amazon.com Inc's top boss Jeff Bezos to become the world's richest man, Bloomberg News reported on Thursday.
Including Thursday's gains in Tesla shares, Musk, 49, had a net worth of more than $188.5 billion, $1.5 billion more than Bezos, the report said.
Musk's personal wealth has been boosted by last year's more than eight-fold surge in the shares of Tesla, which became the world's most valuable carmaker.
