Twitter CEO, Elon Musk has regained his title as the world’s richest man after briefly losing it to the LVMH French businessman, Bernard Arnault. 

According to Bloomberg, a surge in Tesla stock has placed Musk back to the top of the Billionaires Index.

As of Monday, February 27, after the markets closed, Musk’s net worth was approximately $187.1 billion, surpassing Arnault’s $185.3 billion fortune.

Musk’s wealth was boosted nearly 70% surge in Tesla Inc.’s stock price this year, about 100% from its intraday low on January 6 as investors pile back into bets on riskier growth stocks amid signs of economic strength and a slower pace of Federal Reserve interest-rate increases.

The company has also benefited from more demand for its electric vehicles after cutting prices on several models.
