According to Bloomberg’s calculations, Elon Musk has recaptured the title of richest person in the world. In December of last year, Bernard Arnault, CEO of the French luxury retailer LVMH (LVMHF), deposed the Tesla CEO from the top rank, placing Musk at No. 2 for more than two months. Yet as of Monday, according to Bloomberg, a surge in Tesla stock has sent Musk back to the top of the Billionaires Index.

Musk’s net worth was some $187.1 billion as of Monday after markets closed, according to Bloomberg, just topping the $185.3 billion fortune of Arnault. While Tesla (TSLA) stock declined steeply last year amid Musk’s problem-plagued acquisition of Twitter and a broader market downturn in tech, shares for the electric vehicle maker have since surged in 2023.

Musk might hold the current title of the richest person in the world, but he also holds a record for the biggest fortune ever lost by anyone in history. Late last year, Musk became the first person ever to lose $200 billion in wealth — after his net worth slid from some $340 billion in Nov. 2021 to $137 billion in Dec. 2022.
