Elon Musk has regained his position as the richest man in the world.
The two centibillionaires, a term used to refer to people with wealth greater than $100 billion, are neck and neck for the top spot for months.
This week, Arnault’s wealth slipped after a drop in LVMH stock on Wednesday, according to Bloomberg calculations.
Arnault surpassed Musk in December, as his fortune soared thanks to a boom in sales of luxury goods that helped boost LVMH’s stock price. LVMH, one of the world’s largest conglomerates, is home to brands including Louis Vuitton, Dior and Celine.
Musk, meanwhile, was satisfied with a meteoric rise on the world’s rich lists in recent years because his fortunes are directly linked to Tesla, the electric automaker. His biggest asset is the company’s stock, of which he owns about 13%, according to Bloomberg.
Outside of Tesla, Musk is also the CEO of SpaceX, the space exploration firm, and the owner of the social network Twitter.
LVMH shares are up 19.7% this year, while Tesla is up 65.6% year to date.
