Bernard Arnault just became the 2nd-richest person in the world. These 5 mind-blowing facts show just how quickly the French billionaire's fortune is growing.

1. In January 2019, Arnault was ranked No. 4 on the lists of the world's richest people. Fast forward six months to mid-July, and he's jumped two major spots, up to No. 2.

His net worth was $68.6 billion on January 1, according to Bloomberg.

Now, it's $108 billion, according to Bloomberg.

2. In the first three months of 2019, Arnault added over $14 billion to his net worth — roughly the equivalent of drug lord El Chapo's entire empire.

By March, Arnault had already added over $14 billion to his net worth, pushing his net worth ahead of Buffett's according to Bloomberg.

Law enforcement estimates that El Chapo's entire drug empire is worth $14 billion, Business Insider previously reported.
