Elon Musk, Jeff Bezos and Bill Gates have lost $115 billion in five month

This year, Musk, Bezos, and Gates have seen their net worths plummet by $115 billion.

Those figures come from Bloomberg's Billionaires Index, which tracks the world's 500 richest people.

The stock market decline has wiped out $115 billion from the net worth of Elon Musk, Jeff Bezos and Bill Gates in the past five months.

Bloomberg Billionaires Index shows Musk's worth has dropped by $46.4 billion, Bezos's is down $53.2 billion, and Gates has lost $15.1 billion.

Musk was worth $224 billion, Bezos $139 billion, and Gates $123 billion as of Friday.

In addition to being the world's third-richest person after Gates, Bernard Arnault is the chairman of LVMH, the French luxury  

The conglomerate's worth has declined by $44.7 billion since January to $133 billion.

Tesla and Amazon shares - the companies where Musk and Bezos are current and former CEOs 

account for most of Musk and Bezos' wealth, but Gates' holdings in Microsoft, which he co-founded, are relatively modest.

Musk owns a 15.6% stake in Tesla worth about $122 billion after the electric car maker's shares fell almost 37% this year.

In April, he acquired a 9.2% stake in Twitter, which raised questions about his commitment to Tesla 

A $44 billion takeover bid by Musk was funded by the sale of Tesla shares worth $8.4 billion.

With a more diversified portfolio, Gates has weathered the stock market downturn.
