Billionaires Elon Musk, Jeff Bezos and Bill Gates have suffered a collective loss of $ 115 billion this year as stock markets plummeted.

According to the Billionaires Index published by Bloomberg, Musk's wealth has fallen by 46.4 billion dollars, Bezos's by 53.2 billion dollars, while Gates's has 15.1 billion dollars, the Telegraph reports.

Bernard Arnault, the owner of the French conglomerate LVMH and the third richest person in the world, has suffered a drop of 44.7 billion dollars in its value since January to 133 billion dollars.

Much of Musk and Bezos's fortune is tied to the shares of Tesla and Amazon.

Musk has a 15.6 percent stake in Tesla worth about $ 122 billion as shares in the electric car maker fell nearly 37 percent this year.

He also bought a 9.2 percent stake in Twitter, prompting investors to question his commitment to Tesla.

Musk sold $ 8.4 billion worth of Tesla shares to fund his subsequent $ 44 billion takeover bid.

Gates has a more diversified portfolio, which has helped him withstand changes in the stock market.

The Bill & Melinda Gates Foundation, the philanthropic organization he set up with his ex-wife, has invested heavily in Warren Buffett's Berkshire Hathaway, which has grown by more than 5 percent this year.

But other investments, including his own company Cascade Investments which invests in technology companies like Apple, have had a more difficult development.

Bezos, who founded Amazon, still owns about 50 million shares in the company, valued at about $ 115 billion.
