The 68% drop in Tesla stock this year has left Musk $132 billion poorer, but still at the top of Forbes’ billionaires list, Business Insider writes.

Musk’s stock drop is due to investor concerns that Musk may be focusing too much on his various business ventures.

As of today, Musk’s total fortune is about $139 billion. However, the decline in his wealth will be exacerbated judging by Tuesday’s trading session for Tesla shares, as their nearly 10% sell-off will eat up roughly $7 billion to $8 billion of Musk’s equity.

Bernard Arnault, who is co-founder and CEO of LVMH (EPA:LVMH), is $20 billion richer than Musk and has reclaimed his spot as the world’s richest man. And Indian businessman Gautam Adani is third in the billionaire ranking with $110 billion.

Earlier this year, Musk’s net worth was just over $300 billion.

After acquiring Twitter (NYSE:TWTR) for $44 billion in late October, Tesla shares fell 50% compared to the Nasdaq 100’s plunge – the index fell 3%. Musk also sold billions of dollars worth of Tesla stock to acquire Twitter.

Musk’s stake in SpaceX now makes up his most valuable asset worth $47 billion. Meanwhile, Musk’s stake in Tesla is worth about $40 billion, and his options in Tesla are worth another $28 billion.

The next most valuable asset Musk owns is Twitter, which is worth $20 billion, about half of what Musk paid.
