Facebook Founder Mark Zuckerberg Loses $18.8 Billion In Two Hours

Mark Zuckerberg lost nearly $20billion in just two hours on Wednesday.

The Facebook CEO saw his net worth tumble by $18.8billion, a record drop, in after-hours trading, taking him down four spots in Forbes' World Billionaires List.

Zuckerberg woke up as the fourth richest person in the world with an $82.4billion net worth on Wednesday but was in the eighth spot by the end of the day. 

The massive hit came as Facebook's shares plunged by $150billion after the tech giant failed to meet Wall Street's estimates for user growth and quarterly revenue.
