It is true according to Forbes, Amazon CEO Jeff Bezos is now the richest person in the world for the second time as Amazon stock opened up more than 8% higher than Thursday’s close, adding nearly $7 billion to Bezos’ net worth overnight.

Bezos had a net worth of $89.7 billion, as of the start of trading on Friday, while Gates had a net worth of $90.1 billion, up $550 million from yesterday. Then 10:15 a.m. Eastern, Amazon stock had climbed nearly 2% since the market opened, adding $900 million to Bezos’ net worth and putting him in the No. 1 spot with a net worth of $90.6 billion versus Gates’ $90.1 billion at that time.  

Amazon stock surged in after-hours trading on Thursday after the company reported strong third quarter earnings. Amazon reported $43.7 billion in revenue, well above the $42.1 billion analysts expected.

Bezos became the richest person in the world for the first time three months ago as Amazon stock hit an all-time high on July 27, just before Amazon reported its second quarter earnings. But Bezos’ first time at the top of Forbes’ Real-Time Billionaires List only lasted a few hours.

Bezos first joined the Forbes 400 in 1998, one year after Amazon went public, with a net worth of $1.6 billion.
