The rich keep getting richer, and Amazon CEO Jeff Bezos is living proof. 

CNBC reports Amazon's stock climbed 11 percent in extended trading Thursday after their revenue grew 21 percent for the fourth quarter, beating Wall Street expectations, and becoming the fourth company to surpass the trillion-dollar mark by the market cap in the United States, joining Apple, Alphabet, and Microsoft. All good news, financially, for Bezos, who owns more than 57 million shares of Amazon. 

The extended trading surge benefited Bezos by giving him an additional 11 figures in just 15 minutes, according to TMZ. Bloomberg claims Bezos netted $13.2 billion, which raised his net worth to about $129.5 billion while Forbes believes his takeaway was about $12.8 billion to give him a net worth of $128.9 billion. Regardless of where his new net worth sits, Bezos pulls further away from Bill Gates, who sits in second on Forbes' list of the richest people in the world. 

Even Bezos' ex-wife, MacKenzie, saw her dollars go up as someone who owns about four percent of Amazon. She was already the 24th-richest person in the world with $37.1 billion, and this latest increase will only add to her bottom line. MacKenzie vowed last May to donate at least half of her wealth to charity after her divorce was finalized. 

Last year, MacKenzie and Jeff announced that they were getting a divorce after 25 years of marriage. Bezos, who founded Amazon after the two were wed, didn't have her sign a prenup.
