Mark Zuckerberg, Jeff Bezos gain over $1 billion in net worth after stocks rally

As stocks for Facebook and Amazon rallied on Wednesday, both Mark Zuckerberg and Jeff Bezos smiled to the bank as the market capitalizations of both companies crossed the $300 billion mark.

Facebook shares reached $107.75 in after-hours trading, after quarterly results showed that Zuckerberg’s mobile advertising engine is on song.

That ultimately translated into a market capitalization of $303.6 billion, taking the social media giant above General Electric.

That gain, in addition to the state of the stocks before the quarterly results were announced, added over $1 billion to Zuckerberg’s net worth.

According to Forbes, Amazon had jumped into the $300 billion club earlier in the day when it’s stock reached as high as $645.93, adding about $1.3 billion to founder Bezos’ net worth.

These gains in share price means six of the eight companies with over $300 billion in market capitalization are from the tech sector.
