Jeff Bezos with fans

From time to time, it's especially good to be Jeff Bezos.

The Amazon CEO made another massive paper gain on Thursday after the company crushed earnings expectations .

With the stock up 10.5 percent in after-hours trading, or $58.97 per share, Bezos' 82.9 million shares showed a gain of about $4.89 billion.

It's not the first time Bezos made a mint on earnings either — in July he posted a paper gain of $8 billion after-hours on another strong report.

But Bezos wasn't alone in having a lucrative night.

Google beat estimates and announced a significant share buyback , sending the stock 9 percent higher in evening trading.

That was enough to make co-founders Larry Page and Sergey Brin $1.46 billion and $1.41 billion, respectively.

They also racked up billions in gains after July's earnings report, just as Bezos did.
