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