Amazon's stock is up nearly 18% after hours after the company reported a surprise profit for the second quarter. The stock spike sent CEO Jeff Bezos' personal net worth soaring by about $7 billion.

Bezos owns 83,921,121 Amazon shares, according to CNBC.

His net worth is now estimated at $50 billion.

Amazon reported a net income of $92 million, or 19 cents a share. Analysts were expecting the ecommerce giant to post a loss of 14 cents a share. At this time last year, Amazon lost 27 cents per share.
