After the sale, Bezos owns 81.91 million shares (~17% of Amazon).

This sale comes after Amazon reported a stellar first quarter last week. The company had a huge beat across the board, and the stock shot up 12% in after-hours trading. Amazon grew profitability, its Amazon Web Services arm, and its international business. And Wall Street loved it, as evidenced by gushing analysts notes in the aftermath.
