Jeff Bezos is cashing out some of his Amazon shares as the stock hit an all-time high this week.

The Amazon cofounder filed a notice with the SEC to sell 25 million Amazon shares worth close to $5 billion on Tuesday.

Bezos filed the notice after Amazon stock prices hit $200.43. Last week, Amazon's market cap also reached $2 trillion for the first time.

Bezos will still have over 900 million Amazon shares after this share sale, so he's nowhere near handing off his stake in the company.
