In the past week, Amazon.com founder and Executive Chair Jeff Bezos sold 7.4 million shares of the retail and cloud company for $1.7 billion.

These sales are part of so-called 10b5-1 trading plans that allow company insiders to pre-announce share sales so they don’t spook markets when they happen. Trading plans are meant to remove the appearance of bias from the knowledge of nonpublic information. They automatically execute trades when preset conditions, such as price, volume, and timing, are met.

Bezos’ current plan covering the sale of 25 million shares was disclosed in April when Amazon filed its first-quarter report to the Securities and Exchange Commission.

This is Bezos’ fourth such plan in 2024 and 2025. So far he has sold 89 million shares at an average price of $188.28, bringing in $16.7 billion. Bezos has also gifted 4.5 million Amazon shares to charity in this period, worth about $1 billion. He has about 11 million shares left to sell on his current plan.

Bezos still owns over a billion Amazon shares, worth $231 billion.
