Amazon founder and executive chairman Jeff Bezos is planning to sell some of his holdings in the company.

Bezos, whose net worth is valued at over $200 billion, will sell up to 25 million shares in the company, valued at around $5 billion, Amazon disclosed in a regulatory filing Friday. The value of the shares could change, of course, depending on Amazon’s stock price. If it declines, they would be worth less, if it rises, they would be worth more.

Amazon filed its quarterly 10-Q report with the Securities and Exchange Commission Friday morning, revealing a 10b5-1 trading plan for Bezos. The plans are meant to preempt concerns of insider trading by creating a pre-planned schedule for sales that are executed automatically when certain stock conditions are met.

The specifics of the trading plan were not disclosed, beyond the 25 million share figure, and an end date of May 29, 2026. For comparison, Disney CEO Bob Iger disclosed a 10b5-1 plan late last year covering about $41 million in stock.

Bezos, it should be noted, has consistently sold a small portion of his Amazon holdings for the last couple of years to help fund his other ventures, which include The Washington Post and the space firm Blue Origin. Last year, for example, he filed a trading plan that covered up to 50 million shares in the company.

The planned sale comes amid a challenging environment for Amazon, which is navigating tariff uncertainty. That said, the company’s advertising business continues to surge, growing 19 percent in Q1 to $13.9 billion.
