According to this CNBC video, Jeff Bezos is planning to sell another 865,000 shares of Amazon stock, following another filing last week where he indicated plans to sell $25 million worth of shares. This recent filing translates to roughly $863.5 million worth of shares. Bezos has been selling shares through a 10b5-1 plan, which allows him to pre-schedule stock sales to avoid accusations of insider trading. The filing does not specify why Bezos is selling the shares, but he has been funding private endeavors like Blue Origin and giving away shares to philanthropic causes.
