Amazon founder Jeff Bezos has seen his stake in the company fall below 10%. In a recent filing with the U.S. Securities and Exchange Commission (SEC), he disclosed that he currently holds approximately 9% of Amazon's outstanding shares after selling over 100 million shares in the past year. Regulatory records reveal that one year ago, Bezos controlled about 10.1% of Amazon's shares. When Amazon went public in 1997, he held over 43%. When Bezos stepped down as CEO in 2021 and handed over the day-to-day operations to his successor Andy Jassy, he possessed approximately 14% of the company. In February of this year, he filed to sell 25 million shares, which was estimated to yield about $5 billion based on Amazon's stock price at that time. Subsequent filings in August indicated Bezos planned to sell another 25 million shares, valued at around $5.4 billion. According to disclosures to the SEC, he has also donated over 500,000 shares of Amazon stock to charitable organizations in recent months. Since the end of April, Amazon's stock price has surged by 38%, providing an ideal opportunity for Bezos to cash in on some of his holdings. This surge follows significant investor bets on the company's AI advancements and cost-cutting initiatives under Jassy's leadership. Even after the recent sell-off, Bezos remains one of the richest individuals in the world. According to the Bloomberg Billionaires Index, his net worth is approximately $239 billion as of Wednesday's close, ranking him fourth among the world's billionaires, following Elon Musk, Larry Ellison, and Mark Zuckerberg.
