In 2025, the top 20 tech billionaires collectively sold more than $19 billion in stocks, capitalizing on the AI boom. Notable figures include Jeff Bezos, who sold $5.6 billion in Amazon shares, and Michael Dell, who offloaded $2.2 billion in Dell stock. Safra Catz, former CEO of Oracle, cashed out $1.9 billion, marking a significant portion of her net worth. The sell-offs come as the AI market remains robust, though concerns about a potential bubble are rising. Some billionaires, like Bezos, are reinvesting in ventures such as his AI startup, Project Prometheus, while others, like Dell, are using proceeds for philanthropic efforts. Despite the trend, Elon Musk and Larry Ellison opted to leverage their stock holdings through pledges rather than sales, avoiding capital gains taxes.
