As of 2026, Jeff Bezos owns a diverse portfolio of major companies, most notably The Washington Post, which he purchased privately in 2013, and the aerospace manufacturer Blue Origin. While he stepped down as CEO of Amazon in 2021, he remains its Executive Chairman and its largest individual shareholder, effectively maintaining significant influence over the e-commerce and cloud computing giant. Beyond these "big three," Bezos operates Bezos Expeditions, a venture capital firm through which he has held stakes in companies like Airbnb, Uber, and Google, and more recently, AI-focused firms like Perplexity AI and Physical Intelligence. He also founded the Bezos Earth Fund, a $10 billion commitment to climate change, and Altos Labs, a biotechnology company focused on cellular rejuvenation. While he is most synonymous with Amazon, his current "ownership" and investment reach spans media, space exploration, artificial intelligence, and global philanthropy, making him one of the most prolific venture capitalists in history.
