Berkshire Hathaway was the first U.S. company outside the tech sector to reach a $1 trillion market cap. It started as a textile company and remained in that business for more than a century, but it's perhaps most well-known for its ties to legendary investor Warren Buffett.

After serving as Berkshire's CEO for 60 years, Buffett retired at the end of 2025. Greg Abel took over as CEO, with Buffett still serving as chairman of the board. While Berkshire's primary business is insurance (it owns one of the largest insurance companies, GEICO), it has also invested in companies across various industries.
