Berkshire Hathaway

Warren Buffett's Berkshire Hathaway crossed $1 trillion in market cap in 2024, becoming the first non-tech US company to reach that milestone. The conglomerate's value comes from its wholly owned subsidiaries — including GEICO, BNSF Railway, and Berkshire Hathaway Energy — plus a $300 billion-plus public stock portfolio anchored by its massive Apple stake. Buffett's announcement of a succession plan naming Greg Abel as his successor has reassured long-term investors, and Berkshire's record $325 billion cash pile positions it for a major acquisition.
