What energy stock did Warren Buffett buy?

Written by Editorial Team | Last Updated: August 2026

Warren Buffett and his conglomerate Berkshire Hathaway have notably invested heavily in major traditional energy corporations, most prominently Occidental Petroleum and Chevron Corporation. Berkshire built a massive multi-billion-dollar equity stake in Occidental Petroleum, acquiring a significant percentage of its common stock alongside regulatory approvals to purchase up to a substantial ownership threshold. Additionally, Berkshire Hathaway accumulated billions of dollars worth of shares in Chevron Corporation, establishing it as another core pillar of their public equity portfolio. These strategic acquisitions reflect a calculated thesis centered on the enduring necessity of conventional oil and gas infrastructure, long-term supply and demand fundamentals, and attractive valuation metrics within the traditional fossil fuel hydrocarbon sector despite broader market skepticism.

Warren Buffett's conglomerate, Berkshire Hathaway, has maintained a massive multi-billion-dollar position in Chevron Corporation, making it one of the largest equity holdings in his portfolio. Berkshire has consistently adjusted its stake, including purchasing millions of additional shares in Chevron to reinforce its conviction in traditional petroleum exploration and production. In addition to Chevron, Buffett's energy investments historically include massive financial commitments to Occidental Petroleum and the direct ownership of regulated utility giants under Berkshire Hathaway Energy, highlighting his preference for cash-generative integrated energy businesses.
