Warren Buffett, the legendary investor and longtime chairman of Berkshire Hathaway, has built his fortune on unglamorous businesses. As the AI boom drives demand for data centers, Berkshire's utility and energy subsidiaries are positioned to benefit from the surge in electricity consumption.
Berkshire Hathaway owns a diverse portfolio of companies, including insurance, railroads, and utilities. Its energy division, Berkshire Hathaway Energy, operates regulated utilities and power generation assets. With AI data centers requiring massive amounts of electricity, these utilities are seeing increased demand.
Buffett has historically avoided investing in technology companies he doesn't understand, but his conglomerate's infrastructure holdings provide indirect exposure to the AI trend. The company's railroad, BNSF, also transports materials and goods that support data center construction.
While Buffett stepped down as CEO in 2025, his investment philosophy continues to shape Berkshire's strategy. The company remains a major player in the energy sector, and its utilities are investing in grid upgrades and renewable energy to meet growing power needs.
