Which company was the first to exceed a $1 trillion market capitalization while led by Warren Buffett?

Berkshire Hathaway was the first company led by Warren Buffett to exceed a $1 trillion market capitalization, in August 2024.

Berkshire Hathaway passed the $1 trillion valuation mark on August 28, 2024, making it the first U.S. company outside the technology sector to reach that level. Investors value Berkshire as a diversified holding company whose businesses include insurance, railroads, utilities, energy, manufacturing, and consumer brands.

Berkshire is unusual among very large companies because it has historically avoided paying a regular dividend. Instead, management has generally retained earnings for acquisitions and investments, while Buffett has emphasized long-term ownership of durable businesses.

The company began as a textile manufacturer before Buffett and his associates transformed it into an investment and operating conglomerate. Buffett became its chairman and chief executive in 1965, and Greg Abel is designated as his successor as CEO.
