Which company had the largest market capitalization at the end of 2000?

General Electric had the largest market capitalization at the end of 2000.

General Electric, commonly called GE, was one of the world’s most valuable companies at the height of the dot-com era. Its diversified operations included aircraft engines, power equipment, appliances, industrial systems, and financial services. The breadth of the business helped it attract investors even as technology stocks dominated headlines.

The year 2000 marked the peak of the dot-com bubble. Companies such as Microsoft, Cisco, and Intel had enormous valuations, but GE’s market capitalization remained higher at the year’s end. Market-cap rankings from that period look very different from modern lists dominated by large technology and internet businesses.

GE later separated and sold many operations, while its remaining businesses were reorganized. In 2024, the former conglomerate completed its planned split into GE Aerospace and GE Vernova, illustrating why historical company comparisons require attention to corporate structure.
