Which company became the world’s most valuable public company in 2000 before the dot-com crash?

General Electric became the world’s most valuable public company in 2000 before the dot-com crash.

General Electric held the top market-cap position around the turn of the millennium, when its diversified businesses and strong reputation under chief executive Jack Welch supported a very high valuation. Its activities included industrial equipment, aviation, power, appliances, finance, and media.

The company’s position is a useful reminder that the largest company by market capitalization has changed repeatedly across industries. Technology businesses dominated many later rankings, while GE’s earlier strength came from diversification and the scale of its industrial and financial operations.

GE’s market value later declined as its finance arm suffered during the global financial crisis and investors questioned the complexity of the conglomerate. The company subsequently separated major businesses, including GE Healthcare, GE Vernova, and GE Aerospace. These changes mean that the historic GE was much broader than the businesses carrying GE-related names today.
