In the second quarter of this year, Tesla's once-dominant share of the United States electric vehicle market dropped to below 50 percent for the first time, according to new estimates by Cox Automotive. Despite a record surge in sales of battery-powered cars, Tesla's market share fell to 49.7 percent, down from 59.3 percent the previous year. Competitors like General Motors, Ford Motor, Hyundai, and Kia have gained ground on Tesla, signaling a shift in the market. Overall, U.S. electric vehicle sales increased by 11.3 percent from the previous year, with over 330,000 electric cars and light trucks sold or leased in the quarter. This data indicates that consumer demand for electric vehicles remains strong, even though the rapid growth seen in previous years has slowed down. Tesla's loss of market share highlights the increasing competition in the electric vehicle market that Tesla once dominated.
