Tesla (TSLA@US) remains the top-selling electric vehicle in the U.S. market, but it is losing its position as more affordable models are on the rise. As options for EVs below $50,000, Tesla competitors are reaching a market where “Tesla does not yet truly compete.” S&P Global Mobility reported that Tesla’s market share was at 65 percent through the third quarter, down from 71 percent last year and 79 percent in 2020. The firm forecast that its market share will decline to less than 20 percent by 2025.
