Tesla market share (electric vehicle market) in the United States fall to new lows in August, according to data from research firm Cox Automotive.
The decline comes amid a surge in electric vehicle sales in the U.S. after the federal tax credit expired. Tesla's global sales have been falling since their peak in 2023. After a small 1% drop in 2024, Tesla's sales are down about 10% globally in 2025.The American automaker's sales in Europe have fallen by as much as 40%, while in China, the world's largest electric vehicle market, Tesla has seen a decline of about 6%.

In its home market, the US, Tesla appears to be maintaining its sales momentum, but that is not expected to last. Electric vehicle sales are expected to reach record levels in the third quarter of 2025 in the US, due to the expiration of the $7,500 tax credit for electric vehicles (expires September 30). This drives demand forward into the third quarter, with sales expected to collapse in the fourth quarter.
Every electric vehicle maker is competing for strong demand before the end of the tax credit, and new data suggests Tesla may be losing market share in the process. According to new data from Cox Automotive, Tesla’s U.S. market share fell to 38% in August. Tesla, which once held more than 80% of the U.S. electric vehicle market, fell to 38% last month. It’s the first time it’s fallen below 40% since October 2017.
While it’s been a while since Tesla dominated the electric vehicle market, the Texas-based company has held a market share above 50% for many years. Tesla has begun to lose its dominance in the U.S. market this year, with its market share steadily declining throughout the year. By June, Tesla’s market share had fallen below 50% to 48.7%. Since then, it has fallen to 42% in July and now to 38% in August.

The expectation was that Tesla’s market share would decline over time as more electric vehicles became available. Tesla’s decline in market share is not just a business statistic; it is a sign that the electric vehicle market is now entering a phase of maturity. The period in which Tesla enjoyed a near-monopoly presence is over, as traditional manufacturers such as Ford, GM and Volkswagen, as well as newer players, now offer worthy alternatives at all price points. This means that the consumer has choices and does not have to turn exclusively to Tesla to acquire an electric vehicle.
Tesla's biggest weakness today is its limited number of models and slow renewal of its portfolio. While competitors are launching SUVs, pickup trucks and affordable compact EVs, Tesla still relies on a few product lines that have been in the market for years. In this context, the decline in share is not only a matter of external competition, but also a lack of differentiation and adaptation.

Strategically, the company is at a critical crossroads. If it doesn’t invest in new, more affordable, and more diverse models, it will see its market share shrink further. The short-term success it may experience from the tax credit won’t change the long-term picture. Competition is no longer an isolated threat, but a fully-fledged ecosystem that is forcing Tesla to evolve or lose its lead forever.
