The Latest U.S. EV Sales Data and What They Mean for Tesla
The Cox Automotive/Kelley Blue Book Q1 2026 EV Sales Report is out, and makes for mixed reading for Tesla in the U.S. On balance, it’s a net positive for the company, as it builds on the theme established in the previous quarter. In other words, while the whole of the industry is suffering the after-effects of the expiry of the $7,500 new clean vehicle credit and the $4,000 used electric vehicle (EV) credit at the end of September 2025.
The end of these credits caused many buyers to move up their EV purchases, leading to a sharp drop in sales in the fourth quarter of 2025. This decline continued into the first quarter of 2026.
Tesla held up relatively well
That said, Tesla’s EV sales were down only 8.4% year over year in the first quarter, compared to a 27% decline for the overall U.S. EV industry. Of course, part of that reflects an easier comparison with Model Y sales in last year’s first quarter, given weak sales due to the impending release of a new Model Y in the Spring of 2025.
In fact, Model Y sales rose 22.7% year-over-year in the U.S. in the first quarter. However. Model S sales declined a disappointing 39.7% in the first quarter, resulting in the mixed result I referred to earlier.
What it means for the investment case for Tesla stock
According to the data, Tesla’s EV market share in the U.S. was 58.9% in the fourth quarter and 54.2% in the first quarter. While these figures will bounce around a bit depending on various factors (including rivals releasing loss-making models), the narrative that Tesla’s market position is under serious threat from all-conquering new EVs doesn’t add up.
Moreover, with its rivals discontinuing investment in, effectively, subsidized EVs, the cost to the company of regaining market share is clearer. The more debatable point is why Model 3 sales aren’t picking up with the release of cheaper, standard models. That’s something to look out for in future quarters.
