Shares of Tesla have fallen nearly 25% in 2026.
Musk's company reported a record 480,126 deliveries in the second quarter.
It's been an interesting and mixed 2026 thus far for Tesla (NASDAQ: TSLA). While the stock has dropped almost 25% since January, the company's dominance in the U.S. electric vehicle (EV) market climbed to 59%, according to data from Cox Automotive. This is a level Elon Musk's company has not seen since 2023.
The rebound in market share tells an interesting story for Tesla, which has battled an increasingly competitive yet challenging landscape, the expiration of the federal EV tax credit, and Musk's public image, which has hurt the brand. The overall American appetite for EVs has stalled, and legacy automakers have shifted gears back to gas-powered vehicles. The market-share dominance is both a sign of that retreat and of Tesla's competitive edge against pure-play rivals.

While the market share story is positive, there are still plenty of obstacles ahead for Tesla. The company's revenue increased 26% on a record number of deliveries, but profitability decreased. In fact, free cash flow turned negative as Tesla increased its funding of other ambitions, including artificial intelligence, Optimus, and robotaxis.

This is a familiar conundrum for Tesla investors. The company remains a top player in the global electric vehicle market. Yet the investments in speculative ancillary businesses hurt margins and make investors nervous.
Tesla's core business remains strong even as BYD, Rivian, and other rivals intensify competition globally. What Tesla needs in the long run is for one of its other big bets, be it autonomous driving or robotics, to pay off, thereby justifying the increased pressure on the balance sheet and income statements. Until then, Tesla remains a wild card. It trades at a hefty premium as it shifts its priorities. Longtime investors have done well, but those looking to get in now should expect continued volatility as Tesla's AI projects iterate.
There's still potential upside, but also plenty of risk.
