Tesla Controls 59% of the U.S. EV Market -- Its Highest Share Since 2023

TSLA reclaimed 59% of the U.S. electric vehicle market, its highest share since 2023, even as the stock has fallen nearly 25% in 2026. The company posted record deliveries and 26% revenue growth, though profitability contracted and free cash flow turned negative as Tesla pours capital into AI development, its Optimus humanoid robot, and robotaxi infrastructure.

The market-share gain comes despite intensifying competition from BYDDY and RIVN. Tesla's valuation now hinges on speculative ventures in autonomous driving and robotics rather than its core automotive margins, which are under pressure from the heavy investment cycle.

The divergence between operational momentum—record deliveries and dominant market position—and financial performance signals Tesla is trading execution today for optionality tomorrow. Free cash flow negativity marks a shift from the cash-generative profile that supported the stock through prior rallies.
