Tesla reported Q2 earnings of 31 cents per share, missing Wall Street's expected 51 cents, and revenue of $28.23bn vs. $25.71bn forecast.
The stock fell over 3% in after-hours trading, adding to a year-to-date decline of about 14%.
Earnings were pressured by the end of U.S. EV tax subsidies and increased competition from cheaper Chinese automakers.
SpaceX's record stock market debut briefly made Elon Musk the world's first trillionaire, though his net worth has since fallen.
Tesla is shifting focus from vehicles to robotics (Optimus) and autonomous driving (Robotaxi), with Musk claiming Optimus could be 'the biggest product ever.'
Robotaxi service is expanding to Tampa and Orlando, but only about 50 vehicles operate in Austin, with rollout slowed by safety concerns.
Musk emphasized that scaling Robotaxi requires caution to avoid harm and negative regulatory attention.
