Tesla shares rose 18.2% in August to finish at $357.01 as investors responded to developments involving the company’s robotaxi (autonomous ride-hailing vehicle) program. Nevada regulators expanded Clark County’s Cybercab authorization from 10 to 5,000 vehicles, while Tesla registered 45 Cybercab vehicles in Texas ahead of an Austin launch. The company also reported favorable mid-August safety data from its Cybercab unveiling, although the sample was smaller than Waymo’s. Tesla’s second-quarter revenue rose 25.5% year over year to $28.24 billion, exceeding the $26.42 billion analyst estimate, while earnings per share of $0.33 missed the $0.50 forecast. Higher spending on autonomous vehicles, the Optimus humanoid robot, artificial intelligence and vehicle discounts contributed to a 3.67% net profit margin. Only six municipalities currently have fully unsupervised robotaxi services operating in 2026, below CEO Elon Musk’s January projection of operations in dozens of major cities by year-end. Analysts retain a Hold consensus and a $401.74 price target, while institutional investors own 66.2% of outstanding shares.
