Tesla's autonomous Cybercab began operating in Texas after its September 3 unveiling in Austin, but the event failed to satisfy investors. Tesla shares fell 5.9% in the session after the presentation, erasing approximately $88 billion in market capitalization after a 5.4% rally beforehand. Shares were changing hands at $354.57 in Tuesday's premarket session, up 0.1%, while the investment community continued assessing the launch. The stock is down 21% year to date. The Cybercab operates without a conventional steering wheel or foot pedals, relying exclusively on optical camera technology. That camera-centric design could offer a cost advantage over systems using lidar and radar, but analysts questioned the limited information disclosed at the event. GLJ Research analyst Gordon Johnson cited Tesla's registration of only 45 vehicles, the absence of operational-unit figures, no livestream, Elon Musk's absence from the presentation stage, and the lack of pricing, per-mile cost projections, or a consumer ordering mechanism. He retains a Sell rating and a $24.86 target. Wells Fargo analyst Colin Langan also maintains a Sell rating, with a $130 target, saying the reveal lacked sufficient technical specifications and a concrete deployment schedule. Canaccord Genuity's George Ginarikas remains bullish with a Buy rating, calling the vehicle "slick" and "luminous" and describing it as representing "tomorrow's look," while noting that adequate geographic service density will be important for adoption. Tesla's August sales added to investor concerns. Estimated U.S. deliveries fell 26% year over year to 40,816 vehicles from 55,500, the company's sharpest monthly contraction in 2026 after declines of 20% in June and 21% in July. August deliveries in China dropped 12.4% to 50,047 vehicles, extending the decline to three consecutive months. Tesla has offered discounts of as much as 10,000 yuan, approximately $1,475, on Model Y inventory. European registrations rose 279% in France and 104% in Denmark but declined in Norway, Spain, Sweden, Portugal, and Italy. The National Highway Traffic Safety Administration, or NHTSA (U.S. auto safety regulator), has opened an audit of Tesla's self-certification process, which declared the Cybercab compliant with federal safety rules. The review focuses on its lack of conventional steering mechanisms and pedals, a configuration outside the established federal motor-vehicle safety framework, and remains unresolved. Tesla's second-quarter revenue rose 26% year over year to $28.24 billion, while operating margin narrowed to 1.4%. TipRanks gives TSLA a Moderate Buy consensus based on 11 Buy, 13 Hold, and three Sell recommendations, with an average price target of $377.08, implying 6.5% potential upside.
