Tesla to Double 2026 Capex to Over $20B, Betting Big on Robotaxis and Humanoid Robots

Tesla (TSLA-US) plans to more than double its 2026 capital expenditure to over $20 billion—double Wall Street’s $10B average estimate—with most funds redirected from legacy EV production toward unproven ventures: autonomous Cybercabs, Optimus humanoid robots, and battery materials infrastructure. CFO Vaibhav Taneja confirmed investments will prioritize facilities for driverless vehicles, the long-delayed Tesla Semi, and lithium refining. CEO Elon Musk announced discontinuation of Model S/X production in California to repurpose space for robot manufacturing, calling 2026 a “massive capex year” for an “epic future.” With $44B in cash, Tesla can self-fund this push, though debt may follow. Analysts at Zacks and REX Financial view the spend as essential to validate AI-driven growth narratives that underpin Tesla’s tech-like valuation, even as EV sales lag behind BYD.
