Tesla's electric vehicle sales have been declining, but the company's bets on robotaxis and humanoid robots could provide a major boost to its stock price in the long run. Cathie Wood's Ark Investment Management believes Tesla has the production capacity to build fleets of robotaxis, while CEO Elon Musk has said the company's Optimus humanoid robots could add $20 trillion to Tesla's market cap over time. However, Tesla needs to deliver on these technologies and drive down costs for widespread adoption.

Why it matters

Tesla's valuation remains high despite declining EV sales, suggesting investors are betting on the company's ability to disrupt the transportation and robotics industries. If Tesla can successfully develop and deploy robotaxis and humanoid robots, it could unlock significant long-term growth and justify the stock's premium valuation.

The details

Tesla's recently unveiled 2025 sales targets indicate its Cybertruck sales tumbled 48% year over year, while the S, X, and Y models also experienced volume dips. Only the Model 3 posted an annual sales increase, and it was just 1.3%. However, Tesla bulls are excited about the company's potential in robotaxis and humanoid robots. Ark Investment Management believes Tesla has the production capacity to build fleets of robotaxis, while Elon Musk has said the company's Optimus humanoid robots could add $20 trillion to Tesla's market cap over time. For these bets to pay off, Tesla needs to expand into new cities, remove human 'failsafe' drivers from robotaxis, and drive down costs for its Optimus robots.

  • Tesla unveiled its 2025 sales targets in Q3 2026.
  • Alphabet's Waymo is currently taking market share from Uber Technologies in San Francisco.
