Tesla's auto sales have declined in recent years, with deliveries falling 9% in 2025 and 14% in Q1 2026. However, the company is betting its future on the emerging $10 trillion global robotaxi market, which Ark Invest believes could represent 90% of Tesla's enterprise value by 2029. Tesla's vertical integration and production capacity give it a scaling advantage to quickly deploy robotaxis, though Ark's aggressive $2,900 per share price target by 2029 may be overly optimistic given Elon Musk's history of missed timelines.

Why it matters

Tesla's shift away from relying on auto sales towards the robotaxi opportunity represents a major strategic pivot for the company. If successful, it could unlock massive growth potential, but the timeline and execution risks are significant. This story highlights the high-stakes gamble Tesla is making as it navigates a challenging EV market.

The details

Tesla's auto sales have declined in recent years, with deliveries falling 9% in 2025 and 14% in Q1 2026. In response, the company's profits were nearly cut in half in 2025. However, Tesla is betting its future on the emerging $10 trillion global robotaxi market. According to Ark Invest, Tesla's robotaxi business could represent around 90% of its enterprise value by 2029, as the company leverages its vertical integration and production capacity to quickly deploy autonomous vehicles. Ark believes Tesla could capture a significant share of this market, though the firm's aggressive $2,900 per share price target by 2029 may be overly optimistic given Elon Musk's history of missed timelines on autonomous driving promises.

  • In 2025, Tesla's auto deliveries fell by around 9%, nearly cutting the company's profits in half.
  • In Q1 2026, Tesla's vehicle deliveries dropped 14% from the previous quarter, though they did rise modestly year over year.
