To The Moon

Tesla rose 5.21% on Monday while SPCX slipped 0.40%. The divergence highlights how investors are positioning themselves around different growth opportunities, with Tesla attracting attention for its potential in autonomous driving, AI and robotics.

One of the boldest long-term forecasts comes from ARK Invest, which has modelled a Tesla share price of approximately $4,400 by 2031, with around 80% of enterprise value attributed to Robotaxi in that scenario.

That valuation depends on a major transformation. Tesla would need to evolve beyond selling vehicles and establish a scalable autonomous ride-hailing business capable of generating substantial recurring revenue.

The opportunity is significant, but so is the execution challenge.

1. The first test: Can Tesla scale paid Robotaxi rides?

A successful demonstration can attract attention, but a sustainable business requires consistent commercial demand.

Investors should watch the number of vehicles operating commercially, the number of paid rides completed, repeat customer usage and the pace of geographic expansion.

Growing ride volumes would be encouraging, but the quality of that growth matters too. A service that attracts customers only through introductory pricing or operates in a limited area may not be enough to support aggressive long-term assumptions.

The key question is whether Tesla can expand its service while maintaining safety, reliability and customer demand.

2. The bigger question: Can each vehicle generate attractive returns?

Revenue growth alone will not prove the Robotaxi business model works.

Tesla would need to cover the costs of deploying and maintaining vehicles, charging, insurance, cleaning, repairs, fleet management and any remote human assistance required. Regulatory compliance and the cost of developing autonomous-driving technology also matter.

One useful measure would be revenue and operating profit per vehicle.

If each vehicle can complete more paid rides and generate higher earnings without a proportionate increase in costs, the business could benefit from economies of scale.

However, if vehicles spend too much time idle, operating costs remain high or human intervention is frequently required, profitability could take longer to achieve.

The milestone to watch is not simply more Robotaxis on the road, but improving economics per vehicle.

3. Regulation and safety could determine the speed of expansion

Autonomous driving offers the possibility of reducing the need for a human driver, but commercial deployment depends on more than technology.

Tesla must demonstrate reliable performance in real-world conditions and meet the regulatory requirements of each market in which it operates.

A successful rollout in one location does not automatically guarantee approval or equivalent performance elsewhere. Different road conditions, traffic patterns and regulatory standards can complicate expansion.

Investors should therefore distinguish between a limited service launch and evidence that Tesla can operate commercially across a growing number of markets.

4. Can Robotaxi support Tesla’s AI and robotics ambitions?

Tesla’s longer-term vision extends beyond autonomous transport. The company is also investing in AI infrastructure and its Optimus humanoid robot programme.

Bulls argue that a profitable Robotaxi network could eventually generate recurring cash flow to support these initiatives. A large fleet could also provide operating data that helps improve autonomous-driving capabilities.

But there is a financial trade-off.

Tesla must spend money developing technology and deploying vehicles before it can establish the full commercial returns. If the Robotaxi business takes longer than expected to become profitable, continued investment could place pressure on cash flow.

Investors need to assess whether Tesla can finance its ambitions while maintaining a sustainable balance between capital expenditure and cash generation.

5. What would justify the long-term bull case?

ARK’s approximately $4,400 share-price target for 2031 is an ambitious scenario, not a guaranteed outcome. With around 80% of enterprise value in that model attributed to Robotaxi, the assumptions behind autonomous driving become particularly important.

The strongest evidence would be a combination of:

• Commercial scale: Paid rides and active vehicles increase consistently.

• Improving unit economics: Revenue and profit per vehicle improve as utilisation rises.

• Operational reliability: Safety performance supports expansion into additional markets.

• Positive cash generation: Robotaxi begins contributing meaningful operating profit without requiring ever-increasing investment.

Until these indicators become clearer, a large portion of the bull case remains dependent on future execution rather than an established earnings stream.

My takeaway

Tesla’s Robotaxi opportunity could eventually change how the market values the company. However, technological potential and commercial profitability are two different things.

The next major catalyst may not be another ambitious forecast or product announcement. It may be hard operating data showing how many paid rides Tesla can deliver, how much profit each vehicle generates and how quickly the business can expand.

For Tesla’s valuation to become more convincing, Robotaxi needs to progress from a long-term growth promise to a measurable contributor to earnings and cash flow.
