Tesla, Inc.: A Sum-of-the-Parts (SOTP) Valuation and Scenario Analysis for 2028 Enterprise Value

I. Summary

This report begins with the premise that the enterprise value of Tesla, Inc. (hereafter Tesla) is composed of two disparate entities: a capital-intensive manufacturing business entering maturity (Automotive and Energy) and a high-risk, high-return technology venture portfolio (Autonomous Driving and Robotics). Therefore, a single, unified valuation model could distort Tesla’s intrinsic value, making it essential to apply a Sum-of-the-Parts (SOTP) valuation methodology to reflect the unique characteristics of each business segment.

In this analysis, a Discounted Cash Flow (DCF) model is applied to the mature business segments, while market-based and probability-weighted valuation models are used for the early-stage, high-growth venture businesses. Based on this SOTP framework, the enterprise value through 2028 is projected across Base, Bull, and Bear scenarios.

The results show a dramatic variation in Tesla’s enterprise value depending on the scenario. In the Bear scenario, Tesla’s value converges with that of a manufacturer, whereas in the Bull scenario, it demonstrates potential far exceeding its current value, driven by the commercial success of the Robotaxi and Optimus projects. This clearly indicates that the high volatility of Tesla’s stock stems from the uncertainty surrounding the success of its new technology ventures, which constitute the majority of its future value. Consequently, an investment in Tesla is not merely an investment in an electric vehicle manufacturer but a simultaneous bet on a portfolio of technologies at various venture capital stages.

II. Analysis of Tesla’s Core Businesses: Manufacturing-Based Valuation

This section establishes the baseline value of Tesla’s current revenue-generating business segments. These businesses form the company’s foundation but are gradually entering a mature growth phase, requiring a different valuation approach from the speculative venture businesses.

A. Automotive Business: At the Crossroads of Maturity and Competition

Current Status Analysis

Tesla’s automotive business still accounts for the largest portion of its revenue, but its growth is showing signs of slowing. Vehicle deliveries in Q2 2025 rebounded to 384,122 units from 336,681 in Q1, but this represented a year-over-year decline.¹ This suggests that demand saturation in key markets and intensifying competition are becoming a reality.⁴ Indeed, the automotive segment’s share of total revenue has decreased from 87.7% in 2022 to 78.9% in 2024, and it is projected to fall to 74% by 2025.⁷ This trend clearly illustrates Tesla’s strategic direction of transitioning from a simple automaker to a comprehensive technology company.

Future Growth Drivers and Challenges

In response to slowing demand, Tesla is preparing a lower-cost model utilizing the existing Model Y platform, targeted for a late 2025 launch.⁹ This is an essential strategy to defend market share amidst fierce competition from traditional automakers like Ford and GM, as well as emerging EV companies such as Rivian, Lucid, and especially China’s BYD.⁵ While the launch of a low-cost model will contribute to increasing sales volume, it will likely cause a decline in the Average Selling Price (ASP), putting additional pressure on the automotive segment’s gross profit margin, which currently stands at about 17%.¹²

This strategic move implies a shift in the role of the automotive business. Maintaining sales volume and expanding the size of the Tesla fleet on the road through low-cost models can be interpreted as part of a larger picture, aimed more at accelerating autonomous driving data collection and securing a potential customer base for the future Robotaxi business, rather than maximizing its own profitability. In other words, the importance of the automotive business as a ‘means’ to supply data for the AI business is gradually increasing.

Valuation Approach

The automotive business segment is valued using a five-year DCF model. Reflecting market maturation, the revenue growth rate is assumed to gradually decrease from an initial ~20% to a perpetual growth rate of 3%. The EBITDA margin is projected to stabilize at a slightly compressed level of 15-16%, considering the impact of intensified competition and the launch of low-cost models.¹⁴

B. Energy Business: The Undervalued Growth Engine

Explosive Growth and Profitability

Tesla’s energy business has achieved remarkable growth in recent years, emerging as a new core driver. The Energy Storage Systems (ESS) segment, in particular, recorded a high growth rate of 48% year-over-year by deploying 20 GWh in the first half of 2025 alone.¹⁵ Even more noteworthy is its profitability. In Q2 2025, the energy division’s gross profit margin surpassed 30%, making it the most profitable business segment in Tesla on a percentage basis.¹² As of the first half of 2025, the energy business generated 23% of the company’s total profit while accounting for only 12% of its total revenue, driving the overall profit structure of the company.¹⁵

Production Capacity Expansion

Tesla currently has an ESS production capacity of 20 GWh per quarter (80 GWh annually) through its Nevada and Shanghai Gigafactories and is pursuing the construction of a Houston Megafactory with an annual capacity of 50 GWh, targeted for operation by the end of 2026.¹⁵ This provides a clear roadmap for sustained high growth and market dominance in the coming years. The recently unveiled Megapack 3 further enhances product competitiveness by increasing energy density and reducing installation costs.¹⁶

The growth of the energy business, accompanied by predictable and high profitability, plays a crucial role in providing financial stability to Tesla as a whole. It functions as a stable source of cash flow that offsets the growth slowdown and margin pressure faced by the automotive business, as well as the uncertainty of the autonomous driving and robotics businesses, which require massive R&D investment. In other words, the success of the energy business is not just an additive factor to the company’s value; it serves as a financial ‘ballast’ that allows Tesla to invest boldly in high-risk technology ventures.

Valuation Approach

The energy business segment is valued through a separate DCF model. Reflecting explosive demand and production capacity expansion, the short-term revenue growth rate is set high at 40-50% annually, then assumed to gradually stabilize. The gross profit margin is assumed to be sustainable at the 25-30% level, considering recent high profitability.

III. Pillars of Future Value: Quantifying High-Risk Ventures

This section evaluates the value of not what Tesla is today, but what it could become in the future. The valuation methodologies used here explicitly incorporate the uncertainty of technological breakthroughs and their binary success potential.

A. Full Self-Driving (FSD) and Software: The Monetization Challenge

Current Adoption and Strategy

The take rate for FSD is high at 50-60% for premium vehicles like the Model S/X, but it remains in the 10% range for the entire fleet, including the Model 3/Y.¹⁷ A recent one-month free trial program in North America resulted in only about a 2% conversion rate to purchase or subscription, despite a price reduction to $8,000 and the launch of a $99/month subscription model.¹⁸ This demonstrates consumer skepticism about FSD’s current capabilities and high price sensitivity. Tesla’s decision to lower the FSD price itself signals a significant strategic shift.²⁰

This change in pricing policy indicates a shift in the center of gravity from short-term profit maximization to long-term data acquisition. An enormous amount of real-world driving data is essential to perfect Level 4/5 full autonomous driving technology.²² The low conversion rate implies that the previous high-price policy hindered the speed of data collection. Therefore, lowering the price and promoting the subscription model is a strategic decision to dramatically increase the number of FSD users and accelerate the data collection ‘flywheel,’ even at the cost of some short-term software revenue. This is a foundational move to increase the probability of realizing a multi-trillion-dollar Robotaxi network.

Valuation Approach

FSD is modeled by splitting its value into two parts, rather than being valued as an independent DCF entity.

1. Short-term Value: Valued as a high-margin software revenue stream generated by applying an estimated take rate (outright purchase + subscription conversion) to vehicle sales forecasts.
2. Long-term Strategic Value: The core value of FSD lies in its role as an ‘enabling technology’ for the Robotaxi network. This value is reflected by applying scenario-specific success probabilities in the valuation of the Robotaxi business in the next section.

B. Robotaxi Network: A Bet on Trillion-Dollar Value

Business Model and Timeline

Tesla began a limited Robotaxi service with 10 Model Y vehicles in Austin, Texas, in June 2025, with plans to open the service to the general public and expand to other cities.²³ The ultimate vision is to build a massive autonomous ride-hailing network composed of both Tesla-owned vehicles and vehicles contributed by individual owners. Some analysts, like ARK Invest, predict this business will account for the majority of Tesla’s future revenue.²⁶

Unit Economics

The estimated revenue per mile for a Robotaxi is between $1.46 and $2.00, with operating costs projected at around $0.50, suggesting very high profitability.²⁷ A single vehicle could generate significant annual revenue ²⁷, and the key variable for long-term profitability will be the ratio of vehicles to human teleoperators required for remote assistance.²⁹

A successful Robotaxi network does more than just create a new revenue stream; it forms a powerful virtuous cycle with the automotive business. The massive cash flow generated from the network would provide Tesla with the capital to mass-produce dedicated vehicles like the Cybercab and expand its self-owned fleet.⁹ Simultaneously, it offers a strong economic incentive for individual owners to participate in the network with their vehicles, thereby boosting consumer sales. This increased production volume, in turn, reduces the per-vehicle production cost according to Wright’s Law, which then enhances the economics of the Robotaxi network, creating a powerful flywheel effect.²⁶

Valuation Approach

The Robotaxi business is the most complex and critical part of the valuation. Its value is calculated using the following market model:

1. Estimate the Total Addressable Market (TAM) for the global ride-hailing service in 2028.
2. Forecast Tesla’s market share for each scenario (Base, Bull, Bear).
3. Calculate total revenue based on the number of operating vehicles, annual miles driven per vehicle, and revenue per mile.
4. Apply a high EBITDA margin of 50-60%, reflecting the nature of a software platform business.
5. Derive the enterprise value by applying a high valuation multiple (EV/EBITDA of 20-30x) typical for high-growth tech platforms.
6. Finally, apply a probability weight to the total value for each scenario (e.g., Bear 10%, Base 40%, Bull 70%) to reflect technological and regulatory risks.

C. Optimus Humanoid Robot: The Final Piece of the Puzzle

Timeline and Production Goals

Tesla’s humanoid robot, Optimus, is developing rapidly, having moved past the second-generation prototype to a finalized third-generation design.³⁰ Limited production is set to begin in 2025, with full-scale production targeted for 2026, and an ambitious plan to produce one million units annually within five years.³⁰

Market and Use Cases

Optimus is aimed at being a general-purpose robot, covering everything from industrial tasks like logistics and assembly in factories to domestic services such as household chores and assisting the elderly.³³ Elon Musk has estimated the potential value of this market at $10 trillion and claimed it will eventually account for about 80% of Tesla’s enterprise value.³⁴ In particular, setting a target sales price of $20,000-$30,000 is a revolutionary strategy that could disrupt the existing industrial robot market, where prices run into the hundreds of thousands of dollars.³³

The value of Optimus will first manifest as a cost-saving tool within Tesla, even before it generates direct revenue from external sales. The manufacturing process is labor-intensive, and labor costs are a major component of the Cost of Goods Sold (COGS). By initially deploying thousands of Optimus robots in its own factories to automate repetitive tasks like transporting parts and assisting with assembly, Tesla can dramatically reduce labor costs and directly improve the gross profit margins of its automotive and energy divisions.³³ The large-scale operational data gathered in this process will serve as an R&D testbed to improve and refine the product, which will minimize risks and maximize competitiveness before launching a commercialized product to the external market.

Valuation Approach

Valuing Optimus is similar to valuing a pre-revenue startup. A TAM-based approach is used:

1. Estimate the TAM for humanoid robots in the manufacturing and logistics sectors between 2030-2035.
2. Set Tesla’s expected market share for each scenario.
3. Calculate a future enterprise value based on potential future revenue and target profit margins.
4. Discount this future enterprise value back to a 2028 present value using a high discount rate of 30-40% to reflect extreme execution risk.
5. Apply a low probability weight of 10% in the Base scenario and a more meaningful weight of 40% in the Bull scenario. The value is assumed to be ‘0’ in the Bear scenario.

IV. Valuation Framework: Methodology and Key Assumptions

Rationale for SOTP Methodology

This report adopts the SOTP methodology for Tesla’s valuation.³⁷ This is because each of Tesla’s constituent business segments has fundamentally different risk profiles, growth trajectories, and capital requirements. The automotive and energy businesses exhibit characteristics of mature manufacturing, whereas autonomous driving and robotics are closer to venture capital-stage technology businesses. Valuing such heterogeneous businesses with a single Weighted Average Cost of Capital (WACC) and perpetual growth rate could distort the value of each segment and lead to a misjudgment of the entire company’s intrinsic value. SOTP minimizes this error by valuing each segment individually before summing them up, enabling a more precise valuation.

Global Assumptions

Each business segment’s DCF model applies unique assumptions for the discount rate (WACC), perpetual growth rate, and corporate tax rate.³⁸ A relatively low discount rate is applied to the mature automotive segment, while a medium-level discount rate is used for the high-growth energy segment. The values of future ventures like Robotaxi and Optimus are adjusted through high discount rates and probability weights to reflect their high uncertainty.

Scenario Definitions

This analysis establishes three scenarios to capture the key uncertainties related to technological development, regulatory approval, and market acceptance.

• Base Scenario: Assumes the most likely path, based on management guidance and market analyst consensus.
• Bull Scenario: Assumes technological and commercial goals are smoothly achieved, including the early completion of FSD technology, rapid expansion of the Robotaxi network, and successful commercialization of Optimus.
• Bear Scenario: Assumes challenges such as intensified competition, delays in autonomous driving technology development, regulatory hurdles, and failure to commercialize new businesses.

V. Quantitative Scenario Analysis: 2028 Tesla Market Cap Forecast

This section is the conclusion of the quantitative analysis, deriving Tesla’s projected 2028 market capitalization based on the framework and scenario-specific assumptions defined earlier.

A. Base Scenario: “Steady Progress”

In this scenario, Tesla continues to see stable growth in its core businesses and begins to show tangible results in its new ventures. By 2028, vehicle deliveries reach 3 million units, and energy storage deployments hit 120 GWh. The effective FSD subscription rate reaches 30%, generating steady software revenue. The Robotaxi network begins operations in major cities with a fleet of 100,000 vehicles, proving the business’s viability. Optimus is in its initial production phase, with 5,000 units sold for internal processes and to some B2B customers, but its impact on the overall enterprise value is still limited.

B. Bull Scenario: “Technological Utopia”

This scenario assumes that most of Tesla’s technological visions are realized. Driven by demand for low-cost models and Robotaxis, vehicle deliveries reach 5 million units in 2028. The energy business continues its explosive growth, deploying 200 GWh annually. As FSD technology matures, the effective subscription rate rises to 50%. The Robotaxi network successfully overcomes regulatory hurdles and rapidly expands to a global scale of 1 million vehicles, generating massive platform revenue. The Optimus robot also succeeds in commercialization, with 50,000 units sold annually, establishing itself as a new growth engine.

C. Bear Scenario: “Manufacturing Limitations”

This scenario assumes Tesla hits technological and regulatory walls and falls behind the competition. Vehicle deliveries stagnate at around 2 million units in 2028, and the growth of the energy business also slows. FSD remains a niche product, and the Robotaxi network is indefinitely postponed due to technical and legal issues. Optimus remains in the R&D project stage, creating no commercial value. In this case, Tesla’s value depends entirely on the performance of its two manufacturing segments: automotive and energy.

VI. Synthesis and Conclusion

The 2028 projected market capitalization for Tesla, derived from this SOTP analysis, shows an extreme variation, ranging from approximately $610 billion in the Bear scenario to about $5.45 trillion in the Bull scenario. This wide valuation spectrum provides a fundamental answer to why Tesla’s stock exhibits high volatility.⁴ The market is constantly pricing in not just current automotive sales performance, but also the probability of success for future technology ventures that could create immense value if successful, but also carry a high risk of failure.

Key Value Drivers and Risk Factors

The analysis summarizes the key drivers and risk factors that will determine Tesla’s future value as follows:

• Key Value Drivers:
  1. Successful implementation of Level 4/5 full autonomous driving technology: This is an absolute prerequisite for the commercial success of the Robotaxi network.
  2. Creation of a favorable regulatory environment for autonomous driving: As much as technological completion, regulatory approval from governments worldwide will determine the speed of the Robotaxi business expansion.
  3. Continued expansion of the high-margin energy storage business: This generates stable cash flow to support high-risk R&D investments.
  4. Successful mass production and commercialization of the Optimus robot: This holds the potential to elevate Tesla beyond the limits of a manufacturer to a new level of enterprise.
• Key Risk Factors:
  1. Intensifying competition in the EV market: There is a risk that margins in the automotive segment will be continuously pressured by the rise of existing and new competitors.⁵
  2. Delays or failure in autonomous driving technology development: This could nullify the largest value-appreciation scenario, the Robotaxi network.
  3. Strict government regulations: Stringent regulations on the operation of autonomous vehicles could act as a serious obstacle to business expansion.
  4. Key person risk: As the influence of CEO Elon Musk is absolute, his tenure or external activities could bring unexpected volatility to the company’s value.⁴

Final Conclusion

In conclusion, an investment in Tesla is not a bet on the single industry of electric vehicles. It is closer to a complex investment object where a single manufacturer is simultaneously pursuing and funding multiple technology projects at various venture capital stages. The final valuation presented in this report is less a result of precise calculation and more a probability-weighted assessment of the management’s ability to successfully lead a series of world-changing, yet extremely uncertain, technological breakthroughs.

The path to the Bull scenario is fraught with immense execution risk, and if Tesla fails to transition from a mere manufacturer to a technology platform company, the Bear scenario could become a reality, leading to a significant decline in value. Investors must closely monitor the progress of each business segment, especially the achievement of milestones in autonomous driving technology and changes in the regulatory environment, to continuously evaluate how the variables in this complex value equation are changing.
