Morgan Stanley has raised its optimistic scenario valuation for Tesla stock, lifting its “bull case” price target to $840 per share from $820, citing the growing earnings potential of the company’s Semi electric truck and autonomous trucking business. The adjustment, led by analyst Andrew Percoco, reflects a view that Tesla’s commercial vehicle ambitions are being undervalued by the market.
The development has drawn attention because it frames a potential pathway for Tesla to generate substantial recurring software revenue from autonomous freight operations—a business model that could, over time, reshape how investors value the company. However, it is important to understand that the $840 figure represents Morgan Stanley’s bull-case scenario, not its base-case valuation. The firm maintained its Equal Weight rating and a $400 base-case price target on Tesla shares.
Morgan Stanley’s $840 Bull Case: What It Actually Means
In financial analysis, a “bull case” describes an optimistic scenario in which a company performs better than expected across key business drivers. It is not a prediction of what will happen, but rather an exploration of what could happen if favorable conditions align.
Morgan Stanley raised its Tesla bull-case target by $20 per share, from $820 to $840. That adjustment was tied specifically to the potential value of the Semi and autonomous trucking business. According to the firm, the Semi opportunity alone could add roughly $80 billion in market value, equivalent to about $20 per share in the bull case.
The distinction between a bull-case target and a base-case target matters enormously for investors. Morgan Stanley’s $400 base-case target represents its central expectation for Tesla’s valuation under more moderate assumptions. The $840 bull-case target, by contrast, assumes that several high-stakes, long-term initiatives succeed on a large scale.
As of September 11, 2026, Tesla shares closed at $365.44. From that price, the $840 bull-case target would represent potential upside of approximately 130%. But that figure should be understood as a scenario calculation, not a forecast.
Why Tesla Semi Is Central to the Thesis
The Tesla Semi is an all-electric Class 8 heavy-duty truck designed for long-haul freight operations. Tesla first unveiled the vehicle in 2017 and began limited deliveries to customers like PepsiCo in late 2022. The company said in April 2026 that the first Semi had rolled off a high-volume production line in Nevada, though its July shareholder update only reaffirmed that production would begin in 2026 while removing an earlier forecast for volume production that year.
The truck’s appeal rests on several economic factors. Electric drivetrains have lower fuel and maintenance costs than diesel engines. Tesla’s Megacharger network, which can deliver up to 800 kilowatts, allows the Semi to recover about 60% of its range in 30 minutes. For fleet operators managing tight delivery schedules, those operational characteristics matter.
Morgan Stanley’s analysts have highlighted that diesel prices at $6 per gallon strengthen the economic case for electric trucking. The firm estimates that autonomous electric trucks could reduce fleet costs by roughly 20% compared to human-driven diesel trucks, primarily through lower labor, fuel, and insurance expenses.
Tesla has also announced plans to bring the Semi to Europe, with customer deliveries scheduled to begin in 2027. The European version will offer approximately 550 kilometers of range at a gross combination weight of 40 tonnes and energy consumption of about 1 kilowatt-hour per kilometer.
Tesla Semi and Autonomous Trucking: The Real Prize
The most significant aspect of Morgan Stanley’s thesis involves autonomy. Percoco describes the Tesla Semi as an “underappreciated driver of earnings growth through 2040,” and the numbers behind that view are striking.
Once fully autonomous, Morgan Stanley estimates Tesla could charge between $0.85 and $1.00 per mile in Full Self-Driving subscription fees for the Semi. That translates to $12,000 to $18,000 per month for each operational truck. For context, the firm forecasts only about $100 per month in FSD revenue for consumer vehicles—meaning the Semi opportunity is an order of magnitude larger on a per-unit basis.
Percoco called this difference “the most important takeaway of this note for a Tesla investor.”
Morgan Stanley’s model assumes Tesla could have 82,000 Semis on the road by 2040. At the estimated software fee range, that fleet would generate roughly $17 billion in annual FSD subscription revenue and an incremental $7.5 billion in earnings before interest and taxes. Those figures do not include revenue from truck sales or charging fees.
The firm also estimates that an autonomous electric truck could generate around $202,000 in annual profit for an operator, compared with nearly $37,000 for a human-driven diesel truck. That model assumes each autonomous truck travels 18,000 miles per month, more than double typical industry utilization.
The Software Revenue Thesis: Why It Matters
To understand why Morgan Stanley believes the Semi could meaningfully change Tesla’s valuation, it helps to understand how investors think about different types of revenue.
Vehicle sales are generally “one-time” transactions. Tesla sells a truck, recognizes the revenue, and the transaction is largely complete. Software subscriptions, by contrast, generate recurring revenue that continues month after month for as long as the customer uses the product. Recurring revenue streams are often valued more highly by investors because they are more predictable and can scale without proportional increases in cost.
Morgan Stanley’s thesis suggests that if Tesla can successfully deploy autonomous driving technology on the Semi, each truck could become a recurring revenue generator through FSD subscriptions. At $12,000 to $18,000 per month per truck, even a relatively small number of autonomous Semis could materially affect Tesla’s financial results. As Percoco noted, “small volumes can move numbers.”
However, this revenue is entirely dependent on Tesla achieving fully autonomous operation at scale—a technical and regulatory milestone that has not yet been reached. Current FSD capabilities require human supervision, and fully autonomous trucking would require both technological maturity and regulatory approval in each jurisdiction where it operates.
Tesla’s Business Beyond Electric Cars
The Semi story is part of a broader narrative that has shaped Tesla’s valuation for years: the idea that Tesla is not simply an automaker but a technology company with multiple potential revenue streams.
Tesla’s existing businesses include electric passenger vehicles, energy storage and solar products, and its Supercharger network. The company has also invested heavily in artificial intelligence and autonomous driving research. Its Optimus humanoid robot program and Robotaxi initiative represent additional long-term bets.
For investors focused on the Semi and autonomous trucking, the key question is whether Tesla can translate its technological investments into commercial products that generate meaningful revenue. Morgan Stanley’s bull case assumes that it can. The base case appears to assign less value to these unproven businesses.
Tesla’s second-quarter 2026 results illustrate the tension in the current business. Revenue came in at $28.24 billion, up 26% year-over-year and ahead of expectations. Vehicle deliveries reached 480,126 units, a record for a second quarter. But profitability weakened significantly. Operating margin fell to 1.4% from 4.1% a year earlier, and adjusted earnings per share of $0.33 missed analyst estimates of $0.53.
That divergence—strong revenue growth alongside declining margins—helps explain why analysts have different views on Tesla’s appropriate valuation. The bull case rests on future businesses becoming major profit drivers. The base case reflects more immediate concerns about automotive profitability.
Bull Case vs. Base Case: A Clear Comparison
Morgan Stanley’s two scenarios represent fundamentally different views of Tesla’s future.
Bull Case ($840)
The bull case assumes that Tesla’s autonomous trucking business becomes commercially successful at scale. Semi adoption accelerates, FSD software generates substantial recurring revenue, and margins improve as high-margin software revenue becomes a larger share of the business. Other AI and autonomy initiatives also contribute positively. Under these conditions, investors would likely assign a higher valuation multiple to Tesla’s earnings and revenue.
Base Case ($400)
The base case reflects more conservative assumptions. Vehicle demand grows but faces competition and potential margin pressure. Autonomous driving progress is slower, and software revenue remains limited. Execution risks, regulatory uncertainty, and production challenges weigh on results. The valuation reflects Tesla’s current business mix more than its speculative future opportunities.
Morgan Stanley’s Equal Weight rating indicates that, on balance, the firm views Tesla’s risk-reward as balanced at current levels. The bull case represents upside potential, not the central expectation.
Risks to the $840 Tesla Bull Case
The bull case depends on multiple things going right. Several risks could prevent it from materializing.
Autonomous driving risk. Fully autonomous trucking remains a technological challenge. Tesla’s FSD system currently requires human supervision. Achieving the level of reliability needed for driverless commercial operations could take years longer than optimists expect.
Regulatory risk. Autonomous trucking operates under a patchwork of regulations that vary by state and country. Widespread deployment would require regulatory approval in each jurisdiction, a process that could be slow and uncertain.
Production risk. Tesla must successfully scale Semi production. The company has a history of production delays, and the Semi has already experienced repeated timeline shifts. Morgan Stanley’s bull case assumes 82,000 Semis on the road by 2040, but that outcome depends on manufacturing execution.
Competition. Tesla faces competition from established truck manufacturers like Daimler, Volvo, and Traton, as well as emerging electric truck startups. Several competitors already sell battery-powered heavy-duty trucks in Europe and North America.
Valuation risk. Tesla’s stock already carries a valuation that reflects substantial future growth expectations. Even the base-case target of $400 implies a valuation that many traditional automakers do not command. If growth disappoints, the stock could face pressure.
Execution risk. The bull case requires success across multiple fronts simultaneously—Semi production, FSD development, regulatory approval, and software monetization. Failure in any one area could undermine the thesis.
Demand risk. Commercial fleet operators may adopt electric trucks more slowly than expected. Factors like charging infrastructure availability, route suitability, and upfront costs could slow adoption.
These risks do not mean the bull case is wrong. They mean it is a scenario that depends on favorable outcomes, not a baseline expectation.
Tesla Semi vs. Traditional Diesel Trucks
The economic case for electric trucking depends on a complex set of factors that vary by fleet and route.
Electric trucks offer lower fuel costs per mile than diesel, but the advantage depends on electricity rates relative to diesel prices. With diesel at $6 per gallon, the fuel cost differential is larger than it would be at $3 per gallon.
Maintenance costs also tend to be lower for electric drivetrains, which have fewer moving parts than diesel engines. However, electric trucks carry higher upfront purchase prices, and the total cost of ownership depends on how intensively the truck is used.
Charging infrastructure is another variable. Tesla’s Megacharger network provides high-speed charging, but its coverage is still limited compared to the ubiquitous diesel refueling network. Fleet operators must plan routes around charging availability.
Autonomous operation could change the economics further by reducing or eliminating driver labor costs, which represent a significant portion of trucking operating expenses. However, autonomous trucking also requires investment in sensor suites, computing hardware, and software.
Morgan Stanley’s model assumes autonomous electric trucks achieve 2.3 times better utilization than human-driven trucks, meaning they can operate more hours per day because they do not need to stop for driver rest breaks. That higher utilization spreads fixed costs over more miles, improving unit economics.
What $840 Would Mean for Tesla Investors
From Tesla’s closing price of $365.44 on September 11, 2026, the $840 bull-case target represents approximately 130% upside.
The calculation is straightforward:
Potential upside = ($840 − $365.44) ÷ $365.44 × 100 = 129.9%
That figure illustrates the magnitude of the scenario Morgan Stanley is contemplating. It also underscores why the bull case is described as a scenario rather than a forecast. A 130% return would require Tesla to execute successfully on multiple long-term initiatives simultaneously.
For context, Morgan Stanley’s $400 base-case target represents approximately 9.5% upside from the September 11 closing price.
What Investors Should Consider
This article does not provide personalized investment advice. Investors evaluating Tesla should consider several factors.
Valuation. Tesla trades at a significant premium to traditional automakers on most metrics. That premium reflects expectations for growth in autonomy, software, and energy. If those expectations moderate, the valuation could compress.
Growth assumptions. The bull case depends on assumptions about Semi adoption, FSD pricing, regulatory approval, and production execution. Investors should assess whether those assumptions seem reasonable given Tesla’s track record and competitive dynamics.
Risk tolerance. Tesla stock has historically experienced significant volatility. Investors uncomfortable with sharp price swings may find it unsuitable.
Execution. Tesla’s ability to deliver on production targets, achieve autonomy milestones, and monetize software will determine whether the bull case gains credibility over time.
Competition. The electric truck and autonomous driving markets are becoming more crowded. Tesla’s competitive position is not guaranteed.
Broader market conditions. Tesla’s stock is sensitive to interest rates, economic conditions, and investor sentiment toward growth stocks.
Tesla Stock Outlook: Three Scenarios
Bull Scenario
For the $840 case to become more plausible, Tesla would need to demonstrate meaningful progress on Semi production and deliveries, achieve regulatory approval for autonomous trucking in key markets, and show evidence that FSD subscription revenue can scale. Strong execution across these areas would build confidence in the long-term earnings potential Morgan Stanley describes.
Base Scenario
If Tesla’s growth progresses more moderately—Semi production ramps gradually, autonomy development takes time, and automotive margins stabilize—the $400 base-case target becomes the more relevant reference point. Tesla would remain a significant player in electric vehicles and energy, but the transformative software revenue scenario would remain speculative.
Bear Scenario
If Semi adoption disappoints, autonomy timelines slip further, automotive margins weaken, or competition intensifies, the stock could face pressure. A bear scenario might involve valuation contraction as investors reassess growth expectations. No specific bear-case numerical target is available from the source material, and inventing one would be inappropriate.
Tesla Semi Production and Delivery Outlook
Tesla has said it aims to manufacture 50,000 Semi trucks per year, though this represents a long-term goal rather than current output. The company began high-volume production in Nevada in 2026, and customer deliveries are expected to ramp gradually.
In Europe, Tesla plans to begin customer deliveries in 2027. The European version offers approximately 550 kilometers of range and supports both Megacharger and slower Basecharger options for depot charging.
These are announced plans and targets. Actual production and delivery figures will depend on manufacturing execution, supply chain readiness, and customer adoption.
Morgan Stanley’s View vs. Other Analysts
Morgan Stanley’s $840 bull-case target and $400 base-case target reflect a notable divergence. The bull case is significantly more optimistic than the base case, indicating that the firm sees substantial upside if certain conditions are met but is not yet convinced those conditions will be met.
The firm maintained its Equal Weight rating, which typically indicates a view that the stock is fairly valued relative to risk. That rating, combined with the wide gap between bull and base cases, suggests Morgan Stanley views Tesla as a stock with meaningful upside potential but also significant uncertainty.
Other analysts hold a range of views on Tesla, reflecting disagreement about the company’s growth prospects and appropriate valuation. The divergence between bull-case and base-case scenarios is not unique to Morgan Stanley; it reflects broader debate about how to value a company whose future may look very different from its present.
Why Tesla’s Software Business Matters
The appeal of software revenue to investors lies in its economics. Software can scale without proportional cost increases. Once developed, additional users can be added at relatively low marginal cost. Subscription models create recurring revenue that is more predictable than one-time sales.
If Tesla can charge $12,000 to $18,000 per month per autonomous Semi for FSD, that revenue would carry high margins and accumulate over time. Even a modest number of trucks could generate meaningful revenue. As the fleet grows, the software revenue stream would compound.
However, this revenue depends on Tesla achieving fully autonomous operation—a milestone that remains unproven. Current FSD requires human supervision, and regulatory approval for driverless operation is not guaranteed.
Tesla Stock and the Future of Autonomous Trucking
Autonomous trucking represents a significant potential market for Tesla and its competitors. The trucking industry faces persistent driver shortages and rising labor costs. Autonomous technology could address both challenges by reducing the need for human drivers and allowing trucks to operate more hours per day.
Several companies are pursuing autonomous trucking, including established truck manufacturers, technology startups, and logistics companies. Tesla’s advantage lies in its integrated approach—combining electric powertrains, battery technology, charging infrastructure, and autonomous driving software in a single platform.
Whether Tesla can translate that potential into commercial success remains to be seen. Morgan Stanley’s bull case assumes it can. The base case assumes the path will be longer and less certain.
