One Wall Street Analyst Just Said Tesla Stock Could Be Worth $840: Time to Buy?

Morgan Stanley raised Tesla's bull-case price target by 2.4% to $840, while retaining an equal-weight rating and a $400 base-case target versus a share price of about $357. The long-term upside case includes more than 80,000 autonomous Tesla Semi trucks by 2040, potentially generating over $17B in high-margin annual FSD revenue at up to $18,000 per truck per month. Near-term contribution remains limited: Tesla expects Semi volumes to stay small while prioritizing passenger-vehicle and Cybercab FSD development, and execution depends on regulatory approvals, autonomy progress, and fleet adoption.

Analysis

The incremental bull-case change is not investable in isolation: it leaves a very wide gap between the central valuation framework and the upside narrative. More importantly, the implied autonomous-trucking software economics require fleets to surrender a material portion of the labor-cost savings to Tesla. At $216,000 per truck annually, the software take rate would need to be justified by verified driverless operation, insurance/liability allocation, and near-continuous utilization—not simply lower electric fuel and maintenance costs.

Near term, Semi is more likely to affect sentiment than earnings. A fleet pilot can validate total cost of ownership, but it does not establish scalable manufacturing yields, depot-charging economics, residual values, or regulatory approval across freight corridors. The six-month prioritization of passenger-vehicle autonomy pushes the next credible Semi-specific catalyst into 2027; until then, higher estimates risk being capitalized into TSLA's multiple without corresponding delivery or margin evidence.

The second-order beneficiaries of electrified heavy trucking are likely established truck OEMs and charging/power-equipment suppliers if fleet adoption is driven by TCO rather than proprietary autonomy. PCAR, DTG.DE and VOLV-B.ST have dealer, service, and fleet-financing moats that Tesla must replicate; PEP is a useful operational datapoint but not a material earnings beneficiary. Contrarian view: successful electric-Semi adoption could validate the category while narrowing Tesla's differentiation if autonomous functionality remains geographically constrained or requires safety operators.

The key falsifier for the bearish valuation view is independently reported driver-out commercial operation with fleet-level utilization and a disclosed software attach rate above $5,000 per vehicle per month. Conversely, production below the market's ramp expectations, negative gross-margin disclosure, or a regulatory/safety setback would expose how little of the long-duration software value is presently de-risked.

Key Decisions for Investors

• Do not add directional TSLA exposure on the analyst-target revision. Treat any rally unaccompanied by Semi production guidance, third-party fleet orders, or audited operating-cost data as multiple expansion rather than an earnings revision; reassess at the next earnings call and 2027 production update.
• For a 6-12 month relative-value expression, consider long PCAR / short TSLA in equal beta-adjusted dollars. PCAR captures electrification demand with an existing service and financing ecosystem, while TSLA carries the autonomy execution premium; target 15-20% spread return, stop if TSLA provides credible driver-out freight deployment or PCAR guides to material North American margin erosion.
• For TSLA holders, use 9-12 month put spreads following strength toward the $400 base-case reference level rather than outright shorting: buy the $400 put and sell a $300 put. The structure monetizes a reset toward the lower end of the current valuation range while limiting premium outlay if autonomy enthusiasm persists.
• Maintain a watch item on PEP fleet disclosures and California/Texas autonomous-trucking permits. A disclosed multi-year order with utilization, charging-cost, and maintenance data is the required confirmation before underwriting a broader truck-OEM or charging-infrastructure long.
