Tesla is building a mutually reinforcing growth strategy around Robotaxi and Optimus. The commercialization of Robotaxi serves as the most significant near-term catalyst for the stock price this year, while Optimus represents the company's long-term wager on transitioning into a physical AI entity. These two pillars together form what Morgan Stanley refers to as Tesla's "flywheel."
According to sources, Morgan Stanley analyst Andrew S. Percoco expressed being "incrementally more optimistic" about Robotaxi's commercial prospects after attending a San Francisco TMT conference and conducting an on-site visit to the Texas Gigafactory. He gave positive remarks regarding the company's progress in addressing edge cases, such as passenger pick-up and drop-off. The report maintained an Equal-weight rating on Tesla with a $415 price target, confirming the Cybercab mass production schedule to commence in April 2026.
Morgan Stanley's "Robotaxi flywheel" thesis posits that every mile of data accumulated by unsupervised Robotaxis will continuously enhance the underlying autonomous driving model. This, in turn, accelerates the progression towards unsupervised Full Self-Driving (FSD) for personal vehicles, boosting FSD adoption rates, improving automotive demand, and fueling free cash flow growth. Consequently, successful Robotaxi commercialization is not merely a source of mobility service revenue but also a critical lever for revitalizing the core automotive business.
However, this strategic layout comes with significant short-term financial pressure. Morgan Stanley anticipates Tesla's capital expenditure will surpass $20 billion in 2026, more than doubling year-over-year, leading to an estimated free cash flow deficit of approximately $8 billion. While Tesla's cash reserves of around $44 billion provide a near-term buffer, the firm does not rule out the possibility of Tesla seeking opportunistic financing in 2027 if the automotive business recovery falls short of expectations.
In Tesla's current Robotaxi deployment, the San Francisco Bay Area has hundreds of vehicles, but California regulations still require a safety monitor in the driver's seat. Therefore, Austin is the primary testing ground for true unsupervised deployment. Morgan Stanley estimates Tesla's Robotaxi fleet could reach roughly 1,500 vehicles by the end of 2026. Tesla is intentionally progressing slowly in Austin to refine operational strategies and plans to launch Robotaxi in seven additional cities in the first half of 2026. The company expects the transition from supervised to unsupervised operation in new cities to be shorter than the approximately six months experienced in Austin. Short-term fluctuations in NHTSA accident data are viewed as normal model stress-testing, with issues primarily concentrated on pick-up/drop-off processes—edge cases specific to ride-hailing that are less covered by Tesla's existing FSD mileage data.
On cost structure, Morgan Stanley believes Tesla holds a significant structural advantage. Using Model Y as a basis, Tesla's fully loaded cost is estimated at approximately $0.81 per mile, lower than Waymo's $1.43 and traditional ride-hailing's $1.71. As Cybercab production scales, Morgan Stanley projects costs could decrease further to $0.37 per mile by 2035, nearing management's long-term target of around $0.30 for the Cybercab.
The Cybercab's low-cost advantage is partly derived from its innovative manufacturing process. At the Austin Gigafactory, Tesla employs a modular "unboxed" architecture, replacing traditional body-on-frame, painting, and sequential assembly. The vehicle consists of five major sections—front module, central battery module, rear cargo module, and two side modules—produced in parallel and then merged. The exterior body panels are entirely plastic, manufactured via reaction injection molding with color integrated directly into the plastic. This process eliminates the need for a traditional paint shop, significantly reducing the factory's footprint. Morgan Stanley views the planned April 2026 start of Cybercab mass production as a critical milestone for validating these cost targets and directly impacting Robotaxi scaling.
Compared to the relatively clearer progress of Robotaxi, Optimus remains in earlier stages. Morgan Stanley expects the Optimus Gen 3 reveal may be delayed until the second quarter of 2026 but identifies the more crucial milestone as the start of production (SOP) in the second half of 2026. The humanoid robots rolling off the production line in 2026 are expected to have fairly limited functionality. Tesla has even suggested potentially establishing an "Optimus Academy" dedicated to data collection, model optimization, and robot training. Furthermore, a significant portion of the new computing power from the Cortex 2 supercomputing center will be allocated to Optimus training. Elon Musk disclosed on platform X that Tesla is developing "Digital Optimus"—a task orchestration tool for Optimus and even the Cybercab.
Within the five components of Morgan Stanley's $415 price target, Optimus (humanoid robots) contributes $60 per share, but this is already discounted by 50% probability, reflecting the market's pricing of high commercial uncertainty. In contrast, network services (including FSD subscriptions) contribute $145 per share, and Tesla Mobility contributes $125 per share, forming the two core supports of the target price.
Tesla's energy business remains an important growth driver, with strong demand on both the front-end grid-side and back-end customer-side. The company is adding 50 GWh of Megapack capacity in Houston while advancing a 7 GWh domestic LFP battery production line. However, Morgan Stanley highlights near-term margin pressure for the energy segment—intensifying price competition combined with the lagged impact of tariffs is expected to compress energy business gross margins to the mid-20% range this year. Regarding the core auto business, while Tesla has discontinued Model S/X production, it has not ruled out introducing new models, including derivatives based on the Cybertruck platform, launching Model YL in new regions, and the Roadster.
Morgan Stanley notes that as Tesla transitions towards physical AI and robotics, maintaining profitability in the core automotive (including FSD) and energy businesses is a fundamental prerequisite for supporting the current valuation, which implies approximately 40x 2030 EBITDA.
Morgan Stanley expects Tesla's capital expenditure, excluding the Terafab project, will exceed $20 billion in 2026, doubling year-over-year and creating an estimated free cash flow deficit of around $8 billion. Capital expenditure is projected to modestly decline to approximately $16 billion in 2027, with free cash flow expected to gradually approach breakeven as EV demand expectations recover and margins improve. Key variables influencing capital expenditure include the scale of internal Optimus robot purchases for training, the expansion pace of the Robotaxi fleet, incremental computing power investments required for FSD and Optimus training, and the scale of Tesla's in-house chip fabrication plant construction. Morgan Stanley estimates the total investment for the latter project could reach $35-$45 billion.
Tesla's cash reserves of approximately $44 billion provide near-term support for these substantial capital plans. However, Morgan Stanley explicitly states that if high capital expenditure persists and automotive business improvement lags expectations, the possibility of Tesla initiating opportunistic financing in 2027 cannot be ruled out.
