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

A Morgan Stanley analyst, Andrew Percoco, recently raised his bull-case target price for Tesla (TSLA -0.67%) from $820 to $840 while maintaining an equal-weight rating and a $400 price target in his base-case scenario. (The shares now trade for about $357.) Wall Street analysts often provide a range of price targets reflecting various outcomes, and investors shouldn’t get too excited by one that nudges the target higher by 2.4% in the best-case scenario. Nevertheless, one reason for the update highlights the long-term potential of a part of Tesla that doesn’t get enough attention.

The investment case for Tesla stock

Although the company is best known for its hardware products, including electric vehicles (EVs) and energy storage, its future lies in higher-margin recurring revenue from its physical solutions, namely robotaxis (including its dedicated robotaxi, Cybercab) and Optimus robots. To be clear, if you don’t believe in these businesses, then you have no other reason to hold a stock trading at 200 times its estimated 2026 earnings.

However, Tesla’s investment case is exciting and, on the transportation-as-a-service side, rests on the potential for recurring fare revenue from its own Cybercabs, its share of fare revenue from third-party operators, and full self-driving (FSD) software. Optimus will likely operate under a robot-as-a-service model, generating long-term recurring software revenue.

Yet, Tesla has another exciting business with significant revenue-growth potential: the Tesla Semi truck.

What Wall Street expects from the Tesla Semi

Tesla plans to make money from its Semi truck through a combination of hardware sales, charging services, and software subscription revenue. While the latter may be seen as akin to FSD revenue from passenger cars, it has much higher revenue per vehicle because trucks are driven many more miles. In fact, the key cost advantage of EVs really shines when you maximize the per-mile advantage by driving more.

That’s why the Morgan Stanley update discusses the possibility of more than 80,000 autonomous Semi trucks on the road by 2040, each generating as much as $18,000 a month in FSD revenue. . It’s a scenario that could lead to more than $17 billion in high-margin FSD revenue by 2040.

Although 80,000 trucks and 2040 are a long way off, the Wall Street outlook, according to Visible Alpha, calls for Semi units to rise from 4,000 in 2027 to 12,000 in 2028 as production ramps up. That growth will likely be driven by the Semis’ lower cost per mile than that of a typical diesel truck (a point noted by the Morgan Stanley analyst), as demonstrated by a highly successful pilot with PepsiCo.

Where next for Tesla’s Semi

Tesla Chief Executive Officer Elon Musk said on the last earnings call that “the total number of units of the Tesla Semi is still low and will continue to be a very small percentage,” and that’s why Tesla is focusing on developing v15 FSD for its Model 3, Model Y, and Cybercab/robotaxi fleet first. Musk said developing FSD for the Semi is “taking a bit of a backseat for the next six months.” However, he also noted that “it will definitely be working next year and in time for the scale-up to high production of the Tesla Semi.”

To be clear, all of this assumes Tesla will overcome regulatory hurdles for passenger-car FSD, let alone Semi trucks, and that adoption rates for the Semi will grow. In addition, there’s no guarantee Tesla Semi trucks will be driven as expected, and Morgan Stanley still has an equal-weight rating on the stock.

All told, investors should not view Semi in isolation when considering the benefits of developing FSD for the Cybercab/robotaxi fleet. Not least because it will strengthen investor confidence in the development of an autonomous Semi, which could become another significant source of recurring income. It’s not a near-term earnings driver, but it is one to pencil in for long-term growth, provided Tesla’s FSD ambitions progress as planned.
