The Real Engine That Could Power Tesla Stock Higher

Forget the humanoid robots for a minute; the most potent catalyst for the stock may already be hitting the streets, and it’s growing exponentially.

After a rough few months that have seen the stock slide 18.1%, it’s easy to get lost in the noise around Tesla (TSLA). There’s talk of new factories, humanoid robots, and electric semi-trucks. But if you’re looking for the single, evidence-backed driver that could materially re-rate this stock, you might want to look past the hardware and focus on the software that’s already quietly scaling at a rapid pace.

The Foundation Is Firmer Than You Think

The core business of selling cars is showing surprising strength. The company just posted record Q2 deliveries, and management noted on its latest call that it ended the second quarter with its largest order backlog since 2023. That’s a solid base. The more compelling story, however, lies in why people are buying the cars. And increasingly, the answer is software.

Is This a Car Company Anymore?

Management is seeing a fundamental shift in customer behavior. In North America, about 55% of deliveries in the second quarter had a full self-driving, or FSD, subscription enabled at delivery. The CEO put it bluntly: “they’re actually buying Tesla full self-driving with a car attached as opposed to a car with FSD.” This amounts to far more than another feature; it’s a high-margin, recurring revenue stream that hints at a future where Tesla is valued less like a carmaker and more like a software-as-a-service powerhouse. While the stock’s performance often reflects broader market trends, as we explored in a recent analysis, this internal shift could be a unique driver.

“Literally Exponential” Growth Is Already Underway

This is where the thesis leaves the station. The Robotaxi program, built on that same FSD software, is no longer a distant dream. It’s live in cities across Florida and Texas, and its growth is significant. Management described the ramp in unsupervised miles as “literally exponential,” compounding at a rate of “more than 10% a week.” That’s a remarkable trajectory. While the current fleet is small, the goal is to prove the technology is generalizable, that it can work anywhere without bespoke engineering for each new city. If you’d rather own the broader consumer sector than a single name, a consumer discretionary ETF like XLY holds Tesla among its largest positions.

The entire bet hinges on scaling this network safely. Management is acutely aware that a single major incident could bring regulators down hard. But if Tesla can maintain its safety record while sustaining that exponential growth, it unlocks a business model that could dwarf the act of selling cars. It’s the difference between selling a product once and selling a high-margin service, mile after mile, for years to come. A shift of this magnitude has the potential to transform a stock, going well beyond simple support.

Where Does An Opportunity Like This Show Up First?

An opportunity like this only counts once it starts showing up in the numbers, and the first hard place it surfaces is management’s guidance. The moment a company can actually see the new revenue coming, it raises its forecast, and a raised forecast that the market is already rewarding is about the cleanest proof a story like this is turning real. Viatris (VTRS), Westinghouse Air Brake Technologies (WAB), and West Pharmaceutical Services (WST) are flashing exactly that signal right now. Our Guidance Momentum screen tracks every S&P 500 name where a rising forecast is already meeting real price momentum, so you can hunt for the next opportunity like this one while it is still early.
