Let's start with price to earnings growth. Decades ago, Peter Lynch claimed that a PEG of 1 was a fair price. Partly because interest rates are now lower and partly because there is even more demand for stocks than in Lynch's time, the typical PEG is now about 1.3 instead of 1. The PEG Ratio divides the forward P/E by its projected growth rate.
Nvidia's projected rate of growth is about 50% annually and its current forward P/E is about 25 ... so, 25/50 =0.5. (The 0.6 in the table above uses more precise, and slightly different numbers to arrive at 0.6 instead of 0.5. Any given day you could plug in new numbers and end up with a slightly different value. The stock market is hardly precise in its valuations that literally change minute to minute but for our purposes, 0.5 or 0.6 are essentially the same.) Price to earnings growth for Nvidia suggests that you're paying a low price for future earnings.
To buy Tesla, by contrast, means paying a really high price for future earnings. Analysts are projecting fairly healthy growth rates for Tesla. Annual earnings growth of about 30 to 35% - if realized - is really impressive. But investors have driven up the price of Tesla to the point that they are paying about $180 for every dollar of future earnings, so the current P/E is about 180. 180 divided by 35 (projected earnings growth rate) and you get a PEG of about 5. This suggests that you're paying a remarkably high price for future earnings.
So now let's look at the businesses.
Put aside the servers for a moment and focus instead just on Nvidia's plans for cars. Nvidia is equipping companies like Toyota & Lexus, Jaguar Land Rover, General Motors, Hyundai Motor Group, Geely, Nissan, Mercedes-Benz, Volvo Cars, Li Auto, Lucid Motors, Xiaomi EV, JLR, and Isuzu with their Orin processor and more advanced Thor chip and self-driving system. Nvidia's Drive Thor platform is a centralized car computer that integrates autonomous driving, AI cockpit features, passenger entertainment, and safety systems into a single architecture. Additionally, Nvidia is working with a variety of autonomous trucking and robotaxis manufacturers.
Nvidia will handle the training of this self-driving capability and provide the integrated chip and self-driving system for these (and likely many other) car companies. Any one of these companies might fade into bankruptcy or become the newly dominant car company. Nvidia will have a diversified investment in these companies. Some will sell far more cars in this new world of self-driving cars. Some will sell fewer. Nvidia will sell to them all and because of this is almost certain to do well even as individual companies find their own fortunes rise and fall.
And the business model has enormous potential. Nvidia's data centers will be processing data from all of these cars, regularly getting smarter as it is trained on all this real world data flowing in from a growing fleet of varied cars. Every car that uses this system will make Nvidia's self-driving technology smarter, adding more experience. And Nvidia will make money on a subscription model that will drive this. That is, car companies will charge a monthly fee for this continuously evolving intelligent driving system. And drivers will find this a bargain. Why? They will no longer need collision insurance because cars are driving, not the driver. The car will assume liability for the driving and - even bigger bonus - will dramatically lower the odds of an accident. And every single car whose experience feeds into Nvidia's system will make this system smarter and thus more valuable. Nvidia won't just be selling Thor (or next generation) chips to auto makers to use in each car; they will be selling the artificial intelligence that guides these cars. Software as subscription will come to cars and Nvidia will be the big beneficiary. (This is somewhat akin to what Microsoft did with the explosion of laptops and desktop computers made by dozens of computer manufacturers. Windows - and then Word, and Excel, etc. - ran on all of these systems and Microsoft thrived regardless of who was making the Windows PC.)
The reason that Tesla sells at a PEG of about 5 is because people see the possibility of Tesla doing this with its one brand of car. Nvidia plans to do this with nearly every other brand of car. If you had a chance to invest in just one brand or dozens, which "package" of brands do you think is more likely to contain the really successful brands, or most popular cars? In the early days of personal computers, Microsoft emerged as hugely profitable company not because they made those personal computers but because they offered the operating system and then popular apps that ran on all of the different brands. Nvidia is doing something similar with self-driving cars, which will probably be the only kind of car sold within a decade.
Here is another twist. The data centers that Tesla will use to train its own self-driving models? Those are Nvidia's. Even as Tesla has success - and they likely will have success - it will feed into Nvidia's success.
And of course Nvidia is not just selling its Thor chip and self-driving capability. That is an adjacent to its bigger business model right now of creating increasingly sophisticated AI that is going to transform businesses across the globe. Right now, these data centers dwarf the self-driving car market. They will likely continue to do so.
So there is a future in which two things are true. One, Nvidia's profits from self-driving cars and technology are greater than Tesla's profits from the same. And two, Nvidia's profits from other dimensions of the AI economy could dwarf their own profits from self-driving cars. (This is a dimension of their business that is - quite reasonably - the focus of most analysis.)
So, consider this possibility. Tesla has its one car using its self-driving technology and intelligence and Nvidia has dozens of automakers using its self-driving technology and intelligence. Tesla will try to expand from the cars into things like robots and AI; Nvidia already is dominant in the realm of AI and is very well positioned to dominate in robotics and related fields that will emerge as AI evolves.
What does this mean to me? I'd be dubious if Nvidia currently had a PEG of 5 (like Tesla now does) but get why people are so excited about its prospects. I don't get why Tesla has a PEG of 5 but could understand why people might price it so that its PEG was 0.6 (like Nvidia). That is, if the PEG for these two stocks were reversed, I might gently suggest that investors reconsider and perhaps shift some of their Nvidia equity into Tesla. Given the current extremes of these two, though, I can't see making any suggestion other than sell your Tesla stock and buy Nvidia.
As the first wave of Drive Thor vehicles and Project GR00T warehouse robots officially deploy over the next 12 to 24 months, we will see if Wall Street is forced to adjust its models and finally price in the recurring software monetization that makes the current valuation of Nvidia look like a bargain.
For the record, as of 9:30 AM Pacific time, 1 September 2026 as I write this, the stock prices were:
Nvidia $219.21, a P/E of 27.7
Tesla $356.74, a P/E of 331.4
If I'm right about any of the above, Nvidia's stock price should be higher than Tesla's within 6 months. Probably sooner. And for the record, this is an exceptional post for me. I don't intend to turn this into a stock analysis blog but this particularly egregious pairing of mis-priced stocks has simply annoyed me to the point that ... well, you get this post.
