Palantir (PLTR 1.32%) has been on a remarkable run since the artificial intelligence (AI) arms race began in 2023. Its stock is up over 2,700% since 2023, and has doubled in each year since then.
However, there is a bit of a problem with Palantir's stock. It has become drastically overvalued, and I think it could be ripe for a pullback in 2026, opening the door to other companies to surge past it.
Two AI companies that could be larger than Palantir by the end of 2026 are AMD (AMD 2.39%) and Salesforce (CRM 2.94%). Palantir currently sports a $435 billion market cap, while AMD and Salesforce are much smaller at $343 billion and $250 billion, respectively. Through a combination of these stocks rising and Palantir's falling, I think the order could be shaken up in 2026.

Why is Palantir overvalued?
As mentioned, Palantir's stock has risen by over 2,700% since 2023. However, its revenue is only up a mere 104%. That's because investors are willing to pay more for Palantir's stock now than they were three years ago. There is a limit to how much investors should be willing to pay, and Palantir is well beyond that threshold.

At 120 times sales and 254 times forward earnings, Palantir is among the most expensive stocks in the market. These levels also convey massive growth expectations that Palantir may not be able to live up to. As a result, I think a large pullback may be coming in 2026, as these levels are impossible to sustain unless Palantir's growth rate continues to accelerate.
I think Palantir's growth rate will moderate in 2026, which will send investors running. That opens the door for AMD and Salesforce, as each is slated to have a strong 2026 as well, but at a much more reasonable price tag.
The case for AMD
AMD has played second fiddle to Nvidia throughout the AI arms race. Its graphics processing units (GPUs) and the technology that supports them aren't nearly as advanced as Nvidia's, although that gap is starting to close. Management is bullish about its progress over the next few years and has released a bold projection for its business through 2030. They believe that their data center revenue growth rate will be around a 60% compounded annual growth rate (CAGR).
That's a huge step forward compared to Q3's 22% growth rate, and if AMD can deliver on these expectations, there's no doubt it will be a strong stock pick for 2026 and beyond. AMD isn't all data center computing, and its other two segments are expected to deliver a 10% CAGR. Overall, that will lead to a 35% CAGR through 2030, but that will be plenty to push AMD to become an excellent pick.
AMD's valuation isn't cheap at 11 times sales and 54 times forward earnings, but it's far more reasonable than Palantir's. If Palantir stumbles and AMD stays steady, AMD should be a larger company by the end of 2026.
The case for Salesforce
Salesforce has advertised its AI prowess, but has yet to see huge impacts in its financials. Salesforce is the industry leader in customer relationship management (CRM) software, and has saturated the market. It isn't easy to acquire new customers when you're only able to grow at the pace of the broader economy, so Salesforce has to create new products and upsell existing clients.

Although its revenue growth has struggled to cross the double-digit mark, its diluted earnings per share (EPS) have been phenomenal. This is a sign of a maturing business and has also brought Salesforce's valuation to a reasonable level. The stock trades for 22 times forward earnings, making it the cheapest stock on this list.
If Palantir stumbles due to high expectations and Salesforce continues chugging along with incremental growth, I wouldn't be surprised to see Salesforce at a higher market cap than Palantir by the end of 2026.
