Palantir vs. RTX: Which Defense Stock Wins the Next Five Years?

The setup is simple: governments around the world are spending more on defense, and two very different stocks want your money for that trade.

One of them is Palantir (PLTR), the AI software company whose platforms help defense and intelligence agencies make sense of massive amounts of data. The other is RTX Corporation (RTX), the established defense giant — formerly Raytheon Technologies — that builds the actual physical stuff: missiles, radars, aircraft systems. In recent trading, PLTR ticked up about 1% while RTX gained over 3%, but the real comparison isn’t one day of green candles. It’s which business model you actually want to own through 2030.

Let’s break down why this is actually a hard question, not an obvious one. 👀

**Two completely different bets wearing the same theme**

Rising defense budgets is the headline. But Palantir and RTX are not the same bet on that headline — they’re exposed to it in totally different ways.

RTX is what people mean when they say “defense stock.” It has long-term contracts with governments, a massive backlog of orders, and revenue that comes from building and maintaining hardware. When defense spending rises, that money eventually flows into planes, weapons systems, and the maintenance contracts that keep them running. It’s slow, steady, industrial-scale money.

Palantir is a bet on a different layer of the same trend. Modern militaries generate enormous amounts of data — surveillance, logistics, intelligence — and Palantir’s software helps organizations actually use it. The company has expanded beyond government work into commercial AI platforms too, which is a big part of why it gets so much attention.

So the real question isn’t “which company is better.” It’s “what kind of investor are you trying to be here” — because the risk profiles are wildly different.

**The Palantir situation: great story, spicy price**

I want to be careful here, because Palantir is one of those stocks where the business and the stock price live in different zip codes.

The business has genuine strengths. Real government contracts, real commercial growth, and a product that sits at the intersection of two of the biggest spending trends of the decade: defense budgets and AI adoption. That’s not nothing. That’s a legitimate reason people are excited.

Here’s where the complicated part comes in: when a stock becomes this popular, a huge amount of the good news tends to already be baked into the price. “Priced in” just means investors have already paid up for expected future success. If a company needs to grow fast for years just to justify today’s price, the stock becomes expensive even if the company itself is doing well.

A useful way to think about valuation: it’s like paying luxury-brand prices for a hoodie. The hoodie might genuinely be great. But at some point, the price stops being about the hoodie and starts being about the hype around the hoodie.

Palantir’s valuation has historically been aggressive by almost any measure — and that’s fine to acknowledge while also admitting the business has performed. Both things can be true at once. A great company and an expensive stock are not mutually exclusive. The risk isn’t that Palantir fails. The risk is that Palantir succeeds and the stock still goes sideways for years because you overpaid for the success.

Also worth knowing: popular, momentum-heavy stocks tend to be volatile in both directions. Palantir can drop 30% on a quarter that’s merely “good but not spectacular” because expectations were sky-high. That’s not the company breaking — that’s the price catching up to reality.

**The RTX situation: boring on purpose**

RTX is the opposite temperament. Nobody’s making viral TikToks about missile defense systems. (Actually, someone probably is, but it’s not moving the stock.)

What you get with an established defense prime is scale, government relationships, and a contract backlog that gives visibility into future revenue. Defense spending is political, but it’s persistent — and RTX has been collecting on that persistence for decades. There are real risks here too: fixed-price contracts can go over budget, program delays happen, and large defense companies carry significant debt from mergers and acquisitions. RTX has had its share of technical and operational headaches in recent years. “Established” does not mean “risk-free.”

But the character of the investment is
