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

October 27, 2026 · by alexmoreno

Two stocks, one theme, and a genuinely interesting question: if global defense spending is climbing, do you ride it with Palantir (PLTR) — the AI software company that governments actually buy from — or RTX Corporation (RTX), the old-school defense giant behind missiles, engines, and jet systems?

It’s basically the “app vs. hardware” debate, but with fighter jets involved. Let’s break it down, because the answer isn’t as obvious as the hype on your feed makes it look. 👀

## Why defense spending is the theme right now

Countries around the world are increasing military budgets. Geopolitical tension, rebuilding stockpiles, modernization programs — the money is flowing. That’s the part of the story everyone agrees on.

The interesting part is *how* differently Palantir and RTX capture that money.

**Palantir** sells software. Its platforms help defense and intelligence agencies make sense of massive amounts of data — think of it as the decision-making layer on top of all the sensors, satellites, and records a military generates. It’s AI-heavy, software-margins-heavy, and it’s the kind of story that gets retail investors genuinely excited, because “AI for the Pentagon” sounds exactly like the future.

**RTX** makes physical stuff. Formed from the merger of Raytheon and United Technologies, it builds missiles, air defense systems, aircraft engines, and aerospace components. It’s slower, heavier, more industrial — and it benefits from defense budgets in a more traditional way: contracts, backlogs, and long production cycles.

Same tailwind. Completely different business models. That distinction matters more than the ticker symbols.

## The Palantir situation: great story, priced like a fairytale

Here’s the thing about Palantir that I want you to really sit with: **the company and the stock are not the same thing.**

The company? Legitimately impressive. Real government contracts, real products, real growth. This isn’t a vaporware story. Palantir’s software is genuinely deployed by defense and intelligence customers, and it’s been expanding into commercial markets too.

The stock, though, has historically traded at valuations that assume a *lot* of continued perfection. When you hear people talk about Palantir being “expensive,” they’re usually talking about valuation multiples — ratios like the P/E ratio (price-to-earnings), which tells you how many dollars investors are paying for each dollar of the company’s profit. A high P/E isn’t automatically bad. It means investors expect rapid growth. But it means the price leaves very little room for an okay quarter.

Think of it like paying luxury-brand prices for a hoodie. Maybe the hoodie is genuinely great. But you’re not paying for the hoodie — you’re paying for the *story* of the hoodie. If the story hits even a small speed bump, luxury-brand prices have a long way to fall.

This is why Palantir is one of the most polarizing stocks on the internet. People who own it feel like geniuses on green days. People who missed the rally feel FOMO and chase. Neither emotion is a research process. 📱

## The RTX situation: boring on the outside, complicated on the inside

RTX doesn’t trend on your feed, which is precisely why some investors overlook it. Defense giants work differently: they win multi-year contracts, build enormous backlogs (orders booked but not yet delivered — basically guaranteed future revenue), and grow steadily rather than explosively.

You’re not buying a moonshot. You’re buying a slow snowball — large, established, harder to disrupt, and connected to the same rising defense-spending tide Palantir is riding.

That said, “established” doesn’t mean “simple.” RTX carries real scale challenges: massive manufacturing operations, program execution risk (big defense programs run late and over budget more often than anyone tweets about), and exposure to the commercial aerospace cycle through its engine and systems businesses. It’s not a pure defense play, and that cuts both ways depending on the year.

The stock moving up sharply on a given day — like the +3.39% in the comparison we’re looking at — usually reflects the market re-pricing the defense theme itself, not some sudden change in RTX’s actual business. One green day is sentiment. Backlogs
