Just caught something interesting about Palantir that's worth paying attention to. You know how CEO Alex Karp has been pretty vocal about calling out short-sellers? Well, turns out he's been quietly dumping his own stock. We're talking $2.2 billion in sales over the last three years. That's the kind of signal that usually means something.

Now, to be fair, Palantir has been crushing it. The company's basically the leader in AI-powered data analytics right now. Their Gotham and Foundry platforms help organizations make sense of massive datasets using machine learning models that get smarter as they capture more information. Forrester ranked them as a top player in AI decisioning platforms, and Morgan Stanley analysts are saying they're becoming the enterprise AI standard. The financial results back it up too - 70% revenue growth in 2025, 34% increase in customer count, and they're guiding for 60% growth in 2026. That's the kind of execution that justifies real attention.

But here's where it gets tricky. Palantir stock is trading at 74 times sales. Let that sink in. The entire S&P 500, and Palantir is the most expensive stock several times over. Even after dropping 37% from its peak, it would need to lose more than half its value just to stop being the most expensive name in the index. AppLovin is second at 30x sales. There's a massive valuation gap here.

Michael Burry, the investor known for his contrarian bets and significant net worth, disclosed a short position against the company in Q3 2025, and Karp immediately claimed it was market manipulation. But Karp himself? He still owns about $832 million worth of stock after selling $2.2 billion. That's not nothing, but his actions are speaking louder than his words about short-sellers.

The thing is, you can have great fundamentals and still have a risky risk-reward setup. Palantir's doing everything right operationally, but the valuation is pricing in a lot of perfection. The AI hype has been real, but sometimes that's exactly when you need to be most careful. If you've got a solid position in Palantir, might be worth thinking about taking some profits here. The stock can be both a strong company and an expensive stock at the same time.
