Palantir Just Had Its Best Quarter Ever. The Stock Crashed Anyway. Here's Why.Revenue grew 85%. Earnings per share beat estimates by 18%. Palantir raised guidance for the full year to $7.65 billion. By almost any measure, Palantir Technologies' (PLTR) Q1 2026 report was flawless. The stock fell 7% the next morning. That reaction isn't random noise. It's telling you something important about where this company stands right now, and what you need to understand before touching the stock. ## The Quarter Wall Street Can't Dismiss The numbers from Q1 2026 are genuinely remarkable. Total revenue hit $1.63 billion, up 84.7% from a year ago. U.S. revenue grew 104% year-over-year. U.S. commercial revenue, the newer and faster-growing segment, surged 133%. EPS came in at $0.33, beating analyst estimates of $0.28 by 18%. Adjusted operating margin was 60%, with gross margin at 88%. These are software-company-on-steroids numbers. Full-year guidance implies 71% growth for 2026. The company's Maven AI system is expected to become an official Pentagon program of record, with a potential $10 billion in software purchases available over a decade. Hold on. Let me stop here. A company growing revenue 85%, raising guidance, printing 60% operating margins, and it's down 7%. That only happens one way: when the price already had all of that baked in, and then some. ## The Valuation Problem Michael Burry Won't Let Go Palantir trades at roughly 215 times trailing earnings. Forward P/E is around 110x. Price-to-sales is 78x. Even with that 85% revenue growth, you're paying a steep price for every dollar of earnings. Michael Burry, the investor who called the 2008 housing collapse, has been openly bearish on PLTR for months. His point: Palantir's market cap puts it in the same weight class as Lockheed Martin and Raytheon combined, defense contractors with decades of proven cash flows. You don't have to trust Burry. Trust the math. At 78x sales, Palantir needs to sustain revenue growth at 60% or better for years just to justify its current price at a more reasonable 20x sales multiple. That's a high hurdle. Possible. Not guaranteed. ## The Karp Controversy Then there's the manifesto. In April 2026, a 22-point document attributed to CEO Alex Karp started circulating on X. It advocated for American dominance and contained statements that critics found inflammatory, including a line suggesting that "Some cultures have produced vital advances; others remain dysfunctional and regressive." UK Members of Parliament called it "the ramblings of a supervillain." Amnesty International escalated its criticism of Palantir's work with ICE, the Israeli military, and government surveillance programs. Australian lawmakers questioned whether Palantir should hold government contracts at all. None of this is new criticism. But the manifesto gave it fresh oxygen at the worst possible time, just as Palantir is pushing to sell its AI platform to foreign governments. That reputational overhang is real. It won't kill the company. But it's a friction point that doesn't exist for most of Palantir's peers. ## Bottom Line Palantir (PLTR) is a genuinely exceptional business growing at a genuinely exceptional rate. Revenue up 85%, operating margins at 60%, guidance raised, and sole-source positioning in the U.S. government AI buildout. The problem isn't the business. It's the price. At roughly $80 per share, with analyst fair value estimates around $153 on average, the stock is pricing in a lot of future success with no margin for error. Any slowdown in commercial growth, any lost contract, or any escalating controversy from the Karp manifesto could compress that premium fast. For high-conviction growth investors willing to pay up, PLTR remains a legitimate long. For anyone who needs a margin of safety, this entry point hasn't appeared yet.
