Down 0.5% in 2026, Is Palantir Stock a Buy?

Palantir Technologies has underperformed the market in 2026 despite accelerating AI-driven revenue growth of 93% year-over-year and strong commercial momentum. The company's security-focused approach and high profit margins (55% net margin) are attracting enterprise and government clients, but the stock's valuation of 50x 2026 revenue and 108x forward earnings presents significant risk if growth slows.
