By Lyle Daly – Apr 2, 2026 at 10:00AM ESTKey PointsPalantir Technologies is known for trading at a sky-high valuation.Its PEG ratio is less than 1, which can be a sign of an undervalued stock.Palantir Technologies (PLTR +0.42%) is a polarizing company, but one area of consensus is the valuation. It's seen as extremely expensive, and most metrics support that notion. Case in point, Palantir currently trades at a whopping 226 times trailing earnings. However, there's one important metric that tells a different story about this artificial intelligence (AI) stock: price/earnings-to-growth (PEG) ratio. Image source: Getty Images. PEG ratio takes a stock's price-to-earnings (P/E) ratio and divides it by the expected earnings growth rate. A PEG ratio of 1 generally indicates that a stock is fairly valued, and anything under 1 indicates an undervalued stock. Palantir's PEG ratio is 0.964 at the time of this writing, which barely puts it in the undervalued range, but it's still a stark difference from other metrics. While P/E ratio only looks at Palantir's earnings and share price, PEG ratio also accounts for the fact that Palantir's earnings per share grew 232% year over year in 2025. It's worth noting that no metric, or combination of metrics, tells you everything. Also, Palantir's earnings growth is partly due to improved profit margins, which reached a new high of 43% in Q4 2025, up from 10% in Q4 2024. That kind of jump can only happen once. Palantir may continue to improve margins, but it can't quadruple them again.

I think the growth rate justifies a premium, but how much of a premium it's worth depends on the investor and their risk tolerance.Read NextApr 2, 2026 •By Keithen DruryIs Palantir the Ultimate Hypergrowth Stock?Apr 1, 2026 •By Daniel SparksPalantir Stock Soared Last Year.
