Palantir's Five-Year Stellantis Partnership Extension Fails to Lift Stock Amid Valuation Concerns

Palantir renewed and expanded its partnership with Stellantis for five additional years on March 30, 2026, focusing on AI-powered industrial transformation through increased use of Foundry platform and deployment of AIP. Despite the partnership announcement, PLTR shares dropped 4% that day and are down 17-22% year-to-date, with the 220x P/E ratio and insider selling weighing on investor sentiment even as analysts like Jim Cramer maintain bullish long-term views citing strong commercial growth fundamentals.
