Archer Aviation vs. MP Materials: Which Stock Is a Better Buy in 2026?

The article compares two industrial growth stocks: Archer Aviation, which is developing electric air-taxi aircraft with FAA certification hurdles ahead, and MP Materials, the only fully integrated rare earth producer in the U.S. with government backing. While Archer shows promise in urban air mobility, it faces massive cash burn ($618M net loss in FY2025) with minimal revenue. MP Materials, despite also being unprofitable ($85.9M net loss), demonstrates stronger fundamentals with $275.5M in revenue (35% growth) and critical partnerships with GM, Apple, and the Pentagon. The author recommends MP Materials as the better 2026 investment due to its current market relevance and government support.
