Palantir shares rise 5% premarket as AI-fueled demand powers annual guidance raise
Investing.com -- MP Materials Corp (NYSE:MP) shares fell 5.1% as the market responded to the company’s announcement on April 17, 2025, of ceasing rare earth concentrate shipments to China due to increased tariffs and export controls. The decision comes as a direct challenge to China’s retaliatory tariffs and a move to align with American national interests.
The company’s bold strategy to stop selling its critical materials under a hefty 125% tariff has led to an immediate stockpile of concentrate while they accelerate their downstream operations. This includes ramping up oxide production, fast-tracking heavy rare earth separation, and initiating magnet production in Texas. Despite these efforts, investors seem wary of the short-term dislocation that could arise from this significant shift in operations.
MP Materials has invested nearly $1 billion to restore the full rare earth supply chain within the United States, a move that reflects a long-term vision to withstand short-term market volatility. The company’s California refinery is currently processing nearly half of its production, with the majority of this material being sold in markets outside China, including Japan, South Korea, and the United States.
The company has noted an influx of inquiries from manufacturers in critical industries seeking a secure and resilient source of materials and magnets in the wake of their strategic shift. MP Materials believes it is uniquely positioned to meet these demands and is in active discussions with federal leaders to garner support for American industry.
Despite the proactive measures taken by MP Materials to mitigate the impact of the trade tensions and to reindustrialize the rare earth supply chain on American soil, investor sentiment has taken a hit in the short term, as reflected in the stock’s decline. The company remains focused on its mission and is working closely with customers and U.S. government partners to accelerate its strategy and lead the effort in securing a domestic supply chain for the future.
