MP Materials Surges 6% as Traders Weigh Critical Minerals Growth Story; USA Rare Earth Rises 3%, Critical Metals Stays Flat

MP Materials (NYSE:MP) stock surged 6% to $48.29 on Wednesday as traders weighed the company’s critical minerals growth story. USA Rare Earth (NASDAQ:USAR) shares rose 3% to $14.44, while Critical Metals (NASDAQ:CRML) stock stayed essentially flat, up 0.1% to $7.39. Rare-earth names showed selective strength after a recent sector pullback.

The VanEck Rare Earth and Strategic Metals ETF (NYSE ARCA:REMX) slipped 0.57% to $64.42. Broader markets advanced, with the SPDR S&P 500 ETF Trust (NYSE ARCA:SPY) up 0.47% to $767.80. MP Materials has drawn attention this week as second-quarter operating progress and near-term magnet shipments to General Motors kept the growth narrative intact. Outside commentary continues to question whether the stock’s valuation depends heavily on government support, while investors watch fourth-quarter commercial magnet deliveries as the next major proof point.

MP Materials Rebounds on Magnet Progress

MP Materials shares recovered ground after a sharper decline over the prior month that left the stock down roughly 21%. The company has advanced its downstream magnetics strategy, with magnets already delivered to General Motors for in-vehicle qualification and regulatory testing. Commercial shipments are expected to begin in the fourth quarter of 2026 from the Independence Facility in Fort Worth, Texas.

Second-quarter results showed revenue rising 89% year over year, NdPr production up 41%, and adjusted EBITDA turning positive. The Magnetics segment continues to scale as MP Materials shifts from magnetic precursor products toward finished neodymium-iron-boron magnets under its long-term supply agreement with General Motors.

USA Rare Earth Advances, Critical Metals Holds Steady

USA Rare Earth stock posted a solid gain. The company is developing a domestic rare-earth supply chain focused on mining and magnet production outside China. USA Rare Earth shares have moved with broader interest in U.S.-based critical minerals projects even as individual catalysts differ across the group.

Critical Metals stock remained nearly unchanged. Critical Metals holds an early-stage rare-earth project in Greenland that has attracted attention amid recent geopolitical developments, though the company remains at a different stage of development than more advanced producers. Both USA Rare Earth and Critical Metals operate within the same strategic metals theme but lack MP Materials’ established mining and near-term commercial magnet production.

Rare Earth Group Reflects Selective Interest

The VanEck Rare Earth and Strategic Metals ETF’s modest decline indicated limited broad participation beyond the leading names. Texas has emerged as a growing hub for America’s rare-earth supply chain, with MP Materials’ Fort Worth magnet facility representing a visible piece of the domestic buildout. Demand drivers include electric vehicles, defense applications, and electronics, yet the sector remains sensitive to policy shifts and commodity pricing.

Similarities among MP Materials, USA Rare Earth, and Critical Metals include exposure to efforts to reduce reliance on Chinese rare-earth processing and magnet production. Differences center on operational maturity, with MP Materials already producing oxides at Mountain Pass and preparing commercial magnet shipments, while the peers remain earlier in their development timelines. Valuation debates continue to focus on the role of government financing and offtake support.

MP Stock: What to Look For Now

MP Materials’ rebound highlights ongoing interest in its path from mining and processing into higher-value magnet manufacturing. Fourth-quarter commercial deliveries to General Motors represent a key milestone that could help validate the downstream strategy. At the same time, the stock’s sensitivity to sector sentiment and questions around long-term profitability without policy support remain points of caution.

Investors in MP Materials stock should consider keeping position sizes modest given the volatility typical of critical minerals equities. Successful ramp of magnet production, sustained offtake agreements, and further operating improvements could support MP Materials shares, while delays in commercial shipments or weaker rare-earth pricing may renew pressure across the group.
