Public view, delayed 4h. Every headline, price and sentiment read below — and this write-up itself — reaches Pro subscribers live. Public readers see it once it clears the delay.

MP stock rose 5.77% to $56.88 in Friday’s session driven by renewed investor interest in rare earth materials and positive developments in U.S. supply chain policy. The stock opened with a 3.3% gap up and reached a session high of $58.52 before settling near $57.23. Recent reports suggest Chinese rare earth firms are pausing U.S. supply, reinforcing the strategic importance of U.S. producers like MP Materials.

What Happened

MP Materials shares surged in pre-market and early trading following a Reuters report indicating Chinese rare earth producers are halting U.S. exports. This development has boosted sentiment for U.S. rare earth firms, including MP Materials and USA Rare Earth. The company is also progressing on its long-term plans with support from the U.S. government, which has been a key factor in the stock’s recent momentum. The stock’s intraday performance reflected strong early demand, with volume reaching 1.7 million shares, 0.3 times the 3-month average.

What The Data Shows

The stock has gained 10.8% over the last eight sessions, moving from $53.93 to $59.78. MP Materials is currently unprofitable with an EPS of -0.34 over the trailing twelve months and a net margin of -14.6%. However, revenue has increased by 71.9% TTM. The stock opened with a significant gap up and reached a session high before consolidating. Recent insider activity includes a purchase by COO Michael Stuart Rosenthal on June 9, 2026, and a total of $543K in insider buys over the last 90 days with no sales reported.

What To Watch

MP Materials is not scheduled to report earnings in the near term. Investors should monitor the breadth of coverage and any new developments in U.S. rare earth policy that could further influence the stock’s trajectory.
