MP Materials Corp. is an American rare-earth materials company headquartered in Las Vegas, Nevada. MP Materials owns and operates the Mountain Pass mine, the only operating rare earth mine and processing facility in the United States. MP Materials focuses its production on Neodymium-Praseodymium (NdPr), a rare earth material used in high-strength permanent magnets that power the traction motors found in , robotics, , drones and other advanced motion technologies. MP Materials is listed on the New York Stock Exchange under the ticker symbol "MP". As of December 2021, JHL Capital Group, QVT Financial and CEO James Litinsky were the company's three largest shareholders, with about 7.7% of the company owned by Shenghe Resources, a Chinese company partly owned by the country's Ministry of Natural Resources. In July 2025, the United States Department of Defense announced a deal that would make it the largest shareholder of MP Materials.
Following the asset acquisitions and formation of the entities that became MP Materials, the company restarted operations at Mountain Pass. On July 15, 2020, the company announced a reverse takeover whereby MPMO and SNR would be merged with Fortress Value Acquisition Corporation to become a public company under the name MP Materials Corp. The transaction, which closed on November 17, 2020, raised $545 million. On November 18, 2020, MP Materials began trading on the New York Stock Exchange under the symbol "MP".
In December 2021, MP Materials signed a long-term agreement with General Motors to provide Neodymium magnet for use in GM's electric vehicle motors. As part of the contract, MP Materials also agreed to provide alloy and finished magnets to GM for its electric vehicles and to open a new factory located in Fort Worth, Texas to produce the magnets.
As of December 2021, JHL Capital Group, QVT Financial, and CEO James Litinsky were the company's three largest shareholders, and about 7.7% of the company was owned by Shenghe Resources. Apart from institutions, other investors own 18%.

In January 2025, MP Materials announced that their Independence facility in Fort Worth, Texas has commenced neodymium and praseodymium (NdPr) metal production. According to the company, Neodymium magnet will be the first rare earth products to be refined in the United States which has long depended on foreign sources, particularly China.
In April 2025, Shenghe Resources stated that its U.S. affiliate, MP Materials, had stopped shipping minerals for processing due to the tariffs in the second Trump administration.
In May 2025, the Saudi Arabian Mining Company (Ma’aden) and MP Materials entered into an agreement to establish a rare earth supply chain within Saudi Arabia. The development took place during President Trump’s visit to the Middle East.
On July 15, 2025, Apple announced a $500 million investment in MP Materials, following the Trump administration's efforts to reduce U.S. reliance on China for rare earth elements. The announcement came a few days after the U.S. Department of Defense agreed to a multibillion-dollar investment to build a new rare earth magnet facility called the "10X Facility."
MP Materials produced 28,000 tonnes of rare-earth oxide equivalent from Mountain Pass in 2019, and 38,500 tonnes in 2020, or more than 15% of global production. As of late 2020, Shenghe Resources was the sole purchaser of MP Material's rare earth concentrate.
As of 2023, MP Materials had a three-stage plan for scaling its operations:
As of 2023, stages II and III were underway and the company had begun production of refined rare earths. MP Materials signed a supply chain agreement with Japanese trading house Sumitomo Corporation in 2023.
On September 30, 2020, Donald Trump issued an executive order targeting China's dominance of rare earth materials. In the executive order, he expressed concern for the heavy reliance of the US on China for 80 percent of rare earth materials. He reiterated the importance of producing and refining rare earth in the US and discussed various tariffs and government grants to rare earth material companies such as MP Materials.
In 2021, MP Materials received $3 million in funding from the United States Department of Energy to design and study the feasibility of a system to produce rare earth oxides and metals from coal by-products in collaboration with the University of Kentucky.
In February 2022, U.S. President Joe Biden announced at a press conference that the United States Department of Defense was investing $35 million into MP Materials as part of an effort to spur domestic rare earth production in the United States. Biden said that this move was designed to reduce America's reliance on rare earth minerals imported from other countries. The Biden administration said the federal funding is earmarked to assist the company to develop a new commercial facility for “heavy” rare earth mineral processing.
On May 24, 2024, the Biden Administration announced a 25 percent tariff on rare earth magnets from China, set to take effect in 2026. This marks the first time that critical minerals, including rare earth magnets, have been specifically included in the tariffs. Following the tariffs MP Materials put out a statement listing the tariffs. After the announcement, CEO James Litinsky attended an event with Biden at the White House.
On July 10, 2025, MP Materials announced that the United States Department of Defense will become its largest shareholder. The announcement came after the Pentagon agreed to buy $400 million of preferred stocks in the company. As part of this multibillion-dollar deal, MP Materials will construct a new rare earth magnet facility called the "10X Facility." The initiative comes as the US looks to reduce reliance on foreign countries, particularly China, which currently supplies approximately 80% of the rare earth elements used in the US.
