MP Materials, which runs the only American rare earths mine, announced a new $500 million agreement with tech giant Apple on Tuesday to produce more of the powerful magnets used in iPhones as well as other high-tech products like electric vehicles.

Apple's $500 million investment in MP Materials is making headlines across the U.S. tech and defense sectors. In a bold move to boost American-made rare earth production, Apple is partnering with MP Materials—backed by a $400 million Pentagon deal—to reduce dependence on China.

US-based rare earth producer MP Materials has entered into a definitive, long-term agreement with tech giant Apple to supply US-manufactured, sustainable rare earth magnets. These magnets will be produced using 100% recycled materials in a significant step in both companies' commitment to sustainable and domestic supply chains.
