Wall Street has been eyeing up rare earth stocks due to the government taking large stakes in many of them. One stock in particular has vaulted into the market's spotlight, as it is arguably the most major rare earth company in the U.S. and received the first government rare earth investment.
The company in question is MP Materials (MP), and it operates the Mountain Pass mine in California, near Nevada's border. It received a $9.6 million tech investment in November 2020, followed by a jumbo $400 million equity stake in July 2025 to build magnet manufacturing facilities. Soon after, it signed a $500 million deal with Apple (AAPL).
