The Trump administration’s new Project Vault plan to build a US$12 billion rare earths stockpile, alongside a reported 15% federal stake in MP Materials (MP), is pulling fresh attention to the stock.

That policy backdrop and the reported federal stake come after a mixed stretch for MP Materials’ share price, with a 7.53% year to date share price return alongside a very large 1 year total shareholder return of 165.90%. This suggests momentum has been rebuilding recently after some short term pullbacks.

With MP trading at US$59.11, some investors will point to the reported 33.8% gap to analyst targets and a very large 1 year return as signs of value, while others may see this as evidence that expectations are already rich. Is there still an opportunity here, or has the market already priced in future growth?

Most Popular Narrative: 16.2% Overvalued

Compared to MP Materials’ last close at $59.11, the most followed narrative pegs fair value at $50.85, suggesting the market is already paying a premium.

MP Materials represents the highest conviction idea in the sector for 2026. The market is currently pricing MP as a mining company, ignoring its imminent transformation into a high margin industrial manufacturer. The "10X Facility" partnership with the Department of Defense (DoD) 48 fundamentally de risks the downside while providing explosive upside.

Curious what kind of revenue mix and margin profile sit behind that price tag, and what sort of profit multiple this narrative leans on by 2030?

Result: Fair Value of $50.85 (OVERVALUED)

However, this story still hinges on MP scaling magnet production as planned and achieving higher margins, while any change in US government support could quickly challenge those assumptions.

Another Take: DCF Points the Other Way

While the user narrative lands on a fair value of $50.85 and calls MP Materials overvalued, our DCF model currently values the shares at $154.13, with the stock trading at $59.11. That is a wide gap in the opposite direction. Which story do you feel more comfortable with?
