In May 2026, the US Department of Energy selected USA Rare Earth for a $50.5 million proposed separation in Oklahoma. This move alone is modest, but its importance lies in how it fits into a broader pattern of U.S. support for the rare earths industry. The United States is trying to build a system that can make non-Chinese suppliers commercially viable. This shift is necessary, but it also raises an important question for U.S. rare earths strategy: Can Washington maintain lasting support for the industry?
China’s dominance in the rare earth supply chain makes its export controls particularly powerful. In 2024China accounted for 60 percent of global magnetic rare earth mining production, 91 percent of refined production, and 94 percent of permanent magnet production. Under these conditions, China export licensing system does not need to become a total embargo to create pressure. This can keep trade officially open while making access conditional, slower, and subject to stricter end-use review when tensions rise. For U.S. manufacturers, key inputs may remain available in principle but become unreliable in practice.
This problem is not new. After the rare earth clash between China and Japan in 2010, Washington and private investors had already strong incentives to balance an alternative offer. But rare earth projects require strong commitment across political cycles, and this sustainability (or lack thereof) is the problem the United States has not been able to solve.
The renaissance and later collapse of Molycorp is a direct example: during a crisis, alternative suppliers can mobilize government and private sector attention, but these companies tend to collapse once prices weaken and buyers return to cheaper sources. Rare earth resilience cannot survive on strategic urgency alone.
This explains why the new American approach can be seen as a way of shaping the market. Washington is trying to change market conditions that have undermined previous alternatives: volatile prices, uncertain buyers, weak private financing and limited processing capacity. The clearest example is the Pentagon’s partnership with MP Materials since July 2025. By combining equity investment, price floors and long-term purchase commitments, the government acts more like an investor, insurer and lead buyer than a financier. The goal is to make U.S. base production bankable and more resilient before the next shock arrives.
What makes this approach special is also what makes it risky. Previous American efforts recognized the problem of dependencybut treated it primarily as a capacity problem: encourage alternative projects and supply would eventually adjust. The new approach treats it as a credibility problem. The problem is that companies, investors and buyers may not engage on a large scale if they do not believe that non-Chinese supply will remain commercially viable once the immediate shock has passed. This requires Washington to ensure that support does not disappear when prices fall, political attention shifts, or China changes tactics.
When private investment depends on public credibility, policy itself becomes part of the market. This is where the durability test begins.
Credibility is first tested politically. Business-specific financing is different from general tax incentives because it requires the government to justify why some businesses receive direct support while others do not. The question is whether public capital, price guarantees, and targeted financing can be governed transparently enough to survive partisan oversight and scrutiny. In February 2026, lawmakers demanded more transparencywarning that the state could pick winners and losers – for which taxpayers would bear the downside risk. This dynamic means that measures to shape the market require a legitimate and solid justification, beyond money.
Credibility is also tested by the ability of price support to become repeatable. The deal with MP Materials gives investors confidence because a price floor reduces the risk that non-Chinese production will collapse when prices fall. But an exceptional agreement does not create a market. In January 2026, Washington took a step back broader plans for price floors for critical minerals due to funding limits and the difficulty of setting market prices. The result showed a potential gap between the ambition to shape the market and market realities. The question now is how the U.S. government can make price supports a repeatable and reliable policy tool.
The credibility problem also extends to buyers. Public support can make production possible, but it alone cannot create a sustainable market for non-Chinese rare earths. Downstream companies must be prepared to view secure supply as a normal supply requirement, not just a temporary response to Chinese export controls. Apple $500 million deal with MP Materials is important because it transforms supply chain security into a long-term purchasing commitment. But this is still only a high-profile case. If most buyers revert to a cheaper China-linked deal when tensions ease, U.S. price support will have to carry too much of a burden. A sustainable rare earth market requires private demand to share the cost of resilience, rather than leaving it entirely to the state.
Finally, credibility depends on industrial execution. Rare earth resilience requires usable capabilities across supply chain nodes and coordination with allies. Project vault and the Critical Minerals Framework between Japan and the United States show that Washington is trying to build this broader architecture rather than relying on a single company. But the target is moving.
The challenge is not only to catch up with China’s existing capacity, but also to cope with a shifting border. China’s lead is strong in most stages of the value chain, and its integrated industrial base allows it to continue to modernize while its competitors still try to strengthen their core capabilities. The test, therefore, is whether policy commitments can survive the long period between announcement and commercially usable offer.
These risks are interconnected. Political and legitimate controversies can weaken the credibility of price support; uncertain price support can discourage private financing; low buyer commitment can make projects less profitable; slow industrial execution can make public support appear wasteful. In this case, the sustainability problem is cumulative.
In conclusion, the real test of US rare earth strategy is not whether it can replicate China’s entire rare earth system in the near term. The strategic value of Washington’s approach lies in creating a credible external option. While this option remains temporary, concentrated on a few politically exposed companies and subject to reversal, Beijing’s conditional access will continue to shape market expectations. But if Washington can make alternative supplies transparent and predictable, the rare earths industry could become a model for how a market economy builds strategic supply chains without simply copying China’s state-run system.
Durability testing is not just about mines or magnets. More broadly, it is a question of whether a temporary geopolitical scare can be transformed into a governed market that private actors trust.
