The largest single government investment in domestic rare earth production in US history remains unsigned four months after its announcement. USA Rare Earth (Nasdaq: USAR) and the Department of Commerce’s CHIPS Program Office have been working toward definitive documentation on a proposed $1.6 billion funding package since a non-binding Letter of Intent was signed on 26 January 2026 — but as of mid-May 2026, the usa rare earth funding agreement has not been finalised, with USAR’s own guidance slipping from April to May 2026 in successive earnings releases.
USA Rare Earth Funding: What the LOI Covers
The proposed package, drawn from authority under the CHIPS and Science Act, comprises two components: a $277 million direct funding award and a $1.3 billion senior secured loan carrying a 15-year term at an expected rate of Treasury plus 150 basis points. In exchange, the US government would receive 16.1 million USAR common shares and approximately 17.6 million warrants — representing an equity stake estimated at between 8% and 16% depending on warrant exercise.
The CHIPS Program Office confirmed the LOI publicly via the National Institute of Standards and Technology (NIST), describing USAR as “the only company in the US that will mine rare earth-containing critical minerals, extract rare earth oxides, convert them to rare earth metals, and strip-cast these metals as feedstock for the manufacture of neodymium iron boron (NdFeB) permanent magnets.” The proposed funding targets total capital investment of approximately $3.3 billion across two facilities: the Round Top project in Sierra Blanca, Texas, and the Stillwater magnet manufacturing plant in Oklahoma.
Six Conditions USAR Must Meet Before Funds Flow
Funding is milestone-based — not a lump-sum disbursement. USAR disclosed in its S-1 registration filing six conditions precedent to entering definitive documentation:
| Condition | Status (May 2026) |
|---|---|
| Raise at least $500m from non-federal sources | ✅ Met — $1.5bn PIPE closed January 2026 |
| Obtain two MOUs from semiconductor end or midstream users | ⏳ Not publicly confirmed complete |
| Obtain NdPr oxide and MREC feedstock supply agreements through at least 2027 | ⏳ Not publicly confirmed complete |
| Exercise surface purchase option with Texas General Land Office | ⏳ Not publicly confirmed complete |
| Implement third-party nuclear material licensing recommendations at Wheat Ridge, Colorado | ⏳ Not publicly confirmed complete |
| Define power infrastructure plan for Stillwater magnet facility | ⏳ Not publicly confirmed complete |
The $277 million grant component carries an additional condition: USAR must issue shares to the US government as part of the direct funding award, which is the provision at the centre of congressional scrutiny. Once definitive agreements are signed, funding flows as USAR incurs and evidences qualifying capital expenditures — not as an upfront payment.
Congressional Scrutiny: The Equity Stake Controversy
In March 2026, Representative Zoe Lofgren — ranking member of the House Committee on Science, Space, and Technology — wrote to Commerce Secretary Howard Lutnick describing the deal as “highly concerning.” The central objection was a provision in the regulatory filings allowing the federal government to retain its equity stake even if the funding is withdrawn or clawed back due to missed milestones. Lofgren called this “deeply strange,” arguing it creates a structure with no precedent in established government investment practice.
A secondary concern centred on Cantor Fitzgerald, which led the concurrent $1.5 billion PIPE financing. Cantor Fitzgerald’s chairman is Howard Lutnick — the same individual as the Commerce Secretary overseeing the DOC funding package. USAR CEO Barbara Humpton defended the arrangement in April 2026, saying the company’s “best move was to go with the team who knew us.” The Commerce Department declined to respond to requests for comment at the time.
The House Committee requested document production from the Commerce Department by 3 April 2026. A separate Senate committee review of at least one other federal equity deal in the critical minerals sector was also reported. No subpoenas have been enforced as of May 2026. The scrutiny caused USAR shares to fall 8.8% on 20 March 2026, when Lofgren’s letter became public, on trading volume 175% above the 20-day average.
Strategic Context: Why the Funding Matters
The DOC package is the cornerstone of USAR’s capital structure for its mine-to-magnet buildout. The company’s $1.75 billion cash position (as of 31 March 2026) is sufficient to fund near-term operations and the Stillwater ramp, but the full Round Top development — targeting 40,000 metric tonnes per day of feedstock by 2030 — requires a capital base of several billion dollars. The proposed CHIPS loan, at Treasury plus 150bps, is substantially cheaper than commercial debt financing for a pre-production mining asset.
The strategic rationale for the funding is grounded in China’s processing dominance. China controls roughly 85–90% of global rare earth separation and refining capacity, and has demonstrated willingness to use export restrictions as a policy lever — as detailed in the China rare earth export controls analysis. Round Top’s heavy rare earth output — including dysprosium and terbium, for which no US domestic source currently operates at commercial scale — addresses the most acute supply chain vulnerability in the NdFeB magnet supply chain.
For investors tracking the deal’s progress, the USAR earnings call of 13 May 2026 confirmed the Q1 earnings transcript language: the company described itself as “on the brink of signing” the definitive agreement. See also the USA Rare Earth Q1 2026 results for the full financial context.
What to Watch
The signing of the definitive funding agreement is the single most important near-term catalyst for USAR. When signed, it will constitute a material event triggering an 8-K filing — making it immediately trackable. The outstanding milestones (semiconductor MOUs, feedstock supply agreements, Texas GLO surface option, nuclear licensing, power plan) represent the remaining preconditions. Any congressional escalation — from document requests to formal subpoenas — represents the primary downside risk to the deal timeline. USAR’s next scheduled disclosure is the annual meeting on 3 June 2026, followed by an Investor Day before Q3 2026.

What is the USA Rare Earth $1.6 billion DOC funding deal?
The US Department of Commerce’s CHIPS Program Office signed a non-binding Letter of Intent in January 2026 to provide USA Rare Earth (Nasdaq: USAR) with up to $1.6 billion in funding. The package comprises a $277 million direct grant and a $1.3 billion senior secured loan at Treasury plus 150 basis points, in exchange for a government equity stake of between 8% and 16% (16.1 million shares and approximately 17.6 million warrants).
Has the USA Rare Earth DOC funding agreement been signed?
As of mid-May 2026, no. The Letter of Intent was signed on 26 January 2026, but definitive documentation has not been finalised. USAR guided completion by April 2026, then May 2026. On its Q1 2026 earnings call, CEO Barbara Humpton described the company as “on the brink of signing.” The agreement would trigger an SEC 8-K filing when executed.
What conditions must USA Rare Earth meet before receiving the CHIPS funding?
USAR disclosed six preconditions in its S-1 filing: raising at least $500 million from non-federal sources (met via the January 2026 PIPE); securing two semiconductor end or midstream user MOUs; obtaining NdPr oxide and MREC feedstock supply agreements through at least 2027; exercising a surface purchase option with the Texas General Land Office; implementing nuclear material licensing recommendations at its Wheat Ridge, Colorado facility; and defining a power infrastructure plan for the Stillwater magnet plant.
Why is the government taking an equity stake in USA Rare Earth?
The Trump administration has used equity participation as a condition of federal financing across several critical minerals deals, arguing direct ownership aligns government interests with supply chain development outcomes. Under the CHIPS and Science Act’s “other transaction” authority, the Commerce Department structured the deal to include 16.1 million USAR shares and approximately 17.6 million warrants. Congressional critics, led by Rep. Zoe Lofgren, have questioned whether this authority permits equity stakes in private firms.
What projects does the USA Rare Earth DOC funding support?
The proposed $1.6 billion covers two facilities with a combined estimated capital investment of $3.3 billion: the Round Top heavy rare earth project in Hudspeth County, Texas (targeting commercial production in 2028 and 40,000 metric tonnes per day throughput by 2030), and the Stillwater, Oklahoma magnet manufacturing plant (Phase 1a commissioned March 2026, targeting 1,200 MTPA of NdFeB magnet capacity by Q1 2027).
