U.S. Offtake Agreements in Africa: What They Do and What They Don’t

China controls 92% of the world’s rare earth processing and 80% of its cobalt refining. Yet Washington’s central response to that grip is not a mine, a refinery, or a trade embargo. It is a contract.

The instrument at the heart of the strategy is the offtake agreement, and it is being deployed in real time across the African continent. The Democratic Republic of Congo (DRC) joint venture between Mercuria and Gécamines became operational in April 2026. The $553 million Lobito Corridor loan was finalised in December 2025. The Kenya framework, meanwhile, remains advanced but unsigned as of September 2026. This is an active, unresolved contest, not a future scenario.

This piece explains the mechanism actually being deployed, how it is performing against China’s entrenched position, and what the unresolved tensions in the strategy mean for anyone tracking critical minerals supply chains.

What an offtake agreement actually does, and why Washington chose this tool

Start with the mechanism itself. An offtake agreement grants a buyer the right to purchase a predetermined share of a mine’s future production in exchange for upfront financing or other committed support. The deal is struck before a single tonne of ore leaves the ground.

That timing matters. The buyer commits to purchasing output that does not yet exist, and in return the mine gains something more valuable than cash alone: revenue certainty. That certainty substitutes for traditional collateral, which is what turns an offtake into a financing lever as much as a procurement tool.

An offtake agreement therefore does three things at once:

• Guarantees a buyer a secured share of future mineral supply
• Functions as a financing instrument, unlocking blended finance and private capital that direct equity investment cannot easily reach
• Redirects where mineral output flows geopolitically, steering it into buyer-aligned value chains

Now the strategic logic. Africa holds an estimated 30% of global critical mineral reserves, which is why the continent is the terrain on which this contest plays out. But the deeper reason for choosing offtakes lies in where China’s dominance sits.

China’s processing grip Lithium: 71%. Cobalt: 80%. Rare earths: 92%. Graphite: 96%.

Those figures tell you something specific about what the United States can and cannot do. It cannot win a short-term competition in refining infrastructure, where China is structurally entrenched. So the offtake model is a deliberate workaround: rather than out-investing China at the processing stage, Washington is trying to redirect where output flows after it leaves the mine.

The asymmetry that offtakes are designed to partially compensate for is stark. In 2023, Chinese critical mineral investment in Africa reached $8-10 billion. U.S. investment that same year was roughly $300 million.

For anyone tracking supply chain realignment, the distinction is the whole point. An offtake is not equity ownership, an extraction licence, or a trade agreement. It is a lower-cost, faster-to-execute intervention, and understanding that shapes what kind of supply chain security it can realistically deliver.

The DRC deal in practice: Mercuria, Gécamines, and 500,000 tonnes of copper

The clearest live example of the model at scale sits in the DRC. On 5 December 2025, commodity trader Mercuria and Congolese state miner Gécamines announced a copper- and cobalt-focused metals trading joint venture, built to commercialise Gécamines’ equity share of production and channel it toward U.S. and allied buyers.

The structure blends private capital with government backing. Mercuria is providing up to $1 billion in financing facilities to the venture, combining pre-financing and offtake funding. Sitting behind the commercial parties is the U.S. International Development Finance Corporation (DFC), whose support gives the arrangement its geopolitical weight.

Watch how the volume commitments moved. The DRC initially pledged 100,000 tonnes of copper to the U.S. market. That commitment was subsequently raised to 500,000 tonnes for U.S. and allied buyers over a multi-year period, with a further 50,000 tonnes of copper cathode committed to Saudi Arabia and the UAE.

That jump from 100,000 to 500,000 tonnes is not a rounding error. It signals that DFC backing gave the commercial parties enough confidence to scale their ambition fivefold, and it tells you what government-backed financing adds to these structures beyond political optics.

Crucially, the venture markets output that would otherwise flow to Chinese refiners, and it does so without the United States building or operating a single mine.

Why the DFC’s role changes the risk calculus

DFC backing provides political-risk coverage that a private trader acting alone cannot offer. That coverage lowers the threshold at which private capital is willing to enter a high-risk jurisdiction, which is precisely why the commitment could scale so quickly.

The blended structure also changes the accountability dynamic. A deal combining a development finance institution, a private trader, and a state-linked counterparty is more resilient to sudden sovereign policy shifts than a purely commercial arrangement, because no single party can unwind it unilaterally.

Infrastructure as offtake enabler: the Lobito Corridor and the Orion Consortium

An offtake agreement is only as valuable as the infrastructure that moves the mineral. A committed buyer means little if the ore cannot reach a port at a competitive cost, and Washington appears to understand this.

The clearest evidence is the Lobito Corridor, roughly 1,300 km of railway connecting the Copperbelt regions of the DRC and Zambia to Angola’s port of Lobito. The route is designed to cut both the cost and the journey time of exporting copper, cobalt, and lithium relative to existing options.

The U.S. financing engagement runs across three distinct layers:

1. Direct railway financing: the DFC finalised a $553 million loan to Angola’s Lobito Atlantic Railway in December 2025, part of a larger $753 million package that includes $200 million in co-financing from the Development Bank of Southern Africa (DBSA)
2. Multilateral consortium capital: the Orion Critical Mineral Consortium, mobilising private and Gulf capital alongside American institutional backing
3. Project-level direct investment: a $3.4 million DFC commitment to Pensana’s Longonjo rare earth project in Angola

Scale of the ambition The corridor upgrade is expected to lift transport capacity ten-fold to 4.6 million metric tonnes annually.

The financial impact runs deeper than raw tonnage. The upgraded corridor is expected to reduce the cost of transporting critical minerals by up to 30%, and a cost reduction of that magnitude changes which projects are commercially viable in the first place.

That is the point investors should hold onto. Infrastructure financing here is not a soft diplomatic gesture. It is a direct intervention in the economics that determine whether an offtake agreement becomes self-sustaining or stalls before the first shipment.

The Orion Consortium and the multilateral financing model

The Orion Critical Mineral Consortium brings the DFC together with Orion Resource Partners and Abu Dhabi’s ADQ. It is a deliberate coalition-building exercise, drawing Gulf capital into the African minerals contest rather than leaving the United States to act alone.

So far the consortium has mobilised nearly $2 billion, with a stated target of $5 billion. That expansion goal signals an intent to move well beyond the DRC and Angola into broader African producer geographies, which tells you the strategy is being built for scale rather than as a one-off intervention.

Kenya, sovereignty, and the terms African governments are extracting

Flip the perspective from Washington to Nairobi and the contest looks different. African governments are not passive recipients of great-power competition. They are active negotiators, and Kenya is the clearest current example of that leverage in action.

At the G7 summit in Évian-les-Bains, Kenyan President William Ruto disclosed that a shared understanding had been reached whereby minerals would be processed domestically within Kenya rather than exported raw for overseas refinement. U.S. officials, including Frank Garcia, Assistant Secretary of State for Africa, and Chris Kulukundis, Acting Deputy Assistant Secretary of State for Southern Africa and Critical Minerals, confirmed the two governments had reached common ground on advancing the sector.

Washington framed its approach around transparency, community respect, and local value retention.

Washington’s positioning The U.S. has emphasised sector transparency and keeping value-added processing in-country, contrasting this directly with the practice of extracting raw minerals and conducting all refining abroad.

As of September 2026, the framework remains advanced but unsigned. No treaty, contract, or finalised text has been publicly confirmed, which means genuine implementation risk still sits between the political understanding and a bankable agreement.

That unsigned status is not a failure. It reflects that African governments have grown sophisticated enough to hold out for terms serving their own processing ambitions, and it is part of a broader structural pattern. Across the DRC, Zambia, Guinea, and Kenya, sovereign demands are being written directly into offtake and corridor agreements:

• In-country processing requirements that keep refining and value addition on home soil
• Local content and employment obligations tied to project approval
• Infrastructure co-investment conditions attached to export access

For investors, the reframing matters. A country demanding local processing is not a deal risk to be managed around. It is a structural shift in how African mineral agreements are being constructed across the board, and future announcements should be read with that in mind.

What the strategy can and cannot deliver for supply chain security

The honest assessment comes last. The offtake model is a genuine strategic innovation, and the progress is real: the DRC deal operational, the Lobito Corridor financed, the Orion Consortium capitalised, and the Kenya framework advanced. Together these represent a materially different posture from pre-2025 U.S. engagement in African minerals.

But the model hits a ceiling. It redirects where minerals go after extraction. It does nothing to address China’s dominance in processing and refining, which means U.S.-aligned supply chains still depend on Chinese infrastructure for value addition unless parallel refinery investment follows.

The implementation gap is the primary risk. Announcements routinely precede legal closure and operational reality by years, held up by infrastructure bottlenecks, permitting delays, and sovereign risk. The Kenya framework’s unsigned status is the live illustration.

There are structural cautions too. Analysts and civil-society groups warn that long-term take-or-pay clauses can limit producer upside during commodity booms, while corridor infrastructure carries displacement risks and international arbitration exposure.

The sovereignty risk Long-term take-or-pay clauses and fixed-price structures can cap producer upside during a boom and restrict future policy flexibility, routing disputes to international arbitration.

The read you should take from this is measured. Offtake agreements are a necessary but not sufficient condition for genuine supply chain independence. Anyone leaning on “supply chain security” language in an investment thesis should be asking whether the refinery piece is in place before the offtake volume commitment means anything at all.

Reading the deal announcements that matter, and the ones that do not

After the mechanism, the live cases, the infrastructure, and the limits, the practical question is how to separate signal from noise. Both operational progress and aspirational frameworks are being announced simultaneously, and both are described in official communications using similar language.

A simple three-question filter cuts through it:

1. Is there a signed volume commitment, with a defined tonnage over a defined period?
2. Is there confirmed financing with named institutional parties behind it?
3. Is there an operational or legal-close date that has actually been declared?

Apply that filter to the two anchor cases and the difference is obvious. The DRC-Mercuria deal passes on all three: signed, operational since April 2026, a $1 billion financing facility, and a 500,000-tonne commitment confirmed. The Kenya framework, advanced and substantive as it is, remains unsigned as of September 2026 and therefore fails the first and third tests.

The infrastructure pieces sit in between. The Lobito Corridor’s $553 million DFC loan was finalised in December 2025, but the operational upgrade is still in progress. The Orion Consortium has mobilised nearly $2 billion toward a $5 billion target and remains active.

The broader implication is that the U.S. strategy is real, gaining momentum, and already reshaping how African producer governments negotiate with every partner, China included. But the processing gap means genuine supply chain independence stays a medium-term project rather than a near-term achievement. Volume committed, financing confirmed, operational status declared: those three questions are what separate real movement from diplomatic positioning.

Financial projections are subject to market conditions and various risk factors, and these forward-looking assessments may change based on geopolitical and market developments.
