Who's buying in critical minerals

Serious money arrived in this sector while almost nobody was watching, and it came through two doors that look alike and aren't. If you own a business anywhere near this supply chain, one of these buyers may already be circling your category.

Last updated 2 August 2026. This page is maintained, not archived.

I keep this list because capital flows tell you what people actually believe. Anyone can write an opinion about where this sector is going. A deal is a conviction with a price attached to it, which makes it better evidence.

The first door is opportunistic. Roll-ups in testing, inspection, certification and compliance are sweeping up minerals-adjacent firms as part of a broader mid-market consolidation wave that has nothing to do with rare earths specifically. These buyers aren't expressing a view on minerals. They're buying services businesses that happen to serve this customer, and they'd buy the same firm if it served food processing.

The second door is deliberate. Sponsors are becoming the preferred vehicle for deploying government critical-minerals capital. Sponsor money blended with sovereign wealth and development finance in purpose-built consortia. This one is newer, much larger, and moving fast.

Most coverage treats them as the same phenomenon. They are not, and confusing them will lead you to the wrong conclusion about who is likely to knock on your door.

Sorted chronologically. Transition Equity Partners and 1789 Capital behave like sponsors without being traditional buyout funds: concentrated checks, board involvement, exit-oriented.

Where the money is concentrating

1. Compliance and testing roll-ups

KKR/ERM, Blackstone/Alliance Technical, GenNx360/NVI. This is the least minerals-specific pattern of the three. It's a broader consolidation wave in environmental and industrial compliance services that catches minerals-adjacent firms because testing demand tracks total industrial activity, not any single commodity.

Read it as a real ownership signal for the services layer. Don't read it as evidence of a rare earth thesis.

2. Government-anchored consortia

The largest and most minerals-specific cluster, and it's growing fast. Orion Resource Partners has built an actual platform: the Abu Dhabi JV, the $1.8B consortium with DFC as a $600M anchor LP, and the Saudi partnership with SNB.

The Pentagon's July 2026 National Security Fund Finance program is the clearest signal yet that this model is becoming default. Rather than DoD staff underwriting deals directly, as they did with MP Materials and USA Rare Earth, the government is routing up to $100B through private fund managers. Because sponsor-style sourcing and diligence covers more ground than government staff can.

That converts PE from an occasional opportunistic buyer here into the primary channel for government minerals capital.

3. Downstream venture hybrids

Smaller and newer. 1789 Capital backing Vulcan Elements with a stated intent to review 20+ targets across rare earths and defense tech. Transition Equity's $200M facility for ReElement's toll-processing model.

Both behave more like late-stage growth equity than buyout. Concentrated bets on single operating companies rather than platforms. But both are sponsor capital, not strategic or government money.

Strategics that get mistaken for sponsors

These surface in the same searches and are easy to misclassify. None are financial buyers. Each is a signal about where consolidation pressure is building.

The move that isn't a transaction

The ERI and Cyclic Materials partnership deserves separating out, because it's the most instructive thing on this list and it wouldn't appear in any deal database.

No change of control. No price. Two companies simply agreed that one would sort magnet-heavy material across eight US recycling facilities and ship the concentrate to the other's Arizona hub, and that they'd bid contracts together.

The effect is that a meaningful share of US end-of-life magnet feedstock is now spoken for, without anyone buying anything. Nobody can outbid a partnership. There is no auction to enter and no owner to approach.

Exclusivity by agreement forecloses a supply chain faster and cheaper than acquisition, and leaves no entry point behind it.

If you're watching a category for consolidation, watching only for deals will make you late. Offtakes, exclusive supply agreements and joint bids do the same work and generate no filing.

What I'd watch

The Pentagon fund finance program is the single most consequential item here. If it scales as intended, it expands both deal volume and the number of sponsors actively underwriting minerals-adjacent risk. Orion is the clearest first mover and the name most likely to appear again.

On the compliance services side, expect continued roll-up activity. Treat it as a services-sector trend rather than a minerals thesis unless a deal explicitly names minerals revenue.

What this list is missing. Deals below roughly $50M enterprise value, which is most of them. Sponsors at that size don't issue press releases and the targets don't file. I built this from public announcements, which systematically overweights large, marketed transactions.

The absence of small deals in this table is not evidence that small deals aren't happening. If you know of one, I'd like to hear about it.

What this means if you own a business

Strip out the fund names and the practical read is short.

Somebody with more capital than you is probably looking at your category. If you're in testing, inspection, certification, calibration, environmental compliance or industrial services touching this supply chain, there is an active consolidation wave and you are in it whether or not anyone has called yet.

That is mostly good news for you. More buyers means better prices and more options. The owners who got hurt in previous consolidation waves weren't the ones who sold. They were the ones who waited until a platform had already bought their three nearest competitors and no longer needed them.

The buyer matters more than the price. A sponsor with a five-year fund clock, a strategic wanting your customer list, and someone who intends to operate the business are three completely different outcomes for your employees and your name on the building. That difference rarely shows up in the headline number.

Know of a deal that belongs on this list? Send it and I'll add it. Small deals especially. They don't get announced and this list is systematically missing them.

Getting approached and not sure what to make of it? Happy to give you a read on who's calling and what it likely means. No agenda, and I'll say so if I'm interested in the business myself.
