BlackRock backs large-scale mining M&A to attract investors and boost supply

BlackRock wants the mining industry to get bigger. Not just in the “dig more holes” sense, but in the corporate restructuring sense, where massive companies merge into even more massive ones to solve problems that smaller players simply can’t.

Olivia Markham, co-manager of BlackRock’s World Mining Trust, made the case for large-scale consolidation during a speech at the Australian Financial Review conference in Perth on May 27. Her argument boils down to a simple thesis: if mining companies want access to US generalist capital, they need to be large enough and liquid enough to show up on those investors’ radars.

The liquidity problem mining can’t ignore

Markham argued that larger, consolidated mining entities would offer precisely the advantages these investors care about: better liquidity, easier capital access, and more favorable trading multiples.

The demand side of the commodity equation is accelerating thanks to three converging forces: electrification, artificial intelligence infrastructure, and defense spending. Each of these requires enormous quantities of metals, and the current supply chain is, in Markham’s assessment, “massively underinvested.”

The implication is straightforward. Prices will need to rise to incentivize new production. And the companies best positioned to develop complex, capital-intensive projects are the ones with balance sheets large enough to absorb the risk.

The $240 billion deal that wasn’t

Earlier in 2026, Glencore and Rio Tinto explored a potential merger that would have created a combined entity valued at roughly $240 billion. Rio Tinto ultimately walked away from negotiations, citing insufficient projected cost synergies.

BlackRock holds stakes in both Glencore and Rio Tinto, as well as BHP, which makes Markham’s advocacy for consolidation more than academic commentary.

Why commodities, why now

Markham also highlighted uranium as a key demand driver, tied to the growing push for energy independence.

All of these demand drivers are colliding with a supply side that has been starved of investment for years. That gap between demand and supply is the core of Markham’s argument. Consolidation creates companies with the scale to finance and execute the complex projects needed to close it.
