Rare earths: rebuilding the supply chains powering the future | The Next Big Thing

Rare earths are no longer just a niche mining story. They sit at the centre of some of the most important trends shaping the global economy, from electric vehicles and robotics to AI infrastructure, drones and defence systems. Yet the real challenge is not simply finding these materials. It is building the supply chains needed to process them and turn them into the products modern industry depends on. In this episode of The Next Big Thing, we speak with Ryan Corbett, Chief Financial Officer of MP Materials, about the race to rebuild rare earth supply chains. We explore China's dominance across mining, refining and magnet production, why NdPr is emerging as a critical bottleneck, and why demand is broadening well beyond electric vehicles. The conversation also examines the role of industrial policy, supply chain security and vertical integration in building a resilient materials ecosystem.
