Why the US Is Pushing to Rebuild Its Copper Supply - Wall Street Week
Apr 19, 2026
As demand for electricity surges in the age of artificial intelligence, copper has become a critical input for everything from data centers to power grids. But US production has stagnated for decades, leaving the country increasingly reliant on imports even as global demand accelerates. In Arizona, projects like Rio Tinto’s Resolution mine highlight both the scale of untapped domestic resources and the challenges of bringing new supply online, from regulatory delays to rising costs. With China dominating processing and global competition intensifying, industry leaders and analysts warn that rebuilding US copper capacity is not just an economic priority, but a strategic one.
