Copper's AI Boom Powers Australia's Mining Rally as Demand Surges

Australia's mining stocks are extending a broad rally fueled by surging copper demand tied to artificial intelligence infrastructure and power grid expansion, analysts say, shifting investor focus beyond the sector's traditional iron ore dominance. Global copper consumption is projected to grow from approximately 28 million tonnes in 2025 to more than 42 million tonnes by 2040—a roughly 50% expansion driven by electrification, renewable energy systems, and AI data center buildout. This structural demand shift is creating a sustained bull case for Australian miners as the world's largest copper producer, BHP Group, along with Rio Tinto and other regional operators, position themselves to capture rising commodity prices.
