Bitcoin miners pivot to AI infrastructure amid massive capital spending

Bitcoin mining companies are undergoing a significant strategic pivot toward artificial intelligence and high-performance computing (HPC) to leverage their existing power infrastructure. According to CoinShares, publicly listed miners could see AI-related revenue rise from approximately 30% this year to 70% by December 2026.

This transition involves massive capital expenditures. A group of 15 miners and AI data center operators invested $30.7 billion in capital assets during recent 2026 reporting periods, a 42.6% increase over 2025. However, revenue from AI and HPC services currently lags behind these investments; a subset of nine comparable miners reported a 15-to-1 ratio between capital expenditures and AI-related earnings in the first half of the year.

Individual companies are securing major contracts to facilitate this shift. IREN reported that its AI cloud revenue reached $70.5 million in its fiscal fourth quarter, surpassing its Bitcoin mining revenue for the first time. IREN also secured a GPU cloud contract with Microsoft valued at approximately $9.7 billion over five years. Other notable players include Core Scientific, which has a $10.2 billion partnership with CoreWeave, TeraWulf with over $12.8 billion in contracted HPC revenue, and Hut 8, which signed a $7 billion lease backed by Google.
