Bitcoin miner TeraWulf signs $19B, 20-year AI data-center lease with Anthropic

Bitcoin miner TeraWulf has signed a 20-year, $19 billion data-center lease with AI company Anthropic at a campus in Kentucky. The deal marks a major pivot for the former pure-play bitcoin miner, which will now host Anthropic's AI infrastructure. TeraWulf is the latest crypto-adjacent firm to swap the volatile mining business for the steadier revenue of AI data-center services.
