CleanSpark signs $6.6B data center lease

CleanSpark, a Nasdaq-listed bitcoin miner, announced on July 14, 2026, that it has signed a 20-year triple-net infrastructure lease with an undisclosed high-investment-grade global technology company at its Sandersville campus in Georgia. The lease covers 175 megawatts of critical IT load and is expected to generate $6.6 billion in contracted revenue over the initial term, potentially reaching $11.6 billion if two five-year extension options are exercised. The tenant will deploy infrastructure for AI and high-performance computing workloads. Additionally, the tenant signed a letter of intent and exclusivity arrangement covering CleanSpark's entire United States — Texas portfolio of 718 acres with up to 885 megawatts of power capacity. CleanSpark's stock surged approximately 10% following the announcement. This deal marks CleanSpark's first data-center lease since its pivot from pure-play bitcoin mining to AI computing in October 2025. The company controls over 1.8 gigawatts of total power capacity. Construction costs are estimated at $10-12 million per megawatt, implying a buildout cost of $1.75-2.1 billion for the Sandersville site. The lease is seen as a validation of CleanSpark's strategy to become a digital infrastructure provider, following similar moves by other bitcoin miners like Core Scientific and TeraWulf.
