CleanSpark Secures $6.6B 20-Year Data Center Lease in Georgia

CLSK shares surged as much as 22% after the company announced a 20-year infrastructure lease worth $6.6 billion tied to a data center at its Sandersville, Georgia campus. The tenant, described only as a 'high investment-grade global technology company,' is expected to anchor an initial 175 megawatts of critical IT load, with deliveries beginning in the fourth quarter of 2027.

The deal marks a pivotal step in CleanSpark's shift from a pure-play bitcoin miner toward AI and cloud data center infrastructure, a pivot several bitcoin-mining peers have also pursued as power-dense sites become valuable real estate for AI compute. The lease is structured to generate roughly $6.6 billion in contracted revenue over its initial term, with the potential to grow as high as $11.6 billion if two five-year extension options are exercised, and the project is expected to contribute a meaningful share of annual net operating income at a near-full margin.

Analysts responded favorably. Cantor Fitzgerald raised its price target on the stock, citing the strategic value of shifting toward long-duration data center leases and away from the more volatile economics of bitcoin mining. The same tenant has also signed a letter of intent covering CleanSpark's entire Texas land portfolio, hundreds of acres with room for further build-out, suggesting Sandersville could be the first phase of a much larger relationship rather than a standalone deal.

For investors, the lease reduces near-term revenue uncertainty by locking in a long-duration contract with a presumably creditworthy counterparty, but it also ties up capacity for two decades in a fast-moving industry. Whether the higher multiple the market is now applying to CleanSpark holds may depend on how quickly the company can convert this and future leases into recurring, high-margin cash flow, and whether AI-driven demand for data center capacity remains strong through the 2027 delivery window and beyond.
