CleanSpark Jumps 12% on $6.6B Data Center Lease While Riot, MARA, Hut 8 Edge Higher

A CleanSpark data center lease so large it dwarfs the company's own market cap sent shares surging Tuesday, while every peer miner sat frozen on the sidelines, raising one urgent question about what comes next.

Shares of CleanSpark (NASDAQ:CLSK | CLSK Price Prediction) are up 12% to $13.85 in Tuesday morning trading after the Bitcoin (CRYPTO:BTC) miner disclosed a long-duration data center lease that dwarfs its current market capitalization. The move is idiosyncratic, as CleanSpark’s peer miners are barely moving on the day.

CleanSpark stock is now trading above its $12.22 prior close, though shares were down 25% over the past month heading into today’s news. The company is still primarily a Bitcoin miner, with 1.8 GW under contract and a 50 EH/s hashrate as of May, but management is aggressively pivoting toward data center infrastructure.

Sandersville Lease Fuels the Rally

CleanSpark signed a 20-year infrastructure lease with a confidential “high-investment-grade global technology company” at its Sandersville, Georgia campus. The deal covers 175 MW of critical IT load and is expected to generate roughly $6.6 billion in contracted revenue, with two five-year extension options that could lift the total to about $11.6 billion.

It’s structured as a triple-net lease expected to add approximately $330 million in average annual net operating income. CEO Matt Schultz called it “a transformational moment… our evolution into a diversified digital infrastructure platform.” The same tenant also signed a letter of intent covering CleanSpark’s entire 718-acre Texas portfolio, up to 885 MW.

Two caveats matter. Deliveries do not begin until the fourth quarter of 2027, so the revenue impact is a 2027-and-beyond story. The workloads have not been officially labeled as AI or high-performance computing (HPC) by CleanSpark, and the Texas piece remains a letter of intent rather than a signed lease.

Peers Sit Out the Rally

The contrast with CleanSpark’s peers underscores that this is a CleanSpark-specific catalyst. Shares of Riot Platforms (NASDAQ:RIOT), MARA Holdings (NASDAQ:MARA), Hut 8 (NASDAQ:HUT), and HIVE Digital Technologies (NASDAQ:HIVE) are either flat or up slightly today.

Bitcoin itself is only modestly higher. The iShares Bitcoin Trust (NASDAQ:IBIT) ETF is up 3% to $36.40, tracking spot Bitcoin rather than these miners. Single-asset crypto exposure carries its own volatility profile. For context, Riot’s most comparable deal, its Advanced Micro Devices (NASDAQ:AMD) lease at Rockdale, carries $636 million in total contract value over 10 years, an order of magnitude smaller than the CleanSpark headline.

Weighing the Bull and Bear Cases

The bull case for CleanSpark stock is a long-duration, high-margin contracted revenue stream anchored by an investment-grade tenant, with a credible power-to-data-center pivot supported by 585 MW of Electric Reliability Council of Texas (ERCOT)-approved capacity. The bear case is the 2027 revenue start, CleanSpark’s heavy financing needs, potential equity dilution, and execution risk on a lease valued at roughly 2.1x the company’s current market capitalization.

Short interest sits high at 33%, and sentiment on CleanSpark had turned bearish heading into today. Given the stock’s beta of 3.84, position sizing matters here. The analyst target price on CleanSpark stock sits at $21.12, well above current levels.

What to Watch Now

CleanSpark’s ability to finance Sandersville construction without heavy dilution is the next hurdle. Investors can watch for updates on the Texas letter of intent converting to a signed lease, and for whether today’s gains hold into the close given the stock’s short interest and volatility profile.

The financing path is a major concern for CleanSpark. A large equity raise could pressure shares even as the contracted revenue stream builds, while debt financing against the lease could preserve upside but add balance-sheet risk. Either way, the market will be watching how management structures the capital stack for Sandersville.

Peer positioning is the other angle to track. If Riot, MARA, or Hut 8 announce comparable hyperscaler leases in the coming quarters, today’s CleanSpark premium could compress. For now, though, CleanSpark stands alone with a signed deal of this scale, and that scarcity value is what the market is repricing today.
