TeraWulf (WULF) jumped 13% on Tuesday after unveiling plans for the Muskie Data Campus, a hyperscale AI and high-performance computing (HPC) site in Kentucky capable of supporting more than 1 gigawatt of capacity. The project is staged in two phases: an initial 500 megawatts targeted for delivery in the second half of 2028, with another 500 megawatts planned by 2030. The company framed the build as a pivot from pure bitcoin mining toward AI infrastructure, where power and land — not GPU supply — increasingly determine which operators get built.
Why it matters
The move lands in the middle of a wider repricing of former bitcoin miners as AI infrastructure plays. Hut 8 (HUT) climbed 7%, Keel Infrastructure (KEEL, formerly Bitfarms) rose 6.5%, IREN gained nearly 5%, and Cipher Mining (CIFR) advanced 5.5% in sympathy. TeraWulf CEO Patrick Prager used the announcement to argue that the binding AI constraint has shifted: "The defining constraint in this market is no longer computing hardware. It is power, transmission infrastructure, and execution certainty." It's a thesis the sector has been building toward for a year — that miners' grid interconnects and power-purchase agreements are more strategically valuable in an AI world than the rigs they were originally built to power.
Market impact
The Kentucky campus is also a bet on geography. Locating 1 gigawatt of AI capacity in a state with relatively cheap power and available land is a different risk profile from sitting on the East Coast or in PJM-territory markets where grid congestion has pushed industrial electricity prices sharply higher. If TeraWulf hits its 2028 initial-power milestone, the project would be one of the larger single-site AI builds outside the hyperscalers' flagship campuses. The rally also tracked fresh highs in AI-adjacent semis: Micron (MU) jumped 15% past $870 after UBS lifted its price target to $1,625 on AI memory demand, and AMD gained 5% to a record.

Why did TeraWulf stock jump 13% on Tuesday?
Shares rose after the company announced the 1GW Kentucky AI build and framed it as a strategic pivot from bitcoin mining toward AI infrastructure. The announcement also lifted former-mining peers Hut 8, IREN, Cipher Mining, and Keel Infrastructure in sympathy.
-
What did TeraWulf CEO Patrick Prager say about the AI buildout?
Prager argued that the binding constraint in AI has shifted away from chips: "The defining constraint in this market is no longer computing hardware. It is power, transmission infrastructure, and execution certainty."
-
Which other bitcoin mining stocks rallied on the AI infrastructure news?
Hut 8 (HUT) climbed 7%, Keel Infrastructure (KEEL, formerly Bitfarms) rose 6.5%, IREN gained nearly 5%, and Cipher Mining (CIFR) advanced 5.5% on Tuesday, tracking TeraWulf's lead.
