Data center firm Applied Digital has completed the first phase of the second building at its AI and HPC campus in Ellendale, North Dakota.The company this week announced it has achieved ready for service for Phase I of Building 2 at Polaris Forge 1, delivering 75MW of operational capacity to its customer on schedule.The move brings total live capacity at the campus to 175MW. At full build-out, Polaris Forge 1 is contracted to deliver 400MW of critical IT load under long-term lease agreements.“Delivering this phase on time underscores the strength of our execution model,” said Wes Cummins, Chairman and CEO of Applied Digital. “Polaris Forge 1 continues to demonstrate the depth of our team and the discipline it takes to bring critical AI infrastructure capacity online for our customers. Achieving this milestone required intense coordination across the field, construction, engineering, operations, procurement, development, and corporate teams, and I’m proud of the entire Applied Digital organization for delivering as planned. With 175MW now live at the campus, Polaris Forge 1 demonstrates the repeatable model we are scaling across our AI Factory footprint.”Polaris Forge 1 began construction in September 2022 as part of the company’s crypto and HPC business, but all of its capacity will now be taken up by CoreWeave. The neocloud initially signed on for 250MW in June 2025 before increasing the agreement to take up all capacity as part of an $11bn, 15-year agreement. The first phase of Building 1 was completed in December 2025.Applied Digital was founded in 2021 as Applied Blockchain, but is pivoting to developing AI and HPC data centers, and has signed multiple large-scale deals.Applied’s contracted portfolio spans five AI Factory campuses, totaling 1.4GW of critical IT load, and approximately 2.15GW of grid-connected utility power.
