Ulysses Site
Project of Cipher Mining
Where it stands
Cipher Mining acquired the 200 MW Ulysses data center site in Ohio in December 2025, with power capacity secured from AEP Ohio and land options on about 195 acres. As of the February 2026 10-K, the site was expected to energize in the fourth quarter of 2027. The 10-K describes it as suited for HPC and does not mention any construction or operating capacity. The passages do not include any later update.
