Cipher Digital Inc.

A U.S. data center developer and operator, Cipher Digital builds and runs large-scale facilities for high-performance computing and artificial intelligence work, hosting tenants like Amazon Web Services. It began in 2021 as Cipher Mining, a Bitcoin mining company backed by hardware maker Bitfury, and went public that year through a merger with a special purpose acquisition company. The name comes from "cipher," the cryptography at the heart of blockchain, and the company rebranded as Cipher Digital in 2026 after shifting from mining to data center infrastructure.
