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.
Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 6 months: -3.28M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
