Backers

No backer on file. That means no tracked fund's portfolio or Form D names this company — not that it is unbacked.

Thesis

Cipher Mining is a US company in the crypto & blockchain layer of the AI compute stack. Management leaned into the theme on recent earnings calls — 2 AI and 14 data-center mentions across 1 release in the trailing two quarters.

Risk: Like most of the crypto & blockchain layer, the AI narrative is additive rather than core — if AI capex slows, the stock trades on its legacy business, not the theme.
