NYDIG (New York Digital Investment Group) is a leading U.S.-based Bitcoin-focused financial services and power infrastructure firm, founded in 2017 as a subsidiary of Stone Ridge Holdings Group. The company operates two vertically integrated franchises: Bitcoin Financial Infrastructure (providing regulated custody, institutional-grade spot/derivatives trading, structuring, financing/HODL loans, and asset management) and Power & Bitcoin Mining (large-scale Bitcoin mining operations leveraging low-cost and stranded energy sources). In March 2025, NYDIG significantly expanded its mining capabilities by acquiring Crusoe Energy Systems' Bitcoin mining business, adding over 270 MW of near-zero-cost power generation technology. NYDIG benefits from synergies with Stone Ridge Energy's >10 GW natural gas production for cost-effective mining. As of December 22, 2025, NYDIG is active with a strong institutional focus, supporting Bitcoin's network security while exploring productive uses of scaled energy.
