MARA Holdings — Energy-Integrated Mining and Heat Reuse

MARA Holdings is a Nasdaq-listed bitcoin miner and energy-infrastructure operator with data centers in the United States and international markets. The company's operations page describes sites connected to solar, wind, hydro, landfill gas, associated gas, and conventional grids, together with immersion and liquid-cooling deployments. MARA has acquired operating data centers and a Texas wind farm, developed modular mining at oil-and-gas locations, and announced a West Texas initiative with MPLX beginning at 400 megawatts of planned generation and data-center capacity. In Finland, its water-cooled systems have been connected to district-heating networks so recovered computing heat can serve local buildings. The portfolio includes owned, jointly operated, hosted, and planned facilities, making a single aggregate megawatt figure difficult to compare across stages. MARA also announced 2026 partnerships to develop its power-rich sites for high-performance computing. Prospective land, power, heat, or hosting counterparties should evaluate each site's ownership, interconnection, fuel contract, emissions treatment, heat-offtake agreement, and energization schedule separately.
