What MARA Holdings, Inc. does
In the company’s own words
MARA Holdings, Inc. (NASDAQ: MARA) operates as an energy and digital infrastructure company focused on acquiring, managing, and allocating energy to its highest-value uses. The company maintains its website at www.mara.com.
The company's core business centers on Bitcoin mining as a flexible, energy-responsive workload to monetize excess and underutilized power while optimizing power management across its portfolio. MARA operates approximately 1.9 gigawatts of total capacity across 18 data centers spanning four continents in North America, the Middle East, Europe, and Latin America. As of December 31, 2025, the company operated approximately 490,000 mining rigs globally with an energized hashrate of approximately 66.4 exahashes per second and mined 8,799 bitcoin during the year. The company holds approximately 53,822 bitcoin as of December 31, 2025, valued at approximately 4.7 billion dollars based on year-end spot prices.
Beyond Bitcoin mining, MARA is developing artificial intelligence inference and high-performance computing capabilities within its existing infrastructure footprint. The company acquired a majority ownership interest in Exaion, a company specializing in HPC data centers and secure cloud and AI infrastructure. Additionally, MARA entered into a strategic agreement with Starwood Digital Ventures to jointly develop, finance, and operate AI and HPC infrastructure on select power-rich sites within its portfolio, with potential to provide more than 1 gigawatt of initial IT capacity expanding to more than 2.5 gigawatts over time.
The company has strategically transitioned from an asset-light model to an energy and digital infrastructure company, with approximately 70 percent of operating capacity now representing owned and operated sites. MARA's owned portfolio includes major facilities in Central Texas, East Ohio, North Texas, Central Ohio, Central Nebraska, and international locations. The company also maintains hosted mining operations across five third-party sites.
As of December 31, 2025, MARA employed approximately 266 full-time employees located in the United States and the United Arab Emirates across accounting, communications, engineering, finance, human resources, information technology, legal, and operations functions. The company's strategy emphasizes ownership and control of energy and digital infrastructure to enhance operating control, improve margin durability, and support long-term capital efficiency as demand for energy-optimized compute infrastructure accelerates.
