TeraWulf Inc. (TeraWulf) operates as a vertically integrated owner and operator of next-generation digital infrastructure, primarily powered by predominantly zero-carbon energy.
The company develops and operates high-performance data centers optimized for both bitcoin mining and high-performance computing (HPC) workloads, leveraging clean, and reliable energy sources to drive long-term sustainability in digital infrastructure. The company’s operations are anchored at the Lake Mariner Facility in upstate New York, strategically located on the shores of Lake Ontario (the Lake Mariner Facility or Lake Mariner). Developed on the site of a decommissioned coal-fired power plant, Lake Mariner is designed for scalable growth, with the capacity to expand up to 500 megawatts (MW) in the near term and 750 MW with certain transmission upgrades.
A key milestone in this transition occurred on December 23, 2024, when the company entered into long-term data center lease agreements with Core42 Holding US LLC, a G42 company specializing in sovereign cloud, AI infrastructure, and digital services, securing 72.5 MW of HPC hosting capacity at Lake Mariner for GPU compute workloads. The lease agreements include an option, exercisable through March 31, 2025, to expand by an additional 135 MW. This marks a significant step forward in the company's HPC hosting strategy, reinforcing its position in the rapidly growing market for artificial intelligence (AI) and machine learning compute infrastructure.
The company primarily operates through two wholly-owned subsidiaries:
Lake Mariner Data LLC – The company operates a fleet of high-performance bitcoin miners, primarily sourced from Bitmain Technologies Limited, to validate transactions on the bitcoin blockchain. As of December 31, 2024, it had an operational self-mining capacity of 195 MW, with an additional 50 MW under construction and expected to come online in the first half of 2025. The company's focus remains on optimizing operational efficiencies to reduce costs and maximize bitcoin production.
Wulf Compute LLC – The company has constructed and is continuing to expand its purpose-built infrastructure to provide HPC hosting and colocation services for GPU-based workloads, AI, machine learning, and cloud computing applications. By leveraging its engineering expertise, scalable infrastructure, and cost-efficient power model, the company aims to become a premier hosting provider for enterprises requiring high-density compute capacity.
Business Strategy
TeraWulf’s strategy is built on leveraging its owned and scalable digital infrastructure to drive revenue and profitability through both bitcoin mining and HPC hosting. As a vertically integrated operator, the company owns and controls its infrastructure.
The company focuses primarily on earning bitcoin through mining and selling the bitcoin generated for cash, activities directly related to growing its digital infrastructure and enhancing efficiencies in its operations (e.g., reducing its cost to mine). While bitcoin mining remains a core focus, the company is strategically shifting an increasing portion of its infrastructure at Lake Mariner to support HPC hosting and colocation, capitalizing on the rapid growth of AI and cloud computing. Its transition to GPU-based workloads is a natural evolution of its platform, originally designed for bitcoin mining and now expanding to accommodate the growing demand for GPU-driven computing. As demand for AI, cloud computing, and machine learning continues to surge, its ability to design, build, and operate large-scale, sustainable data centers uniquely positions it to capitalize on this transformation.
Facilities
TeraWulf conducts its operations at its data center campus, the Lake Mariner Facility, in upstate New York. The company has an operational mining capacity of 195 MW and is completing constructing an additional 50 MW of bitcoin mining capacity, expected to be operational in the first half of 2025. Additionally, TeraWulf is developing HPC data centers to provide hosting services for Core42, supporting up to 72.5 MW of data center infrastructure dedicated to GPU compute workloads. This capacity is expected to come online throughout 2025. Core42 also has an option, exercisable through March 31, 2025, to secure an additional 135 MW of data center infrastructure at the Lake Mariner Facility.
As of December 31, 2024, TeraWulf’s mining operations were powered by predominantly zero-carbon energy, underscoring its commitment to sustainability. The company's energy sourcing methodology is based on electricity production data from the New York Independent System Operator (NYISO), specifically covering NYISO Zones A-E, where the Lake Mariner Facility is located. This approach aligns with the recommended geographic resolution for projected emissions factors for upstate New York, as published by the New York State Energy Research and Development Authority.
Lake Mariner Facility
As of December 31, 2024, the Lake Mariner Facility operated approximately 195 MW of bitcoin mining capacity at the site. The company has an agreement in place with the Power Authority of the State of New York (NYPA) for 90 MW of high-load factor power to support its bitcoin mining operations (the PPA). The PPA was executed on February 12, 2022, and has a term of ten years from the date of commencement of NYPA’s power delivery. The Lake Mariner Facility is situated on an expansive site on the shores of Lake Ontario and has the ability to scale up to 500 MW of capacity in the near term and up to 750 MW with certain transmission upgrades.
Nautilus Cryptomine Facility Sale
On October 2, 2024, the company sold its entire 25% equity interest in Nautilus Cryptomine LLC (Nautilus) to a subsidiary of Talen Energy Corporation.
Mining Equipment
The company owns specialized mining computers configured for the purpose of validating transactions on the bitcoin network. Substantially all of the miners it owns were manufactured by Bitmain and incorporate application-specific integrated circuit (ASIC) chips specialized to solve blocks on the bitcoin blockchain in return for bitcoin digital asset rewards. As of December 31, 2024, the company had deployed approximately 62,000 bitcoin miners at the Lake Mariner Facility, which represented 9.7 EH/s of self-mining capacity.
