TeraWulf Inc.
TeraWulf runs large data centers powered mostly by clean energy, using them to mine bitcoin and increasingly to host artificial-intelligence computing.
TeraWulf is a power-plant-meets-computer-farm company. It builds and runs big data centers packed with specialized machines, and it sells two things from those buildings: bitcoin, which its computers "mine" around the clock, and rented computing space and power for customers who need serious number-crunching, especially artificial-intelligence and high-performance computing (HPC) workloads.
The core idea is simple. Bitcoin mining is an energy business wearing a tech costume — the machines do endless math to earn new coins, and the single biggest cost is electricity. So TeraWulf chases cheap, mostly carbon-free power, largely nuclear and hydro, and puts its facilities right next to the source. That keeps its costs low and gives it a "clean energy" story that appeals to customers and investors alike. It owns a large site in upstate New York near a nuclear plant and another in Pennsylvania. The business is now pivoting toward AI. Bitcoin mining revenue swings wildly with the coin's price, and the rewards for mining get mathematically harder over time. Renting out data-center capacity to AI and cloud customers offers longer contracts and steadier, more predictable income, so TeraWulf has been signing deals with AI-focused computing companies to host their gear. That shift is the big story for the company right now, and it is what most of the excitement — and the risk — is about.
The risks are real. Bitcoin mining is brutally cyclical, and the whole industry gets squeezed every time the network's "halving" cuts the coin reward in half, which happened most recently in 2024. TeraWulf also carries debt and must spend heavily on buildings and machines before it earns a dime, so it is a capital-hungry business that can look brilliant in a boom and painful in a bust. In short, it is a bet on cheap power plus two volatile customers — bitcoin and AI — and management is wagering that the AI side grows fast enough to smooth out the bitcoin rollercoaster.

BIG PICTURE
In Hancock County, Kentucky, 62% of residents asked said they oppose the TeraWulf data center
- 62% Oppose the data center
- 38% Do not oppose
TeraWulf's home turf is where it builds and powers its data centers, so local permission matters as much as any contract. In a survey in Hancock County, Kentucky, 62% of respondents said they oppose the planned data center there, and only 2.7% said they completely trust the company to keep its promises to the community.

Timeline
TeraWulf Is Founded
In early 2021, Paul Prager and Nazar Khan started TeraWulf with a simple idea: mine bitcoin using clean, low-cost power like nuclear, hydro and solar. Bitcoin mining eats huge amounts of electricity, so the founders bet that zero-carbon energy could make the business both greener and cheaper. That bet set the company's direction from day one.
Going Public Through Ikonics
TeraWulf needed money to build mining sites, so it merged with Ikonics, a small company already listed on Nasdaq. The deal closed at the end of 2021 and TeraWulf began trading under its own name. The listing gave it a door to public investors and the cash to grow.
Big Machine Order and Talen Deal
The company bought 30,000 bitcoin mining machines to raise its computing power. It also teamed up with power company Talen Energy in a joint venture called Nautilus Cryptomine, aiming for up to 300 megawatts of zero-carbon mining capacity. Together these moves gave TeraWulf real machines and real energy partners.
Google Backs the Pivot
As bitcoin mining became a tougher business, TeraWulf began renting out data center space for high-performance computing and AI instead. Google put in $3.2 billion of support and took a 14% stake plus warrants. That backing told the market the new direction was real, and it made Google both a big shareholder and a key credit backer.
Fluidstack Joint Venture
In October 2025 TeraWulf formed a joint venture with Fluidstack, taking a 51% share, for a 168 megawatt AI computing project at its Abernathy campus in Texas. The 25-year contract was worth about $9.5 billion in base revenue, with potential for far more. AI hosting now clearly became the main growth plan.
Muskie Data Campus in Kentucky
TeraWulf bought the Muskie Data Campus, a huge one-gigawatt site in Eastern Kentucky, with zoning already approved and long-term power secured. The first half of it was expected online in the second half of 2028, with the rest by 2030. This gave the company room to grow well beyond its current size.
Anthropic Signs 20-Year Lease
In July 2026 TeraWulf signed a 20-year lease with AI company Anthropic for about 401 megawatts at its Justified Data campus in Hawesville, Kentucky. The deal was expected to bring in roughly $19 billion over the initial term, with Google providing investment-grade credit support behind it. Long-term contracted cash flow like this was exactly what the pivot was aiming for.
Exit From the Abernathy Venture
Also in July 2026, TeraWulf sold its 50.1% stake in the Abernathy joint venture to a Fluidstack-led investor group. It got about $530 million for an investment of roughly $450 million, a solid premium. The money went back into sites it fully owned and expected to earn higher returns on, like Lake Mariner and Justified.
HPC Leasing Becomes the Main Business
By the third quarter of 2026, revenue reached $76.2 million, and HPC lease revenue nearly doubled from the quarter before to $63 million, about 83% of the total. Renting space to AI and computing customers had overtaken bitcoin mining as the company's main money maker. Management aimed for about $700 million in yearly leasing revenue by early 2027.
