Markets Bitcoin miner TeraWulf soars on a $19 billion AI data-center lease with Anthropic The onetime pure bitcoin miner signed a 20-year deal to host the AI firm at a Kentucky campus, the latest crypto-adjacent company to trade mining for the steadier money in artificial-intelligence infrastructure.

The Anthropic deal is expected to generate roughly $19 billion in contracted revenue over its initial term, exceeding TeraWulf’s roughly $12 billion market value and underscoring how AI hosting is reshaping the economics of former crypto miners. TeraWulf will sell its 50.1% stake in a Texas data-center joint venture for about $530 million as part of a broader industry shift, with bitcoin miners unloading coins and infrastructure to pursue steadier AI-computing contracts even as bitcoin prices soften. TeraWulf, a bitcoin miner that has remade itself into an AI landlord, signed a 20-year lease with Anthropic to host the AI company at a Kentucky data center, sending its shares up as much as 19% on Monday before they settled to a gain of about 4%. The lease covers TeraWulf's Justified Data campus in Hawesville, Kentucky, which will provide about 401 megawatts of computing capacity built out in phases, with the first power expected in the second half of 2027 and the full site running by early 2028, the company said. TeraWulf expects the deal to generate roughly $19 billion in contracted revenue over its initial term, backed by what it described as an investment-grade credit. That figure is larger than the entire company. TeraWulf carries a market value around $12 billion, so the lease represents more than the whole business is currently worth in future revenue - a measure of how much the AI buildout is reshaping the economics of companies that once only mined bitcoin. The stock is up more than 80% this year. TeraWulf began as a bitcoin miner, running warehouses of specialized computers to earn newly issued coins, a business whose margins tightened after last year's halving cut the mining reward in half. Like several of its peers , it has pointed its power capacity and sites at hosting AI computing instead, where a single tenant on a long lease offers steadier income than the volatile economics of mining. The company still runs a bitcoin operation, but the Anthropic lease and its wider pipeline may now define its value. Meanwhile, TeraWulf added it will sell its entire 50.1% stake in the Abernathy data-center joint venture in Texas to a group led by its partner Fluidstack for about $530 million, monetizing roughly $450 million of invested capital at a premium and freeing cash to expand data centers it owns outright. The deal fits a rotation CoinDesk has tracked all year. As of March 2026, Bitcoin miners sold more than 15,000 coins from peak holdings and signed over $70 billion in AI computing contracts, chasing the steadier margins of the AI trade, the same shift of capital toward artificial intelligence that has pulled money out of crypto through a losing first half. The lift stood out against a soft day for bitcoin itself. The token slipped toward $61,900 on Monday after Strategy disclosed the sale of 3,588 bitcoin for about $216 million, a sharp step up from the 32 coins it sold weeks ago.
