A Bitcoin miner just signed a $19B AI deal — why miners are becoming AI landlords

TeraWulf, a company that started out as a Bitcoin miner, has signed a 20-year deal to rent out a data center to Anthropic, an artificial-intelligence company. The lease is expected to bring in about $19 billion over its term — more than the entire company is currently worth — and its stock jumped on the news.

Under the agreement, Anthropic will use a purpose-built campus in Hawesville, Kentucky, capable of supplying about 401 megawatts of computing power, with the first phase due in late 2027. TeraWulf also agreed to sell its majority stake in a separate Texas data-center project for around $530 million, freeing up cash to build more sites it owns outright.

To see why this matters, it helps to know what Bitcoin mining is. Miners run warehouses full of specialized computers that compete to add new blocks to the Bitcoin network, earning newly issued coins as a reward. After last year's 'halving' cut that reward in half, those margins got thinner and more volatile.

Those same warehouses have something AI companies desperately want: sites with lots of electricity, cooling and grid connections. So several miners — TeraWulf among them, along with names like IREN, Hut 8 and Cipher — are leasing their power and space to AI firms, trading the ups and downs of mining for the steadier income of a long-term tenant. Earlier this year, miners had already signed over $70 billion in AI computing contracts.

For beginners, there is a subtle takeaway. A 'Bitcoin miner' is increasingly not a pure bet on Bitcoin — some of these companies now earn more from renting out AI computing than from mining coins. This is information, not advice, but it is a reminder to look at what a company actually does before assuming its stock moves in step with Bitcoin's price.
