TeraWulf, a former bitcoin miner, sees its shares rise after announcing a large AI infrastructure agreement with Anthropic. Multiple outlets report that TeraWulf signs a 20-year lease, valued at $19 billion, to host Anthropic at a data-center campus in Kentucky. The transaction reflects a broader shift by some crypto-related companies toward earning steadier revenue tied to artificial-intelligence infrastructure rather than relying solely on crypto mining.

In addition to the lease, Cointelegraph reports that TeraWulf sells its majority stake in a separate AI data-center joint venture. MarketWatch characterizes the move as validating TeraWulf’s pivot toward supporting the AI buildout, citing comments from the company’s CEO. CoinDesk similarly frames the deal as part of the ongoing reorientation of crypto-adjacent firms toward AI-focused hosting and infrastructure spending.

Across sources, the core details are the scale and length of the Anthropic lease, TeraWulf’s Kentucky hosting location, and the stock reaction to the company’s expanded AI-related business activities.
