TeraWulf’s stock rises sharply after the company signs a long-term AI infrastructure lease with Anthropic valued at about $19 billion, according to multiple reports. The agreement is described as a 20-year hosting deal to provide AI data-center capacity at a Kentucky campus. Several outlets frame the announcement as part of TeraWulf’s shift away from operating purely as a bitcoin miner toward supplying infrastructure for the AI buildout.

CoinDesk and MarketWatch report that TeraWulf positions the deal as support for its business transformation, with the CEO saying the arrangement “validates” the company’s pivot toward AI-related services. CoinDesk also highlights the company’s statement that not all power capacity is equivalent in the AI race, emphasizing differences in how energy and related resources are utilized.

Cointelegraph additionally reports that TeraWulf sells its majority stake in a separate AI data-center joint venture alongside the lease announcement. Across the articles, the common points are the size of the lease, its multi-year term, the Kentucky location, and the market reaction to the company’s AI-focused strategy.
