TeraWulf signed a 20-year lease with Anthropic for its Justified Data campus in Hawesville, Kentucky, a deal expected to generate approximately $19 billion in contracted revenue over the initial term. The announcement sent TeraWulf shares up more than 17% on the day — a striking outcome for a company that started life as a Bitcoin miner.

The scale of the campus. Justified Data is expected to support roughly 401 megawatts of critical IT load once fully built. Initial capacity comes online in the second half of 2027, with the site reaching full capacity by early 2028. That timeline matters: this is a multi-year commitment, not a near-term revenue bump, and the $19 billion figure averages out to roughly $950 million a year across the lease term, with actual cash flows depending on phased delivery and escalation terms.
