Much of the bitcoin mining industry has expanded into AI infrastructure over the past couple of years, and now one miner’s AI pivot is paying off massively via an Anthropic deal involving datacenter capacity coming online by 2028 and potentially generating $19 billion in revenue. The move was announced by datacenter infrastructure provider TeraWulf on Monday and involves a 20-year lease by Anthropic for a new infrastructure campus in Hawesville, Kentucky. Specifically, the agreement covers about 401 megawatts of critical IT load at TeraWulf’s Justified Data campus, a purpose-built AI facility expected to begin operating during the second half of 2027 and reach full capacity in early 2028. The projected $19 billion represents contracted revenue over the initial 20-year term, rather than money TeraWulf will receive upfront. The company also agreed to sell its 50.1% stake in the 168-megawatt Abernathy data center joint venture in Texas to an investor group led by Fluidstack. TeraWulf said it is selling the stake at a premium to its roughly $450 million investment, although it did not disclose the transaction’s purchase price. Following the Anthropic agreement, TeraWulf says its portfolio includes 839 megawatts of leased critical IT capacity.
