What a Bitcoin Miner Is Building for AI: The TeraWulf Story
When a Bitcoin miner announces an AI project, it is easy to imagine that it has simply swapped one set of machines for another. In TeraWulf’s case, what happens around the equipment is more interesting: who leases the capacity, who helps raise the money, and who is responsible for construction.
EDITORIAL OVERVIEW · Prepared by the project editors from the sources listed below.
The lease, financing, and construction
Back in July, TeraWulf announced a 20-year lease with Anthropic at a site in Hawesville, Kentucky. It covers approximately 401 MW of power for computing equipment. Under the terms described in the filing, rent payments begin after the relevant premises are handed over.
The November 4 news was about credit support agreements with Google for proposed debt financing and a contract with Fluor to design and build three buildings. The $19 billion cited by the company is the value of contractual lease commitments, not money already received or the amount of Google’s guarantee. The phases are expected to come online from late 2027 through the second quarter of 2028.
Two sites
Meanwhile, TeraWulf continues to mine Bitcoin at another site, Lake Mariner, although some of its infrastructure is being repurposed for high-performance computing. So a headline saying that a miner has moved into AI would describe the development less accurately than two concrete facts: mining is still operating at one site, while capacity at the other has yet to be delivered to the future tenant.
