A twenty-year, nineteen-billion-dollar lease with Anthropic anchors TeraWulf's move from bitcoin mining into AI infrastructure. This article looks at what's changed since the deal was signed.
TeraWulf ran bitcoin mining rigs in Kentucky for years, collecting block rewards while the broader crypto market swung through rallies and pullbacks. Part of that same site is turning into a data center campus built for Anthropic's AI workloads, backed by a twenty-year lease worth billions. Market conditions around the deal have changed a lot since it was first announced, with bitcoin's price climbing back above $70,000 and regulators in Washington introducing crypto rules that didn't exist a few months ago.
Bitcoin's Price Action Looks Different Than It Did in July
Bitcoin traded above $70,000 for the first time since early June during the week of August 17, according to Bloomberg, after moving in a tight range near $63,000 through most of July. That's a sharp move for six weeks of otherwise flat trading. Checking the bitcoin price on Binance confirms it held above that level into the following week, and the gains kept building from there. BTC was trading near $78,000 as of August 26, pushing Bitcoin's total market cap to roughly $1.57 trillion, though it was down slightly on the day and still sits well below the $126,198 all-time high set in October of last year.
Two developments coincided with the move. Analysts watched as crypto shares began to climb just a day after the U.S. Treasury Department said it would support more ?long-duration bonds. Treasury officials doubled long-term bond buybacks, pushing yields lower, and President Trump encouraged Congress to pass the Clarity Act, a bill that would define whether cryptocurrencies count as securities or commodities. Lower yields tend to push investors toward riskier assets, and that pattern held here as well. Short positions worth close to $3 billion were forced to close within about an hour.
Regulation Crypto Assets, the SEC's first crypto-specific fundraising rule, was published on August 18 and opened a sixty-day public comment period. Congress still has to act on the Clarity Act itself, which faces a difficult path in the Senate: a cloture vote scheduled for mid-September needs about six more Democratic votes than it has right now.
TeraWulf's Second-Quarter Results Show How Much the Business Changed
TeraWulf filed second-quarter results on August 5, and the numbers show a business that looks little like the one mining bitcoin a year earlier. Filings confirmed the lease with Anthropic at the Justified Data campus in Kentucky and added the Muskie Data Campus, a separate site in the eastern part of the state with room for gigawatt-scale expansion. TeraWulf also brought a third building online at its Lake Mariner site in New York, pushing revenue-generating capacity there to 102 megawatts and triggering $600 million in credit support that Google provides for a separate lease with Fluidstack.
Chairman and CEO Paul Prager described the quarter as one focused on execution, and the balance sheet moves back him up. Selling the company's 50.1% stake in the Abernathy Joint Venture, a Texas data center project, for about $530 million let TeraWulf put that capital into sites it controls outright instead of through a partnership (TeraWulf had originally invested $450 million in Abernathy, so the sale came at a premium). GAAP net income showed a loss of $939.9 million for the quarter, though most of that came from a non-cash accounting swing tied to the value of warrants held by Google, not from operations.
Revenue from the HPC leasing segment climbed 52% from the prior quarter. Its reported profit margin sat at 28%, which management attributes largely to costs tied to sites still under construction. Strip those out, executives say, and the margin moves closer to 80%, which is the long-term target the company has set for that business.
The Debt Behind the Kentucky Build
Justified Data, the Kentucky campus TeraWulf is building for Anthropic, still needs construction to catch up with the lease terms. First power delivery is scheduled for the second half of 2027, with full capacity expected by early 2028, according to reporting on the deal.
Another interesting facet to dig into is how TeraWulf is paying for that build. TeraWulf is raising $3.5 billion through loans and high-yield bonds, layered on top of two earlier bond sales completed within the last year. Bitcoin miners haven't typically had access to financing structured this way, since lenders have historically priced mining companies as commodity businesses tied to a volatile coin price rather than as landlords holding signed, long-term leases.
Breaking down that financing:
- $3.5 billion raised through new loans and high-yield bonds
- $1.3 billion bond sale completed in December 2025
- $3.2 billion bond sale completed in October 2025
- $19 billion in contracted revenue from the Anthropic lease over 20 years
- Muskie Data Campus acquisition, adding gigawatt-scale capacity in Kentucky
Management flagged some risk alongside the numbers. Labor shortages among licensed electricians and changing design expectations from large tenants both came up on the Q2 call, according to a summary from Seeking Alpha, and the company says it's adjusting its development schedule to account for both.
Wall Street's Reaction Across the Sector
IREN, Hut 8, and Cipher Mining have made similar moves this year, signing multi-year AI hosting contracts instead of relying only on bitcoin mining revenue, and their stock prices have responded. Morgan Stanley raised its TeraWulf price target from $66.50 to $72 within a day of the Anthropic lease announcement and kept its Overweight rating (a fast turnaround for an analyst note, even by Wall Street standards).
Anyone following the equity side of digital assets already knows that category covers miners, exchanges, blockchain firms, payment processors, and infrastructure companies. TeraWulf's move makes the case for looking past bitcoin's daily price and toward things like contract length and the credit quality of the counterparty.
Bitcoin's climb past $70,000 doesn't change that math on its own. It adds another data point to a trend that started before this particular rally: companies with signed, long-term contracts are getting valued differently than companies still exposed to bitcoin's price swings.
Kentucky's campus began as a bitcoin mining site and functions today more like a utility business, with contracts that run for decades instead of one quarter at a time.
