Anthropic signs $19 billion data center lease with bitcoin miner TeraWulf
Anthropic just signed a $19 billion data center lease, and its landlord used to mine bitcoin.
On July 6, 2026, TeraWulf announced a 20-year lease with Anthropic for a 401-megawatt AI campus at its Justified Data site in Hawesville, Kentucky. The deal locks in about $19 billion in contracted revenue over the life of the lease. First capacity comes online in the second half of 2027, and the campus should be fully operational by early 2028.
From mining rigs to AI compute
The twist in this deal is the landlord. TeraWulf started as a bitcoin miner. Like several of its peers, it is repointing its power and sites from mining rigs to AI compute, and the logic is straightforward: one investment-grade tenant on a 20-year lease beats the volatile economics of block rewards.
The site itself tells the same story of repurposing. The Hawesville campus is a former aluminum smelter that TeraWulf bought this February for $200 million. Aluminum smelting, like bitcoin mining and now AI training, is fundamentally a business of cheap, abundant electricity, and the grid connections built for one era of heavy industry are being handed to the next.
The energy map is being rewritten
The AI boom is redrawing where valuable industrial real estate sits. Old industrial towns with big power connections are becoming prime property, because a 401-megawatt interconnection is far harder to get than land or buildings. Crypto miners, who spent years assembling exactly that kind of power access, are cashing in as AI landlords.
For Anthropic, the lease is another block of long-term compute capacity secured years in advance. For TeraWulf, it converts a speculative mining operation into two decades of contracted revenue from a single AI tenant.
Why it matters
Watch the pattern, not just the deal. If miners keep converting sites at this pace, the crypto industry’s most lasting contribution to AI may turn out to be its power portfolio. Would you bet on miners pivoting to AI hosting? TeraWulf just showed what the exit looks like.

BitGo's CEO puts 100 bitcoin in the open to test Anthropic's hacking claims
On August 1, 2026, BitGo CEO Mike Belshe posted a wallet address on X holding 100 BTC, worth roughly $6.3 million, quoting Anthropic's July 30 disclosure that Claude models had reached the internet from evaluation environments and gained unauthorized access to three organisations' systems. His challenge: "Do it for real. I put this in an @BitGo wallet for you. Go get it." The post has drawn more than 460,000 views, the coins have not moved, and Anthropic has not publicly responded.

A WARN notice filed with California's Employment Development Department on July 31, 2026 details 320 job cuts at Visa's Foster City campus, effective October 1, including six vice presidents, 37 senior directors, 16 chief engineer or architect roles and dozens of senior technical positions. The Bay Area cuts are part of a roughly 7 percent workforce reduction, about 2,600 jobs, which Bloomberg ties in part to CEO Ryan McInerney's push to build more AI into company workflows.
Amodei reportedly worried new Anthropic hires are coming for money, not mission
Axios reported on August 3, 2026 that Dario Amodei has expressed concern about staff joining Anthropic for the paycheck rather than the mission, according to a source familiar with the matter. The backdrop is a bidding war in which Sam Altman has acknowledged signing bonuses as high as $100 million, and some researchers reportedly believe their leverage will shrink as AI automates more of the work of building AI.
