Bitcoin miner TeraWulf has signed a $19 billion data-center agreement with Anthropic, and the lease includes a provision that lets Google take part of the project if the AI company fails to pay rent. The clause turns Google into an unlikely backstop for one of the largest AI infrastructure deals on record.
TeraWulf is a bitcoin miner, not an AI landlord by trade. Anthropic is the tenant.
The clause buried in the lease
The arrangement is unusual because it doesn't just tie TeraWulf to Anthropic. It ties Google to the downside. If Anthropic defaults on its rent obligations, Google can acquire a stake in the $19 billion project. That's not a standard landlord-tenant term. It reads more like a credit support agreement dressed up as a lease.
TeraWulf didn't build this deal as a pure real-estate play. The company has been converting mining capacity into AI hosting, and the Anthropic lease is the centerpiece of that pivot. The Google provision suggests the counterparties wanted a deep-pocketed fallback in place before committing capital at this scale.
Why a miner is hosting AI
Bitcoin miners have been hunting for revenue that doesn't depend on the hashprice. TeraWulf's move fits that pattern: sign a long-term lease with a creditworthy AI tenant, collect rent, and let the tenant worry about compute demand. The $19 billion figure makes it one of the bigger deals of its kind, and it puts a miner on the hook for delivering data-center capacity to a company at the center of the AI buildout.
The catch is that Anthropic is still a private company with a burn rate. A $19 billion commitment is large relative to anything it has signed before, and the Google clause is the market's acknowledgment that the rent checks aren't guaranteed.
Google's role is the tell
Google isn't named as a party to the lease. It's named as the party that can step in if the tenant stops paying. That's a specific, contingent right, and it says something about how the deal was structured: someone with a balance sheet had to stand behind Anthropic's obligation.
The provision doesn't say Google will take over the project. It says Google could acquire a stake if Anthropic defaults. Those are different outcomes, and the difference matters for TeraWulf shareholders who are effectively lending their balance sheet to an AI startup.
The deal's closing mechanics and the exact trigger for the Google clause haven't been disclosed. Watch for filings or lender documents that spell out what counts as a default and how the stake would be priced. Until then, the $19 billion headline is real, but so is the escape hatch.
