The gigawatt promises this week just turned into something you can put on a balance sheet — and today, the financing is the story. If you're just joining, Anthropic's Kentucky build started with a 20-year TeraWulf lease for up to 401 megawatts at the Justified campus in Hawesville. It's expected to generate roughly $19 billion for TeraWulf, with first capacity slated for late 2027. And it turns a former aluminum-smelter site into a focal point in the AI power race. This is the AI Daily Briefing. Today: a Bitcoin miner recycling capital around one AI lab, a London build-out stacking debt on equity, and a campus that actually lit up on schedule. Let's start in Kentucky. If Anthropic U.S. data-center leases matters to you, hit follow — we'll be back on it soon. From The News-Enterprise:
The artificial intelligence company behind the chatbot Claude signed a $19 billion, 20-year lease at a Kentucky data center campus being built in Hancock County. California-based Anthropic will be the tenant at the Justified DataPower site in Hawesville, the facility’s developer — TeraWulf Inc. — announced Monday.
So here's the local-paper version, and I kind of love it: a $19 billion lease measured in homes. 401 megawatts, enough to power at least 300,000 houses. That's the number the utility desk understands. And the Hancock County angle actually earns its place — first AI tenant publicly announced in Kentucky, at a site literally named Justified DataPower. You can't script that. The math I keep coming back to: $19 billion over 20 years is roughly $950 million a year for 401 MW. Anthropic just locked in a fixed rate through 2046. Prager's quote is telling — he calls it validation of TeraWulf's ability to source power and secure long-term commitments. Basically, a former Bitcoin miner is reintroducing itself as a landlord. Twenty years is a long time to be certain about anything in compute. If inference costs compress the way everyone swears they will, that $950 million a year looks expensive by year ten. So is it a hedge or a trap? For Anthropic? Depends whether they'd rather overpay for certainty than get squeezed out of power entirely. Right now certainty is the scarce thing, not dollars. From Mels Dees at Techzine Global:
TeraWulf has signed a 20-year agreement with AI company Anthropic to develop a 401 MW AI campus in Kentucky. At the same time, the company is selling its majority stake in another AI data center project to Fluidstack. The two transactions represent billions of dollars in future revenue and freed-up investment capital.
Okay, so the anchor-tenant question in Kentucky is settled — 401 MW, Anthropic, twenty years, Hawesville. I can let that part go. But now we've got a number to stress-test: $19 billion over twenty years is roughly $950 million a year for 401 megawatts. And that's a fixed rate. If inference compute compresses ten-x by 2035 — which it might — Anthropic just locked in a lease that looks brilliant today and expensive in year fifteen. Is that a hedge or a trap? That first piece gave us the site and the dollar figure. Techzine sharpens the other half of the same day — TeraWulf offloading its majority stake to Fluidstack. They're recycling capital in real time: lock a 20-year anchor on one asset, monetize the other to fund the build. The credit detail matters too — Techzine says the lease is backed by an investment-grade profile. That's how $19 billion in future rent becomes something a bank will finance against today.

TeraWulf (NASDAQ: WULF) said Monday it entered into a 20-year lease with Anthropic for approximately 401 MW of critical IT load at its Justified Data campus in Hawesville, Kentucky, and agreed to sell its 50.1% interest in the Abernathy joint venture to a buyer group led by Fluidstack for about $530 million.
All right, the anchor-tenant question we've been waiting on all week is done: Anthropic, 401 MW, Hawesville, Kentucky, $19 billion over 20 years. Real name, real number, real site. And back in March, that same Justified Data campus had zero megawatts contracted. This single deal doubles TeraWulf's entire contracted load. But here's what nobody's putting next to the $19 billion: the $530 million Abernathy stake they're selling to Fluidstack. Same day, same filing. TeraWulf is cashing out of one asset to help fund the one with Anthropic attached. That's the move I'd isolate. A former Bitcoin miner is recycling capital around a single AI lab — locking a 20-year anchor on one site, then monetizing the other to pay for the build. Now do the math forward. $19B over 20 years is roughly $950 million a year for 401 MW. Anthropic just fixed that rate through 2047. If inference compute compresses 10x by 2035, that lease looks a lot less clever in year fifteen. Same question, then: hedge or trap? Depends who eats the cost curve. Fixed lease means the utilization risk sits on the tenant, not the landlord. Anthropic's betting demand outruns deflation. That's a real bet, not a footnote. From Ana-Maria Stanciuc at The Next Web:
Nscale has closed a $900m revolving credit facility, a standing pool of borrowing it will draw on to speed up its data-centre build-out across the US, Europe, and Asia-Pacific, the company said on Tuesday. The London firm, which raised $2bn in a Series C at a $14.6bn valuation in March, is now stacking debt almost as quickly as it has raised equity.
So after the TeraWulf piece we just hit — tenant, site, and a $19B number I can actually price — here's Nscale doing the opposite. $900M revolving facility, syndicated across a dozen banks, and I don't see a single anchor tenant in the story. Right, but the structure is what's new here. Most of the financing we've been talking about is one-off — equity rounds, vendor financing, long-term leases. A revolver is a standing draw mechanism. That's a different bet on how fast they can deploy. And look at who signed up. J.P. Morgan, Goldman, Morgan Stanley, MUFG — twelve banks — for a company founded two years ago. That's a syndicate you'd build for an established borrower, not a startup that's done three rounds in eighteen months. The $14.6B valuation from March plus a $900M debt layer on top — that's institutional lenders walking into the buildout as a new kind of capital: banks, rather than telcos or hyperscalers. And that's fine — a revolver doesn't dilute shareholders, and after they had to raise $790M project by project for the Narvik site, I get why they want a standing pool. But the demand side is still blank. This one's from CNW:
Greenfield development is underway on the 260 MW of critical IT Phase II build, with civil and structural work advancing and Phase II data hall deliveries expected to commence in the first half of 2027.
All week we've been swimming in intent — Korean gigawatt targets, Kentucky leases where the ink's still drying. Helios gives us an actual handoff: Galaxy delivered 133 megawatts of critical IT load to CoreWeave, on schedule, and rent started in Q2. And that's the word that matters — delivered. Past the commitment, past the contract. The power is flowing, and there's a paying tenant on the other end. It's a fifteen-year lease, and the site flipped from construction to revenue-generating in a matter of months. Across all three phases, CoreWeave's committed to 526 megawatts. But Phase I is the part that's actually humming right now. After the TeraWulf-Anthropic piece we just hit — a twenty-year lease that doesn't turn on until 2027 — it's clarifying to see a building that's already lit up. One of these you can walk into today. Right. Everything else this week is a promise with a date attached. Helios is the bar those promises get measured against — 200 megawatts gross, on the schedule they gave, with no slip. Phase II's the tell for me, though. 260 megawatts of greenfield, civil and structural already moving, deliveries slated for the first half of 2027. If they hit that on schedule too, Galaxy's got a repeatable playbook.

What we’re watching next: TeraWulf says the leased Justified Data capacity is slated to start coming online in the second half of 2027, with full build-out expected in early 2028. Galaxy expects Phase II data hall deliveries at Helios to begin in the first half of 2027.
