IREN has power for a 300 MW Spain AI data center, but no tenant

WIRE · NEOCLOUDS · IREN · Data as at 25 Oct 2026

IREN now has the power for a big European AI data center, but not the customer. On 21 October 2026, at Nvidia's GTC Berlin conference, the AI cloud company said it has secured grid-connected power and a civil works licence for a planned campus of about 300 MW in Badajoz, Spain, with first operations targeted for 2028. It also set up IREN Europe, chaired by former Banco Santander chief executive Ángel Corcóstegui. The release named no customer and no construction budget, and Europa Press reported that the building permit is still pending. On the neoclouds layer, Badajoz is a powered plot waiting for a tenant, in the same month that neocloud credit got expensive.

What happened

Why cash cares

For a neocloud, the price of money depends on who signed the contract. IREN's own book shows it. In its full-year results on 27 August, it said the GPUs for its Microsoft contract are financed at an average of 6.0%, which together with Microsoft's prepayments covers 96% of the GPU bill. For its Mackenzie expansion, serving customers without investment-grade ratings, a $2.4 billion loan led by Blue Owl and PIMCO costs 9.0% fixed and covers 90% of the GPU bill. The better the tenant's credit, the cheaper and larger the loan.

Badajoz has no tenant yet, so it has no price for its debt. IREN says it is well funded today, with about $14 billion of cash, committed GPU financing and customer prepayments as of the August results. But that money is tied to capacity it has already sold. The company's own wording for 2028 capacity, which is when Badajoz is due, is that "customer and financing discussions" are "progressing in parallel".

The pricing IREN is seeing is strong. It says recent three-year contracts bring in more than $20 million of revenue per megawatt of IT load, with customer prepayments covering 45% to 55% of GPU spending. If Badajoz signs on those terms, the debt question gets much easier. If it signs later, or with a weaker customer, it borrows closer to where the neocloud market priced this month.

Figure: the tenant sets the interest rate, and Badajoz does not have one yet. Financing rates from IREN's 27 August 2026 results; CoreWeave yield as reported by CNBC on 21 October 2026; site status from IREN and Europa Press, 21 October 2026.

The second-order read

Who gets paid. The site preparation contractors first, now that the civil works licence lets IREN level the land and lay foundations on a plot it owns. Nvidia is the long-dated winner if the campus fills, since IREN designed it around Nvidia's platform. A future tenant also gains: a powered European site with a 2028 date gives it a bargaining position on price.

Who waits. Builders of the halls, makers of the liquid cooling and electrical gear, and IREN shareholders. Orders for the building itself follow the building permit, and the GPUs follow a customer. Neither has been announced.

Who pays more. IREN, if the tenant arrives late. A plot with power is worth a lot, but it earns nothing until a contract lets IREN borrow against it. CNBC reported that CoreWeave's default swap spread alone widened 39% in October.

Stuck step. A signed customer for Badajoz. Power is done, the land is done, and the pricing on recent contracts is good. The step that turns this site into cheap GPU debt is a name on a contract. We traced the same pressure when CoreWeave's default swaps went above 1,000 basis points, and in what IREN does.

Two cautions

The 300 MW is planned capacity, not the IT load that IREN prices its contracts on, so the revenue a full campus could earn cannot be read off the headline number.

Being early is the point of IREN's model: it secures power and land first and signs customers after, and it says its 2026 capacity is now largely sold. A missing customer more than a year before construction is even fully permitted is normal, not a red flag on its own.

What would change the view

• A named customer for Badajoz with a prepayment, which would show European demand for regional AI cloud capacity and set the financing cost.
• The building permit, and a construction budget, which would turn the plot into orders for builders and equipment makers.
• Neocloud credit easing, which would lower the price of debt for every unsigned site, not only this one.

What to watch

• IREN's next quarterly results, for any update on 2028 customers, Badajoz spending and the $4 billion annualised revenue target for 31 December.
• CoreWeave's and Nebius's next quarterly results, for the cost of new neocloud debt.
• Spanish permits for the Badajoz buildings, which Europa Press says are still pending.
