The 16-year lease at Tydal routes NVIDIA Rubin GPUs through Volta to an unnamed AI lab. JPMorgan and another top-tier bank stand behind about $1.3 billion of credit support.
Bitdeer has signed a 16-year colocation lease at its Tydal campus in Norway worth roughly $4.7 billion in contracted revenue. The tenant is Volta, an infrastructure company that emerged from stealth on the same day; Volta in turn intends to sublet the capacity to what both parties describe only as a leading AI lab. An eight-year renewal option would extend the deal to 2050 and lift the total contract value to about $8 billion.
The site itself is not new to Bitdeer. Tydal was originally scoped as a bitcoin mining campus, and the shell space now being handed to Volta had been operating on that basis. It is being reconfigured to run 121 IT megawatts of NVIDIA Rubin GPUs, with 133 gross megawatts of upstream capacity behind it. Delivery is staged in two phases, the first by December 2026 and the second by March 2027. Dell Technologies is the specified server vendor.
The financial structure is more interesting than the headline number. Lease payments average roughly $202 per kilowatt per month over the base term — a modified gross arrangement in which Volta reimburses electricity costs separately. That corresponds to about $290 million of annual revenue with a net operating income margin Bitdeer is guiding to 90 per cent. Credit support of approximately $1.3 billion has been arranged via Letters of Credit from JPMorgan and another top-tier global bank, which is what allowed Bitdeer to book the full 16 years as contracted revenue rather than an option.
Ninety per cent NOI is the kind of number that only lands on a colocation deal when the tenant has committed to reimburse the pass-through utility bill and there is no meaningful services layer beyond racks and power. Bitdeer's role in the Tydal build is closer to landlord than operator: it is providing the physical shell, the power delivery and the mechanical plant, and taking rent. The GPU capex belongs to Volta, as does the software stack and the direct relationship with the AI lab. That is a different business from bitcoin mining, and a much less capital-intensive one for Bitdeer than continuing to buy machines to hash on its own account.
The Norwegian energy backdrop is what makes the arithmetic work. Tydal sits in a region with abundant hydro capacity and among the coldest ambient temperatures in Europe for a large industrial site, giving the facility a projected power usage effectiveness of about 1.1. Bitdeer has committed to running the site on 100 per cent renewable energy, a specification that the end lab will find easier to sell as regulatory scrutiny on AI power consumption tightens.
Tydal joins a growing list of former bitcoin mining sites being repurposed as AI infrastructure. Public miners have collectively signed contracts worth more than $70 billion of AI and HPC compute commitments over the last two years. The trend has produced some genuinely large deals: TeraWulf's 20-year contract with Anthropic, signed in July, is worth $19 billion and eclipses the miner's own market capitalisation; IREN raised its AI cloud target to $4 billion earlier this month after selling out its existing capacity; Core Scientific booked a 15-year, up-to-$14 billion deal with AMD in late July. Bitdeer's Tydal contract fits comfortably into that cluster.
For BTDR shareholders, the read-through is straightforward on the revenue side and less clear on strategy. Contracted revenue over the base term averages to roughly the same annual figure regardless of bitcoin's price or hash-price dynamics, which is a substantial diversification for a company whose stated business model still leans on self-mining. What the announcement does not resolve is how Bitdeer intends to allocate future megawatts as new sites come online: as leased colocation for AI tenants, at 90 per cent NOI margins and a predictable dollar figure, or as self-mining capacity, at margins that swing with the bitcoin price and network difficulty. Every megawatt spoken for by Volta is a megawatt Bitdeer is not hashing on.
The identity of the end AI lab is the piece of the deal that has not been disclosed. Volta's stealth-launch materials described it only as a leading AI lab and neither company has confirmed a name. Given the volumes involved, 121 megawatts of Rubin capacity is enough to train frontier models, and the shortlist of plausible tenants is not long. NVIDIA's Rubin generation is only just entering broad deployment; the customers with pre-existing allocations from Jensen Huang's team, and the balance sheets to commit to eight-figure monthly lease payments through 2042, number in single digits.
