AIB Data Centers has locked in a 50 MW deal with Nebius AI cloud, a capacity agreement that runs for 12 years. The contract is the clearest sign yet that data-center operators once built around crypto mining are retooling for AI workloads — and chasing the steadier revenue that comes with them.
Fifty megawatts is a serious chunk of power. For a colocation or mining operator, a 12-year term on that scale is the difference between merchant risk and utility-style cash flow.
The pivot from hashrate to training clusters
Mining economics are cyclical. Block rewards, difficulty, hardware depreciation and power prices all move against operators at once, and the revenue line follows. AI infrastructure is a different business. Cloud providers sign multi-year contracts, often with take-or-pay structures, and the customer — not the operator — carries the demand risk.
That's the trade AIB is making here. Nebius, which runs an AI cloud platform, needs capacity it doesn't have to build from scratch. AIB has the power and the shell. The 12-year term is the part that matters most: it's not a spot deal, and it's not a three-year bridge. It's a commitment that both sides expect to live with.
Why Nebius wants the megawatts
AI cloud providers are in a land grab for powered shells. The bottleneck isn't GPUs anymore — it's getting enough electricity and cooling into a building fast enough to serve customers. Nebius adding 50 MW through a partner is a faster route than greenfield construction, which can take years to permit and energize.
The deal also gives Nebius scale without owning the real estate. That keeps its balance sheet lighter, which matters for a company competing against hyperscalers with far deeper pockets.
What the operators get out of it
For AIB, the appeal is straightforward. Crypto mining revenue is unpredictable. A 12-year contract with an AI cloud customer converts a volatile asset into something closer to an annuity. Lenders and investors tend to reward that. It's the same logic that's pushed several mining firms toward hosting and HPC deals over the past couple of years — the hardware was always capable, the business model just needed to change.
Whether the terms are favorable for AIB is another question. Long-duration power contracts cut both ways. If AI cloud pricing stays high, the operator may have left money on the table. If it compresses, the fixed term looks smart.
What to watch
The next concrete step is energization — getting the full 50 MW actually delivered to Nebius's racks. Power interconnection queues are long in most markets, and a signed deal doesn't mean electrons are flowing. Neither company has said where the capacity sits or when the first megawatts come online. Those details will determine whether this is a headline or a real revenue driver.
