Nebius Group closed a $3.5 billion senior secured financing facility with Citi, structured as a 364-day revolving commitment to accelerate AI infrastructure deployment across its global footprint. The facility targets data center construction and GPU procurement, with the short tenor suggesting either a bridge to permanent capital or an expectation of rapid asset monetization through customer contracts.
The 364-day structure is unusual at this scale. Nebius is either confident it can refinance or retire the facility within twelve months, or the arrangement includes extension options not disclosed in the initial announcement. The senior secured designation implies Citi holds a priority claim on specific assets—likely the data centers themselves and contracted revenue streams from hyperscale AI customers. This is not balance-sheet financing; this is asset-level project finance dressed as corporate credit.
Nebius split from Yandex in late 2023, taking the international cloud and AI infrastructure assets while leaving the Russian operations behind. The company has since positioned itself as a vendor-neutral AI cloud provider, competing with CoreWeave, Lambda Labs, and the hyperscaler partnerships that AWS and Google have extended to AI model builders. The $3.5 billion facility is roughly 3x the company's estimated 2023 revenue base, meaning this is growth capital with execution risk baked into the covenant package. Citi is betting on Nebius's ability to convert contracted capacity into realized billings before the facility matures.
The timing matters. Nvidia's H100 and H200 GPU supply chains have loosened in Q4 2024, and lead times for colocation and wholesale data center space have compressed from 18-24 months to 12-15 months in certain U.S. and European markets. Nebius is moving while the window is open. The facility likely includes milestones tied to capacity deployment and customer contract execution, which means any delay in data center commissioning or GPU delivery could trigger margin calls or covenant resets.
Allocators should watch for three developments in Q1 2025. First, Nebius will need to disclose utilization against the facility—how much of the $3.5 billion converts to actual capex versus sitting as availability. Second, the company's customer contract announcements will signal whether this is speculative build or contracted capacity. Third, any move to term out the facility—swapping the 364-day line for a longer-tenor bond or equity raise—would confirm this was a bridge structure from the start.
The broader read: Citi is underwriting a de-risked infrastructure play, not a technology bet. The bank holds a lien on physical assets with secondary markets for GPUs and data center shells. If Nebius stumbles, Citi owns the infrastructure and can auction it to CoreWeave, Lambda, or a hyperscaler looking to expand without construction lead time. The $3.5 billion is a hard-asset loan with a AI growth story layered on top.
The takeaway
Nebius structured $3.5B Citi facility as 364-day senior secured line—watch for contract disclosures and refinancing moves in Q1.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
