Nebius looks to raise $4.5BN through bond issue

Nebius wants to borrow $4.5bn via convertible notes to keep building AI data centres and buying GPUs. It shows just how expensive the AI infrastructure race has gotten, even for firms already landing Meta and Microsoft deals.

Nebius is going back to the debt markets, and this time it's not a small ask. The Amsterdam-based AI infrastructure company said today it's looking to raise $4.5bn through convertible notes, split into two tranches: $2.75bn due in 2030 and $1.75bn maturing in 2034. The money, Nebius says, will go toward data centre construction, expanding its AI cloud offering, and buying more GPUs.
That last item is the expensive one. Nebius operates as what's often called a neocloud — it builds and runs data centres stuffed with GPUs, then rents out that compute to AI and enterprise customers who don't want to build their own infrastructure. It also layers on specialised software so those customers can actually run AI applications on top of the hardware. None of that comes cheap, and the scale of this raise says something about how much capital it takes just to stay in the game right now.
And Nebius isn't some unproven startup fishing for compute customers. It already has multi-billion-dollar contracts with Meta and Microsoft to supply them with AI infrastructure, which suggests the demand side of its business is real and sizeable. But even with those relationships locked in, the company still needs enormous amounts of upfront capital to build the physical infrastructure those contracts depend on.
The company has also been expanding beyond pure infrastructure. Back in May, Nebius acquired Eigen, a US startup that focuses on improving the performance of leading open-source AI models, in a deal worth roughly $643m in cash and stock. That acquisition, paired with this new $4.5bn raise, points to a company trying to build out both the hardware layer and the software layer of the AI stack at the same time — an expensive bet, but one that fits the broader pattern of infrastructure providers racing to lock in position before the market settles.
My take — AI-written commentary, not fact-checked reporting
Raising $4.5bn in convertible notes just to keep pace with compute demand tells you everything about where the real money in AI is going right now — not into flashy consumer apps, but into concrete, steel and GPU racks. Nebius landing Meta and Microsoft as customers is a solid vote of confidence, but it also means the neoclouds are now locked into a capital treadmill where standing still isn't an option. Expect more of these mega-raises across the sector before anyone admits the build-out might be outpacing actual revenue.
