# Nebius Stock ($NBIS): The Vertically-Integrated Neocloud Scaling Into the GPU Shortage **Nebius ($NBIS) is a pure-play AI cloud that builds and operates its own NVIDIA GPU data centers and rents that compute to AI labs and enterprises.** Unlike an asset-light reseller, it owns the buildings, the racks, and the power deals. Spun out of the former Yandex group and now Nasdaq-listed (~$50B market cap), it is one of the few independent "neoclouds" with the capital, the NVIDIA relationship, and the multi-region pipeline to scale into the compute shortage rather than merely arbitrage it. ## The hardware A current-generation NVIDIA fleet on Nebius-designed racks: $NVDA H100/H200, HGX B200, GB200 Grace Blackwell, and Blackwell Ultra, with Vera Rubin capacity earmarked for future clusters. $AMD MI300X is evaluated as a secondary source to cut single-vendor risk. Host CPUs are $INTC Xeon (Sapphire/Emerald Rapids); racks come from $SMCI and Gigabyte; the silicon is fabbed by $TSM. Clusters run non-blocking NVIDIA InfiniBand with $ANET Ethernet and $JNPR routing around them, $MU memory, $PSTG all-flash storage, and $VRT plus $SBGSY power and cooling. ## The data-center footprint Operating and announced sites span **Finland** (Mäntsälä flagship ~75 MW, plus a 310 MW Lappeenranta factory), the **US** (Kansas City with Patmos, Vineland NJ 300 MW with DataOne, and a gigawatt-scale Independence, MO site), the **UK** (Ark Data Centres' Longcross Park, Surrey — an initial 4,000 Blackwell Ultra GPUs), **France** (Paris at Equinix PA10 and a 240 MW Lille factory), and **Iceland** (Keflavík, renewable). Owning the footprint is the structural difference from $CRWV-style resellers and from leasing-only peers. ## The demand side The backlog funds the capex. Anchor contracts reported in the tens of billions lead with Meta ($META) — up to ~$27B over five years (~$12B tied to NVIDIA Vera Rubin plus ~$15B flexible) — and a separate Microsoft ($MSFT) agreement reported around $17.4B. Enterprise and AI-lab customers include $SHOP, $NET, $PRX.AS, $PLTR (stack partner), Mistral, and a long tail of generative-AI startups on B200 clusters. Nebius also owns Toloka (data labeling), Avride (autonomous driving), and ~28% of ClickHouse. ## Risks - **Capex intensity** — gigawatt builds cost billions up front, funded with debt and equity; dilution and financing risk are part of the story. - **Customer concentration** — a few anchor deals carry much of the backlog. - **Competition & GPU allocation** — competes with $CRWV and the hyperscalers' own clouds; NVIDIA allocation gates growth. - **Legacy overhang** — the reported income statement still carries the old Yandex history; judge the new cloud business and the contract backlog, not the old consolidated numbers. ## How to play it $NBIS is the European-rooted, vertically-integrated neocloud in the [AI Cloud / Neoclouds] group; $CRWV is the larger US pure-play, $IREN the miner-turned-HPC operator. The names are gated by megawatts, so the trade is tied to the data-center power and nuclear build-out as much as to GPUs. *This is not financial advice — for research and education. Neocloud equities are volatile and capital-intensive.*
