Nebius today announced its financial results for Q1 2026.

Key highlights:

Record ARR growth: ARR grew 674% year-over-year; full-year guidance has been updated to ARR of $7-$9 billion and revenue of $3.0-3.4 billion.

Expanded margins: Adjusted EBITDA margin in our AI cloud business nearly doubled quarter-on-quarter to 45%.

Surpassing capacity targets: Contracted capacity now exceeds 3.5 GW, surpassing our 3 GW target; we now expect to have more than 4 GW of contracted capacity by the end of 2026.

Growing our US footprint: We have secured up to 1.2 GW of power and land for a new, owned AI factory in Pennsylvania, bringing our total number of >100 MW sites to seven.

Arkady Volozh, founder and CEO, said:

“We are a technology company at our core. We have world-class engineers and deep proprietary expertise across every layer of the stack. From infrastructure and multi-tenant cloud through inference solutions and agentic platforms. We are not simply responding to where the industry stands today; we have the knowledge and experience to build the infrastructure, tools, and capabilities for where it will be tomorrow.”

300k volume at 530,am. 🚀 🚀 🚀. Should be fun!

Announced today, Nebius is licensing Clarifai’s full-stack orchestration platform for enterprise AI, along with its inference and compute orchestration technology, and welcoming core engineering and research talent from Clarifai.

This strengthens Nebius Token Factory as a full-stack inference platform following Nebius’s recent acquisition of Eigen AI. While Eigen optimizes at the model level, Clarifai’s technology optimizes the system, creating the end-to-end infrastructure required to run complex AI models reliably in production.

Clarifai founder and CEO Matthew Zeiler will join Nebius as SVP, Research, where he will lead a new team focused on frontier AI innovation across areas including multimodal reasoning, world models, token efficiency, and long-term memory.

Roman Chernin, co-founder and Chief Business Officer of Nebius, said:

“We are building a complete inference ecosystem, because delivering efficient execution at scale is a system optimization game: model optimization, system design, and compute orchestration all have to work together. The integration of Clarifai’s advanced system-building capabilities and proven team will further strengthen Nebius Token Factory, offering customers the infrastructure they need to run models reliably and cost-effectively in production.”
