Nebius is starting to look like an emerging AI hyperscaler with a credible way to fund its buildout. Q2 revenue was $582M, ARR reached $3B and the core AI business earned a 50% adjusted EBITDA margin; capacity is sold out, pricing is rising, and management thinks all 2027 capacity could be sold today. Four new contracts averaging over $1B pay about $20-25M per MW, with prepayments covering 50-60% of related capex. The open question is whether it can stop relying on repeated equity raises. x.comÂ
