Nebius Group, the AI-focused cloud infrastructure company trading on Nasdaq, posted a 514% increase in second-quarter cloud sales, powered by demand for GPU computing resources across the AI industry.

The number is eye-catching on its own, but it’s actually a deceleration from the company’s Q1 2026 performance, where AI cloud revenue hit $389.7 million for an 841% year-over-year increase.

A revenue engine built almost entirely on AI

In Q1 2026, the company pulled in $399 million in total revenue, a 684% jump compared to the prior year. Of that, $389.7 million came from AI cloud services — roughly 98% of total revenue flowing from a single business line.

For the full year 2026, Nebius is guiding for revenues between $3B and $3.4B with an approximately 40% adjusted EBITDA margin. The company is also targeting an annualized run-rate revenue of $7B to $9B.
