Nebius stock rises around 175% after five months in 2026 as the Nvidia-backed neocloud company expands data center capacity.

Nebius has risen around 175% after five months in 2026. The company operates as a neocloud platform (AI-focused business) serving clients including Meta Platforms and Microsoft, with Nvidia as a significant investor providing early access to new technology.

Nebius is expanding rapidly: it had one data center site with 100-megawatt or greater power consumption in 2025 and is now up to seven sites. The company targets a $7 billion to $9 billion annual run rate, up from $1.25 billion at the end of 2025.

In the first quarter, revenue rose 684% year over year. Wall Street analysts project revenue will rise to $11 billion by the end of 2027, though the stock trades at 5.3 times 2027 sales with profitability a long way away.
