Shares of Nebius (NBIS) are skyrocketing in Thursday's trading session, surging by an impressive 25.69% following the release of the company's robust second-quarter financial results and an upward revision of its Annual Recurring Revenue (ARR) guidance for 2025.

The cloud computing and AI infrastructure company reported a remarkable 625% year-over-year increase in Q2 revenue, reaching $105.1 million. This significant growth was primarily driven by strong demand for AI use cases, increased adoption of its services, and an expanding client base. Notably, Nebius achieved positive adjusted EBITDA in its core AI infrastructure business, signaling improved profitability in its main operations.

Investor enthusiasm was further fueled by Nebius's decision to raise its 2025 ARR guidance to a range of $900 million to $1.1 billion. This upward revision reflects management's confidence in the company's growth trajectory and its ability to capitalize on the booming AI infrastructure market. Arkady Volozh, founder and CEO of Nebius, emphasized the company's strong momentum, stating, "Demand for AI infrastructure — compute, software and services — is only going to get stronger as use cases multiply. We are aggressively scaling up capacity to capture this substantial opportunity." The company also revealed plans to secure more than 1 GW of power by the end of 2026, underlining its commitment to expansion and meeting the growing demand for AI-related services.
