Nebius Group will enter the Nasdaq-100 Index on June 22 as part of the index’s quarterly rebalance, bringing the Amsterdam-based AI cloud company into one of the world’s most closely tracked equity benchmarks after a dramatic run-up in its stock price.

The company reported a 684 percent revenue increase in the first quarter of 2026, fuelled by a series of major contracts and a growing footprint in AI data infrastructure. Shares have risen more than 480 percent over the past year, with the stock nearing the 300 dollar mark in premarket trading on Friday ahead of the official inclusion.

Nebius reached a second major agreement with Meta Platforms in March 2026, a deal valued at up to 27 billion dollars over five years for AI computing capacity. NVIDIA has also made a 2 billion dollar equity investment in the company, deepening a relationship that spans both hardware supply and strategic alignment in the global AI build-out.

The company raised its 2026 capital expenditure guidance to between 20 billion and 25 billion dollars, up from a prior range of 16 billion to 20 billion. Nebius also holds a 1.7 billion pound UK capacity expansion plan as it works to establish itself as a leading independent AI cloud provider in Europe and North America.

Index-tracking funds tied to the Nasdaq-100 are required to adjust their portfolios to include Nebius shares from June 22, a mechanical buying pressure that has already attracted significant institutional attention in the days leading up to the rebalance.

Nebius operates large-scale GPU clusters for AI training and inference workloads, competing with hyperscalers like Microsoft’s Japan AI investment and Amazon’s cloud expansion. The company was previously a subsidiary of Russian internet group Yandex before restructuring and relisting in 2024 under its current name.

The OpenAI IPO process is running in parallel, with the company now targeting a valuation above one trillion dollars. Nebius’s Nasdaq-100 inclusion reflects a broader market appetite for AI infrastructure exposure that extends well beyond the handful of US hyperscalers that have traditionally dominated the sector. Whether the company can sustain its revenue trajectory as competition intensifies will be the central question for investors adjusting positions this week.
