NEW YORK, June 20, 2026, 12:05 (EDT)
- Nebius closed at $286.69 on June 18, up 2.06%, after a four-session week cut short by the Juneteenth market holiday.
- Nasdaq will add Nebius to the Nasdaq-100 before the market opens on June 22. CoreWeave joins the index the same day.
- The stock move rests on a fast-growing but capital-heavy AI cloud story: Nebius reported first-quarter revenue of $399 million, up 684% from a year earlier.
Nebius Group N.V. heads into Monday’s Nasdaq-100 debut after a sharp, holiday-shortened rally that took its Nasdaq-listed shares to $286.69 at Thursday’s close, with U.S. equity markets shut Friday for Juneteenth and then for the weekend. The stock ended the week 23.4% above its June 12 close and touched $298.80 intraday on Thursday.
Why it matters now is simple: index money. Nasdaq said the rebalance takes effect before the open on Monday, June 22; the Nasdaq-100, a benchmark of large non-financial Nasdaq-listed companies, is tracked by more than 200 investment products with over $800 billion in assets. Passive funds — funds that copy an index rather than pick stocks — will need to align with the new line-up.
That does not make Monday a one-way trade. It does put Nebius in front of a broader investor base at a time when Wall Street is still bidding up companies tied to artificial intelligence computing capacity. CoreWeave, another AI infrastructure name, enters the index in the same rebalance and will provide the closest live comparison.
Last week’s tape had a mechanical feel, but not only that. Nebius rose 11.9% on Monday, 1.9% on Tuesday, 6.0% on Wednesday and 2.1% on Thursday; volume reached 36.6 million shares on Thursday, the heaviest session in the recent table.
Nebius gave investors one fresh company marker during the week. On June 16 it said it had completed the acquisition of Eigen AI, an inference and model-optimization company; inference means running trained AI models to produce answers or decisions, while optimization means cutting the cost or time needed to do it.
The fundamental case is still the same: expand capacity fast enough to catch demand without drowning shareholders in buildout costs. Nebius reported first-quarter revenue of $399 million, up 684%, and adjusted EBITDA of $129.5 million, while purchases of property, equipment and intangible assets reached $2.47 billion. That last figure is capital expenditure, or spending on long-lived assets such as data centers and equipment.
Nvidia has helped define the story. Reuters reported in March that Nvidia agreed to invest $2 billion for a stake of about 8.3% in Nebius and that Nebius and CoreWeave are among “neocloud” companies — specialist cloud providers focused on AI customers — supplying large technology groups. Nvidia CEO Jensen Huang said then that Nebius was “building an AI cloud designed for the agentic era.” Reuters
Management has framed the expansion as a long-duration bet, not a trade. In a June 8 UK investment statement, founder and CEO Arkady Volozh said demand was “here” and Nebius was “here for the long run”; the company also said it had committed about 1.7 billion pounds to UK capacity at four sites.

The setup is less clean than the rally suggests. Monday will test how much of the move was forced index buying and how much was investors repricing the business. Index inclusion raises visibility, but it is not revenue, and a stock that has climbed more than 20% in a shortened week can invite profit-taking even when the broader AI infrastructure narrative remains intact.
But the risk is not merely a pullback. Nebius itself has flagged uncertainties around raising financing, bringing data-center capacity online on time and at acceptable cost, securing equipment and power, and competing in a market where pricing and customer demand can shift quickly. If any of those slip, the equity story turns from scarcity premium to execution risk.
The week ahead starts before the opening bell Monday. Traders will watch the first hours of Nasdaq-100 membership for liquidity and fund-flow clues; longer-term holders will be looking for signs that capacity additions, acquisitions such as Eigen AI and large cloud demand can translate into durable cash generation, not just a bigger stock chart.
