Nebius (NASDAQ: NBIS) closed Monday's regular trading session at $231.09, just a stone's throw from its 52-week high of $233.73, as the market digested news that a prominent artificial intelligence fund has taken a significant stake in the company. The Amsterdam-based firm, which is emerging as a key player in the AI compute infrastructure space, saw its shares jump 9% last Thursday after the disclosure.
According to a Schedule 13G filing with U.S. regulators, Situational Awareness LP and associated investors now hold a 5.6% stake in Nebius, representing 12.41 million Class A shares. The fund, managed by Leopold Aschenbrenner and Carl Shulman, becomes the company's largest shareholder. Gil Luria, head of technology research at D.A. Davidson, commented to Reuters, "This stake indicates he sees the most leverage right now in AI clouds and, specifically, Nebius."
Impressive First-Quarter Results
Nebius reported stellar first-quarter financials that provided plenty of ammunition for the bulls. Revenue came in at $399.0 million, an eye-popping 684% increase compared to the same period last year. Net income from continuing operations reached $621.2 million, underscoring the company's ability to capitalize on the insatiable demand for AI compute capacity.
The company also disclosed capital expenditures of $2.47 billion on property, equipment, and intangible assets during the quarter, signaling an aggressive buildout strategy. CEO Arkady Volozh noted, "We typically see several customers competing for every GPU we bring online," as he justified the higher spending as a response to customer demand rather than a defensive move.
AI Factory Expansion and Capex Guidance
In May, Nebius secured up to 1.2 gigawatts of power and land for a new AI factory in Pennsylvania, which it will own outright. This is a critical development as power access has become a hard constraint for AI data center operators. The company also raised its 2026 capital expenditure outlook to between $20 billion and $25 billion, up from the previous range of $16 billion to $20 billion. This spending is earmarked for chips, servers, and data centers.
However, the increased capex also introduces execution risks. If customer demand softens, power delivery is delayed, or financing costs rise, the very expansion that currently supports the stock could become a liability. Valuation and execution remain key concerns for investors.
Market Context and Competitive Landscape
Nebius is often grouped with other "neocloud" players like CoreWeave and IREN, which focus on renting out AI hardware rather than operating large-scale consumer cloud platforms. Barron's reported that Situational Awareness also holds sizable stakes in both CoreWeave and IREN, signaling a broader bet on the AI infrastructure theme.
The stock's recent gains have been fueled by a combination of momentum, scarcity value, and the fund's endorsement. But the next test comes on June 3, when Nebius co-founder and Chief Business Officer Roman Chernin is scheduled to host a fireside chat at the BofA Securities 2026 Global Technology conference at 4:20 p.m. EDT.
What's Next for Nebius?
With the stock trading near its all-time high, the focus now shifts to whether Nebius can build on last week's ownership surprise and sustain its upward trajectory. Traders will be looking for new supply agreements, power plans, and funding data to justify further gains. The upcoming conference could provide the catalyst needed to either confirm the rally or signal a pause.
As of Monday's close, Nebius shares were at $231.09, with the 52-week high at $233.73. The market will be watching closely to see if the company can clear that hurdle and continue its ascent in the competitive AI landscape.
