Nebius and IREN Take Opposite Paths in AI Infrastructure
Two major players are building the backbone for artificial intelligence, but their strategies diverge sharply. One relies on software scale, the other on owned energy assets.
Two companies at the forefront of artificial intelligence infrastructure recently reported earnings that highlight a stark contrast in strategy. Nebius Group and IREN are both riding the same wave of demand for computing power, yet they are executing completely different plans to meet that demand. According to reporting from GN technics/cloud (en-US), one company is building a software-heavy cloud platform from scratch, while the other is converting its existing energy footprint into GPU factories.
The difference in their approaches becomes clear when looking at their recent financial results. Nebius reported a massive increase in revenue, driven by its AI cloud unit, which achieved a high adjusted EBITDA margin. In contrast, IREN saw a drop in overall revenue due to offline mining rigs and a significant non-cash impairment. However, IREN’s AI cloud revenue more than doubled sequentially, signaling a successful pivot from cryptocurrency mining to AI infrastructure.
Software Scale Meets Energy Ownership
Nebius is betting on pricing power and a full-stack software approach. Its recent capacity auction cleared at a price 15% above previous highs, indicating strong demand for its services. The company has secured a $37.5 billion backlog and is targeting a 5-gigawatt power pipeline by year-end. This strategy allows Nebius to optimize for margin and control over its software ecosystem.
IREN, on the other hand, is optimizing for cost efficiency by leveraging its owned power and land. The company has a $4 billion contracted annual recurring revenue target by December 2026. Recent deals are pricing above $20 million per megawatt, with active talks nearing $25 million. This approach relies on the scarcity of energized land, a critical resource in the AI industry, to maintain competitive pricing for its customers.
Execution Risks Shape Future Growth
Both companies face significant execution risks that could impact their future growth. For Nebius, the challenge is converting its large customer commitments into asset-backed financing without relying heavily on equity sales. The company has already sold a substantial number of shares, which raises questions about its capital strategy. Investors will be watching closely to see if Nebius can sustain its growth without diluting shareholder value.
IREN’s main risk lies in construction delays. A significant portion of its December-quarter capacity comes online late, which could disrupt its revenue timeline. The company must deliver its Horizons 2 through 4 projects to Microsoft on schedule to meet its targets. Any slip in construction or GPU supply could affect its ability to capitalize on the current demand for AI infrastructure.
Valuation Reflects Divergent Strategies
The market is currently favoring Nebius due to its strong financial metrics and high margins. The stock has seen a significant run over the past six months, reflecting investor confidence in its scale-out strategy. However, the stock is not cheap, so valuation discipline is crucial. Investors need to consider whether the current price adequately accounts for the risks associated with its financing needs.
IREN appeals to investors looking for a turnaround story. Its recent gain over six months suggests potential for further growth if it can successfully execute its construction plans. The company’s focus on owned energy assets provides a unique advantage in a market where power is a bottleneck. For those comfortable with construction risk, IREN offers a different kind of exposure to the AI infrastructure boom.
