Nebius's deal with Microsoft points to astounding growth — and CoreWeave could benefit too

Microsoft has secured a significant $17.4 billion deal with Nebius for AI-related data center services through 2031, causing Nebius stock to surge 38%. This strategic arrangement allows Microsoft to limit upfront capital expenditures and enhance financial leverage, potentially signaling a new trend for hyperscale cloud providers to manage free cash flow while meeting burgeoning AI infrastructure demands. The deal highlights the immense growth potential for AI-native cloud companies like Nebius, which commands a high valuation justified by an exceptional projected sales CAGR, and could benefit peers such as CoreWeave.

Analysis

Microsoft's new $17.4 billion contract with Nebius for data-center and AI services through 2031 validates the immense growth trajectory for specialized AI infrastructure providers. The deal structure, designed to limit Microsoft's upfront capital expenditures and preserve free cash flow, signals a potential strategic shift for hyperscalers. Notably, Microsoft was the only large AI spender among its peers—including Amazon, Alphabet, and Meta—to report positive free cash flow growth in the last two quarters. This off-balance-sheet financing model could become a trend, benefiting AI-native firms like Nebius and CoreWeave. Following the news, Nebius's stock surged 38%, pushing its forward price-to-sales ratio to a steep 18.0, a significant premium to the S&P 500 IT sector's 8.2. However, this valuation is supported by an exceptional projected two-year sales CAGR of 123.4%. Its peer, CoreWeave, appears more attractively valued with a forward P/S of 5.0 against a robust 82.0% projected sales CAGR. A key risk for both remains their lack of current profitability, with analysts forecasting net losses for Nebius through 2027 and for CoreWeave through 2026, making these pure-play growth stories dependent on future execution.

Key Decisions for Investors

• Investors should view Nebius as a high-conviction but high-risk play on the AI infrastructure build-out, where its 18.0 forward P/S ratio is predicated on executing its formidable 123.4% sales CAGR.
• Microsoft's deal structure demonstrates a capital-efficient strategy to scale AI capacity, potentially strengthening its financial position relative to competitors like Amazon and Google who face near-term free cash flow pressure from heavy capex.
• For those seeking exposure to this theme with a more favorable risk/reward profile, CoreWeave presents a relative value opportunity with its lower 5.0 forward P/S multiple against a still-elite 82.0% projected growth rate, though it shares the same unprofitability risk as Nebius.
• Monitor future contract announcements and quarterly revenue growth for both Nebius and CoreWeave, as these are the primary metrics justifying their current valuations in the absence of profitability.
