Meta signed $41 billion in AI infrastructure agreements last week—$14 billion with CoreWeave and up to $27 billion with Amsterdam-based Nebius Group over five years. The contracts guarantee computing capacity, not speculation. CoreWeave's deal alone exceeds its trailing twelve-month revenue by a factor of seven.

Both vendors now hold forward commitments that alter their credit profiles. CoreWeave, which went public in January at a $19 billion valuation, can now backstop construction debt against contracted cash flows. Nebius—spun out of Yandex in 2024—moves from regional operator to Tier-1 hyperscale supplier in a single signature. Meta did not disclose pricing per GPU-hour, but the deal structures suggest fixed-capacity reservations rather than usage-based billing. That shifts inventory risk to the vendors and locks in Meta's marginal cost of compute through 2030.

The announcements formalize what has been visible in the colocation and power markets since late 2024: hyperscalers are securing compute before chips ship. Meta's capital expenditure guidance for 2025 sits between $64 billion and $72 billion, with roughly 60% earmarked for AI infrastructure. Outsourcing $41 billion of that to third parties preserves balance-sheet flexibility and accelerates deployment timelines. CoreWeave and Nebius own the data center shells, the power contracts, and the operational overhead. Meta owns the models and the margin.

For infrastructure investors, the shift is definitional. CoreWeave's contracted backlog now justifies mezzanine lending at sub-8% yields, a rate reserved for investment-grade credits six months ago. Nebius, which operates owned data centers in Kansas City and Finland, can now raise project finance against Meta's creditworthiness rather than its own. The company disclosed it will deploy Nvidia H200 and Blackwell-architecture GPUs under the agreement, meaning chip delivery schedules are already negotiated. That removes the largest variable cost from the equation.

Operators should track two follow-on events. First, CoreWeave's debt refinancing—expected in Q2 2025—will test whether capital markets price the Meta contract as a revenue multiple or a credit enhancement. Second, Nebius must secure an additional 400 megawatts of power capacity in the next eighteen months to meet the upper bound of its Meta commitment. Land leases in Finland and Kansas have already been filed, but interconnection queues in both jurisdictions run 24-36 months. If Nebius cannot energize capacity by mid-2026, the contract's upper tranches become theoretical.

Meta now has 41 billion reasons to believe its inference costs will not spike in 2027.
