hyperscaler capex
The capital expenditure that Microsoft, Google, Amazon, Meta, and Oracle are spending on AI infrastructure, totaling roughly $300B+ annually by 2025-2026 and dominating the supply-and-demand signal for the entire stack.
The annual capital spending the largest cloud providers commit to AI infrastructure, primarily data center construction, GPUsiliconA massively parallel processor originally designed for graphics, repurposed since the 2010s as the dominant compute substrate for both training and inference of large neural networks. Open full entry procurement, networking, and power agreements. As of 2025 calendar guidance, Microsoft is at ~$80B, Alphabet at ~$75B, Meta at $60-65B, Amazon above $100B (AWS-attributable share large but not separately disclosed), and Oracle stepping into the same range via Stargate.
The combined number is the single biggest input signal for the rest of the open AI stack: how many chips ship, where they ship, what power gets contracted, what models get trained at frontierweightsThe current capability envelope of AI, defined by the most capable models in deployment at any given time; an evolving label rather than a fixed threshold. Open full entry scale. When Microsoft commits an additional $20B to AI infrastructure in a quarter, that ripples through NVIDIA orders, neocloudinfrastructureA specialized cloud provider focused exclusively on GPU and AI workloads, operating outside the traditional AWS/Azure/GCP hyperscaler perimeter, with CoreWeave, Lambda, and Voltage Park as the canonical examples. Open full entry allocations, nuclear PPAinfrastructureA long-term contract under which an AI operator commits to buy a defined nuclear-generated power output, becoming the cornerstone financing mechanism for gigawatt-class AI buildouts. Open full entry pricing, and grid interconnect queues.
For sovereignty-aligned readers the relevant question is whether this concentration produces a stable single-region monopoly, a multi-pole oligopoly, or an opening for non-hyperscaler operators (sovereign-state programs, neoclouds, decentralized markets) to remain competitive at meaningful scale.
