Oracle ramps up AI-ready data centre investments with 431% CapEx surge

The rapid adoption of generative AI has triggered an unprecedented escalation in hyperscaler infrastructure spending. To analyse these trends, BestBrokers compiled and standardised AI-related revenue or the closest disclosed segment data from StockAnalysis across 20 publicly listed companies operating within the global AI supply chain. The data shows how monetisation is distributed across the ecosystem and which segments have captured the strongest growth between 2022 and 2025.

The data shows that hyperscaler capital spending has surged from approximately $158 billion in 2022 to more than $411 billion in 2025, reflecting a 160% increase in just three years as the AI infrastructure race intensifies. Amazon remains the largest spender overall, increasing annual CapEx from $63.6B to $131.8B, while Alphabet nearly tripled infrastructure investment during the same period, rising from $31.5B to $91.5B. Microsoft also more than tripled annual spending, climbing from $24.8B to $83.1B as it accelerated enterprise AI and cloud infrastructure expansion.

Oracle emerged as the fastest-growing hyperscaler by infrastructure investment intensity. Its annual capital expenditures increased 431% between 2022 and 2025, rising from $6.7 billion to $35.5 billion, significantly outpacing every other company in the dataset. The scale of this increase reflects Oracle’s aggressive push into AI-focused cloud infrastructure and high-density data center expansion as competition for AI workloads intensifies.

Hyperscalers with the largest CapEx growth (2022–2025):

• Oracle: +431% (from $6.68B to $35.47B)
• Microsoft: +236% (from $24.76B to $83.10B)
• Alphabet: +190% (from $31.49B to $91.45B)
• Meta: +123% (from $31.19B to $69.69B)
• ·Amazon: +107% (from $63.64B to $131.81B)

Oracle recorded the highest infrastructure investment growth in the dataset, with capital expenditures reaching 58.1% of total revenue in 2025. The company’s CapEx increased from $6.68B in 2022 to $35.47B in 2025, reflecting a 431% rise in spending as it aggressively expanded AI-ready cloud infrastructure capacity. Compared to larger hyperscalers with more diversified revenue streams, Oracle has made a concentrated strategic push toward AI cloud positioning and data center scaling.

Meta Platforms stands apart from other hyperscalers as one of the most aggressive AI infrastructure investors relative to business size, despite not selling cloud services externally. Unlike Microsoft, Amazon, Alphabet, and Oracle, whose infrastructure spending is partially offset by cloud revenue, Meta’s capital expenditure is directed entirely toward content moderation models and generative AI features across Instagram, WhatsApp, and Facebook. The company allocated 34.7% of total revenue toward capital expenditures in 2025, with annual spending rising from $31.19B in 2022 to $69.69B by 2025, second only to Oracle among hyperscalers in capital expenditure intensity relative to revenue (CapEx 34.68% of revenue versus Oracle’s 58.13%).

Microsoft substantially increased its AI deployment and hyperscale cloud expansion, with the company’s annual capital expenditures rising by 236% between 2022 and 2025. Spending rose from $24.76B to $83.10B as the company rapidly scaled Azure infrastructure and integrated AI workloads across enterprise software and cloud services. By 2025, Microsoft’s capital expenditures represented more than 27% of total revenue, highlighting the scale of investment required to maintain leadership in enterprise AI infrastructure.
