AI Expansion and Its Impact on Data Centers

The technological landscape is shifting rapidly, and at the center of this transformation is artificial intelligence (AI). A recent report from Dell'Oro Group highlights an unprecedented surge in data center capital expenditures (capex), with projections reaching a staggering $1.7 trillion globally by 2030, primarily fueled by AI advancements.

The Rise of Hyperscalers and Neo Clouds

According to the report, hyperscale and neo cloud providers, along with sovereign AI projects, are stepping into a new era of infrastructure development. The top four US hyperscale cloud service providers—Amazon, Google, Meta, and Microsoft—demonstrated considerable growth, collectively amassing nearly $600 billion in data center capex by the beginning of 2026. This signifies an aggressive move as these companies continue to invest significantly in AI-related infrastructure despite scrutiny over potential returns from their investments.

Baron Fung, Senior Research Director at Dell'Oro Group, noted that these hyperscalers are backed by substantial cash reserves and maintain a long-term outlook focused on acquiring market share. This influx of investment is being significantly driven by the deployment of larger, more intricate AI clusters, resulting in increased demands for high-performance networking, storage solutions, inference capacity, and sophisticated power and cooling systems.

Global Data Center Capex Dynamics

The trend is not limited to the top four hyperscalers. Emerging AI model developers and neo cloud service providers are also fast-tracking their data center expansions. With global data center capital expenditures anticipated to approach $1 trillion by 2026, the sector is poised to reach this major milestone earlier than expected. The report indicates that accelerated servers for AI training and specific workloads may account for about two-thirds of all spending in data center infrastructure by the end of the decade.

While the leadership in capex will still be held by the top US hyperscalers—expected to contribute roughly half of the global figure by 2030—there’s a notable rise in investment from new AI model builders and neo cloud providers, which is expected to continue at substantial growth rates.

However, not all sectors are experiencing the same expansion. Outside the hyperscale segment, enterprise data center investments are constrained by various factors including tariffs, monetary policies, and uncertainties regarding ROI from AI ventures.
