Global data centre investment set to soar to $3T

Global data centre investment set to soar to $3T is a public record based on article evidence, entity context, event links, and relationship context.

Moody’s Ratings forecasts at least $3 trillion in global data-centre investment over the next five years to support explosive AI and cloud computing demand, with major hyperscalers leading the way. The financing mix will diversify beyond traditional bank loans, and energy and regulatory constraints could shape where new capacity is built.

What happened: Moody’s signals historic data centre funding surge Moody’s Ratings has released a detailed outlook suggesting that global spending on data centres will reach a minimum of $3 trillion over the next five years to meet burgeoning demand for artificial intelligence (AI), cloud computing and digital services. This investment will span construction of facilities, acquisition of servers and networking gear, expansion of electrical and cooling infrastructure, and financing costs associated with both emerging and established markets.

The largest technology firms including Microsoft, Amazon, Alphabet, Oracle, Meta and the AI infrastructure specialist CoreWeave collectively deployed nearly $400 billion in data-centre capital expenditure in 2025 and are projected to increase that to about $500 billion in 2026. These hyperscalers’ commitments form the core of the demand driving Moody’s projection. Moody’s analysis also highlights changes in how projects are financed.

With capital requirements so large, institutional investors and alternative debt products such as commercial mortgage-backed securities are expected to play a bigger role, helping to fund facilities that banks might traditionally avoid.

Hyperscale facilities not only underpin AI training and inference but also host vast amounts of cloud data, internet traffic and enterprise workloads. Their expansion is central to national competitiveness, digital transformation and new technology rollouts. However, rapid investment raises several challenges. Power availability and grid capacity are key bottlenecks in many regions, potentially limiting where new centres can be built. Regulatory and local planning hurdles often tied to environmental and energy concerns could also slow development or shift it to more receptive jurisdictions.

This investment wave may also reshape financial markets. The diversification of financing channels suggests that data-centre expansion will influence credit markets, bond issuance and institutional investment strategies connecting technology infrastructure with broader financial trends.
