Infrastructure has traditionally been associated with roads, bridges and railways. Today, that definition is expanding. Data centers, electricity networks, battery storage and digital connectivity have become just as important to economic growth as transport assets.
A PwC infrastructure outlook published this spring highlights this shift. Rather than identifying a short-term investment cycle, the research presents a long-term view of structural change over the next 25 years. Governments, investors and private businesses are responding to rising electricity demand, artificial intelligence, urbanization and geopolitical uncertainty with infrastructure strategies that differ significantly from previous generations.
PwC forecasts cumulative global infrastructure investment will reach US$151.1 trillion between 2025 and 2050, with annual spending rising from US$4.4 trillion in 2024 to US$6.9 trillion by 2050. The figures illustrate both the scale of future investment and the changing priorities behind it.
The next infrastructure cycle is being driven by technology as much as construction
Earlier infrastructure investment focused on expanding transport networks and supporting population growth. Those priorities remain, but digital technologies are increasingly influencing where capital is directed and how projects are designed.
Artificial intelligence provides a clear example. The rapid expansion of AI workloads has accelerated demand for large-scale data centers, which require dependable electricity supplies, advanced cooling systems and resilient communications networks. Investment decisions are no longer limited to individual facilities. They increasingly account for the wider infrastructure needed to support continuous digital operations.
PwC projects annual investment in data center buildings will rise from US$113.8 billion in 2024 to US$251.8 billion by 2027. Spending on data center facilities is expected to exceed US$1.5 trillion between 2024 and 2032.
The shift reflects a broader change in how infrastructure creates value. Physical assets remain fundamental, but their contribution increasingly depends on digital capability, operational resilience and the flexibility to accommodate future technologies.
Electrification is driving similar changes. As transport, manufacturing and commercial buildings rely more heavily on electricity, demand continues to grow for modern transmission networks, substations and energy storage. Infrastructure planning is becoming less about individual projects and more about connected systems that support long-term productivity.
Power networks, transport and data centers are becoming one connected ecosystem
Transport and power remain the largest areas of infrastructure investment. Together they are expected to account for around half of global infrastructure spending through 2050.
Transport investment is forecast to increase from US$1.4 trillion annually to US$2.4 trillion. Annual investment in power infrastructure is projected to grow from US$631 billion to approximately US$1.1 trillion.
The defining characteristic of this investment cycle is the growing interdependence between sectors.
Electric vehicle adoption increases demand for charging infrastructure and stronger electricity networks. Data centers require reliable access to large volumes of power. Renewable generation depends on expanded transmission capacity and large-scale energy storage to maintain grid stability. Industrial automation also increases demand for electricity and digital connectivity.
PwC expects annual investment in power storage to be almost four times higher by 2050, while spending on electricity transmission and distribution is projected to increase by a factor of 2.6.
Infrastructure can no longer be planned as separate transport, energy and digital projects. Decisions in one area increasingly influence investment across the others.
For engineering firms, manufacturers, utilities and technology providers, this creates opportunities that extend well beyond traditional construction. Capabilities in digital integration, systems engineering and operational efficiency are becoming increasingly valuable.
Regional investment priorities are diverging while the global opportunity continues to expand
Infrastructure investment is expected to increase across every major region, although priorities differ.
Asia-Pacific is forecast to account for more than half of global infrastructure investment through 2050, supported by urbanization, industrial expansion and population growth. Africa is expected to record the fastest growth rate as investment accelerates across transport, utilities and public services.
Europe and North America face a different challenge. Much of the investment will focus on renewing aging infrastructure, modernizing electricity networks and improving resilience instead of building entirely new systems.
Geopolitical developments are also influencing priorities. Defense infrastructure is forecast to become one of the fastest-growing sectors as governments strengthen national resilience and supply chain security. The definition of infrastructure is expanding beyond transport and utilities to include assets that support economic competitiveness and national security.
For businesses across construction, manufacturing, logistics and industrial technology, these trends suggest sustained demand rather than a temporary increase in activity. Long-term infrastructure programs create opportunities throughout supply chains, from construction materials and specialist equipment to automation, software and engineering services.
Governments and investors are also placing greater emphasis on asset performance, lifecycle management and resilience against climate, cyber and operational risks. Infrastructure planning is becoming increasingly data-driven, with success measured by long-term performance as much as initial delivery.
Long-term forecasts cannot predict every economic or political development. They can, however, provide a valuable framework for understanding where investment priorities are heading. As artificial intelligence, electrification and digital connectivity reshape economies, infrastructure is evolving from a collection of individual assets into connected systems designed to support productivity, resilience and sustainable growth for decades to come.
