You probably don’t think about infrastructure when you flip on the lights, join the morning commute, or stream, scroll, and swipe through your day. Infrastructure fades into the background, until a pothole turns a routine drive into a repair bill, a dead zone drops your meeting mid-sentence, or a blackout shuts down operations. But the changes coming to the backbone of the modern global economy will be hard to ignore.
In a world increasingly dependent on electrification, data, automation, and circular resource flows, infrastructure will no longer be defined solely by roads, bridges, power grids, or plants. It will span the digital, environmental, industrial, and social systems that underpin productivity and human well-being. The PwC-Oxford Economics Global Infrastructure Outlook, 2025-50, estimates in real terms a cumulative $151.1 trillion in investments will be needed to build and maintain the world’s infrastructure in the coming decades.
That includes a baseline forecast of $32.7 trillion for investment in the US, rising to $42 trillion for “desired” benchmark spending that would put the US on par with high-performing peers across all sectors. The baseline spend equates to 4.3% of the estimated 2050 GDP, up from 3.3% in 2024. At nearly 22% of the world’s spending, more than one in every five dollars may be invested in the US. This investment tidal wave signals the infrastructure lifecycle—and the stakeholders involved at every stage—will need to fundamentally evolve.
- CFOs and operating teams responsible for planning, building, delivering and running these assets will face unprecedented pressure to manage complex, interdependent portfolios of new and existing assets that support growth, resilience, and decarbonization simultaneously, all while maintaining cost discipline and long-term asset performance.
- Infrastructure investors, meanwhile, will need to recalibrate their playbooks as the shift in asset classes, risk profiles, and operational demands of modern infrastructure transform every stage of the investment process, from deal execution through active ownership and exit.
Both investors and owners share a common challenge: navigating this new volume and complexity of capital decisions while making sure every dollar delivers.
Below, we outline strategic areas for investors and owners to focus on in this once-in-a-generation investment cycle. We also take a deeper look at the report’s findings, including the key categories of US infrastructure that will likely need investment in the coming decades.
More projects. Much more complexity. How investors and owners can deliver at scale.
The report's infrastructure investment numbers are attention-grabbing. But here's the challenge that doesn't show up in the forecast data: infrastructure investors and owners face fundamentally different but equally complex realities. These realities are compounded by two imposing forces. First, the unprecedented level of capital. Second, the need for interoperability across systems, labor, technologies, and organizational processes when multiple stakeholders and funding sources are all part of a major project.
In this business environment, Infrastructure investors—funds, private equity, and institutional capital—must deploy billions across diversified portfolios while managing risk-return profiles, shifting regulatory requirements, and stakeholder expectations at an unprecedented scale. Infrastructure owners/builders—utilities, developers, hyperscalers, and engineering and construction firms—are simultaneously delivering multiple megaprojects across sectors and geographies while tightening capital allocation and meeting rising transparency demands. These are dependencies many companies haven’t managed before and make the complexity much greater.
Companies need collaboration across engineering, technology, finance, tax, procurement, and sustainability at a portfolio scale. This is the defining challenge of the infrastructure super-cycle. The organizations that navigate it will do so by transforming capital strategy into a disciplined, repeatable engine capable of delivering outcomes at scale and speed, whether that's advancing returns across investment platforms or executing growth strategies through infrastructure delivery.
For infrastructure investors this means:
For infrastructure owners this means:
AI, power, roads, and an aging population: The forces reshaping US infrastructure investment through 2050.
The once-in-a-generation rewiring of the modern economy isn’t evenly distributed. In the Americas, one market sets the pace: the US.
The report covers five countries in the region—Brazil, Canada, Chile, Mexico, and the US—which together account for 95% of the area’s economic output and are forecast to grow annual infrastructure investment from $1.2 trillion in 2024 to nearly $1.9 trillion by 2050, a 57% increase.
The US accounts for more than 75% of the Americas. Annual US infrastructure spending is forecast to climb from $952 billion in 2024 to $1.5 trillion by 2050, up 60%. Over the next 25 years:
- Road and bridge projects will continue to be one of the largest categories of infrastructure, accounting for 18.3% of US investments. While capital will be spent on routine maintenance, new road systems will carry autonomous vehicles and embed abilities like dynamic pricing and wireless charging.
- As AI adoption explodes, there is a short, highly capital-intensive data center build out phase, with investment jumping 116% between 2024 and 2027. But like the build out of railroads or fiber optics, we anticipate this frenzy of activity eventually moderating in the 2030s and beyond. Cumulative data center investment may hit $1.4 trillion by 2050.
- The growth of the digital economy will spur significant upgrades to power grids across the US. Our research shows a cumulative $7.7 trillion is needed, with low cost, low emissions renewable energy and new transmission and distribution systems likely accounting for 87% of total power investments.
The following four infrastructure segments are expected to account for most of the spending. Other categories such as water, resources, defense, and industrial manufacturing are also expected to need significant investment. The forecasted data is adjusted for inflation.

Power: New energy assets to enable digital infrastructure
US financial snapshot
- Annual spending in 2024: $153.2 billion
- Projected annual spending in 2050: $371.2 billion
- 25-year CAGR: 3.2%
- Increase in annual spending by 2050: 121%
- Cumulative spending by 2050: $7.7 trillion
Power infrastructure includes the fixed assets and structures used for the generation, storage, and distribution of electricity, including low cost, low emissions renewables, fossil fuel, nuclear power plants (with growing momentum behind small modular reactors), transmission and distribution (T&D), and battery storage. The US power grid needs substantial investment in the coming decades to support a projected 150% increase in electricity demand from the data center boom, the exploding energy demands of AI, and advanced manufacturing.1 And all options are on the table, from renewables and microgrids to storage and new nuclear energy generation.
Forces reshaping US infrastructure investment Transport
Transport: Investing to keep the US moving
US financial snapshot
- Annual spending in 2024: $206.4 billion
- Projected annual spending in 2050: $342.9 billion
- 25-year CAGR: 2.0%
- Increase in annual spending by 2050: 66%
- Cumulative spending by 2050: $7.2 trillion
More people moving around will require substantial investment in transport infrastructure, including the renewal of existing assets, as well as the maintenance and construction of new roads, bridges, tunnels, railways, airports, ports, and marine works. The investment picture reflects a system under pressure from two directions—decades of deferred maintenance on one side, surging demand on the other. Roads and bridges bear the heaviest investment, followed by rail, which is driven by urbanization. These investments reflect the sheer scale of keeping the arteries of the US economy open and functioning.
Digital technologies play a critical enabling role. The convergence of digital and physical infrastructure will create the resilient and sustainable mobility systems of tomorrow. These transport systems will comprise integrated, multimodal infrastructure, combining roads, rail, ports, airports, and digital networks. Smart ports and airports will become engines of economic dynamism by employing automation, data analytics, and low-carbon technologies to improve efficiency and sustainability.

Digital: The defining asset class in the 21st century
US financial snapshot
- Annual spending in 2024: $82.3 billion
- Projected annual spending in 2050: $105.6 billion
- 25-year CAGR: 1%
- Increase in annual spending by 2050: 28%
- Cumulative spending by 2050: $2.4 trillion
Networks, fiber, servers, towers, satellites, and data centers are the physical environments in which computation takes place. They are becoming the defining infrastructure of the 21st century.
Rapidly growing demand for data and digital services will drive strong investment in data center capacity over the next 25 years. In the second half of the 2020s, decades of expansion will be concentrated into a short, highly capital-intensive build-out phase. Between 2024 and 2027, annual investment in data center infrastructure will rise by 116%, from $53.2 billion to $118.4 billion. Hyperscale campuses, colocation facilities, and edge sites will be delivered at speed to meet the surging demand created by steady cloud growth, the rapid adoption of generative AI, and expectations for more compute-intensive AI applications and workloads.
As new facilities come online to accommodate rising demand, the rate of constructing additional structures will slow throughout the 2030s. By the 2040s, as the market reaches maturity, investments in buildings and infrastructure will stabilize. Looking further ahead, data center investment will shift away from expanding overall capacity and instead concentrate on maximizing the efficiency, flexibility, and utilization of existing assets.
Forces reshaping US infrastructure investment Social
Social: An aging population will put pressure on this often-underestimated asset class
US financial snapshot
- Annual spending in 2024: $203.6 billion
- Projected annual spending in 2050: $332.4 billion
- 25-year CAGR: 2.0%
- Increase in annual spending by 2050: 65%
- Cumulative spending by 2050: $6.6 trillion
Social encompasses healthcare, aged care, and education facilities. The investment case for this asset class isn’t driven by technology disruption or the energy transition. It’s driven by something far more predictable and unavoidable: populations are growing, people are aging, and the systems to serve them need to keep pace. Health and aged care are where the urgency is most acute. That is no accident. The growth of the population age 65 and over is forecasted to outpace younger generations in the coming decades.2 That’s a demographic wave that will place sustained and significant pressure on hospitals, care facilities, and the broader health infrastructure that supports them.
The next economy is being built right now. Will your capital strategy be ready?
The PwC-Oxford Economics Global Infrastructure Outlook makes one thing clear: investment is needed. But there isn’t unlimited investment capital or resources to deploy that capital. Companies that align capital programs with strategy and effectively deploy AI and other technologies can strengthen scheduling, forecasting and execution, leading to improved project efficiency, less cost overruns, and greater value.
