Description

Global digital infrastructure investment has entered an unprecedented era of expansion, driven by the convergence of artificial intelligence workloads, cloud computing proliferation, and the worldwide imperative for high-speed connectivity. Infrastructure investment needs are projected to exceed $100 trillion by 2040, with digital infrastructure commanding a rapidly increasing share of total capital deployment across every major geography. The year 2025 was a watershed moment: digital infrastructure overtook all other infrastructure sectors by transaction volume for the first time, with four hyperscale companies—Amazon, Google, Meta, and Microsoft—collectively investing over $416 billion in capital expenditures, a 66% increase from $251 billion in 2024.

The AI-driven capital supercycle is reshaping the data center industry, with hyperscaler capital expenditures projected to reach $610 billion in 2026 and the data center equipment market expected to hit $1 trillion by 2030. Beyond data centers, fiber optic networks, 5G infrastructure, and submarine cable systems are experiencing massive investment flows as nations compete for digital sovereignty and connectivity leadership. The report identifies five macro investment themes: hyperscale cloud and AI data center buildout, fiber-to-the-home and 5G backhaul expansion, next-generation wireless network deployment, submarine cable system construction, and the growing intersection of power infrastructure and digital capacity.

This report provides a comprehensive analysis of the global digital infrastructure investment landscape, covering total addressable market sizing and growth drivers, sector-by-sector breakdowns of data centers, fiber optic networks, 5G infrastructure, and submarine cables, regional dynamics across North America, Europe, Asia-Pacific, and emerging markets, power and sustainability challenges facing the sector, key risks and headwinds, and strategic outlook with investment thesis projections through 2030. The analysis serves institutional investors, infrastructure operators, and policymakers evaluating digital infrastructure as an asset class.

How Do Licenses Work?

How Do Licenses Work?

The primary function of a report license is to define how many people within a company are authorized to use the purchased report. This is separate to how a report might be delivered. Unless specifically identified otherwise, the purchase option is Single User. Below is a helpful description of that license, along with a sampling of others most commonly offered.

  • This license allows only one user to have access to and to use/read the report. It is not one user at a time or one user group; it is an individual who will be reading and utilizing the report.

  • This license allows for the entire purchasing company to read and use the report. This is the license level that would allow for a report to be placed on an internal company shared drive for access by all employees of that direct company. This license does not extend to parent or sister company use.

  • This license is designed to allow an entire department within a company full access to a report. The departmental license is a great option for companies that have more than one location and the department is spread out all over the country/world

  • This license is for companies that have one location where they want the report to be accessible by all employees within that physical location.

  • This is the most flexible of the licensing options. Some publishers will allow you to get a license for a preset number of people (typically 5). These licenses are ideal for small work groups.

License options are at the discretion of each publisher. As such, not all licenses indicated above are available for every product. If you are uncertain of the best license for your needs or would like a license that is not proactively available, please contact us and we will be happy to assist.
