Digital Connectivity Infrastructure Market Size, Share & Growth Forecast (2026-2031)

The global Digital Connectivity Infrastructure market is forecast to grow at a CAGR of 1.0%, reaching USD 189.35 billion in 2031 from USD 180.53 billion in 2026.

The 5G and eventual 6G network densification, the hyperscale data center, AI accelerator and high-speed interconnect buildout to help advance cloud and generative AI workloads, and national broadband-equity and universal-service programs filling last-mile fiber and wireless gaps are pulling growth forward simultaneously.

Digital connectivity infrastructure is an overlay of the telecom network infrastructure (access, core and edge) running over the physical compute infrastructure (data centers, colocation, on-premise and hybrid cloud) and the fiber, subsea cable and wireless transport layers that connect them. The term "gigabit access" is often used to denote this new trend, since historically these investment classes were treated separately, but recent developments have seen governments and operators increasingly considering them together in their plans and investment decisions, understanding that gigabit access is only useful if supported by appropriate compute, edge, and interconnection capacity.

Market Dynamics

Market Drivers

• Scaling Generative AI training and inference workloads is creating an unprecedented capital expenditure on data centers, GPUs, liquid cooling systems, and high bandwidth interconnects, and inference workloads now make up more than 50 percent of AI compute need and demand will be geographically distributed.

• Large public broadband-equity and universal service programs are rapidly driving fiber and wireless last-mile deployment in unserved and underserved areas, including the U.S. BEAD program and the European Union's Digital Decade connectivity targets, and activity will peak between 2026 and 2030.

• The continued deployment of 5G, increasing enterprise IT modernization investments and the proliferation of volumes of connected devices are driving demand for access, core, and edge network infrastructure in both developed and emerging markets.

Market Restraints & Opportunities

• Fewer than half of national funding for digital-transformation initiatives is planned to last beyond the end of 2026 in the EU, leading to funding-continuity risk for multi-year infrastructure programmes, and both data centre and fibre deployment timelines are being extended as a result of electrical grid constraints, permitting delays and rising construction costs.

• New investment and deployment opportunities are emerging, however, including the trend towards modular and micro-data-center architectures, private sector capital inflows for digital infrastructure as an asset class and coordinated EU level mechanisms like the European Digital Infrastructure Consortia and Important Projects of Common European Interest, especially in less developed markets and areas where abundant renewable energy can be utilized for the location of facilities.

Market Segmentation

By Infrastructure Layer: Network Infrastructure

Network infrastructure accounts for a significant portion of the market as it forms the backbone of communications between end users, enterprises and data centers, ranging from 5G radio access networks to fiber access networks, core/edge routing and switching equipment, and others.

Cisco Systems manufactures networking equipment, networking software and networking equipment for the edge of the network for enterprise and telecom connectivity infrastructures worldwide.

By Infrastructure Layer: Data Centers & AI Accelerators

The data center and AI accelerator layer is the most rapidly expanding area, as hyperscale cloud vendors scramble to enable their GPUs, liquid-cooled data centers, and high-bandwidth interconnects to support the growing need for AI training and inference.

Amazon Web Services, Microsoft Corporation and Google Cloud Platform are hyperscale data center and cloud infrastructure networks that power compute, storage and AI workload demand around the world.

Colocation and interconnection data center infrastructure for enterprise, cloud and content-deliver connectivity are offered by Equinix and Digital Realty.

By Deployment Model: Fiber-to-the-Premises (FTTP)

FTTP is the most popular buildout approach for last mile connectivity because it is the most future-proof, scalable and capable of multi-gigabit speeds in comparison to fixed wireless and legacy copper solutions, particularly in the context of funding for broadband-equity programs.

In the United States, AT&T, Verizon and Lumen Technologies are growing their fiber deployments to compete for last mile buildout opportunities that are either funded by BEAD or private investment.

Regional Analysis

North America Market Analysis

The largest regional share is in North America, owing to the rapid growth of hyperscale data center investment, and vibrant AI-powered compute demand are driving growth.

Europe Market Analysis

The Digital Decade Policy Programme's 2030 'gigabit and 5G-everywhere' goals are driving Europe forward, with Germany, France, the Netherlands and Nordics exhibiting a strong focus on fibre and data centre investments, though there is a policy focus area for funding continuity beyond 2026.

Asia Pacific Market Analysis

Government-led digital infrastructure initiatives in the Asia-Pacific are quite fast-paced in China, India, Japan, and South Korea, and digital transformation is rapidly accelerating in the enterprise segment due to the adoption of cloud and 5G.

Middle East and Africa Market Analysis

The UAE and Saudi Arabia spearheading the digital transformation in the Middle East, with the region showing the quickest growth as both governments invest heavily in digital infrastructure and smart city initiatives.

South America Market Analysis

Investment in fiber and data centers is also on the rise in South America, with Brazil and Chile leading the way, and hyperscale cloud provider activity in the region growing.

Equinix

Equinix offers enterprises, cloud providers and network operators a comprehensive suite of data center services, including exchanges, infrastructure deployment, and connections to a global facility footprint, for moving traffic and deploying infrastructure anywhere.

Analyst View

The digital connectivity infrastructure market is now two-tracked, with one track being driven by public policy to achieve universal broadband access, and the other track being driven by private capital to scale up in the areas of artificial intelligence and cloud computing. These trends will further merge over the 2026-2031 timeframe, with gigabit last mile, edge computing and hyperscale AI infrastructure all planned as part of the same investment category. The operators and vendors who can meet the demand for grid-capacity constraints, provide modular and quickly deployed infrastructure and are in sync with the public funding timelines are best positioned to seize the coming decade's growth.
