The United States data center networking market is projected to grow from USD 8.18 billion in 2025 to USD 10.43 billion
According to a report published by Research and Markets on August 26, 2026, the United States data center networking market is expected to expand from USD 8.18 billion in 2025 to USD 8.52 billion in 2026, reaching USD 10.43 billion by 2031 with a compound annual growth rate of 4.14 percent between 2026 and 2031. This growth is fueled by hyperscale data center expansion, artificial intelligence infrastructure investment, cloud adoption, 5G deployments, and the transition to higher-bandwidth Ethernet networks. Artificial intelligence workloads are prompting hyperscale operators to redesign networks with low-latency, non-blocking fabrics capable of handling intensive east-west traffic for distributed GPU clusters. Meta has adopted Arista 7700R4 platforms for AI training clusters, while major investments from Microsoft and Amazon Web Services are increasing demand for AI-optimized switches, optical components, and network interface cards. Custom silicon from NVIDIA, AMD, and other providers is shaping purchasing strategies toward tightly integrated systems for accelerated computing.
The industry is actively migrating from 100G infrastructure to 400G and 800G Ethernet to prevent link saturation in AI training environments. Broadcom's Tomahawk 6 platform supports 1.6 Tb/s ports to meet future bandwidth needs, and the Ultra Ethernet Consortium ratified UEC 1.0 in June 2025 to improve traffic distribution for large-scale AI environments. However, deployment pacing is constrained by extended lead times for 800G optical modules, which have reached 18 months as manufacturers prioritize high-performance optics for AI infrastructure. Additional headwinds include equipment tariffs that have added an estimated 8 percent to 20 percent to certain networking costs, high capital expenditure required to upgrade legacy 10G and 40G networks, water-usage limits curbing hyperscale expansion, and a scarcity of automation-skilled network engineers. Despite these challenges, edge computing expansion, 5G micro data centers, and state-level energy-efficiency incentives are creating new growth avenues.
In terms of market composition, networking products accounted for 77.60 percent of market revenue in 2025, led by fixed-form-factor Ethernet switches purchased by hyperscale operators. Software-defined networking controllers and network security appliances are gaining traction as organizations implement automated policy management and zero-trust architectures requiring extensive fabric-level micro-segmentation. Data center networking services are projected to grow at a 4.32 percent compound annual growth rate, driven by demand for installation, integration, consulting, maintenance, and managed support amid the complexity of multi-vendor 400G and 800G environments. Providers offering combined hardware, optics, and technical services under outcome-based agreements are well-positioned to capitalize on this trend.
End-user adoption continues to broaden across sectors. IT and telecommunications companies held a 34.15 percent market share in 2025, supported by 5G core deployments and public cloud backbone upgrades. Financial institutions are investing heavily in low-latency connectivity for algorithmic trading, while the manufacturing sector is forecast to record a 5.08 percent compound annual growth rate as Industry 4.0 facilities integrate real-time analytics and robotic production systems. Government and defense agencies are modernizing secure networks for AI model training, healthcare organizations require additional bandwidth for diagnostic imaging and electronic health records, and media companies are expanding capacity to support 4K and 8K production workflows. These diverse applications are transforming the United States data center networking market into a highly diversified, high-performance infrastructure ecosystem.
