North America 5G Core Network Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

North America 5G Core Network Market Trends and Insights

Standalone 5G Rollouts Reach an Inflection Point

AT&T and Verizon launched standalone cores in late 2025, joining T-Mobile and giving all 3 United States Tier-1 carriers commercially differentiated standalone services. This shift increased pressure to move subscribers and service development onto standalone architectures. AT&T described its platform as an open, virtualized architecture that runs across Microsoft Azure and its own data centers. VTel Wireless selected Ericsson in March 2026 for a dual-mode 5G core and radio access network that supports end-to-end standalone Voice over New Radio roaming with nationwide providers. This demonstrates that the North America 5G core network market is extending beyond large urban carriers. ATIS identified limited dedicated spectrum and the remaining economics of non-standalone upgrades as important barriers for smaller carriers.

Cloud-Native Core Adoption Across North American Operators

Cloud-native core adoption has progressed from a strategic objective to an operating model among major regional operators. Software can be deployed on Kubernetes-compatible infrastructure, which broadens the supplier base to include software vendors, systems integrators, and cloud platform providers. Ericsson launched its On-Demand 5G Core-as-a-Service platform with Google Cloud in June 2025.^{[1]Ericsson and Google Cloud, “Ericsson and Google Cloud Team Up to Deliver Carrier-Grade 5G Core-as-a-Service, Built with AI at the Foundation,” Google Cloud Press Corner, googlecloudpresscorner.com} Boost Mobile deployed Nokia's cloud-native 5G Voice Core on a public cloud in March 2025 and consolidated multiple IMS voice functions into 1 cloud-native network function. Mavenir reported that 82% of surveyed operators either operated cloud-native cores or planned to do so by the end of 2026. The North America 5G core network market, therefore, has a wider range of implementation models, but operators still need the skills to manage them.

Enterprise Private 5G Demand in Manufacturing and Logistics

Private 5G is moving from limited pilots into multi-site infrastructure programs, particularly in manufacturing and logistics. Citizens Broadband Radio Service spectrum gives United States enterprises a cost advantage for private deployment compared with countries that require premium industrial spectrum licenses. NTT DATA announced in February 2026 that Cargill's private 5G network had reached 50 sites, largely in the United States. The program supports connected robotics, automation, and digital operations, with more sites planned during 2026. These deployments require dedicated standalone core platforms rather than merely moving consumer traffic off public networks. Manufacturing, energy and utilities, transportation and logistics, public safety and emergency services, and smart cities and municipalities each create separate integration and support requirements for the North America 5G core network market.

Network Slicing Requirements for Mission-Critical Services

Network slicing is becoming a commercial feature for mission-critical communications, with public safety providing the most visible use case. AT&T and the First Responder Network Authority activated a dedicated FirstNet 5G standalone core in July 2026. The core is physically separate from AT&T's commercial infrastructure and serves more than 27,500 public-safety agencies and 5.5 million connections across 56 United States states and territories. The investment exceeded USD 8 billion, including a USD 6.3 billion network contract and a USD 2 billion commitment announced in March 2026. AT&T, Verizon, and T-Mobile now offer distinct mission-critical slice products, increasing the need for standards work and interoperability through 2031. Rogers, Bell, and Telus tested slicing applications for broadcast, public safety, and first responders during 2025, while Bell's 5G+ Advanced standalone core supports future service differentiation.^{[2]Bell Canada, “Bell Introduces 5G+ Advanced, Its Fastest and Most Advanced Network Yet,” BCE Newsroom, bce.ca}

High Upfront Core Modernization Costs

Core modernization places pressure on carriers of all sizes to reduce capital and operating costs. Regional and rural carriers often face similar per-site integration costs to those of Tier-1 operators, despite having smaller subscriber bases. Running Evolved Packet Core and 5G core stacks during a multi-year migration can also raise post-migration support costs. Mexico faces further uncertainty because Congress sets spectrum fees annually. AT&T Mexico indicated that it might not participate in the upcoming industrial 5G spectrum auction. Mavenir found that planned standalone adoption depends on vendors providing credible total cost of ownership evidence for cloud-native core migration.

Legacy EPC Integration Complexity

Parallel Evolved Packet Core and 5G core networks make migration schedules more difficult to execute. Ericsson noted that migration from EPS to 5GS requires user data and policies to support 2 networks while maintaining inbound roaming services. Telus built its own cloud-native stack to maintain consistency across a multi-vendor environment, showing the engineering effort needed to migrate legacy customers without reducing service quality. A single-vendor cloud platform can simplify operations, but it can also increase vendor dependence. A horizontal cloud environment improves flexibility but raises design and skills requirements. The Federal Communications Commission's equipment authorization supply-chain security rules add another compliance consideration to supplier selection.^{[3]Federal Communications Commission, “Protecting Against National Security Threats to the Communications Supply Chain Through the Equipment Authorization Program,” Federal Register, federalregister.gov}

Segment Analysis

By Component: Services Point to a Shift Toward Managed Operations

Solutions accounted for 63.55% of the North America 5G core network market revenue in 2025. The segment includes packet-core software, network function virtualization infrastructure, and orchestration and management platforms. Its position reflected software-led spending on Tier-1 standalone buildouts by AT&T, Verizon, T-Mobile, Bell, Rogers, and Telus. Packet-core software remained central because operators need cloud-native network functions to replace hardware-based legacy systems.

Services in the North America 5G core network market are projected to expand at a 21.21% CAGR through 2031. The segment covers integration and deployment, consulting and advisory, and support and maintenance. Cloud-native standalone cores require frequent software updates, while operators continue to face a shortage of cloud-native operations skills. Ericsson agreed in April 2025 to deploy and operate a dual-mode 5G core for GCI Communication Corp in Alaska, including cloud-core technology, AI tools, and ongoing network management. Support and maintenance demand is expected to continue as operators retire parallel Evolved Packet Core systems.

By Deployment Model: On-Premise Control Competes With Public Cloud Flexibility

On-Premise/Dedicated deployments accounted for 51.95% of North America's 5G core network market revenue in 2025. Operators and enterprises selected this model when they required low latency, data-handling compliance, and infrastructure control. Dedicated deployments are particularly relevant for factory environments with strict service-level requirements. Verizon's Intelligent Edge Network strategy reflects its preference for end-to-end ownership in critical core areas and Level 4 autonomy.

Public Cloud in the North America 5G core network market is projected to expand at a 24.76% CAGR through 2031. AT&T deployed its nationwide standalone core on Microsoft Azure in October 2025, running more than 60 containerized network functions for hundreds of millions of subscribers. This deployment demonstrated that public cloud infrastructure can meet Tier-1-scale and reliability requirements. Ericsson's platform with Google Cloud gives carriers a managed option when internal cloud engineering capacity is limited. Hybrid and Telco Edge Cloud combines local infrastructure with cloud-native orchestration and is relevant to mid-tier Canadian and Mexican operators, helping them replace legacy packet-core systems.

By End-User: Enterprise Private 5G Adds Demand Beyond Carriers

Telecom Operators accounted for 76.45% of the North America 5G core network market revenue in 2025. This result reflected carrier-led spending during the first standalone build cycle. The group includes Tier-1 carriers and regional operators purchasing network functions, managed operations, orchestration licenses, and lifecycle management. User Plane Function distribution, Policy Control Function modernization, and network slicing remain important areas of operator spending.

Enterprises in the North America 5G core network market are projected to expand at a 24.26% CAGR through 2031. Manufacturing and logistics are the most developed enterprise deployment areas. NTT DATA reported that Cargill reduced cabling and setup costs by 70% compared with comparable Wi-Fi infrastructure across its 50-site private 5G program. Energy and utilities use private 5G for remote monitoring and automation, while transportation and logistics use it for asset tracking and autonomous vehicle infrastructure. Public safety, emergency agencies, smart cities, and municipalities use it for mission-critical and sensor-dense systems, supported by 3GPP Release 15-17 specifications and O-RAN Alliance frameworks.

By Network Function: UPF Supports Traffic and NEF Enables Service Exposure

User Plane Function held 22.10% of the North America 5G core network market revenue in 2025. Every standalone core requires it for data-plane session anchoring, traffic routing, and quality-of-service enforcement. Operators add distributed edge instances as standalone subscribers, and as data traffic increases, this reduces latency for enterprise and consumer applications. NEC demonstrated in February 2026 that agentic AI could manage the full User Plane Function lifecycle from design through operational monitoring and reduce deployment time from several weeks to hours.

Network Exposure Function is projected to expand at a 27.98% CAGR through 2031. It exposes quality-of-service controls, location services, and network analytics through standardized application programming interfaces. T-Mobile outlined plans for 2026 to enable enterprise customers to create end-to-end network slices via API-driven provisioning. Oracle's cloud-native Policy Control Function supports continuous deployment pipelines and 4G-to-5G policy migration. Access and Mobility Management Function, Session Management Function, Network Slice Selection Function, Unified Data Management, Authentication Server Function, Network Repository Function, and Application Function provide related control-plane and data-management roles.

Geography Analysis

The United States held 86.50% of the North America 5G core network market share in 2025. Nationwide standalone deployments by the 3 Tier-1 carriers supported its position. The federal first-responder core investment exceeded USD 8 billion. The country also has the region's broadest private 5G pipeline. FirstNet activated a dedicated 5G standalone core in July 2026 for more than 27,500 agencies across 56 states and territories. Citizens Broadband Radio Service spectrum also lowers private 5G entry costs for enterprises.

Canada retained the second-largest regional position in 2025. Bell launched its 5G+ Advanced network on a new standalone core in March 2026. It provided theoretical peak download speeds of 4.3 Gbps across the Greater Toronto and Hamilton Area. Telus continued its Ericsson core migration and developed a cloud-native orchestration stack for a multi-vendor environment. Samsung deployed a 5G Non-Standalone core and a 4G LTE Core Gateway for Videotron in February 2026. Bell and Nokia also expanded their Cloud RAN and Open RAN partnership in February 2025.

Mexico is projected to expand at a 21.30% CAGR through 2031. The earlier stage of core modernization leaves substantial scope for operators to move from non-standalone to standalone architectures. América Móvil reported that Telcel ended 2025 with 5G coverage reaching 60% of Mexico's population. AT&T Mexico maintained 5G coverage in 56 cities, while Movistar exited the country, with AT&T becoming its successor. High spectrum costs remain a structural barrier, as documented by GSMA. The planned industrial 5G spectrum auction could support private-network deployment, but spectrum policy is expected to affect investment through 2028.
