NVIDIA Claims Top Spot in Datacenter Switching Market as AI Infrastructure Spend Drives Ethernet Hardware Revenue to Historic Milestones
A historic milestone for the world's networking industry has been reached. Thanks to recent data published in IDC Quarterly Ethernet Switch Tracker, the world's Ethernet switch market closed at $15.4 Billion in Q1 2026, a 39.8% decline from the same period a year earlier. The wild growth was concentrated in the datacenter category, which shot up 61% from the previous year, closing at $10 Billion in revenue.
This unprecedented growth was driven by enormous capital investments targeted towards artificial intelligence infrastructure for large scale training and inferencing workloads.
It is within this growth environment that NVIDIA has passed in the ranks, displacing the usual audio loudmouths, to be listed as the top revenue generating vendor in the datacenter switching market.
The build out of computational clusters by hyperscalers, cloud providers and large enterprises has also driven the concentration of spend on ultra high speed hardware. According to IDC data, 800G switches made up 35.8% of all datacenter switching revenue in the quarter. At the same time, 200Gb and 400Gb port speeds made up 34.1%.
Together these platforms made up almost 70% of all datacenter Ethernet switch spend. This concentration of hardware spend clearly reflects the industry move to extremely integrated, low latency network fabrics needed to connect large GPU clusters.
Outside of the datacenter, enterprise campus & branch switching segment generated a more conservative but still healthy 12.3 % CAGR growth rate over previous year equating to a figure of 5,400,000,000 dollars. Existing non datacenter growth is being driven by a combination of 2 market mechanisms. 1. Organizations are on a heavy hardware refresh budget replacing aging/inflexible network infrastructure; 2. The chronic storage shortage problem for memory components has caused an inflation of the average selling prices for switching hardware, boosting revenues even though the overall shipment volumes are fairly restrained.
In terms of regions, across all major markets, every had a positive quarter. The Americas topped the world with a 49.7% YOY revenue increase, buoyed heavily by the high concentration of hyperscaler AI projects present in North America. Europe, Middle East and Africa (EMEA) and Asia Pacific markets grew 32.2% and 25.9% respectively.
Meanwhile, the worldwide router market gained good traction, amounting to $3.8 billion in total value, representing an overall growth of 11.3% YoY. Service provider telecommunications and cloud infrastructure accounted for 77.2% of it, or 2.9 billion dollars. The remaining 867 million dollars came from the enterprise routing space, which saw a growth of 6.1%, with companies upgrading to SD WAN architecture for their wide area network.
Cisco Systems maintained its place as the largest overall networking vendor by netting 4,500,000,000 dollars in switching and earning a 29.3% share of market for the year. Switching sales for Cisco increased by 24%, campus business increased by 14.1% and datacenter business jumped 43% thanks to the high demand in AI. Cisco also gained a 35.1% share of the routing market earning the company a 24.4% rise in router revenue.
NVIDIA reached a new record when its switching revenue, which is entirely generated from the datacenter segment, skyrocketed 192.7% to 2100000000 dollars. This brought them a share of 21.5% in the datacenter segment. The drivers behind that success was the speedy uptake of its Spectrum X networking platform. This system integrates Ethernet switches with BlueField data processing units and purpose bulit cabling, establishing itself as a preferred interconnect for large scale GPU deployments, AI factories.
Arista Networks Switching revenue $2,200,000,000 up 37.3% YoY Arista has a 14.6% share of the total switching market, and a 20.7% share of the datacenter switching market. Arista will continue to be a very competitive source of hardware for some large hyperscale customers at the 400G and 800G level.
Huawei posted $895,000,000 in Ethernet switch revenues, an increase of 27.2% and a market share of 5.8%. A 25.4% share of the global router market was obtained, as demand was steady from service providers in China and several other emerging markets.
Hewlett Packard Enterprise data showed that it had 985 Million Dollars127.4 switching revenue (this is the percentage increase and market share ). These totals now include existing business from (who was bought in July 2025) and their this enhances the combined company's ability to meet the continuing demand for campus and branch refresh cycles.
The proliferation of dedicated hardware has turned the established vendor dynamics upside down, says Paul Nicholson, Research Vice President of Cloud and Datacenter Networks at IDC
"NVIDIA reaching #1 in datacenter Ethernet switching in just one year stands as one of the key vendor landscape shifts IDC has observed in enterprise networking. Spectrum X's integrated GPU + networking play is drawing AI factory wins that traditional networking vendors can't take alone with generic hardware. On the campus side, the story is different, but just as resonant: the refresh wave is indeed here, but be prepared for ASP normalization, likely once memory supply constraints begin to loosen. Budget for the eventual transition today, before prices shift."
For enterprise IT buyers, the challenge is to manage what may be needed in the short term versus supply chain volatility. According to Brandon Butler, Senior Research Manager of Network Infrastructure and Services at IDC, the key factors driving campus decision
"Enterprise campus and branch ethernet switching growth is supported by many trends: First, large enterprise campus and branch networks are being modernized on a multi year refresh cycle to adopt Wi Fi 7 and to deliver faster speeds at the access, distribution and core tier of the network. AI, security and IoT are other big trends. On the flip side, memory driven supply chain headwinds are to be monitored."
Moving forward, the competitive struggle of the datacenter segment is likely to become fiercer, as traditional vendors such as Cisco, Arista, Broadcom ecosystem partners will introduce direct hardware rivals against the new market leader NVIDIA's.
