NVIDIA Leads Global Datacenter Ethernet Switch Market Amid AI Surge

The worldwide Ethernet switch market grew 39.8% year‑on‑year to $15.4 billion, with the datacenter segment expanding 61% to $10 billion, driven by massive investments in AI infrastructure for training and inference workloads. NVIDIA’s revenue in datacenter Ethernet switching jumped 192.7% to $2.1 billion, giving it a 21.5% share of the datacenter segment and its first top‑ranking position. The growth is powered by NVIDIA’s Spectrum‑X platform, which integrates Spectrum Ethernet switches, BlueField DPUs and NVIDIA‑LinkX cables for large GPU clusters, and the newer Spectrum‑6 SN6000 series that uses co‑packaged optics and hardware‑accelerated multilane networking to double lane bandwidth for AI‑focused “fabric” factories. Existing rivals remain significant: Cisco retains overall market leadership with a 29.3% share and $4.5 billion revenue, while Arista holds a 14.6% share overall and 20.7% in the datacenter segment. Within datacenters, 800‑gigabit switches accounted for 35.8% of revenue, outpacing 200‑ and 400‑gigabit units. IDC expects the Ethernet‑switch market to maintain its momentum through 2026 as AI‑driven demand continues.
