Overview
- IDC’s Quarterly Ethernet Switch Tracker reported on Friday that Nvidia reached $2.1 billion in data‑center switching revenue in Q1 2026, giving it roughly a 21.5% share and the top revenue position in the segment.
- Nvidia’s switching revenue rose 192.7% year over year as customers bought its Spectrum‑X bundle, which pairs Spectrum switches with BlueField DPUs and LinkX cabling to link large GPU clusters for training and inference workloads.
- The data‑center switching market expanded rapidly, growing 61% year over year to $10 billion in Q1 2026 while the overall Ethernet switch market rose 39.8% to $15.4 billion on strong AI infrastructure demand.
- IDC warned that Cisco, Arista, and Broadcom are likely to mount competitive responses in data‑center switching and that tariffs, regional economic shifts, and component price moves could slow parts of the market.
- The shift changes how cloud builders buy networks and could push more bundled hardware and software deals, affect vendor margins and supply chains, and help explain a modest boost in Nvidia shares on the data release.
