Summary
IDC said Nvidia became the top data center Ethernet switch vendor by revenue in Q1 2026, taking 21.5% of the market and overtaking Arista's 20.7%.
The lead came as Nvidia's Spectrum-X system gained traction with cloud companies building AI data centers quickly and buying networking alongside AI chips.
The $10 billion switch market grew 61% from a year earlier, giving Nvidia room to expand from just 4% share in Q1 2024.
Jensen Huang said Wednesday that Spectrum-X is now larger than all other Ethernet networking peers combined, after Nvidia earlier reported broader data center networking revenue tripled to $15 billion.
Nvidia's edge still faces limits as cloud giants diversify suppliers and enterprises lean on incumbent networking vendors even after Mellanox gave Nvidia an early foothold.
Can legacy networking giants survive by selling parts, or must they build competing full-stack AI solutions to challenge Nvidia's dominance?
As Nvidia's AI stack dominates, are cloud giants building an infrastructure bubble that is destined to pop and disrupt the market?
