AI Demand Ignites Datacenter Switch Market as Q1 Revenue Soars 32% to $11.7B

Networks AI Sparks Surge in Datacenter Switch Market

The datacenter network switch market, long quiet, has suddenly come alive thanks to AI-driven demand. Analyst firm IDC reported $11.7 billion in switch revenue for Q1 2025, marking a 32.3% increase from the previous year. This surge is fueled by the need for high-bandwidth, low-latency networks to support AI workloads.

Datacenter Switch Revenue Accelerates Rapidly

IDC noted a 54.7% growth in datacenter switch revenue during Q1, accelerating from the 32.1% growth seen in Q4 2024. The rise is largely due to the deployment of 200/400 GbE switches, which saw a 189.7% year-over-year jump. Additionally, 800 GbE switches entered the market strongly, generating $350.8 million and capturing 5% of the total market in their debut quarter.

Vendor Performance Highlights

• Nvidia led the pack, with datacenter switch revenue soaring 760.3% year-over-year to $1.46 billion. Between Q4 2024 and Q1 2025 alone, Nvidia’s revenue grew 183.7%.
• Arista also posted solid gains, with datacenter switch revenue up 27.1% year-over-year to $1.6 billion.
• Cisco, however, saw a 3.2% decline in datacenter switch revenue, even as its overall switch revenue rose by 4.7%, indicating it’s losing ground in this fast-growing segment.

Campus and Branch Network Switches See Moderate Growth

While datacenter switches are booming, campus and branch network switches grew at a more modest pace of 9.6%. This indicates steady demand outside of datacenter environments, but nothing close to the AI-driven spike seen in core infrastructure.

Wireless LAN Market Shows Stabilization with AI Innovations

IDC also reported a 10.6% growth in wireless LAN revenue for Q1. The wireless market is stabilizing after supply chain disruptions caused by the COVID-19 pandemic. AI continues to influence this space, with new technologies like 6 GHz Wi-Fi and AI-powered management tools driving next-generation wireless connectivity.
