NVIDIA’s AI footprint keeps expanding! Data center Ethernet switch revenue surges 193%, quietly taking the No. 1 spot globally.

Nvidia's AI expansion has extended from chips to the entire network.

According to the latest IDC data, Nvidia became the global revenue leader in the data center Ethernet switch market for the first time in the first quarter of fiscal year 2026 (Q1 2026). This is a field traditionally dominated by networking giants such as Broadcom and Cisco.

IDC data shows that Nvidia's Ethernet switch revenue in that quarter reached $2.1 billion, a year-over-year increase of 192.7%, with market share rising to 21.5%. IDC noted, "The most critical highlight of Q1 2026 is Nvidia's ascension to the top of the data center Ethernet switch market."

This result directly reshapes the competitive landscape of the data center networking industry.

Spectrum-X: Nvidia's "Network Weapon"

Nvidia's victory this time relies on the Spectrum-X platform.

Spectrum-X is not a single product but an end-to-end network solution, encompassing BlueField DPUs (Data Processing Units) and NVIDIA LinkX cables, designed specifically for large-scale GPU clusters.

Simply put, the logic of this system is: AI training requires tens of thousands of GPUs to work together, and the communication speed between GPUs directly determines training efficiency. Spectrum-X is specifically built for this "GPU internal highway."

IDC stated that Spectrum-X "captures the demand from hyperscale cloud providers and enterprise customers for AI factory network infrastructure through the co-design of GPUs and networks." In other words, customers who buy Nvidia GPUs also end up buying Nvidia's networking — the ecosystem lock-in effect is becoming evident.

The Market is Expanding Rapidly

Nvidia's rise occurs within a rapidly expanding market.

According to IDC, the global data center Ethernet switch market revenue in Q1 2026 reached $15.4 billion, a year-over-year increase of 39.8%. Among this, hyperscale cloud providers and enterprise data centers collectively contributed $10 billion, a year-over-year increase of 61%.

By region, the Americas grew the fastest, with a year-over-year increase of 49.7%; Europe, the Middle East, and Africa (EMEA) grew by 32.2%; and Asia-Pacific (APAC) grew by 25.9%.

Demand for high-speed switches is particularly strong. In Q1 2026, 800G switches already accounted for 35.8% of data center revenue share, while 200G and 400G switches together accounted for 34.1%, collectively contributing about 70% of global data center Ethernet revenue.

From GPU to Network: Nvidia's Full-Stack Ambition

This is not the first time Nvidia has ventured beyond the GPU field. Previously, Nvidia announced the advancement of its Vera CPU business and plans to increase optical connectivity manufacturing capacity in the U.S. by 10 times through collaboration with Corning.

Now, topping the Ethernet switch market means Nvidia is extending its reach into every aspect of AI infrastructure — from GPUs and CPUs to the networks connecting them.

IDC data indicates that this "structural shift is reshaping the vendor landscape of the entire data center networking industry." For Nvidia's competitors, this is not just a matter of market share but a competition at the ecosystem level.
