NVIDIA's Networking Revenues Double: Can It Keep the Momentum?
Read MoreHide Full Article
Key Takeaways
NVIDIA's Networking revenues nearly doubled year over year to a record $7.3 billion in Q2.
Strong demand for Spectrum-X Ethernet and InfiniBand drove the segment's momentum.
The unit's revenues are estimated to reach $33.74 billion in FY26, up about 160% YoY.
NVIDIA Corporation’s (NVDA - Free Report) Networking business unit is becoming a critical growth engine as reflected in the company’s last reported financial results for the second quarter of fiscal 2026. Revenues from the Networking business almost doubled on a year-over-year basis and hit a record $7.3 billion in the second quarter, as customers continue to accelerate investments in AI data center infrastructure.
The robust growth reflects how essential low-latency and high-throughput connections are in scaling artificial intelligence (AI) workloads, especially as computing demands grow with reasoning and agentic AI models. Much of the momentum came from strong demand for Spectrum-X Ethernet and InfiniBand solutions.
Spectrum-X has gained traction with cloud providers looking for Ethernet-based AI networking that approaches the performance of InfiniBand while fitting existing infrastructure. At the same time, InfiniBand adoption is expanding among advanced model builders who prioritize the lowest latency and highest efficiency for AI training. NVIDIA also introduced Spectrum-XGS, a new solution designed to connect multiple AI factories, underscoring its ambition to shape large-scale AI networking.
The networking opportunity remains sizable. As hyperscalers and enterprises expand capacity, efficient interconnects can directly improve data center performance. NVIDIA’s integration of networking with its graphics processing units (GPUs) gives it a strong position in the AI data center infrastructure market. The Zacks Consensus Estimate for the Networking business unit is currently pegged at $33.74 billion, indicating year-over-year growth of approximately 160%.
How Competitors Fare Against NVIDIA in AI Networking Space?
NVIDIA faces competition from Broadcom Inc. (AVGO - Free Report) and Arista Networks Inc. (ANET - Free Report) in the AI networking space.
Broadcom has a strong presence in Ethernet switching and custom silicon. Its chips are widely used in large-scale data centers, and its partnerships with cloud service providers give it an edge in delivering networking tailored to specific workloads. As AI infrastructure expands, Broadcom’s focus on efficiency and integration could help it capture more market share.
Known for its high-performance Ethernet switches, Arista Networks has been gaining traction in AI-driven data centers. The company’s strength lies in building scalable, cloud-focused networking systems that can handle the massive data flows required by AI training and inference. While it does not provide GPUs like NVIDIA, Arista Networks’ role in ensuring smooth interconnectivity makes it an important competitor in this space.
