NVIDIA's Spectrum-X Adoption Rises: Will It Boost Networking Revenues?
Read MoreHide Full Article
Key Takeaways
NVDA's networking revenues surged 162% YoY to $8.19 billion in the third quarter of fiscal 2026.
NVDA's Spectrum-X is being deployed by Meta and Oracle to support AI clusters with thousands of GPUs.
NVDA launches Spectrum-XGS to link AI factories, highlighting tighter integration across networking and GPU.
NVIDIA Corporation (NVDA - Free Report) is seeing rising adoption of its Spectrum-X platform as artificial intelligence (AI) data centers grow larger and more complex. Spectrum-X is designed to enhance Ethernet networking performance for AI workloads, enabling graphics processing units (GPUs) exchange data faster and more efficiently. As more customers build large AI clusters, networking has become a critical part of overall system performance, making Spectrum-X an important growth lever for NVIDIA’s networking revenues.
In the third quarter of fiscal 2026, networking revenues surged 162% year over year to $8.19 billion, driven by strong demand for AI data center connectivity. As workloads become larger and more complex, the need for faster, more efficient interconnects is growing, and Spectrum-X is designed to meet that demand.
Cloud service providers and enterprise customers are increasingly deploying Spectrum-X to support training and inference tasks that involve thousands of GPUs. Companies like Meta Platforms, Oracle and CoreWeave are already integrating Spectrum-X to power their next-generation AI data centers. Additionally, other companies like Cisco and Hewlett Packard Enterprise are working with NVIDIA to integrate and offer the Spectrum-X architecture within their product lines and reference architectures for enterprise and cloud customers.
NVIDIA’s ability to integrate networking tightly with its GPU and software platforms gives it a unique advantage. Last year, the company introduced Spectrum-XGS, a next-generation version aimed at connecting multiple AI factories, showing its ambition to dominate large-scale networking for AI. If Spectrum-X adoption accelerates, networking could become one of NVDA’s most powerful revenue drivers in the AI infrastructure boom.
The Zacks Consensus Estimate for NVIDIA’s networking revenues in fiscal 2026 is pegged at $29.34 billion, indicating 125% growth from fiscal 2025’s $12.99 billion.
How Rivals Fare Against NVIDIA in AI Networking Space
NVIDIA faces competition from Broadcom (AVGO - Free Report) and Arista Networks (ANET - Free Report) in the AI networking space.
Broadcom is a leader in Ethernet switching and custom silicon solutions, providing high-performance chips that form the backbone of modern data centers. Broadcom’s strong relationships with hyperscalers like Google and Amazon allow it to deliver networking hardware tailored for large-scale AI and cloud workloads.
Arista Networks is another important rival, specializing in high-speed Ethernet switches used in AI and cloud environments. Arista Networks’ software-driven architecture and scalable systems make it a preferred choice for cloud service providers building AI clusters.
