AI infrastructure ahead of plan and growing
Cisco reported more than $800 million in AI infrastructure orders from webscale customers in the fourth quarter, bringing the total for 2025 to more than $2 billion, which is over 2x what the company originally projected. This is a mix of its own Nexus switches, optics, AI PODs, UCS servers and Silicon One.
Success here is critical for Cisco, as at one time, the company had next to no business with the hyperscalers. The development of Silicon One was pivotal in Cisco’s success with this audience, as it’s given them market leading price performance. Cisco has also cultivated a partnership with Nvidia and is the only company to have its silicon integrated into the GPU maker’s Spectrum-X product.
There is another wave of business coming for Cisco in this area selling AI infrastructure to non-hyperscalers. Robbins talked about this: “The Cisco Secure AI Factory with Nvidia provides a blueprint for building AI-ready data centers for enterprises, sovereign cloud providers and newly emerging neocloud providers. We expect the sovereign AI opportunity to build momentum in the second half of fiscal year ’26.”
AI will drive campus upgrades
Most of the focus of network growth in AI has been in the data center, as that’s where the growth has been. However, the traffic agentic AI creates will drive campus upgrades as well. On the call, Cisco showed a chart of traffic generated by chatbots pre and post agentic, and it shows Cisco is expecting agentic to drive a consistent level of traffic that most networks are not able to handle. Robbin explained: “Network traffic will not only increase beyond the peaks of current chatbot interaction but will remain consistently high with agents in constant interaction.”
The impact of this is twofold. The bump in traffic will drive the need for a higher performing wired and wireless network. Also, and maybe more importantly, as the AI agents gain autonomous decision-making and action-taking capabilities, pervasive security will be critical to ensure they operate reliably and safely. Cisco recently introduced its Smart Switches, which have integrated security and should see a multi-year refresh cycle coming. Given campus is Cisco’s largest business unit, a major refresh here can lead the company into sustainable, accelerated growth.
The platform effect is taking hold
One of the underappreciated aspects of Cisco’s turnaround has been the company returning to its roots and becoming product led. This has been and continues to be the mission for the company’s newly appointed Chief Product Officer, Jeetu Patel.
