Cisco Systems (CSCO) climbed 25% in the past week as investors woke up to a simple shift. AI is driving a multibillion-dollar rebuild of the networks that power modern computing, and Cisco sits squarely in that spend cycle.
That shift could ripple across the broader tech industry. As AI workloads become larger and more distributed, companies may need to upgrade switching, wireless, routing, optics, and data center infrastructure all at once to handle the surge in traffic and low-latency computing demands tied to inferencing and agentic AI applications.
Cisco sharply raises AI infrastructure outlook
Cisco’s AI infrastructure moved materially higher after management said on its fiscal third-quarter report that FY2026 hyperscaler AI orders should reach about $9 billion, up from its prior target of more than $5 billion. This is an 80% jump in guidance. Cisco generated $1.9 billion of hyperscaler AI orders during the period, bringing year-to-date AI orders to $5.3 billion.
CEO Chuck Robbins expects this is just the beginning. In the company’s Q3 earnings call reported on May 13, “Research conducted recently with around 3,500 technology leaders across global enterprises confirms increased urgency to modernize campus and branch networks. With traffic across these networks expected to increase 3x over the next 3 years because of AI, 93% of respondents are acceleratingtheir network modernization plans. These findings support our belief that we are still at the start of a multiyear, multibillion-dollar campus refresh opportunity.”
Cisco’s CEO also noted, “We believe the AI infrastructure opportunity in enterprise is continuing to ramp as Nexus switch orders tagged for AI deployments were up almost 50% sequentially in Q3.”

The more important detail is that expected revenue still trails far behind those bookings. Cisco said it expects to recognize roughly $4 billion of hyperscaler AI revenue in fiscal 2026, creating a much larger backlog than investors were modeling only a quarter ago.
Management said the higher forecast reflects real hyperscaler demand rather than channel loading or speculative ordering. That creates a longer revenue runway, while also increasing pressure on Cisco to execute operationally as those systems move toward shipment and installation.
Cisco’s order strength is spreading beyond hyperscalers
Cisco’s demand is broadening across the business. Total product orders rose 35% year over year, and product orders excluding hyperscaler AI still climbed 19%.
Management pointed to strength across campus infrastructure, switching, and WiFi 7 deployments as enterprises restart refresh cycles that had been delayed during the broader IT slowdown. The rebound also supports the idea that enterprise networking budgets are improving more broadly.
Cisco now has exposure to one of the largest AI infrastructure buildouts in years, while its legacy networking business is improving at the same time. A stock driven by hyperscaler capex alone carries sharp reversal risk when that customer group pauses. Cisco’s 19% growth in product orders excluding hyperscaler AI gives investors a more diversified demand base.
AI growth is squeezing Cisco’s margins
Cisco’s quarter also made clear where the pressure sits. Non-GAAP gross margin fell to 66.0%, down 260 basis points from a year earlier, while product gross margin dropped to 64.3%, down 330 basis points.
Management tied that decline primarily to the revenue mix. Faster-growing AI infrastructure systems, including optics, memory, and hardware-heavy configurations, carry higher costs than Cisco’s traditional networking and software products, which creates pressure as AI becomes a larger percentage of sales.
Management argued the pressure is being driven more by revenue mix and component costs than pricing weakness. That distinction matters because supply chain costs can normalize over time.
The next several quarters will likely determine whether Cisco can scale AI revenue while keeping margins relatively stable.
What could keep Cisco’s rally going
- AI backlog continues growing faster than recognized revenue, extending Cisco’s visibility into FY2027 and beyond.
- Enterprise networking demand strengthens alongside AI deployments, supporting a broader recovery across switching, campus, and wireless.
- WiFi 7 and campus refresh cycles accelerate hardware upgrades, reinforcing Cisco’s core networking franchise.
- Hyperscaler AI wins deepen Cisco’s role in next-generation data center infrastructure and improve long-term platform relevance.
- AI backlog converts into revenue without major margin deterioration, allowing growth to translate into stronger earnings power.
What could pressure Cisco stock
- AI systems become a larger percentage of revenue mix, keeping pressure on gross margin despite strong sales growth.
- Higher optics and memory costs weigh on profitability during the AI infrastructure ramp.
- Revenue recognition lags expectations if hyperscaler deployments or installations move slower than planned.
- Enterprise refresh demand fades after the initial recovery wave, weakening support from Cisco’s core business.
- Investors lose confidence in the rerating if revenue growth fails to drive meaningful EPS expansion.
Key takeaways for Cisco
Cisco’s story now centers on a much larger AI order base that extends revenue visibility well past the current fiscal year. The raised hyperscaler outlook points to a backlog the market had not fully priced in, and that has shifted the thesis toward execution and conversion. The strength also extends beyond AI. Enterprise, campus, switching, and wireless are all contributing to a broader recovery across the business.
Margins remain the pressure point. AI systems carry a lower profitability profile than Cisco’s legacy mix and put more weight on optics and memory costs. The stock can keep working if backlog conversion and core recovery outpace that margin dilution. If margins keep sliding, the rerating will outrun the earnings power behind it.
