Cisco’s Silicon One Chip Fuels AI Gold Rush: $2.1 Billion in Orders Spark Historic Stock Week

Cisco surged 24% on record AI orders of $2.1B and strong earnings, but valuation at 37x earnings and cash flow decline signal caution.

Behind Cisco Systems Inc.’s record-breaking week on Wall Street lies a quiet revolution in data centre architecture. The company’s proprietary Silicon One chip, paired with advanced optical systems, is powering a transition to 800-gigabit and 1.6-terabit networks – speeds essential for training the largest large language models. That shift has unleashed a torrent of demand from hyperscale cloud providers, with Cisco booking $2.1 billion in AI-infrastructure orders in its fiscal third quarter alone, matching the entire prior fiscal year’s total.

The financial results that accompanied the hardware surge stunned the market. Revenue climbed 12% year over year to $15.84 billion, beating analyst expectations, while adjusted earnings per share of $1.06 also came in ahead of consensus. The core networking business was the standout: revenue from network solutions rose 25%, and orders in that division jumped by more than 50%. Chief Executive Chuck Robbins described the moment as the “start of a networking supercycle,” as big cloud operators race to prevent data bottlenecks in massive AI clusters.

That narrative has drawn a stampede of analyst upgrades. At least six major investment banks raised their price targets within days. HSBC’s Stephen Bersey lifted his to $137, citing a rapidly growing AI revenue contribution, while Evercore set a bull-case target of $150. The optimism triggered the best week for Cisco shares in nearly 25 years. The stock closed Friday at €101.64, a fresh 52-week high, after surging 24% over seven sessions. Year to date, the gain stands at roughly 56%.

Underneath the top-line strength, some cash-flow metrics showed strain. Free cash flow fell 12% from a year earlier to around $3.3 billion, though the company’s margin remained healthy at just over 21%. Separate data showed that operating cash flow slipped 7%. Management is betting that the integration of recently acquired security software firm Splunk will bolster recurring revenue and eventually ease pressure on cash generation.

The company is also rewarding shareholders directly. Cisco’s board declared a quarterly dividend of $0.42 per share, payable on July 22, 2026. Institutional investors have taken notice: May Hill Capital nearly doubled its Cisco position in the latest reporting period.

Yet the rally has pushed valuation into territory that demands caution. The stock now trades at 37 times trailing earnings, a multiple that already prices in significant future growth. Insider selling has been notable in recent months, and the broader macroeconomic environment – stubborn U.S. inflation delaying hopes for rate cuts – could weigh on high-multiple tech names. Technically, the shares sit 55% above their 200-day moving average, a level that historically invites profit-taking. The relative strength index reads 65, just below the overbought threshold, suggesting upward momentum is intact but stretched.

Looking ahead, Cisco guided for fiscal fourth-quarter revenue of up to $16.9 billion, with earnings per share expected to land at the high end of its internal range. Robbins has begun reallocating capital and engineering resources aggressively toward silicon, optics and cybersecurity, betting the supercycle will sustain demand as hyperscalers upgrade their networks for the AI era.
