Cisco has spent the last two years getting overshadowed by Nvidia, and on Thursday it stopped looking like a side character.
Shares jumped 15%, the biggest one-day move for the stock since 2011. The reason wasn't a new chip or a flashy product launch - it was math.
CEO Chuck Robbins told CNBC he sees a "networking supercycle" forming. In plain English: the data centers running AI need cables, switches, and optics, and they need them now.
So Cisco lifted its AI infrastructure order forecast from $5 billion to $9 billion for the fiscal year. That's not a tweak - it's nearly doubling the number on the books.
The company also said it would cut fewer than 4,000 jobs - less than 5% of its workforce. Robbins called it "a rapid reallocation of resources" and added that many of the affected employees would shift into the AI roles the company is now staffing up.

Until recently, Cisco was the slow kid in the AI trade - Nvidia and its chip peers got the spotlight, while Cisco's networking gear got treated like a utility play.
The story flipped this year as the stock recently broke through its dot-com-era highs, with investors finally pricing in a simple idea: you can't run a data center without the wires and switches connecting the chips.
Robbins admitted forward bookings are still hard to lock in, because hyperscalers - the Amazons, Microsofts, and Googles of the world - keep changing what they want. Cisco has even opted out of some projects with them.
What he gave investors instead was confidence about the size of design wins and customers' capital plans. The forecast is the signal.
Two things to keep an eye on. The first is the next round of hyperscaler capex updates - capex covers the dollars spent on buildings, servers, and chips - and if their AI spend keeps climbing, the $9 billion forecast probably isn't the last upgrade.
The second is the layoff math, with Robbins pointing the cut roles at silicon and optics. That bet either shows up in 2027 numbers or it doesn't.
Either way, the AI trade just got wider.
