Silicon Valley legend John Chambers, the former CEO of Cisco Systems Inc., is doubling down on artificial intelligence (AI), predicting it will accelerate even faster in 2026 despite growing concerns about a potential bubble.
“I bet on this over eight years ago,” Chambers said in a 30-minute interview, noting that mainstream interest only materialized after Microsoft Corp.’s significant investment in OpenAI. “We are still in the early innings” of its explosive trajectory.
Chambers pointed to data center and AI infrastructure spending as evidence of sustained growth, acknowledging that while “there will be spectacular train wrecks,” some of the largest companies across all sectors — from Ford Motor Co. to Walmart Inc. — are committed to significant AI investments over the next five to 10 years.
Unlike the internet boom, which was at the mercy of bandwidth infrastructure, Chambers argues that today’s AI revolution is backed by players with deep pockets, several of whom are spending tens of billions of dollars this year on AI. He is particularly bullish on NVIDIA Corp., predicting the company will continue generating tremendous profits from AI. (Indeed, global IT spending is expected to reach $4.25 trillion this year, its strongest annual performance since 1996, because of AI infrastructure investments, according to IDC.)
AI agents — whose steep ascent has been predicted all year — are gaining traction, expanding from call centers to personal assistants. However, Chambers warns of a “huge divergence between winners and losers,” predicting potential fallouts among one or two of the Magnificent Seven tech companies in 2026 — a development that could significantly impact the broader economy. He’s most optimistic about Microsoft, NVIDIA, and Google, noting how Google rapidly reinvented itself in 2025 after Microsoft initially outmaneuvered them, catching the software giant flat-footed.
“If Google can make a dramatic comeback, it shows how one company’s fortunes can change so quickly — and vice versa — under this tremendously fast-moving AI technology,” he said in a video interview.
The speed of AI is also transforming startup timelines. Chambers predicts the time to an initial public offering (IPO) or acquisition will shrink dramatically, from the current 12-15 years to just 7-10 years. OpenAI and Anthropic are among the most aggressive AI startups eyeing an IPO in the next year or two.
On the cybersecurity front, Chambers sees growing challenges as AI expands in scope and broadens the potential attack surface within an enterprise. He highlighted one concerning trend: approximately 15% of company job video interviews now involve deepfakes, primarily originating from North Korea. His portfolio company Pindrop specializes in identifying deepfakes through voice and image verification, partnering with major platforms like Zoom Communications Inc., Microsoft, and Cisco.
Reflecting on Silicon Valley’s evolution, Chambers lamented the cultural shift from the collaborative days of Apple Inc. co-founder Steve Jobs, venture capital pioneer John Doerr, and Intel Corp.’s executive leadership. In the mid-1990s, he noted, 92% of Americans viewed technology positively — a figure that has plummeted to less than half today, underscoring the industry’s changing relationship with society, Chambers said.
