JPMorgan's Dimon warns of tenfold rise in cyber risk from AI

Investing.com -- Cyber threats just got a lot scarier for the world's biggest banks. JPMorgan Chase CEO Jamie Dimon warned Tuesday that the release of Anthropic's powerful Mythos AI system has exponentially escalated the financial sector's cybersecurity vulnerabilities, cementing cyberattacks as the bank's absolute biggest threat.

Speaking with Bloomberg TV's Tom Mackenzie at the 14th annual JPMorgan Tech Summit in London, Dimon didn't mince words the mounting dangers of advanced AI agents.

"I published my chairman's letter... I said cyber is our biggest risk," Dimon stated. "And they didn't publish Mythos yet. I would say that went up tenfold after Mythos."

While Dimon acknowledged the immense potential for AI to "cure a lot of diseases," prevent traffic accidents, and revolutionize materials science, he stressed that the technology has also handed bad actors unprecedented leverage.

"AI created vulnerabilities that we didn't know , and we always worried cyber before these things," Dimon explained. "The downside is obviously what you read with the agents and Mythos and all these things that can cause trouble. And that's a legitimate concern. It's a real thing."

However, the Wall Street veteran noted he isn't getting "hysterical" over whether AI poses an existential threat, adding, "What we're doing is rolling up our sleeves and going to work to fix it." Part of that fix involves the newly formed Alliance for Critical Infrastructure, a 50-company coalition spanning six vital industries—including tech, finance, water, and transport—designed to fortify defenses against systemic threats.

Unchecked Debt and "Free" Policy

Beyond the digital frontier, Dimon sounded the alarm on ballooning sovereign debt, pointing to recent bond selloffs as a stark indicator of what happens when borrowing goes unchecked.

"It's a warning to governments, okay: we can't borrow endlessly and spend endlessly," Dimon cautioned. Noting that U.S. government debt has surged from 50% to 100% of GDP, he warned that "there will be a point where the market will ask for more and more," inevitably driving up corporate credit spreads and squeezing private markets.

Dimon also pushed back against the idea that boosting economic output requires massive fiscal expansion.

"This may be my op-ed: Good policy is free," Dimon remarked. "Good policy in the United States and in Europe can drive growth 1% higher, and it does not cost money." He pointed to sensible improvements in permitting, education, deregulation, climate policy, and immigration as deflationary catalysts that could naturally drive down debt-to-GDP ratios.

The AI Infrastructure Boom

Addressing the massive capital expenditures projected for global AI infrastructure, Dimon pushed back on the politics of building massive data centers, half of which are currently slated for Texas and Virginia.

His advice to tech founders facing local resistance was blunt: go where you are welcomed.

"You build them where they're wanted... people don't want them there, you're not going to win. You get lawsuits," Dimon said. "But there are a lot of states [that] would take it that have access to power. And of course, any big company has to be a good community citizen."

Despite a "little bit of a slowdown in September" for U.S. investment banking pipelines, Dimon remains largely optimistic the broader tech ecosystem, noting that the London summit has grown from 20 attendees to thousands of global investors. "A lot of these companies, they're real. They're going to invent things that help mankind for hundreds of years," he said.
