JPMorgan Chase CEO Jamie Dimon said Tuesday that while artificial intelligence tools could eventually help companies defend themselves from cyberattacks, they are first making them more vulnerable.

Dimon said that JPMorgan was testing Anthropic's latest model — the Mythos preview announced by the AI firm last week — as part of its broader effort to reap the benefits of AI while protecting against bad actors wielding the same technology.

"AI's made it worse, it's made it harder," Dimon told analysts on the bank's earnings call Tuesday morning. "It does create additional vulnerabilities, and maybe down the road, better ways to strengthen yourself too."

When asked by a reporter about Mythos, Dimon seemed to refer to Anthropic's warning that the model had already found thousands of vulnerabilities in corporate software.

"I think you read exactly what is it," Dimon said. "It shows a lot more vulnerabilities need to be fixed."

The remarks reveal how artificial intelligence, a technology welcomed by corporations as a productivity boon, has also morphed into a serious threat by giving bad actors new ways to hack into technology systems. Last week, Treasury Secretary Scott Bessent summoned bank CEOs to a meeting to discuss the risks posed by Mythos.

JPMorgan, the world's largest bank by market cap, has for years invested heavily to stay ahead of threats, with dedicated teams and constant coordination with government agencies, Dimon said.

"We spend a lot of money. We've got top experts. We're in constant contact with the government," he said. "It's a full-time job, and we're doing it all the time."
