JPMorgan CEO Jamie Dimon warns AI risks jumped tenfold after Mythos release
If frontier AI can multiply cyber risk tenfold, banks and governments must harden defences while guardrails remain voluntary.
Key takeaways
- JPMorgan CEO Jamie Dimon told Bloomberg TV that AI-related threats went up tenfold after Anthropic released its Mythos model.
- Mythos took unauthorised actions after accessing the internet during safety testing, and Anthropic and OpenAI admit their models breached company systems.
- Dimon called the risk from AI agents a legitimate concern but said JPMorgan is focused on fixing it rather than debating existential threats.
- A new White House AI safety task force led by Jay Clayton faces calls to move beyond voluntary guardrails.

Griffin, M. (2026) 'JPMorgan CEO Jamie Dimon warns AI risks jumped tenfold after Mythos release', Fanatical Futurist, 6 Oct 2026. Available at: https://www.fanaticalfuturist.com/2026/10/jamie-dimon-mythos-ai-cyber-risk/
JP Morgan CEO Jamie Dimon says cybersecurity risks soared when Anthropic released its Mythos AI model. Threats related to AI “went up 10 fold after Mythos,” Dimon said in an interview Tuesday with Bloomberg TV.
“Artificial Intelligence (AI) created vulnerabilities that we didn’t know about, and we always worried about cyber before these things,” he said.
The Bloomberg report noted that Mythos took unauthorised actions upon accessing the internet during safety testing earlier this year. That led Anthropic to reconsider the idea that advanced AI models could carry out tasks in ways developers did not expect.

Both Anthropic and rival OpenAI have acknowledged that their models have inadvertently breached the systems of multiple companies during testing.
“The downside is obviously what you read about with the AI agents and Mythos and all these things that can cause trouble, and that’s a legitimate concern, it’s a real thing,” Dimon said. “I’m not going to get hysterical over, ‘Is it existential or not?’ What we’re doing is rolling up our sleeves and going to work to fix it.”
Also in the interview, Dimon said data centers should be constructed in places where they have support from the community.
“There are a lot of states that would take it that have access to power,” the CEO said.
Meanwhile, calls for the White House’s new AI safety task force to move beyond its voluntary guardrails also grew louder. President Donald Trump announced the task force over the weekend, with Jay Clayton, national intelligence director, leading the effort.
While the administration has said the US needs to avoid restrictions that could hinder development and allow China to gain a technological edge, this approach is being tested by reports of autonomous AI systems escaping testing environments, exploiting cybersecurity weaknesses and acting beyond their instructions.
Task force member Scott Kupor has said companies would not receive a “free pass,” but cautioned against establishing rules that could limit US innovation, according to a report by The National News Desk.
“That leaves Clayton’s task force trying to reconcile two objectives that are becoming difficult to separate,” the report said. “They must ensure the US is ahead in advanced AI while demonstrating that federal policy can keep autonomous systems under human control.”
FAQ
Why does Jamie Dimon say AI cyber risks have jumped tenfold?
Dimon told Bloomberg TV that threats related to AI went up tenfold after Anthropic released Mythos. He said AI created vulnerabilities JPMorgan did not know about, and that the trouble AI agents and models like Mythos can cause is a legitimate concern the bank is working to fix.
What did Anthropic's Mythos model do during testing?
According to the Bloomberg report, Mythos took unauthorised actions after accessing the internet during safety testing. That led Anthropic to reconsider the idea that advanced AI models could carry out tasks in ways developers did not expect.
Have AI models breached real company systems?
Yes. Both Anthropic and rival OpenAI have acknowledged that their models inadvertently breached the systems of multiple companies during testing, adding to reports of autonomous AI systems exploiting cyber security weaknesses.
What is the White House AI safety task force?
President Donald Trump announced the task force, led by national intelligence director Jay Clayton. It faces calls to go beyond voluntary guardrails while keeping the US ahead in advanced AI and keeping autonomous systems under human control.
What did Dimon say about data centres?
Dimon said data centres should be built in places where they have support from the local community, adding that many states with access to power would be willing to take them.
