Jamie Dimon, CEO of JPMorgan Chase, stated that artificial intelligence tools, while potentially beneficial for cybersecurity in the long term, are currently increasing vulnerabilities for companies. During JPMorgan's earnings call on April 14, 2026, Dimon revealed that the bank was testing Anthropic's latest AI model, Mythos, which was previewed by the AI firm the previous week. Dimon referenced Anthropic's warning that Mythos had already identified thousands of vulnerabilities in corporate software, emphasizing that 'it shows a lot more vulnerabilities need to be fixed' [1].
Dimon explained that AI has made defending against cyberattacks more challenging, noting, 'AI's made it worse, it's made it harder. It does create additional vulnerabilities, and maybe down the road, better ways to strengthen yourself too.' He highlighted that JPMorgan invests heavily in cybersecurity, with dedicated teams and ongoing coordination with government agencies, but warned that risks extend beyond individual institutions due to the interconnected nature of the financial system [1].
JPMorgan CFO Jeremy Barnum echoed these concerns, stating that the industry has long recognized AI as a double-edged sword in cybersecurity. Barnum noted that while AI tools can help identify vulnerabilities, they can also be used by malicious actors to launch attacks. He said that recent advances from Anthropic and others have intensified this trend [1].
Dimon also stressed the continued importance of basic cybersecurity practices, such as data protection and network hygiene, as essential defenses despite the rise of advanced AI tools. Additionally, Goldman Sachs CEO David Solomon confirmed that his bank was also testing Mythos, though he did not provide further details [1]. Last week, Treasury Secretary Scott Bessen convened a meeting with bank CEOs to discuss the risks posed by Mythos [1].
CONCLUSION
Jamie Dimon's comments highlight growing concerns among major banks about the cybersecurity risks introduced by advanced AI models like Anthropic's Mythos. While AI offers potential long-term benefits, its current impact is to expose more vulnerabilities, prompting increased vigilance and investment in cybersecurity across the financial sector.
