Dimon Puts A "No Rogue Agents" Sign On JPMorgan's Front Door 🚫🤖

JPMorgan Chase is barring outside AI agents from logging in to or acting on customer accounts, with CEO Jamie Dimon citing the threat of "rogue agents" as the reason behind the policy. Speaking during JPMorgan's third-quarter earnings call, Dimon said the bank would not open its systems to third-party agents because the risks to clients and to the bank itself are too high. "You don't want rogue agents," Dimon told analysts, framing the decision as a defensive move rather than an outright rejection of agentic technology.

The policy extends to any external software that would attempt to access accounts using a customer's banking credentials. JPMorgan does, however, continue to support customer-authorized data sharing through open banking providers. The scale of what is being protected is significant: the bank reported $15.3 billion in third-quarter net income and $5.1 trillion in total assets as of Sept. 30. A Cloud Security Alliance note previously documented a campaign that used three open-source AI agents to breach at least 27 organizations, a reference point cited as JPMorgan drew its line.

Some firms have taken the opposite approach. Germany's Scalable Capital opened its platform to ChatGPT, Claude, and Grok in August, allowing users to analyze portfolios and place trades through prompts, though each trade requires user approval and the assistants cannot make payments or withdraw money. Meta's Muse, launched in September, connects to financial accounts through Plaid and offers guidance on balances, transactions, and investment holdings. Retailers have started to push back: on September 20, Amazon began blocking Muse from its site, with shoppers now encountering pop-ups stating that the use violates Amazon's terms.

Meta is developing Poppy, a personal agent protocol built with Sierra that would tell companies when an agent is acting on behalf of a customer. Fortune reported that Meta declined to comment on whether Muse could continue offering financial help if more banks adopt JPMorgan-style restrictions. Dimon acknowledged that broader adoption of AI agents will increase risks for both banks and customers, adding that JPMorgan is building its own internal tools to protect clients as the technology spreads.
