JPMorgan Chase said on its October 13, 2026, third-quarter earnings call that it is blocking outside AI agents from directly accessing customer accounts, while developing internal agentic AI tools. CEO Jamie Dimon cited risks from rogue or hijacked software, unauthorized actions and unclear liability if an agent moves money improperly. CFO Jeremy Barnum said the bank is working to prevent unauthorized access to customer information and is blocking third-party access to the extent it can. The concerns include credential sharing and screen scraping, in which an outside service logs in with a customer’s username and password to retrieve account data. JPMorgan has historically resisted that practice, and the rise of agents that can take actions rather than simply read balances increases the potential exposure. The bank also restricted Hong Kong staff access to Anthropic’s Claude in June 2026 over licensing and compliance issues. JPMorgan provided preliminary 2027 net interest income guidance of $107 billion excluding Markets, about $5 billion above annualized fourth-quarter 2026 guidance, with roughly 25% of the increase tied to the yield curve and the remainder mainly to balance-sheet growth and deposit and loan mix changes. It is piloting Smart Cash, an internal tool designed to forecast cash flow and move funds to maximize yield. Third-quarter net income was $15.3 billion, up 6% year over year, while fixed-income markets revenue fell 4% to $5.4 billion. Adjusted earnings were reported at $5.75 per share, while an earlier earnings figure was $5.57, against a $5.90 analyst consensus; managed revenue rose 8% to $50.91 billion, below expectations of $51.26 billion. JPMorgan reaffirmed a 17% through-the-cycle ROTCE target. The bank’s policy leaves open questions about how effective the block is, who bears losses caused by outside agents and whether JPMorgan’s internal tools will provide a compelling alternative.
