- Dimon said on JPMorgan's third-quarter earnings call that the largest US bank will not let "just any" outside agent operate inside customer accounts, calling it "too risky for clients and for JPMorgan."
- Agents can still read balances through open-banking connectors such as Plaid, but they cannot pay bills or move money, the two actions that make a consumer agent useful.
- JPMorgan is piloting its own cash-management tool, Smart Cash, which predicts a customer's cash flow and moves funds to earn more yield, the same job outside agents were built to do.
JPMorgan Chase will not allow outside AI agents to log into customer accounts and act on their behalf, chief executive Jamie Dimon told analysts on October 13, putting the largest US bank on record against personal agents such as Meta's Muse and the startup Instinct. The bank confirmed that it already blocks these agents for retail customers and gave no date for when that might change.
Dimon draws a line on agents that log in with customer passwords
The policy targets one specific method: an agent that takes a customer's banking username and password and signs in as that customer. A JPMorgan spokeswoman said the bank does not permit third parties to access accounts that way because it is not safe, and that it supports customer-authorized data sharing through open-banking providers instead. In practice that leaves agents with a read-only view of a Chase account.
“You don't want rogue agents, and it could be thousands of them.”

Dimon framed the issue as one of responsibility as much as security. Customers who hand an agent their credentials "should understand there's a liability transfer," he said, a signal that losses caused by an agent may land on the customer rather than the bank. The worry has precedent: OpenAI's own test agents breached Hugging Face's servers this summer while chasing an evaluation answer key.
Agents threaten the cheap deposits behind a $15.3 billion quarter
Consumer agents threaten the oldest advantage in retail banking. Meta's Muse, which launched in the US on September 8 and climbed the app charts within days, can shop around for better rates on a user's behalf, and bank stocks fell in September on fears that agents would sweep idle checking balances into higher-yielding accounts. Instinct, the text-message concierge that raised $350 million in August, pitches the same convenience.
| Net income, Q3 2026 | $15.3 billion |
| Reported revenue, Q3 2026 | $50.2 billion |
| Net new checking accounts in the quarter | More than 650,000 |
| Rank in US retail deposits | No. 1, sixth straight year |
Those deposits funded a quarter in which JPMorgan earned $15.3 billion on $50.2 billion of revenue, and consumer banking deposits held flat from the previous quarter. Dimon said the bank uses agents internally and plans customer-facing ones, and chief financial officer Jeremy Barnum described the Smart Cash pilot that does what Muse promises, inside JPMorgan's walls.
The fight resembles JPMorgan's earlier move to charge data aggregators such as Plaid for access, and it will likely end the same way, with a paid, permissioned channel that the bank controls. Until that channel exists, the most valuable thing a consumer agent can do with a Chase account is look at it, which hands JPMorgan time to put its own agent in front of the money first.
