Wall Street's Q2 blowout comes with a new AI cost doctrine from JPMorgan and BofA

On a $49 billion profit day, JPMorgan's CFO told staff to stop reaching for frontier models for routine work, Dimon counted nearly 1,000 AI use cases, and BofA's Moynihan pressed for tighter controls.

JPMorgan Chase posted a record $21.2 billion in Q2 net income on Tuesday, and used the same earnings cycle to tell its own employees to stop paying for frontier AI models to do things a cheaper model can handle. The doctrine landed alongside numbers that would ordinarily silence any cost conversation: $58.0 billion in managed revenue, $7.70 in reported EPS ($16.9 billion and $6.14 excluding significant items), an 86% year-over-year jump in Equity Markets to $6.0 billion, and investment banking fees up 30% to $3.3 billion, their highest level since 2021.

The message came from CFO Jeremy Barnum, who told staff that “you really don’t need the latest cutting edge incredibly expensive model to summarize an analyst report.” Barnum described current token spend as “not financially meaningful this year” and “a trivial number for the first half of the year,” per Bloomberg, while pushing a house prescription: right model for the right purpose, open source where it fits, and spend that returns value.

That the discipline is being installed now, before the bill matters, is the point. Full-year adjusted expense guidance was raised by $2.5 billion to roughly $107.5 billion, with management citing technology, branches, bankers, and AI tools.

CEO Jamie Dimon pushed the other direction on capability, counting nearly 1,000 AI use cases across the firm and calling it “huge efficiency in certain parts of the company.” His framing on adoption: “It’s kind of just starting.” His framing on the endpoint: “The ultimate beneficiary of AI will be our customers”.

Bank of America’s Brian Moynihan offered the risk-side counterweight, saying AI “has great utility. It has to be carefully managed. You have to have your data perfect. You have to have your rules base, so it doesn’t make mistakes.” Elsewhere on the tape, Block reiterated the February claim that AI was helping cut about 40% of its workforce, and SpaceX debuted at an $86 billion valuation.

Combined Q2 profits across JPMorgan, Goldman Sachs, Bank of America, Citigroup, and Wells Fargo hit $49 billion, up 39% year over year. Wells Fargo’s Mike Mayo called it a “tipping point,” naming Goldman, JPMorgan, and Morgan Stanley as the top three AI beneficiaries. The banks that spent the last cycle rehearsing AI narratives are now underwriting them, and quietly rationing them.
