JPMorgan's Jamie Dimon says Wall Street clients are 'gung ho' as the bank expects higher expenses

JPMorgan expects second-quarter investment banking revenue to rise 10% and trading revenue 11% year over year, while 2026 expenses are now projected about $1B above last month's $105B forecast, implying closer to $106B. Dimon said fees are running ahead of expectations and left open a potential $10B-$20B acquisition over the next couple of years. The article also notes strong industry activity from deregulation and AI infrastructure spending, with JPMorgan and peers set to benefit from the upcoming SpaceX IPO fees.

Analysis

The immediate signal is not just higher near-term revenue, but a broader reacceleration in the capital-markets operating leverage of the large universal banks. When trading and IB both inflect at the same time, expense growth becomes the key battleground: incremental comp and tech spend should stay sticky even if the revenue beat is cyclical, which means consensus may understate how much of the upside is being recycled into the cost base over the next 2-3 quarters. That dynamic favors banks with the best scale and cross-sell, but it also reduces the probability that the sector’s earnings revisions become purely “one-off” upside.

The second-order winner is likely not the same bank that prints the best headline quarter. JPM and BAC should capture the most visible flow because they have the balance-sheet capacity and brand to monetize the highest-quality mandates, but the real earnings beta may land in fee-sensitive peer groups with less diversified revenue mixes. If the current IPO/deal cycle persists, the next leg of relative outperformance could come from exchanges, prime brokerage, and market infrastructure providers rather than the lenders themselves, since activity increases tend to lift those businesses with lower compensation drag and less credit risk.

The main risk is that this looks late-cycle: managements are openly signaling exuberance while also flagging inflation and expensive assets. That combination usually means the market is paying up for peak margins just as wage inflation and regulatory/political noise can compress 2026 earnings estimates. Over a 6-12 month horizon, the key reversal trigger is either a softer rate-cut path that cools issuance volumes or an abrupt risk-off event that shuts the IPO window; in either case, revenue estimates would be cut faster than expense plans.

The contrarian takeaway is that the market may be too focused on the headline revenue beat and not enough on operating leverage leakage. If this is the start of a durable fee cycle, the best trade is not simply long the banks — it is long the best execution franchises and short the higher-fixed-cost laggards. For JPM specifically, elevated expectations plus a rich valuation make the stock more vulnerable to any disappointment in expense discipline than to a modest miss in trading activity.

Key Decisions for Investors

• Long JPM vs short C for the next 1-3 months: JPM should monetize the current capital-markets wave better, while Citi has less clean operating leverage and more sensitivity to any slowdown in fee momentum. Target 5-8% relative outperformance if the quarter confirms strong activity.
• Buy BAC on pullbacks over the next 2-6 weeks as a delayed beneficiary of the same trading/IB upcycle, but size smaller than JPM: BAC has more room for estimate revisions if deal flow broadens, with better upside if management guides 2026 expense growth below consensus.
• Pair long MS / short regional-bank ETF KRE over 3-6 months: the current backdrop favors fee-generating, market-facing franchises over lenders with more deposit and credit sensitivity. Risk/reward skews 2:1 if trading/IB remains firm.
• Use JPM upside via call spreads rather than stock for earnings-season exposure: buy 3-6 month call spreads to capture a beat while limiting downside if the market pivots to concern about 2026 cost inflation. Favor strikes just above spot to reduce premium bleed.
• Set a tactical short trigger on XLF if the sector re-rates on the first print but expense guidance moves up again: the trade works only if revenue acceleration outpaces comp inflation; otherwise, financials can fade quickly on margin compression.
