September 16, 2026, (Inside AI) — Bank of America CEO Brian Moynihan delivered a blunt warning at the Barclays Financial Services Conference in New York on September 14: industrywide investment banking fees will drop roughly 10% in the third quarter compared with a year earlier. His own firm, he said, will fare even worse. Bank of America shares closed nearly 5% lower that day.
The prediction lands awkwardly in a market gripped by artificial intelligence enthusiasm. Equity indexes sit near records, and AI-linked companies dominate headlines. Yet the fee pool that sustains Wall Street's deal machine is narrowing, not widening. The recovery many investors expected is arriving, but only for a select group of firms.
The numbers explain why. In the second quarter, buyout-driven deal volume fell 37% from a year earlier, according to PitchBook. Private equity once generated steady fees for banks of all sizes because relationships mattered more than sector expertise. Those deals also leaned on debt financing, letting large balance-sheet lenders compete. That engine has stalled.
What remains is a market tilted toward fewer but larger transactions. Dollar volume holds up even as deal counts shrink. The result is a more exclusive fee pool. JPMorgan, Goldman Sachs, and Morgan Stanley captured nearly a quarter of global investment banking fees in the third quarter through September 15, according to LSEG data. That is up from 19% for the full quarter last year.

Investors have already priced in this divergence. Goldman Sachs shares have surged on expectations of a deal rebound. Wells Fargo, with a smaller advisory franchise, has lagged. Moynihan's comments suggest the rebound is not spreading as broadly as the market assumed.
AI Deals Mint A New Elite
The concentration has a clear driver: artificial intelligence. The largest AI companies now command the largest capital markets events, and only a handful of banks have the relationships to lead them. After steering SpaceX's $75 billion initial public offering, Morgan Stanley and Goldman Sachs are positioned to lead an Anthropic listing, according to sources familiar with the matter. Inside AI could not independently verify the reported mandate.
That dynamic creates a feedback loop. Winning one landmark AI listing builds credibility for the next. Boutiques and regional banks rarely get invited. Even large universal banks without top-tier technology coverage find themselves on the outside.
Morgan Stanley Co-President Dan Simkowitz, speaking at the same conference, offered a contrasting view.
"We have plenty to work on," Simkowitz said.
His optimism reflects the view from the top of the fee table. For firms outside that group, the picture is less encouraging. The gap between Wall Street's leading advisers and everyone else is widening, and the AI boom is accelerating the split rather than closing it.
Regulatory risk adds another variable. Rising safety concerns around advanced AI systems could trigger voluntary slowdowns or new rules. Either outcome would restrict the pipeline of AI-related offerings that currently sustains the top tier. A policy-driven pause would hit hardest at firms that have staked their recovery on technology mandates.

Private equity's slump compounds the problem. Buyout firms once spread fees across the Street. Now they are doing fewer deals, and the deals they do close are larger and more concentrated among elite advisers. Banks that relied on mid-market buyout work face a structural shortfall, not a cyclical dip.
The third quarter will test whether Moynihan's warning holds. If it does, the industry's AI-fueled party will look less like a broad recovery and more like a private gathering. The velvet rope, as one observer put it, is getting harder to clear.
For now, the market's attention remains fixed on the next blockbuster listing. Whether that enthusiasm translates into fees for anyone beyond a handful of firms is the question Wall Street will spend the coming quarters answering.
