Goldman, JPMorgan, Morgan Stanley capture 80% of AI-driven trading gains
The three largest Wall Street firms have generated $52 billion from stock trading this year, largely through increased leverage loans to hedge funds.

What This Means
The three banks have captured outsized share of capital-raising and M&A work tied to the AI sector boom. This reflects their scale in equity underwriting and institutional client relationships, which concentrate deal flow among top-tier firms during periods of concentrated investor demand. The concentration matters for banking revenue and for which firms shape corporate strategy in the fastest-growing technology segment.

How This Could Play Out
First assessed Oct 21 · Reviewed Oct 24, no change
Resolved
UNLIKELYEquity underwriting fees compress as AI deal flow normalizes and mid-tier banks gain share, reducing top-tier banking revenue.
Status quo
LIKELYConcentration of AI-linked capital raising and leverage lending among the three banks persists, sustaining elevated trading and advisory revenues for large-cap financials.
Worsens
POSSIBLELeverage loans to hedge funds backing AI trades unwind sharply if valuations crack, forcing rapid deleveraging and widening bid-ask spreads in equities as the three banks reduce risk exposure.
