Big Three Banks Capture 80% of US Stock Trading Revenue Surge

Goldman Sachs, JPMorgan and Morgan Stanley have generated a combined $52 billion in equity trading revenue this year, cornering roughly 80% of the market tied to the AI-driven rally in US stocks. The gains stem heavily from margin lending extended to hedge funds positioning around AI-exposed names.

This concentration highlights how deeply leveraged positioning has become embedded in the current equity advance. As banks extend more credit against AI-related holdings, the sector's fortunes become increasingly tied to financing conditions rather than fundamentals alone.

Meanwhile, external pressures are building: an energy squeeze tied to surging tanker rates and oil prices nearing prior crisis highs adds another variable. Rising input costs could eventually pressure margins across the same US equities currently fueling bank trading desks' record revenue.
