Key Takeaways
  • • The five largest US investment banks earned about $67bn in equities trading revenue through September, roughly $7bn more than last year's record, according to the primary source's publisher summary.
  • • Goldman Sachs, JPMorgan and Morgan Stanley together accounted for $52bn of that total, with Goldman Sachs leading on more than $19bn.
  • • Looser leverage rules have allowed the banks to finance hedge fund activity, per the source, which ties prime brokerage lending to the sector's trading gains.
  • • The available source text is limited to a publisher summary, so the link between bank financing and hedge funds' AI-related strategies is not fully documented here.
Summary
The five largest US investment banks had already surpassed last year's record equities trading revenue by about $7bn through September, generating a combined $67bn, according to the publisher summary of the primary source. Goldman Sachs, JPMorgan and Morgan Stanley accounted for $52bn of that figure, with Goldman Sachs leading at more than $19bn.

The source attributes part of this performance to looser leverage rules, which have allowed the banks to finance a larger volume of hedge fund activity. The publisher summary frames this financing as a driver of the banks' equities franchises, as hedge funds increase their use of prime brokerage services.

The headline points to the role of these banks in supporting hedge funds' investments in artificial intelligence. The available text does not provide further detail on specific AI-focused strategies, fund sizes or individual deals, so those claims cannot be verified from the source material provided.

Readers should treat the figures above as reported through September of the current year, as stated in the source, and consult the full article for additional detail on the financing arrangements and the funds involved.
