Goldman Sachs Group IncGoldman Sachs contributed the largest rise of $7.1 billion after advising on SpaceX's IPO and Alphabet's equity raise.
Wall Street's five largest banks posted a record $114 billion in capital markets revenue in the first half of 2026, up 31.5% from a year earlier, driven by stock trading, dealmaking, and financing tied to the AI boom. Stock trading accounted for more than half of the increase, with Goldman Sachs contributing the largest rise of $7.1 billion after advising on SpaceX's IPO and Alphabet's equity raise. Wells Fargo analyst Mike Mayo called AI the 'No. 1 earnings driver' for big banks this year, comparing capital demands to a '100-foot wave' lifting Wall Street. Morgan Stanley estimates the broader AI build-out will amount to $10 trillion in spending over multiple years, with the cycle only 10% to 15% complete according to CEO Ted Pick. Executives cautioned that the momentum could face bumps, with JPMorgan CFO Jeremy Barnum noting it is 'a little bit hard to imagine' repeating the record trading haul.
