Wall Street is having a moment, and Citigroup is making the most of it. The bank reported total markets revenue of $5.9B in the second quarter of 2025, a 16% jump from the same period last year, marking its strongest second quarter since 2020.

Net income came in at $4.0B on total revenues of $21.7B, clearing analyst estimates by enough to matter.

Where the money came from

Fixed Income Markets carried the heaviest load, generating $4.3B, up 20% year-over-year.

Equity Markets contributed $1.6B, a 6% increase from a year ago. The more interesting number buried inside that figure: prime balances grew roughly 27%, pointing to a surge in institutional client activity.
