Citadel Securities posts record $7.3B Q2 trading revenue

Citadel Securities reported $7.3 billion in trading revenue for the second quarter, and net income rose to $3.3 billion, an increase of more than 250% from a year earlier. An unnamed person familiar with the results provided the figures.

The Miami-based electronic market maker, founded by Ken Griffin, declined to comment.

The gains came during a period of heightened market volatility in the second quarter that increased trading volumes and spreads for major quantitative trading firms.

Other large market makers also posted strong results. Hudson River Trading generated $11.4 billion in trading revenue in the second quarter, more than four times its amount from the same period a year earlier. Jane Street reported more than $40 billion in net trading revenue by mid-August despite an estimated $15 billion loss in July; that mid-August total exceeded the firm’s full-year 2025 revenue of $39.6 billion. Firms including Susquehanna International Group reported robust trading performance over the period.

Electronic market makers provide liquidity to markets, capture the difference between buy and sell prices, and execute large numbers of trades automatically using computer systems. Volatile conditions tend to raise trading activity and price movement, which can increase opportunities for firms that trade at high frequency and in large size.

The reported results reflect higher trading revenue and improved profitability in the second quarter compared with the prior year, based on the figures provided.
