Citadel Securities’ Second-Quarter Trading Revenue Slumps 8.4%

Citadel Securities reported a slump in second-quarter net trading revenue, but the firm still notched a record first half amid volatility caused by geopolitical tensions and the Trump administration’s tariff wars.

Net trading revenue declined 8.4% in the second quarter, to $2.39 billion, according to people familiar with the matter. But a booming first three months still generated an all-time high for the first half of $5.77 billion, the people said, asking not to be identified discussing non-public information.
