Citadel Securities just posted $4.3 billion in trading revenue for the first quarter of 2026. That is not a typo, and it is not annualized. One quarter. $4.3 billion.
To put that in perspective, the firm’s Q1 2025 revenue was $3.4 billion, which itself was considered jaw-dropping at the time. The new number represents roughly a 26% jump in just twelve months.
The numbers behind the machine
Citadel Securities has been on a tear that makes its own previous records look quaint. Full-year 2025 trading revenue hit $12.2 billion, a 25% increase over the prior record of $9.7 billion set in 2024. The Q1 2025 quarter alone generated $3.4 billion in revenue and $1.7 billion in net income, meaning the firm was converting roughly half its top line into profit.
What’s notable is that the Q1 2026 performance wasn’t driven by a single lucky bet or one overheated asset class. The results reflect broad-based trading strength across the firm’s various desks.
