What happened
Citadel Securities, the market-making arm separate from Ken Griffin's Citadel hedge fund, generated $7. 3 billion in net trading revenue in the second quarter, according to figures reported by Crypto Briefing on Wednesday. It's the highest quarterly print the firm has ever posted and, on a run-rate basis, would put 2026 revenue north of the $23 billion the firm booked in 2022, its previous banner year.
The company doesn't file public quarterly financials the way a listed bank does, so the figure surfaces through counterparty disclosures and reporting rather than an SEC filing. Griffin has spent the last decade turning Citadel Securities into the pipe that most retail brokerages route through. On a typical US trading day, the firm executes roughly a quarter of all listed equity volume and a larger share of retail options flow.
The Q2 print says that pipe carried a lot more water than usual.
Why it matters
For crypto readers the direct read is narrow. Citadel Securities is not a spot bitcoin exchange and Griffin spent years publicly skeptical of the asset class. The indirect read is bigger.
The firm is one of the authorized participants on multiple spot bitcoin and ether ETFs, meaning it creates and redeems shares that underpin the roughly $130 billion in US spot crypto ETF assets. It's also a liquidity provider on EDX Markets, the institutional crypto venue backed by Fidelity, Schwab, and Citadel Securities itself. A record quarter for the market maker means the same balance sheet that quotes IBIT and FBTC is fatter, faster, and more confident going into the second half.
