Hudson River Trading posts $11.4B trading windfall amid market tumult
Hudson River Trading pulled in $11.4 billion in trading revenue during the second quarter of 2026, a single-quarter record. The New York-based quantitative market maker has turned market chaos into a cash machine, and Q2 was the loudest quarter yet.
To put that number in perspective: HRT’s full-year 2025 net trading revenue was approximately $12.3 billion. The firm nearly replicated an entire year’s haul in 90 days.
A first half for the record books
HRT’s first quarter of 2026 was already a breakout performance, with $6.4 billion in trading revenue representing a 135% year-over-year increase. That Q1 figure alone accounted for more than half of the firm’s total 2025 earnings.
First-quarter profits surged to roughly $4.2 billion, up approximately 175% from the prior year.
Combined, HRT’s first-half 2026 trading revenue sits at approximately $17.8 billion.
Why volatility is the house’s best friend
Market-making firms like HRT don’t bet on whether stocks go up or down. They sit in the middle of trades, providing liquidity to buyers and sellers, and pocket the difference between bid and ask prices. When markets are calm, the spread between those prices compresses, and revenue thins out. When volatility spikes, spreads widen and trading volumes surge.
HRT’s edge comes from proprietary quantitative strategies and a technology stack built to exploit exactly these conditions. The firm deploys algorithms across multiple asset classes, including equities and options, that can adjust to shifting volatility regimes faster than any human trader could blink.
The arms race at the top
HRT doesn’t operate in a vacuum. It competes directly with other titans of quantitative trading, most notably Jane Street and Citadel Securities.
Jane Street made headlines in 2024 when its trading revenue surpassed $20 billion for the full year, driven partly by a boom in options trading and its growing presence in fixed income ETFs. Citadel Securities, backed by Ken Griffin’s broader empire, has similarly posted record figures as it expanded into new asset classes and geographies.
There’s also the regulatory dimension to watch. Market makers of HRT’s scale now account for a significant share of daily trading volume in US equities and options. That concentration has drawn scrutiny from the SEC and other regulators who worry about systemic risk.
