Hudson River Trading (HRT), a leading high-frequency trading firm, reportedly achieved a record $6.4 billion in trading revenue during the first quarter of 2026. This figure, if accurate, would set a new benchmark in the quantitative trading industry, surpassing the annual revenues of major competitors like Citadel Securities and Jane Street. However, as a private company, HRT does not publicly disclose its financials, leaving the veracity of this claim uncertain. HRT, which entered the cryptocurrency market in 2020, is a significant liquidity provider, reportedly handling around 15% of spot Bitcoin and Ethereum volumes on centralized exchanges. The firm's growing influence in the crypto space underscores the potential impact of its trading activities on market depth and volatility. Despite the lack of official confirmation of the $6.4 billion revenue, HRT's recent hiring spree suggests ongoing business expansion.
