Susquehanna International Group

What Susquehanna International Group does

Susquehanna International Group (SIG) is a privately held global quantitative trading firm founded in 1987 as an options trading firm on the Philadelphia Stock Exchange. Headquartered in Bala Cynwyd, Pennsylvania, the firm operates 16+ offices worldwide and employs 3,500+ people, including 1,000+ technology professionals. SIG applies machine learning, decision science, and game-theoretic reasoning to proprietary trading and market-making across options, equities, futures, and derivatives markets globally. The firm runs substantial proprietary technology infrastructure, including 20,000+ servers, to support low-latency execution and quantitative research.

Beyond its core quantitative trading operations, SIG operates multiple business lines: Institutional Sales, Predictions (including the Rothera prediction market platform), Growth Equity, Sustainable Investments, Venture Capital, and River's Edge. These extensions broaden the firm from a pure prop trader into a diversified financial services and principal investment platform. In January 2026, SIG formed a joint venture with Robinhood by acquiring a 90% stake in MIAX Derivatives Exchange for $88M, vertically integrating into exchange infrastructure. In March 2026, SIG partnered with BitGo to bring institutional-grade access to prediction markets, and has actively deployed venture capital into companies including Deccan AI, Gushwork, Sahi, Rialo, Snabbit, and Tint World.

SIG's revenue model is multi-stream: bid-ask spread capture and proprietary positioning in core market-making; institutional sales commissions; investment gains from growth equity, venture, and sustainable investing portfolios; and emerging fees from prediction market operations. As a private firm, SIG does not publicly disclose revenue, but its scale, headcount, and global footprint place it among the largest quantitative trading firms globally. Customer relationships are predominantly institutional and exchange-mediated, providing a diversified counterbase with low single-customer concentration risk.
