Susquehanna International Group Portfolio holdings
Susquehanna International Group (SIG), founded in 1987 by Jeff Yass and a group of friends, is a privately held global quantitative trading and technology firm headquartered in Bala Cynwyd, Pennsylvania. Specializing in trading equities, fixed income, commodities, derivatives, and ETFs, SIG has grown into a major market maker, handling around 600 equity options and 45 index options across exchanges like the CBOE, while employing over 3,000 people worldwide. The firm leverages a data-driven, probabilistic approach—rooted in the founders’ poker-playing days—to provide liquidity and competitive pricing in financial markets, with additional ventures in private equity, venture capital (notably an early investment in ByteDance, TikTok’s parent company), and sports betting analytics. Known for its innovative culture and use of game theory, SIG operates offices across North America, Europe, Asia, and Australia, maintaining a low-profile yet influential presence in global finance.
