Susquehanna deepens prediction market push as World Cup drives record volumes
The trading giant's prediction market desk is reshaping how institutions think about event-driven risk, with platforms hitting $50 billion in monthly volume for the first time
Susquehanna International Group is making its biggest bet yet on prediction markets. The quantitative trading powerhouse has been steadily building out its prediction market infrastructure, launching dedicated desks and forging partnerships that position it as the institutional backbone of a sector that just crossed a major milestone: $50 billion in monthly trading volume.
The catalyst? The 2026 FIFA World Cup, which turned prediction markets into one of the hottest corners of finance this summer.
From market maker to market shaper
SIG’s prediction market ambitions started taking concrete shape when it became Kalshi’s first official market maker in 2024. Operating under its Susquehanna Predictions banner, the firm has since expanded its footprint considerably. The most notable development is Rothera, a prediction market exchange born from a joint venture between SIG and Robinhood.
Rothera’s debut month was June 2026. The platform processed roughly $2 billion in notional volume right out of the gate, capturing approximately 7% of the US prediction market share in its first month of operation.
Meanwhile, Kalshi itself posted approximately $33 billion in trading volume during June 2026.
The World Cup effect
The 2026 World Cup pushed the entire prediction market ecosystem past $50 billion in monthly volume for the first time ever.
SIG has been vocal about its vision for using prediction markets as legitimate hedging instruments for institutional clients. The firm’s leadership has discussed this thesis in interviews and podcast appearances, framing prediction markets not as gambling venues but as price discovery mechanisms for real-world events.
The institutional adoption thesis
By becoming the first market maker on Kalshi and co-launching Rothera with Robinhood, SIG has positioned itself on both sides of this equation. Robinhood brings a massive retail user base and brand recognition among younger traders. SIG brings institutional-grade market-making capabilities. Together, they’ve created a platform that can serve both audiences.
