Susquehanna International Group (SIG) deployed $500 million to bet on the 2026 World Cup, primarily through prediction markets. This significant investment underscores SIG's expansion into this rapidly growing sector, where they act as market makers, facilitating trades for large institutional investors like hedge funds and even sports teams. The firm leverages its expertise in market making to provide liquidity and manage risk in these nascent markets, which often suffer from shallow trading volumes.

SIG's involvement highlights a broader trend of prediction markets gaining traction, moving beyond individual bettors to attract substantial institutional capital. The firm's head of macro trading and prediction markets, Jeremy Maletz, previously discussed Susquehanna’s strategy for market making, emphasizing their approach to hedging risk and generating profits from these contracts. Their participation helps validate prediction markets as a legitimate financial tool for hedging and speculation.

While prediction markets are gaining institutional interest for hedging, there are still regulatory ambiguities. For instance, a Spanish soccer club recently used Kalshi, a prediction market platform, to hedge against potential relegation losses, illustrating the practical application of these markets for managing financial risks related to sports outcomes. However, some countries, including Spain, have temporarily banned such platforms for operating without gambling licenses, raising questions about the legal and ethical landscape of these emerging financial instruments.
