Hyperliquid’s prediction market upgrade, HIP-4, just crossed a milestone that even its most optimistic backers probably didn’t expect this fast. Open interest on the platform reached an all-time high of approximately $24.77M, driven almost entirely by traders betting on who will lift the 2026 FIFA World Cup trophy.
The numbers behind the World Cup frenzy
Weekly trading volume on HIP-4 hit $16.32M as of June 11, 2026. Of that, $9.63M, roughly 60%, came from World Cup price prediction markets alone. That represents a 20% increase week-over-week.
Sports-related markets now account for approximately 99% of all live open interest on HIP-4. Total HIP-4 open interest has since grown to around $51M, with sports OI contributing $49.52M of that figure. The champion market, where traders wager on the outright World Cup winner, is the dominant contract by a wide margin.
France, Argentina, and Spain are attracting the heaviest action. Every position is fully collateralized and settled in stablecoins within the Hyperliquid ecosystem.
