Details from the Macquarie Equity Research Report

Researchers at Macquarie compiled the figures from platform data across major prediction market operators and the numbers show clear acceleration in user participation during the World Cup period when interest in event contracts spiked across multiple categories including match outcomes and tournament progressions.

Data indicates the total volume surpassed previous monthly peaks by a significant margin and observers note that the surge aligns with broader patterns where major international sporting events draw increased trading activity into regulated prediction platforms.

Kalshi's Market Position and Growth Trajectory

Kalshi captured roughly $33 billion of the overall volume which gave the platform a 65 percent share and that figure represents an increase from its 57 percent share recorded in May according to the same analysis.

Analysts tracking platform performance point out that this gain occurred amid heightened competition yet Kalshi maintained its lead through expanded contract offerings tied directly to World Cup fixtures and related outcomes.

Those reviewing the report highlight how the platform's share expansion reflects both organic growth in active traders and strategic listings that captured attention during peak event windows.

Sports Contracts Drive Half of June Activity

Sports-related contracts accounted for roughly half of all trading activity during the month and this category included a wide range of FIFA World Cup propositions that attracted steady inflows from participants seeking exposure to specific game results and series developments.

Figures reveal that non-sports contracts still contributed substantial volume yet the sports segment provided the primary catalyst pushing the overall total past the $50 billion threshold for the first time in a single month.

Market participants who focused on these contracts often traded multiple times per event cycle and this repeated engagement helped sustain elevated daily averages throughout June.

Annualized Industry Rate and Future Projections

The Macquarie analysis projects an annualized industry rate exceeding $500 billion based on June performance and this extrapolation assumes continued momentum from ongoing and upcoming events that typically generate similar trading patterns.

Experts reviewing the data note that prediction markets have shown consistent expansion over recent quarters with each major tournament or election cycle adding measurable lifts to baseline volumes.

Platforms operating in this space now face questions about infrastructure capacity and liquidity depth as volumes scale toward the projected annual run rate.

Context Around the June 2026 Record

June 2026 stands out because it coincided with the FIFA World Cup which created natural alignment between real-world events and contract resolutions on prediction platforms and the timing amplified participation from both new and returning users.

Observers tracking sector trends point out that similar spikes have occurred around other global sporting events yet the absolute dollar figures reached in June represent a clear step change from prior benchmarks.

Activity levels remained elevated into early July as residual World Cup contracts continued to settle while new listings began to appear for subsequent competitions and political developments.
