Our Reading
The numbers tell one story.
Kalshi and Polymarket’s World Cup contracts have shown mixed accuracy in predicting match outcomes, with early market pricing not always matching the eventual results. Despite this, the platforms have seen a surge in activity, with over 64,000 users engaging with the Argentina-Spain match page on Polymarket. The World Cup has reinforced the broader ascent of prediction markets in the US, where they are becoming part of the standard playbook for engaging with major events.
It’s a safe bet that the World Cup’s unpredictability will continue to drive interest in these markets.
