Prediction markets for the 2026 FIFA World Cup winner are showing impressive momentum. The total betting volume on the two leading platforms—Polymarket and Kalshi—has nearly reached the $5 billion mark. This clearly illustrates how major sporting events are becoming a powerful catalyst for the entire industry of decentralized and regulated prediction platforms.
Polymarket: Leader with Nearly $4 Billion in Volume
On Polymarket, the volume of the "2026 World Cup Winner" market reached $3.97 billion. The platform sees a clear favorite—the French national team with a 33% win probability, which is 16% higher than at the start of the tournament. Argentina takes second place with 18% (up 4 percentage points), and England is third with 15%. Spain rounds out the top four with 13%, although its chances have decreased by 3% over the past day.
Notably, the market's top trading volumes are not led by the favorites. The highest daily turnover was recorded for bets on the USA at $135.76 million, followed by Morocco ($132.59 million) and Norway ($108.37 million). This indicates high speculative activity around teams with lower but more volatile chances.
Kalshi: Nearly $1 Billion and a Similar Picture
On the Kalshi platform, the total volume of the World Cup winner market reached $1.01 billion. The distribution of favorites is almost identical: France leads with a 34.2% probability (down 0.5% over the day). Argentina is in second place with 18.4%, and England is third with 14.2%, with its chances increasing by 7.7 percentage points. Spain holds steady at 13%, while Portugal and Norway are estimated at 6.4% and 5.4%, respectively.
Analysis and Conclusions
The alignment of estimates on two independent platforms strengthens the significance of the signal. The differences are only in minor details, confirming market consolidation around the same favorites. Further betting dynamics will directly reflect the course of the tournament itself and the shifting odds as teams advance.
My expert opinion: The growth in volumes on decentralized prediction platforms is not just hype around the World Cup. It is a clear indicator that prediction markets are becoming a full-fledged tool for risk hedging and speculation. The fact that volumes on Polymarket are 4 times higher than on Kalshi speaks to the dominance of a crypto-native audience willing to take on counterparty risks for the sake of having no restrictions. Keep an eye on the dynamics of France and Argentina's chances—they will set the tone in the market over the coming weeks.
