The near identical odds across both platforms point to broad agreement among traders about the tournament’s likely outcome, even as the two markets differ sharply in size and structure.

Kalshi led all platforms with roughly $33.0 billion, or 65.1% of the total. Polymarket followed with $10.70 billion, accounting for 21.1%, while its separate Polymarket US entity added $3.88 billion, or 7.7%. Combined, those three platforms represented nearly 94% of all recorded volume.

The remaining activity was split among smaller venues, including Crypto.com at $943.7 million, Opinion at $756.2 million, Limitless at $570.2 million, Predict.fun at $558.8 million, Hyperliquid at $176.6 million, and a combined “Other” category totaling $98.4 million. The distribution shows a market still concentrated among a small number of dominant platforms, even as new entrants continue to compete for volume.

For bettors, the data offers a clear signal heading into the tournament. France enters as the consensus favorite across both major platforms, while Argentina and Spain occupy a tightly bunched second tier.
