France World Cup Winning Odds Climb to 35% as Polymarket Volume Tops $3.9 Billion
France has emerged as the clear favorite to win the 2026 FIFA World Cup, according to betting activity on Polymarket and Kalshi, two prediction market platforms that have processed billions of dollars in wagers on the tournament outcome.
Polymarket’s World Cup Winner market has generated $3.9 billion in total trading volume. France sits at the top with a 35.4% implied probability of winning the tournament, backed by more than $94.5 million in individual volume on that outcome alone. Argentina, the defending champion, holds second place at 16.8%, with $99.8 million wagered—the highest single-volume figure in the market. Spain follows at 12.4% with $85.0 million, while England and Brazil sit at 7.1% and 7.0% respectively. Portugal rounds out the leading contenders at 6.0%.
Beyond the outright winner market, bettors have placed money across a wide range of outcomes. Kylian Mbappe leads the Golden Boot market at 51%, ahead of Lionel Messi at 37%. Mbappe also tops the Golden Ball market for best overall player at 38%, with Messi at 26%. Traders give France a 55% chance of reaching the final, compared to 38% for Argentina. On a continental basis, Europe carries a 66% chance of winning the tournament outright, while South America sits at 28%. Argentina is favored at 86% to reach the quarterfinals, ahead of Brazil at 70%. In the semifinal market, France leads at 79% to Argentina’s 63%.
Smaller markets show additional detail. France is favored at 70% to produce the tournament’s top scoring nation, with Argentina at 20%. Among individual players, Michael Olise is favored at 61% to score next over Declan Rice at 25%.
Kalshi’s World Cup Winner market has reached $961,962,750 in trading volume, with France trading at 35.5 cents on the dollar—matching its Polymarket probability closely. Argentina follows at 17.7%, up 0.6 percentage points, while Spain sits at 12.6%, down slightly by 0.1%. 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.
The World Cup markets are part of a broader expansion in prediction market activity. Platforms collectively processed about $50.69 billion in monthly notional volume in June 2026. Kalshi led all platforms with roughly $33.0 billion (65.1% of total). Polymarket followed with $10.70 billion (21.1%), while its separate Polymarket US entity added $3.88 billion (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.
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.
