Cryptocurrency platforms for betting on event outcomes are experiencing an unprecedented surge. The total volume of bets on the winner of the 2026 FIFA World Cup on two leading platforms — Polymarket and Kalshi — has nearly reached the $5 billion mark. This figure clearly demonstrates how much prediction markets are attracting capital ahead of major sports tournaments.
Analyzing data directly from the platforms, we see that Polymarket confidently holds the lead: the volume of its "2026 World Cup Winner" market is nearly $4 billion. Kalshi, while trailing behind, also shows an impressive result, exceeding $1 billion. This concentration of liquidity makes these platforms key indicators of public opinion and market expectations.
Tournament Favorites: Market Consensus
Notably, both platforms show a high degree of convergence in assessing the favorites. The French national team is the undisputed leader with a probability of winning around 33-34%. On Polymarket, the chances of the French have increased by 16% recently, indicating growing trader confidence. Argentina, the reigning champion, is in second place with 18%, and England rounds out the top three with 15% on Polymarket and 14.2% on Kalshi.
Interestingly, Spain, despite its high ranking, shows a slight decrease in probability — its chances are estimated at 13%. However, curious anomalies are observed within the market. For example, in terms of daily trading volume on Polymarket, the leaders are the USA ($135.76 million), Morocco ($132.59 million), and Norway ($108.37 million). This points to high speculative interest in these teams, despite their objectively lower chances of an eventual victory.
A Unified Market Signal
The alignment of estimates on two independent and large platforms — Polymarket and Kalshi — is a strong confirmation of the current market consensus. The differences in details are minimal and are explained by different user structures and liquidity. However, the overall direction is clear: the market considers France the main contender for the trophy, and the battle for second and third place will be extremely intense.
Analyst's Comment: The growth in betting volume to $5 billion is not just a number. It is a signal of the maturity of cryptocurrency prediction markets as a tool for hedging and speculation. Further dynamics will directly depend on the course of the tournament itself. Any sensation or injury to a key player will instantly be reflected in the odds, creating volatility that attracts more and more professional traders to this segment.
