The trading volume on decentralized prediction platforms Polymarket and Kalshi for the "2026 FIFA World Cup Winner" market has approached the $5 billion mark. This is a colossal figure that clearly demonstrates how strongly traditional sporting events drive capital inflows into the prediction market sector.
According to data from the platforms themselves, Polymarket's cumulative betting volume has already exceeded $3.97 billion, while Kalshi, which is more focused on the regulated U.S. market, reported a figure of over $1.01 billion. Despite the difference in volume, both platforms show remarkable synchronization in their assessment of the favorites.
France — the undisputed leader
On both Polymarket and Kalshi, the French national team is considered the main contender for the trophy. The probability of its victory is estimated at 33% and 34.2%, respectively. Over the past day, the chances of the French on Polymarket have increased by 16%, although on Kalshi, conversely, they have adjusted downward by 0.5% — indicating high volatility in opinions just before the start of the tournament.
Argentina confidently holds the second position with a probability of about 18% on both platforms. England rounds out the top three with 14-15%. Spain holds steady at 13%, although its position has weakened slightly over the last day. Portugal (6.4%) and Norway (5.4%) close out the list of teams that traders consider real contenders for victory.
Volume paradox: USA and Morocco lead in trading activity
An interesting detail: the largest daily trading volume on Polymarket did not come from the favorites at all. The leader in this indicator was the USA with $135.76 million per day, although the chances of the American team winning are estimated quite modestly. They are followed by Morocco ($132.59 million) and Norway ($108.37 million). This suggests that traders are actively hedging risks and playing on the odds of underdogs, expecting surprises.
The coincidence of estimates on two independent platforms — Polymarket (cryptocurrency) and Kalshi (regulated by the CFTC) — only reinforces the significance of these signals. The difference lies only in minor details, which confirms a high degree of consensus among market participants.
Cryptalist Analytics
From a professional analyst's perspective, the current volumes are not just hype around the World Cup. This is a clear indicator that prediction markets have finally ceased to be a niche pastime. The convergence of interests between crypto enthusiasts and institutional players (via Kalshi) creates enormous liquidity. Further dynamics of bets will directly depend on unexpected results in the playoffs, and it is here, rather than in assessing favorites, that the greatest potential for volatility and profit lies. Watch for shifts in probabilities — this is the best indicator of the real balance of power on the field.
