Prediction markets are betting on Spain: 92% on the start and status as the main favorite for the 2026 World Cup.
Spain's national team approaches its debut match at the 2026 World Cup against Cape Verde as the absolute favorite. Data from leading decentralized prediction platforms Polymarket and Kalshi estimate the probability of "La Roja's" victory at over 90%, while simultaneously naming the team as the main contender for the title.
The tournament, which for the first time in history will be held across three countries — the USA, Canada, and Mexico — has gathered a record 48 teams. For Cape Verde, this is a historic debut at the world championship, while Spain takes the field as the reigning European champion and winner of the 2010 World Cup. The contrast in class and experience is obvious, and the markets clearly reflect this.
Spain vs. Cape Verde: Market Analysis
On Polymarket, the opening match of Group H attracted approximately $14.59 million in bets. The contract for a Spain win is trading at $0.93, implying a 93% probability. A draw is valued at $0.055, and a Cape Verde success at just $0.023. The handicap for Spain is -2.5 goals, and participants set the total at 3.5 goals. The Kalshi platform shows a similar picture: 92% for a Spain win, 7% for a draw, and only 3% for an upset. The market volume on this platform reached $8.29 million.
Such unanimity among traders fully correlates with expert assessments. Spain dominates in terms of squad and playing class, while Cape Verde, having qualified for the World Cup for the first time, is objectively an underdog. A confident victory for the favorite is expected.
Spain — Leader in the Title Race
Both platforms agree not only on the first match but also on the eventual tournament winner. On Polymarket, the probability of Spain winning the 2026 World Cup is estimated at 16.3%. They are followed by France (16.2%), Portugal (10.8%), and England (9.7%). Argentina rounds out the top five with 8.1%. The total volume of the winner market on Polymarket has exceeded $2.35 billion, highlighting the enormous interest in these predictions.
On Kalshi, the balance of power is almost identical: Spain leads with 17.4%, France trails by one percentage point (16.4%), and Portugal closes the top three with 11.6%. The market volume on this platform amounted to about $283 million.
In addition to the central match, other games will take place on June 15. According to Polymarket, a Belgium victory over Egypt is valued at $0.62, Uruguay's success over Saudi Arabia at $0.68, and in the pair Iran vs. New Zealand, Iran is the favorite at $0.54. Kalshi gives similar percentages: Belgium — 62%, Uruguay — 67%, Iran — 52%.
Analytical commentary from Cryptalist: Prediction markets, especially decentralized ones, are becoming an increasingly accurate indicator of collective opinion. In this case, we see an almost complete overlap with classic bookmaker lines and expert consensus. However, it is worth remembering that football is not mathematics. Spain is the undisputed favorite of the group and the tournament, but the contract price for a win at 93% leaves very little room for error. Any underestimation of the opponent or an unexpected scenario could lead to a sharp correction. For investors in prediction markets, this is a high-risk zone with low potential returns.
