World Cup 2026 Prediction Markets: USA and Brazil Dominate the Odds, While Golf on Kalshi Breaks Records with $231 Million
Analyzing the current dynamics on leading decentralized prediction platforms, I clearly see how real-time sports betting markets reflect the balance of power at the 2026 World Cup. The US and Brazil national teams have firmly established themselves as favorites in their matches, while simultaneously, a real frenzy has erupted on the Kalshi exchange around the US Open golf tournament, which has already attracted hundreds of millions of dollars.
USA vs. Australia: Undisputed Leadership
In the Group D match between the USA and Australia, the market is nearly unanimous. On Polymarket and Kalshi, the probability of an American victory is estimated at 62% (the contract trades at $0.61), while a draw accounts for 22%, and an Australian win only 18%. This scenario formed after the confident start of the US team, which crushed Paraguay 4:1. Australia, in turn, also began the tournament with a win, defeating Turkey 2:0, making this head-to-head match crucial for advancing to the playoffs. The market volume on Kalshi for this match has exceeded $15.9 million — an indicator of colossal interest from traders.
Brazil and Other Matches of the Day
The Brazilian national team looks like an even more clear favorite in their game against Haiti. Polymarket estimates the Brazilians' success at 89% with a contract price of $0.89, while Haiti accounts for only about 4%, and a draw 8%. The market volume for this game was around $3.64 million. It is important to note that Brazil started the tournament imperfectly, drawing with Morocco in the first round, so a confident victory over Haiti is critically important for the pentacampeões. In other matchups of the day, the odds also favor the stronger teams: Morocco ($0.58) vs. Scotland, and Turkey ($0.47) vs. Paraguay.
Golf on Kalshi: $231 Million and a New Record
Special attention deserves the surge in betting on the US Open golf tournament on the Kalshi exchange. The market for the winner has amassed a colossal volume — about $231 million, making it one of the largest sports markets on the platform. During the second round, American Wyndham Clark became the odds leader with a 20% probability of winning. He is followed by Briton Matt Fitzpatrick (12%) and Rory McIlroy (8.4%). The 126th US Open tournament takes place from June 18-21 at the Shinnecock Hills Golf Club in New York State, where 156 players compete for the title. Such a high betting volume confirms my long-standing hypothesis: prediction markets are rapidly covering not only football but also other sports, becoming a full-fledged tool for analysis and speculation.
Expert opinion from Cryptalist: The record volume of $231 million on the golf tournament on Kalshi is not just an anomaly, but a clear signal of market maturity. Traders are increasingly diversifying their portfolios beyond traditional mainstream events. For investors, this means that platforms like Polymarket and Kalshi are becoming indispensable indicators of public sentiment and liquidity that should be considered when analyzing global trends.
