    Frequently asked questions

    Was it legal to trade on the 2026 World Cup in the US?

    Which prediction market was best for World Cup trading?

    Kalshi was favored for outright winner markets (Spain was trading around 20¢ pre-tournament). Sleeper was popular for social, match-by-match trading, and Chalkboard excelled in player props, such as the Golden Boot market, which the talisman won with 10 goals.
