Kalshi expands World Cup combo props and advance markets, tracks live knockout odds
Kalshi is expanding its World Cup prediction market lineup with combo proposition markets and advance markets for knockout stage matches. The platform now offers regulation-time spread and over/under combinations for fixtures including South Africa-Canada and Congo DR-England, alongside traditional moneyline and first-goalscorer contracts. Live pricing shows Egypt at 61% to beat Australia and Argentina at 92% alongside Polymarket. A single trader wagered $73,000 on Canada to defeat South Africa on June 29, with a potential $100,000 payout.
Combo props and advance markets move Kalshi deeper into sportsbook territory, but the platform still releases prices without per-contract volume or open-interest data. That pattern — visible across the USMNT-Bosnia, Portugal-Colombia, and France-Norway fixtures — leaves traders guessing whether a 61% Egypt line reflects liquid conviction or thin-book drift. The $73,000 Canada bet is a whale signal, yet one trade does not prove market depth. For Kalshi, the World Cup is a live test of whether contract innovation can convert to revenue per dollar traded that rivals Polymarket's $1 billion annualized run rate, or whether headline prices without execution transparency cede the next marquee event to the liquidity-first playbook. The platform has weeks, not months, to close that gap before tournament attention fades.
