Seattle Sounders FC vs. Querétaro FC - More Markets

Platform comparison

Market context

Seattle Sounders FC are playing Querétaro FC in the Leagues Cup, with the market on *more markets* effectively asking whether secondary player, goals, corners or first-scorer props will be posted and settled before the window closes at 19:30 UTC. On Polymarket, the related match-winner market has Seattle priced at about 50% and Robinhood shows a similar 46¢-30¢-29¢ split, which is in the same range as Kalshi’s 46% board price for Seattle, while Betfair and Smarkets typically express the same view as decimal odds rather than direct implied probability. [1][2][7]

For context, this is a useful spot to compare how books normalise the same football match differently: Polymarket and Kalshi quote cents or percentages, while exchange-style venues such as Betfair and Smarkets are usually judged by decimal prices and commission, so a near-50% team view can look closer to 1.85-2.05 once fees are considered. The current crowd-implied 100% YES on the *more markets* contract is therefore less a statement about Seattle’s superiority than a sign that the platform expects additional market listings before expiry, which is consistent with the wider prop menu already visible on related feeds such as first team to score and corners. [3][4][12]

The main catalysts are the pre-match market release schedule, any last-minute line-up or injury updates, and whether the operator keeps adding correlated props as kickoff approaches. Leagues Cup preview coverage notes both sides need a result after opening defeats, and Seattle’s official match listing confirms the fixture timing, so traders should watch for late roster news and whether the platform posts further derivatives before the settlement clock runs out.
