Inter Miami CF vs. Chicago Fire FC - More Markets

Platform comparison

Market context

Inter Miami CF and Chicago Fire FC were due to meet in MLS on 22 July at 7:30 pm ET, with this “More Markets” contract settling on whether side bets from that match resolved a certain way by the close of the window. The crowd-implied probability on Polymarket is 0% YES, which usually means the market is either still unpriced, thinly traded, or that participants are treating the proposition as effectively out of the money rather than genuinely impossible.

Comparable pricing shows why that reading should be handled carefully. Smarkets listed Chicago Fire as a very short-priced favourite at 1.04, with Inter Miami at 11 and the draw at 3.3, while another odds comparison page captured the same fixture in decimal format without a clear Polymarket-style probability framing. That difference matters: Polymarket and Kalshi display implied probability directly, whereas Betfair and Smarkets surface decimal odds and then layer on exchange commission or fees, so a near-zero YES price on one venue can still correspond to a tradable long shot elsewhere if the underlying market is illiquid or narrowly defined.

The main catalysts are late team news, starting line-ups, and any schedule changes affecting the match itself, because “More Markets” contracts often depend on specific in-game or derivative outcomes rather than the final score alone. Traders should watch for official MLS and club announcements close to kick-off, plus any liquidity shifts after line-up release, since a single star absence or weather delay can move related props far more than the headline 1X2 market. Inter Miami–Chicago fixtures also tend to attract higher attention because of their goal-heavy profiles, which can widen gaps between exchange pricing, bookmaker odds, and crowd sentiment.
