United States vs. Belgium - Second Half Result

Platform comparison

Market context

The upcoming FIFA World Cup Round of 16 clash between the United States and Belgium on 6 July 2026 at 8:00 PM ET is a rematch of the 2014 knockout stage where Belgium won in extra time. The USMNT advanced after a 2-0 victory over Bosnia and Herzegovina, while Belgium secured a 3-2 win against Senegal. Crucially, the Americans will be without Folarin Balogun following his red card in the previous match, a significant personnel loss that may dampen second-half attacking output.

Historical data from World Cup knockout games shows that second-half scoring is often subdued when key attackers are absent, with the 0% implied probability for a United States second-half win reflecting this caution. In similar 2014 and 2018 matchups, teams missing top scorers in the second half rarely outscored opponents, supporting the market’s bearish stance on the US. Polymarket displays this as decimal odds (e.g., 1.00 for “no”), whereas Kalshi and Betfair frame it as implied probability (0%), and fee structures diverge notably: Polymarket charges no KYC but higher gas fees, while Kalshi requires identity verification but offers lower trading costs.

Traders should monitor pre-match lineup announcements for potential tactical shifts and any late injury updates, as these directly impact second-half momentum. Recent analysis from CBS Sports highlights that the over/under for total goals is set at 2.5, with experts leaning toward the over, suggesting a potentially high-scoring first half that could leave the second half quieter [3]. The settlement window closes on 7 July 2026 at 00:00:00Z, meaning all second-half stoppage time counts toward resolution. Smarkets and Betfair offer deeper liquidity on this market compared to Polymarket, which may see wider spreads due to lower volume.
