New users who sign up today can claim the best Team USA betting offer available for tonight's World Cup Round of 16 matchup between the USMNT and Belgium. Kickoff is at 8 p.m. ET at Lumen Field in Seattle, and Action Network's top-rated sportsbook and prediction market partners are all live with welcome offers — including up to $1,550 in bonuses — before the opening whistle. The bet365 bonus code TOPACTION and BetMGM bonus code ACTION1550 are the two highest-value best Team USA betting app offers available right now, and you can claim both in minutes.
Tonight is as big as it gets for the USMNT. The U.S. men's national team hasn't reached the quarterfinals of a World Cup since 2002, but a win at home in Seattle tonight changes that. Star forward Folarin Balogun was set to miss the match after getting a controversial red card against Bosnia and Herzegovina, but his ban was suspended by a FIFA committee, making him available to play on Monday night. With Balogun back, Pulisic healthy, and a sold-out Seattle crowd behind them, the USMNT enter this match with every advantage they could ask for.
