MLB, college football and tennis are all heating up, giving Kalshi users plenty of markets to trade this week. New users can enter promo code FOXSPORTS to get a $25 bonus and jump into the action.

College football Week 1 kicks off Thursday, bringing the first full slate of the 2026 season. Meanwhile, MLB continues its push toward the postseason with races tightening across both leagues.

The U.S. Open has already delivered major drama, with four-time champion Novak Djokovic suffering a stunning first-round exit to Mariano Navone. The men's draw is wide open after Jannik Sinner withdrew with a knee injury and Arthur Fils was eliminated, while Carlos Alcaraz returned from a four-month layoff with a win.
