Football is officially back, and Polymarket promo code SIBONUS unlocks a $20 bonus when you deposit $10 on Tuesday, August 25.

Week 0 gives you immediate trading opportunities. The North Carolina versus TCU game in Dublin kicks off the college football season with a Power conference matchup on a neutral field. If you predict UNC wins, your bonus funds can support that trade. If TCU covers the spread instead, you’ve learned how Polymarket works without wagering your deposit. The same flexibility applies to San Jose State versus USC, NC State versus Virginia, and Memphis versus UNLV later that evening.

MLB dominates Tuesday’s volume with Astros versus Yankees, Dodgers versus Braves, and Brewers versus Mets all offering compelling trading angles. The Dodgers-Braves matchup stands out as the strongest pure competition on the board. You could trade on whether the Dodgers win, whether the total runs exceed a certain threshold, or which team scores first. Your $20 bonus gives you capital to test multiple predictions across the slate.

The WNBA’s Sky versus Sun game rounds out Tuesday evening. Chicago is regrouping after playoff elimination, while Connecticut hosts the contest at Mohegan Sun Arena. Trading on WNBA outcomes alongside baseball and football lets you diversify your prediction portfolio on a single day.
