In September 2026, promotional activity shifted toward college football and the NFL. Major college football Week 2 matchups have driven significant activity across sports prediction markets and betting platforms. Market probabilities for key matchups include Alabama as a heavy favorite against Kentucky with a 79% moneyline probability, and Missouri favored against Kansas. In other matchups, Louisville holds a near-certain implied probability of victory over Villanova, while market data suggests a challenging outing for Ohio State quarterback Julian Sayin against the Texas defense. To coincide with the football season, various platforms have released new incentives. Polymarket has issued several referral codes providing users access to trading bonuses for NFL, MLB, and college football markets. Specifically, Polymarket is offering a $50 trading bonus for new US users who deposit $10. Other operators have introduced specialized features and offers. BetMGM has launched ‘BetDefense’, which provides a cash stake refund if a named player is injured in the first quarter, and ‘Ultimate Teams’, a free-to-play game with a weekly $50,000 bonus bets jackpot.
