BetMGM's main offer gives new users up to $1,500 in bonus bets when they place a qualifying first wager using bonus code COVERS. COVERS explains that wagers over $50 are split into five bonus bets, each worth 20% of the original bet. Wagers of $50 or less generate one bonus bet equal to the full wager amount.
All bonus bets expire seven days after issue. Some states run a separate $150 promotion: after a $10 qualifying wager, players receive three $50 bonus bets, also expiring in seven days. These offers apply to NFL Week 4 Sunday matchups, and availability varies by state and operator.
Kalshi awards a $60 bonus after new users complete identity verification and make at least $25 in qualifying transactions. COVERS notes that Kalshi requires a government-issued ID or passport plus a selfie holding the ID. The $60 bonus must be used on Kalshi's Predictions product and expires seven days after being granted.
Polymarket offers a $25 trading bonus after sign-up, identity verification, a $10 deposit, and required trading activity. COVERS reports that combined bonuses across all platforms top $1,260 for new users willing to sign up for multiple services. Both platforms involve real contract-trading risk tied to sports and event outcomes.
BetMGM provides responsible-gambling features including betting-activity alerts, timeout options, and self-exclusion. The sportsbook offers 24/7 live-chat support and links to gambling helplines. These tools aim to help players manage their wagering and avoid problem gambling.
Players should review each platform's terms before claiming bonuses. Offers expire quickly—often within days—and bonus bets carry strict wagering limits. New users must verify identity and meet minimum deposit or transaction thresholds. Check your state's regulations, as promotional eligibility and bonus structures vary significantly by location.
