Polymarket, Kalshi and Novig update “sign-up codes” for Thursday Night Football

Three US prediction markets have their sign-up codes live at once for the start of NFL Week 3. Polymarket and Kalshi have confirmed their promo codes, referral codes and invite codes are active for Thursday Night Football, when the Falcons visit the Packers at Lambeau Field at 8:15 p.m. ET, and Novig’s new promo codes are live across the same five Advance Local sites. On Cleveland.com, the Polymarket promo code is CLEVE , the Kalshi promo code is CLEVELAND55 , and the Novig promo code is CLEVELAND . The three offers stack differently. The Polymarket promo code unlocks a $50 bonus on a $10 deposit—$60 total to trade. The Kalshi promo code CLEVELAND55 carries a limited-time upgraded bonus of $55 on a $25 deposit—$80 total—more than double Kalshi’s standard $25 match, and Kalshi has now carried the upgrade into a second week without announcing an end date. The Novig promo code CLEVELAND unlocks a $25 bonus on a $10 deposit—$35 total. All three are for new US accounts only, and all three are verified and active as of Thursday, September 24, 2026. This is a network-wide update. Each of the five Advance Local newsrooms—Syracuse.com, SILive.com, OregonLive.com, MassLive.com, and Cleveland.com—has its own verified code on each platform, and all 15 are confirmed active. Here are the codes by publication: What is the Polymarket promo code for Thursday Night Football?
