NFL Prediction Market Apps for Week 3: Trade on Kalshi & Polymarket Now

Week 3 NFL prediction markets are being promoted with new-user offers on Kalshi and Polymarket, alongside other platforms. The article says 14 games run from the 1 p.m. ET window to a late kickoff in Rio de Janeiro, finishing with Rams-Broncos at 8:20 p.m. ET on NBC. It notes that prediction markets price contracts in cents rather than American odds; for example, a side at 62¢ would settle at $1 if correct and zero otherwise, with implied probability reflected in price. It highlights a combined $2,250 welcome-offer “stack” for those eligible across all promos. It also describes settlement mechanics where positions can be closed as the board moves. Polymarket’s code HANDLE turns a $10 deposit into $50 bonus power, while Kalshi’s code HANDLE targets a $25 offer after $25 qualifying volume, and Novig offers $25 in trade credits after a $10 deposit.
