Kalshi's SBWIRE Promo Code Unlocks $25 Bonus for New Users

Kalshi's promo code SBWIRE offers new users $25 in bonus credit once they register and place $25 worth of trades. This welcome offer ranks among the best on prediction market platforms because the credit lands regardless of whether their positions hit or miss.

The regular season is just over two weeks out, and Kalshi allows users to trade on hundreds of NFL markets, including Week 1 and Super Bowl futures. The platform also offers UFC, WNBA, MLB, PGA, politics, crypto, and more.

Kalshi operates as a federally regulated designated contract market under CFTC oversight, which is why it reaches most of the country. Currently, the promo code SBWIRE is live in 39 states plus Washington, D.C., but access to sports markets is tied up in ongoing legal challenges.
