Kalshi Promo Code SIBONUS: Trade MLB and WNBA, Get up to $500 Bonus on Tuesday

Tuesday, July 28 brings a loaded sports slate with 15 MLB games and a marquee WNBA matchup, making it the perfect day to explore Kalshi promo code opportunities. New users can claim up to $500 trading bonus by signing up with code SIBONUS and trading at least $25 in event contracts. Whether you're interested in Cubs-Cardinals, Mariners-Dodgers, or the Indiana Fever visiting the Seattle Storm, Kalshi's prediction markets let you trade on real outcomes. The code is required to unlock this welcome offer, and you'll need to make an initial deposit of at least $25 to get started.

How the Kalshi Promo Code SIBONUS Works for Tuesday's Games

The Kalshi promo code SIBONUS delivers a variable bonus structure designed to reward new traders. After you register with the code and deposit $25 or more, you'll trade at least $25 in contracts across any of Tuesday's matchups. Once you complete $25 in trades, your bonus credit is awarded regardless of whether those trades win or lose. This means you could trade on the Yankees-White Sox game, the Braves-Mets rivalry, or the Fever-Storm rematch and still unlock your reward.

Here's what you need to know about the bonus structure and key terms:

The bonus is variable: 70% of participants receive $15, 24% receive $35, 5% receive $75, 0.65% receive $100, and 0.35% receive $500
You must deposit at least $25 and trade at least $25 in event contracts to trigger the bonus
Bonus credit must be used within 7 days of being granted or it expires
The code SIBONUS is required at signup to claim this offer
Available in all states except Nevada
You'll need to verify your identity with a government ID or passport and a selfie

The beauty of this offer is that your trades don't need to win for you to earn the bonus. Trade on whether the Astros beat the Angels, whether the Brewers-Giants stays under a certain run total, or any other market available on Tuesday. Your bonus credit unlocks after you meet the $25 trading threshold, giving you additional funds to continue trading on future events.
