Kalshi Promo Code SIBONUS: Get up to $500 Bonus When You Trade MLB on Monday, July 27

Monday, July 27 brings a full slate of Major League Baseball action, and the up to $500 trading bonus from Kalshi makes it the perfect time to start trading. You'll need the Kalshi promo code SIBONUS to unlock this offer. With 12 games spanning from early afternoon in Texas to late-night finishes on the West Coast, there's plenty of opportunity to explore prediction market promos while trading on matchups like Phillies-Marlins, Braves-Mets, and Astros-Angels. Sign up today and deposit at least $25 to get started.

How the Kalshi Promo Code SIBONUS Works for Monday's MLB Action

The Kalshi promo code SIBONUS delivers a variable bonus that rewards new traders with up to $500 in trading credit. When you register with the code and make an initial deposit of $25 or more, you unlock the bonus opportunity. The key is simple: trade at least $25 in event contracts, and your bonus credit posts regardless of whether those trades win or lose.

Here's what the bonus structure looks like. Seventy percent of participants receive $15, 24 percent receive $35, 5 percent receive $75, 0.65 percent receive $100, and 0.35 percent receive $500. You won't know which tier you'll land in until you claim the offer, but every new user gets something. Once credited, your bonus must be used within 7 days or it expires, so plan to trade on Monday's slate or the games that follow shortly after.

The terms are straightforward. You must be physically present in an eligible state (Nevada is excluded), provide a government ID or passport with a matching selfie, and complete your $25 in trades to trigger the bonus. Whether you're trading on the Yankees-White Sox matchup or waiting for the late-night Brewers-Giants game, every dollar you trade counts toward unlocking your reward. The bonus credit itself cannot be withdrawn; it must be used to place additional trades within Kalshi's platform.
