How the Kalshi Promo Code Works for Red Sox vs. Orioles Trading

The Kalshi promo code SIBONUS unlocks a variable bonus structure that rewards new traders immediately upon signup. You'll need to deposit at least $25 and complete $25 in trades on any available markets, including the Red Sox-Orioles game on Tuesday. Once you hit that $25 trading threshold, your bonus credit is awarded regardless of whether your trades win or lose. This means you could trade on Boston's momentum against Baltimore and still unlock your bonus even if the Orioles pull off an upset.

The bonus structure breaks down as follows: 70 percent of participants receive $15, 24 percent receive $35, 5 percent receive $75, 0.65 percent receive $100, and 0.35 percent receive $500. Your bonus credit must be used within seven days of being granted, or it expires. You cannot withdraw bonus credit directly from your account; it must be used for additional trades within Kalshi's platform. The offer is available in all states except Nevada, and you must be physically present in an eligible location to claim it.

Here are the key terms and conditions you should know before signing up:

  • Sign up with promo code SIBONUS during registration
  • Deposit a minimum of $25 to your account
  • Complete at least $25 in trades on any event contracts, such as the Red Sox-Orioles game
  • Bonus credit is awarded after you meet the $25 trading requirement, win or lose
  • Bonus credit expires seven days after being granted if unused
  • Bonus credit cannot be withdrawn; it must be used for additional trades
  • Offer is ongoing and available in all states except Nevada
