Yankees vs Mariners Kalshi Promo Code Details

The Kalshi promo code COVERS unlocks a $10 welcome bonus for new users in most U.S. states except Nevada. Unlike traditional sportsbook offers, this prediction market bonus requires you to trade $10 in event contracts to receive the reward. For the Yankees-Mariners series, you could predict outcomes like total runs scored or which team's pitching will dominate, given both rotations' early success.

Key terms include providing photo ID verification during registration, making a minimum $1 deposit, and completing $10 in contract trades. If you trade on Yankees-Mariners predictions and your contracts lose value, you still receive the full $10 bonus. Conversely, if your predictions prove accurate and gain value, you keep those profits plus the bonus. The offer is available to physically located users in eligible states who complete the verification process.

This welcome bonus stands out because you receive the reward regardless of your trading results, making it an attractive entry point for exploring prediction markets. For more options, compare best prediction market promos available.
