Polymarket Promo Code for Spurs vs Knicks Game 4: Claim Your $20 Bonus

The San Antonio Spurs and New York Knicks are set for a pivotal Game 4 of the NBA Finals on Wednesday night, and you can trade on the action with a $20 bonus from prediction market promos. The Polymarket promo code "SIBONUS" unlocks this welcome offer as of June 10. New users in eligible states can claim the bonus by entering the code during registration and making a $20 deposit.

How the Polymarket Promo Code Works for Game 4

The Polymarket promo code "SIBONUS" gives new traders a $20 bonus to start predicting outcomes on the Spurs versus Knicks matchup. Unlike traditional sportsbooks, Polymarket operates as a prediction market where you trade on event outcomes rather than place bets. When you enter the code during sign-up and deposit $20, you'll receive your bonus funds to trade with immediately.

Here are the key terms and conditions for claiming this offer:

Available in all U.S. states except Nevada
You must be physically located in an eligible state
Code "SIBONUS" must be entered during registration
Photo ID verification required (driver's license or passport with selfie)
Minimum $20 deposit required to activate the bonus

For Game 4, imagine trading on whether the Knicks extend their series lead to 3-1 or the Spurs force a Game 5. If you predict the Knicks win and they do, your position gains value. If the Spurs pull off the upset, your position loses value. Polymarket lets you trade these predictions throughout the game as odds shift based on live action and momentum.
