Polymarket Promo Code Gives a $50 Bonus for Knicks vs Spurs NBA Finals Game 5 Prediction Markets in Texas

The New York Knicks are one win away from their first NBA championship since 1973, and you can trade on the action with a Polymarket promo code. Claim a $50 bonus on Saturday, June 13 by entering code SIBONUS during registration. This welcome offer gives you additional funds to trade on whether the Knicks will close out the Spurs in Game 5 at Frost Bank Center, or if San Antonio can force a Game 6 back in New York.

How the Polymarket Promo Code Works for the Knicks-Spurs Matchup

The Polymarket promo code SIBONUS unlocks a $50 welcome bonus when you sign up for an account. Unlike traditional sportsbooks, this offer requires you to deposit a minimum of $20 to activate the bonus, giving you a total of $70 to begin trading on prediction markets. You can use these funds to trade on the Knicks-Spurs Game 5 outcome or any other market available on the platform, from sports to politics to entertainment.

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

Code SIBONUS must be entered during registration
Available in all U.S. states except Nevada
Minimum deposit of $20 required to unlock the $50 bonus
You must provide valid ID verification, including a photo of your driver's license or passport and a selfie holding that ID
Social Security Number verification may be required
You must be physically located in an eligible state when claiming the offer

When you trade on the Knicks-Spurs Game 5 matchup, your $70 in total funds can be allocated across multiple outcomes. For example, if you trade $30 on the Knicks to win the championship at favorable odds, you keep your remaining $40 for other trades. If your Knicks trade wins, your payout increases your account balance. If it doesn't, you've still got funds remaining to trade on other markets or events.
