Claim the Polymarket Referral Code for Dodgers vs. Braves NLDS Game 4
New users can activate the Polymarket referral code SIBONUS before trading on Wednesday's Dodgers vs. Braves NLDS Game 4. A code is required to unlock this welcome offer, and SIBONUS must be entered during sign-up to trigger the $25 trading bonus once the account is funded and a trade is placed.
The terms are straightforward but worth reviewing before placing a first trade:
- Deposit at least $10 to qualify for the bonus.
- Enter the Polymarket promo code SIBONUS during registration.
- Verify identity with a government-issued ID and a matching selfie.
- Complete one real-money trade on an eligible market to unlock the $25 bonus.
- Meet a 1x playthrough requirement before withdrawing any profits.
For example, a trader could place $10 on the Dodgers to win Game 4 and advance to the NLCS. If that outcome hits, the trader collects the payout from the market along with the unlocked bonus funds to use on future trades. If the Braves instead force a Game 5, the initial trade would result in a loss, but the $25 bonus remains available to use on another eligible market.
Use the Polymarket promo code SIBONUS carefully, since it cannot be applied retroactively once an account has already been created. Bettors who also want to compare offers across platforms should check out this list of best prediction market promos before deciding where to place their first trade. Those referencing bonus code COVERS for editorial tracking can do so without affecting the SIBONUS offer terms.
