How the Polymarket Promo Code Works for MLB Playoff Trading
New users can activate the Polymarket promo code SIBONUS by signing up through a verified link, verifying identity, and depositing at least $10. Once the deposit clears, Polymarket credits a $25 trading bonus that can be applied to markets tied to Wednesday's MLB Division Series matchups, including Cleveland at Chicago, Los Angeles vs. Atlanta, Tampa Bay at New York, and Milwaukee vs. San Diego.
- Available in every state except Nevada
- Requires proof of identification during registration
- Minimum deposit of $10 to trigger the bonus
- Bonus funds carry a 1x playthrough requirement before withdrawal
Consider a trade placed on whether Cleveland forces a Game 4 against Chicago. If that outcome resolves in the trader's favor, the position pays out based on the market odds at the time of the trade, and once the 1x playthrough is met, any profit becomes available to withdraw. If the position does not resolve favorably, the trader's exposure is limited to the funds used from the bonus and deposit, with nothing additional owed.
Users who want to keep earning through the platform can also look into the Polymarket referral code program, which rewards both the referring trader and the newly signed-up user. Code COVERS is embedded in several verified entry links as well, though SIBONUS remains the direct code for this specific welcome offer. For traders comparing options across the industry, reviewing the best prediction market promos can help identify which platform fits their trading habits before this week's playoff schedule continues.
