Wednesday, October 7 brings four critical MLB Playoffs Divisional Series matchups, and it's the perfect time to explore prediction market promos. The $25 trading bonus from Polymarket requires the Polymarket promo code SIBONUS and a $10 deposit to unlock. You can trade on any of the four playoff games scheduled for Wednesday, making this an ideal opportunity to claim your bonus while the action unfolds.

18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See http://polymarket.com/tos  for more information. The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated exchange and clearing organization.

How the Polymarket Promo Code SIBONUS Works for Playoff Trading

The Polymarket promo code SIBONUS unlocks a $25 trading bonus when you meet the offer requirements. You must deposit at least $10 to qualify, and the bonus becomes available after you complete your first real-money trade on any eligible market, including the MLB Playoffs games on Wednesday.

Here are the key terms and conditions you should know:

  • Available in all U.S. states except Nevada
  • You must be physically located in an eligible state to claim the offer
  • Enter code SIBONUS during registration to unlock the bonus
  • Proof of ID is required, including a photo of your driver's license or passport plus a selfie holding that ID
  • Minimum deposit of $10 to qualify
  • The bonus requires a 1x playthrough before you can withdraw profits

If you trade on Cleveland versus Chicago at 4 PM ET and your prediction proves correct, your winnings are yours to keep after meeting the playthrough requirement. If your trade doesn't go your way, you still have the $25 bonus to use on additional trades across the four playoff games scheduled for Wednesday or any other eligible market.

Ryan Hagen’s foray into sports betting started early. At just 14 years old, he sought out a lottery kiosk clerk with relaxed gambling mores and convinced the fella to sell him ‘Sport Select’ tickets, which were part of the original government sports betting program in his native Alberta. Now a sports betting specialist at Sports Illustrated, Ryan prefers to place his bets legally and has established himself as an authority in the sports betting industry. His roles have included lead writer, content editor, managing editor, and more. Ryan has written and edited hundreds of sportsbook reviews and countless news, analysis, and promotional pieces for some of the most prominent companies in the sports betting world. As someone who eats, sleeps, and breathes sports and sports betting, Ryan’s goal is to impart his unbiased betting knowledge to prospective bettors, allowing them to make informed decisions, whether that’s signing up for a sportsbook, mulling over a moneyline, or placing a prop bet. A prolific bettor himself, Ryan lives for the NFL season and believes that every Saturday night from September to February is akin to Christmas Eve. Ryan has a B.A. in Communications from Royal Roads University in Victoria, British Columbia. His work is widely published in the sports betting industry and in publications such as the Calgary Herald and Vancouver Magazine. Off the clock, he can be found traveling, searching for noodles, working on his golf swing, and managing his degenerate number of fantasy football teams.
