Polymarket Promo Code SIBONUS: Get $20 Trading Bonus for MLB & WNBA on Wednesday
Wednesday, August 5 brings a full slate of baseball action and three focused WNBA matchups, making it the perfect day to explore Polymarket promo code offers. New users can claim a $20 bonus when they deposit $10 and enter promo code SIBONUS during registration. Whether you're interested in predicting outcomes across the MLB card or tracking the evening WNBA games, this welcome offer gives you additional trading capital to get started on the prediction market platform.
How the Polymarket Promo Code SIBONUS Works for Wednesday's Games
The Polymarket promo code SIBONUS unlocks a straightforward welcome offer: deposit $10 to receive a $20 trading bonus. This means you'll have $30 total in your account to trade on Wednesday's slate, which features marquee matchups like Blue Jays-Astros, Dodgers-Cubs, and Cardinals-Yankees alongside the evening WNBA action. The bonus applies to all eligible trades on the platform, allowing you to predict outcomes across any of these games.
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
- Promo code SIBONUS must be entered during registration
- A minimum deposit of $10 is required to activate the bonus
- Photo ID verification (driver's license or passport) and a selfie holding that ID are required
- The offer is available as of Wednesday, August 5
For example, if you predict the Dodgers will beat the Cubs and your trade wins, your $20 bonus plus any winnings would be added to your account. Conversely, if your prediction doesn't come through, you'd lose the bonus amount on that particular trade, but you still have your original $10 deposit to continue trading on other games throughout the evening.

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 betting analyst 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.
