Polymarket Incentivises New Users with $20 Bonus for MLB Trading Activity
New users can claim a $20 bonus using promo code FOX, coinciding with key matchups including the Cubs-White Sox Crosstown Classic and the Dodgers-Rockies series.
Polymarket has launched a promotional initiative offering a $20 bonus to new users who engage in trading activity on Major League Baseball games. The offer, accessible via the promo code FOX, is timed to coincide with the Monday MLB slate, aiming to drive user acquisition within the prediction market sector.
The promotion targets new registrants on the platform, allowing them to trade on outcomes related to specific baseball matches. According to the source material, the bonus is contingent upon the user entering the designated code during the sign-up or trading process. Full terms and conditions for the offer are available through the platform’s dedicated promo code page.
The current promotional window aligns with a schedule featuring several high-profile matchups. The Chicago Cubs and Chicago White Sox are set to meet in the Crosstown Classic, with Shota Imanaga starting for the Cubs. The game is scheduled for 8:05 PM ET.
Other highlighted fixtures include the Los Angeles Dodgers facing the Colorado Rockies at Coors Field, where Blake Snell is expected to start. The San Diego Padres will take on the New York Mets at Citi Field, with Walker Buehler pitching against Nolan McLean. Additional markets include the Arizona Diamondbacks visiting the Boston Red Sox, and the Atlanta Braves playing the Minnesota Twins.
Polymarket operates as a prediction market platform where users trade on the outcomes of various events. The source notes that probabilities for these markets are subject to change. The promotion is distinct from other sports betting offers, such as a separate $50 bonus from Underdog Sportsbook, and focuses specifically on the trading mechanics of Polymarket’s interface.
The release of this promotion comes as the 2026 MLB season progresses toward its conclusion. The playoff schedule has been announced, with the Wild Card Series commencing on 29 September and the potential World Series Game 7 scheduled for 31 October. Twelve teams will qualify for the postseason, with games broadcast on FOX and streamable via FOX One.
Fox Sports, the source of the report, discloses that it may receive compensation if users sign up or place wagers through affiliate links associated with the promotion. This financial arrangement is standard for media outlets covering sports betting and prediction market developments.
