Polymarket promo – Polymarket is advertising a welcome offer for new customers: use the promo code WTOP and make an initial deposit of at least $20 to receive a $50 bonus. The promotion is tied to today’s sports betting slate, including multiple MLB matchups.

On a day crowded with baseball matchups, Polymarket’s new-customer offer is trying to make the first bet feel less risky.

The platform says new Polymarket customers can use the promo code WTOP ahead of today’s slate and, after making an initial deposit of at least $20, receive a $50 bonus. The offer is described as a welcome promotion, with the page showing a date last verified of June 4, 2026.

Polymarket frames the extra capital as betting flexibility for today’s scheduled games. listing the Kansas City Royals facing the Minnesota Twins as one of the featured MLB contests. It also points to other MLB games on the board throughout the week. including the Athletics battling the Chicago Cubs and the Pittsburgh Pirates facing the Houston Astros.

To qualify for the $50 bonus. Polymarket says users must be new customers. must successfully make an initial deposit of at least $20 into their newly created account. and must be 18 years of age or older. It also says users must be physically located in an eligible Polymarket state to participate in the promotion.

The promotion is paired with probabilities for several matchups shown for today’s slate. The page lists these implied win probabilities:

SF @ MIL — SF 37.3% / MIL 62.7%
TOR @ ATL — TOR 35.4% / ATL 64.6%
