Polymarket rolls out multiple $50 bonus codes for U.S. sports prediction markets

Polymarket, the U.S.-legal peer‑to‑peer prediction market, is offering a $50 trading bonus to new users who deposit $20. The promotion is available through several invite or promo codes—including LABS, CUSE, MASS and SILIVE—each linked to upcoming sports events such as MLB games, the UFC Holloway vs. McGregor bout, the Scottish Open golf tournament, and a slate of WNBA matchups. All codes grant the same $50 credit with no rollover or first‑bet condition, instantly adding to a $70 starting balance that can be used on any open Polymarket market, from sports to politics and crypto. Eligibility is limited to new U.S. accounts, one bonus per user, and requires standard identity verification. The offers are active across more than 40 U.S. states and are tied to specific event windows, for example the LABS code is tied to Tuesday night MLB games, while CUSE and MASS are extended through the Scottish Open weekend. Polymarket describes its platform as a stock‑market‑style exchange where traders buy and sell positions on real‑world outcomes, with prices updating in real time based on collective trader sentiment.
