Polymarket Pushes $50 Invite Code for New U.S. Users as MLB Returns

Overview

• Polymarket confirmed that the invite code CUSE and several sister codes are active for new U.S. accounts during the mid‑July MLB return, with reporting updated between July 16th and July 18th showing the offer timed to high‑profile series such as Dodgers‑Yankees and Mets‑Phillies.
• To claim the $50 promotional credit users must enter the code during registration, complete identity verification, make a qualifying first deposit of $20, and the $50 posts after the deposit is approved; codes cannot be added after signup.
• The promotion is limited to eligible states including New York, California, Texas and others listed by Polymarket, and the company is distributing multiple verified $50 codes through affiliate partners that each carry the same bonus.
• Because Polymarket is a peer‑to‑peer exchange where traders buy and sell contracts with one another, the credited bonus funds can immediately add liquidity and move contract prices on MLB markets, unlike bets placed with a traditional sportsbook.
• The offer raises consumer‑protection and market‑integrity questions because the scale of its impact depends on strict residency and ID checks and on whether bonus‑funded accounts stay active after using or withdrawing promotional balances; competitors such as Kalshi are running smaller, state‑mapped credits that change the promotional landscape.
