What to know

  • Polymarket rolled out three regional promo codes (CLEVE, MASS, OREGON) across September 22–23, 2026, each offering $50 bonuses on $10 deposits for new US customers.
  • Codes are time-limited to specific MLB matchups and must be entered at account creation; bonus funds are usable across all Polymarket markets beyond sports betting.
  • The promotion positions Polymarket competitively against Kalshi and DraftKings, claiming to offer the lowest entry cost and no minimum trading volume requirements.

“On Tuesday, Sept. 22, eligible first-time U.S. customers can turn a qualifying $10 deposit into $60 in starting funds after Polymarket updates promo code OREGON.”
