Kalshi, Polymarket and other platforms unveil up to $500 bonus promos for MLB betting

Kalshi promo code Polymarket bonus MLB betting sports betting promotion prediction market

Several U.S.-based prediction‑market and sportsbook platforms have launched new sign‑up promotions tied to Major League Baseball and other sports. Kalshi offers multiple promo codes – MLIVE, RATE, OREGONLIVE1 and SILIVE – that provide a variable bonus ranging from $15 to $500 when new users trade at least $25 on contract markets such as Michigan Wolverines football futures, MLB trade‑deadline games or the Yankees‑Phillies matchup. The bonus credits are awarded as trading funds and cannot be withdrawn directly.

Polymarket introduced several invite codes – ALCOM, ELITE, CUSE, MASS and others – that grant new traders a $20‑$50 bonus after a $10‑$20 initial deposit. These offers apply to MLB games (e.g., 3M Open, Yankees‑Phillies), PGA events and even non‑sports markets. Bet365 runs a "Bet $10, Get $150/365" bonus depending on the state, while Betr’s WTOP code gives new users two $100 entries (up to $200 total) that are refunded as Betr Bucks if the picks lose. All promotions require users to be 18 or older, located in eligible U.S. states (or Canada for one Polymarket offer), and to complete identity verification.
