Here is how the Polymarket and Kalshi codes compare:PolymarketKalshiVerified codesCUSE, SILIVE, OREGON, MASS, CLEVESYRACUSE, SILIVE, OREGONLIVE1, MASSLIVE1, CLEVELANDBonus$50 on a $10 deposit ($60 total)$25 on a $25 deposit ($50 total)Minimum to qualify$10 deposit$25 depositPlatform typePeer-to-peer prediction marketCFTC-regulated exchangePrices set byTrader supply and demandTrader limit orders (order book)The difference comes down to mechanics. Polymarket’s peer-to-peer structure means prices move on trader sentiment, which tends to produce faster price discovery and deeper volume on big boards like tonight’s game. Kalshi runs as a CFTC-regulated exchange with an order book. On entry cost the gap is real—Polymarket asks $10 to open with $60, Kalshi asks $25 to open with $50—but many traders open both, using a Polymarket referral code and a Kalshi promo code, to compare Polymarket odds against Kalshi odds before committing funds.Do the Polymarket and Kalshi codes work as referral codes?Yes. On both platforms the same string works as an referral code, a promo code, or a referral code—there is no separate code for each label. The Polymarket referral codes are the same five strings as the referral and promo codes: CUSE, SILIVE, OREGON, MASS, and CLEVE. The Kalshi referral codes are SYRACUSE, SILIVE, OREGONLIVE1, MASSLIVE1, and CLEVELAND. Whichever field it lands in at sign-up, entering a verified code unlocks the same bonus—$60 total on Polymarket, $50 total on Kalshi.Are Polymarket and Kalshi legal in the US?Yes. Kalshi is a CFTC-regulated prediction market exchange available across the United States, and Polymarket is a prediction market open to US users. Neither is a sportsbook. Instead of a house setting lines, you buy and sell contracts on event outcomes for a price between $0.01 and $0.99, and the market price reflects the probability of each outcome—which is why tonight’s game is quoted in cents and percentages. That structure is why both platforms are accessible in many states where traditional online sports betting is not, and why a Polymarket referral code or Kalshi promo code is open to most new US users.All verified Polymarket and Kalshi codes for Monday Night Football Week 1:To recap, all ten codes are confirmed active as of Monday, September 14, 2026.
