Two are prediction markets; one is a sportsbook. Here is how they compare:PolymarketKalshiDraftKingsCodeCLEVECLEVELANDNo actual promo code requiredCurrent offer$20 sign up bonus on a $10 deposit$25 bonus after $25 in tradesBet $5, Get $150 in Bonus BetsPlatform typePeer-to-peer prediction marketExchange-style prediction marketLicensed sportsbookPrices set byTrader supply and demandUser limit ordersOddsmakersNFL coverageYesYesYesPolitics marketsYesYesNoMinimum to qualify$10 deposit$25 in trades$5 first betThe Polymarket promo code CLEVE is the cheapest entry of the three: $10 gets you $30 in trading funds, with no minimum trading volume to unlock it. The Kalshi promo code CLEVELAND and Kalshi referral code CLEVELAND both require $25 in completed trades before bonus credit is granted, and the reward is equivalent. DraftKings is a different product entirely. It is a licensed sportsbook where you place bets against posted lines rather than trading positions against other users, and its reward pays out in non-withdrawable bonus bets rather than trading funds. For readers who want both, signing up with this DraftKings promo code unlocks Bet $5, Get $150 in Bonus Bets on a $5 first bet.For NFL Week 1 specifically, Polymarket NFL markets carry the deepest volume of the three, and Polymarket NFL odds move fastest on breaking team news — which is what makes the Polymarket promo code CLEVE the strongest of the three heading into the opener.Do You Need a DraftKings Promo Code to Claim the $150 Bonus?No — and this is one of the most common misconceptions among new users. DraftKings does not require you to type a DraftKings promo code at registration. The $150 in bonus bets activates automatically when a new customer signs up through an eligible link and places a qualifying $5 bet. Polymarket works the opposite way: the Polymarket promo code CLEVE must be entered at sign-up, or the $20 Polymarket sign up bonus is not granted.More Verified Polymarket Promo Codes for NFL Week 1:The Polymarket promo code CLEVE is one of five verified Polymarket promo codes now extended into NFL Week 1 as of August 31, 2026.
