Polymarket vs. Kalshi vs. DraftKings: Which Bonus is Best?
Three of the biggest names in US event markets and sports betting are running competitive new-customer promotions ahead of Mariners vs. Astros. Understanding the differences between a peer-to-peer prediction market, an exchange-style market, and a traditional sportsbook is key to choosing the right offer.
| Feature | Polymarket | Kalshi | DraftKings |
|---|---|---|---|
| Code | OREGON | OREGONLIVE55 | No promo code required |
| Current Offer | $50 bonus on a $10 deposit | $55 bonus on a $25 deposit ($80 total), limited time | Spend $5, Get $150 in Bonuses |
| Platform Type | Peer-to-peer prediction market | Exchange-style prediction market | Licensed sportsbook |
| Prices Set By | Trader supply and demand | User limit orders | Oddsmakers |
| MLB Coverage | Yes | Yes | Yes |
| Politics Markets | Yes | Yes | No |
| Minimum to Qualify | $10 deposit | $25 deposit | $5 first bet |
The Polymarket promo code OREGON stands out as the cheapest entry point of the three: a $10 deposit gets you $60 in trading funds, with no minimum trading volume required to unlock the bonus. Meanwhile, the Kalshi promo code OREGONLIVE55 points to an upgraded deposit match—$55 in bonus funds on a $25 deposit, for $80 total, running for a limited time. DraftKings operates as a licensed sportsbook where the reward pays out in non-withdrawable bonus bets, unlocking a “Spend $5, Get $150 in Bonuses” offer on a $5 first bet. For Mariners vs. Astros, Polymarket MLB markets carry the deepest prop and derivative coverage, and Polymarket odds move fastest on lineup news, making the OREGON code the strongest option for a single-game board.
Do You Need a DraftKings Promo Code?
No, and this is one of the most common misconceptions among new users. DraftKings does not require a promo code at registration. The DraftKings bonus 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 OREGON must be manually entered at sign-up, or the $50 bonus will not be granted.
