Polymarket Promo Code vs. Kalshi Promo Code vs. DraftKings Promo Code: Which Bonus Is Best Right Now?
Three of the biggest names in US event markets and sports are running new-customer promotions into Mariners vs. Astros:
| Polymarket | Kalshi | DraftKings | |
|---|---|---|---|
| Code | OREGON | OREGONLIVE55 | No actual 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 |

| Minimum to qualify | $10 deposit | $25 deposit | $5 first bet |
The Polymarket promo code OREGON is the cheapest entry of the three: $10 gets you $60 in trading funds, with no minimum trading volume to unlock it. The Kalshi promo code OREGONLIVE55 and Kalshi referral code OREGONLIVE55 point to an upgraded deposit match—$55 in bonus funds on a $25 deposit, for $80 total, running for a limited time with no announced end date. DraftKings is a licensed sportsbook where the reward pays out in non-withdrawable bonus bets—signing up with this DraftKings promo code unlocks Spend $5, Get $150 in Bonuses on a $5 first bet.

Do You Need a DraftKings Promo Code to Claim the Bonus?
No—one of the most common misconceptions among new users. DraftKings does not require a DraftKings 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 entered at sign-up, or the $50 bonus is not granted.
