New traders who enter the Kalshi referral code ACTION at sign-up and trade $25 get up to a $500 trading credit. Tonight's Mariners vs. Yankees game at Yankee Stadium gives that credit an obvious first home, with first pitch at 7:05 p.m. ET on TBS.
Kalshi operates as a CFTC regulated exchange. You buy event contracts priced from $0.01 to $0.99 rather than taking a sportsbook number. The Kalshi referral code ACTION and promo code field mean the same thing at registration, so type ACTION either way.
What Does the Kalshi Referral Code ACTION Deliver?
| Detail | Terms |
|---|---|
| Referral code | ACTION |
| Offer | Trade $25, get up to a $500 trading credit |

Read the credit range row twice. Kalshi randomizes the award across five tiers, and roughly seven in ten new accounts land at $15. The $500 top tier reaches well under one percent of traders. Treat $15 as the realistic outcome and the ceiling as the lottery ticket.
How Do You Claim Kalshi Referral Code ACTION?
- Tap through to Kalshi and open a new account.
- Enter ACTION in the promo or referral field during registration.
- Clear identity verification with a government ID and a selfie.
- Deposit at least $10.
- Trade $25 in total volume on any MLB market. Losing trades count the same as winners.
Traders who blow past the field at registration sometimes still add the Kalshi promo code ACTION afterward, provided they hold off on that first qualifying trade.
What Happens After You Trade $25? My Own Run Through
I ran this exact sequence for myself, and verification took under three minutes and my ID photo cleared on the first attempt. The debit deposit settled instantly.
I bought 40 contracts on an afternoon MLB game at $0.62, which cleared the $25 threshold in a single order. My credit hit the portfolio about 90 seconds after the fill: $15, the common tier.
Two details worth noting are that bonus credit sits apart from your cash balance until you trade an amount equal to it, so it reads like money you do not own yet. And the seven- day clock you have to use your funds moves faster than the timeline given by other prediction market apps.
Set a reminder the moment the credit lands, and fund the account only when you have a week of games in front of you. Anyone claiming the Kalshi referral code ACTION benefits from that one habit more than any other.
What Is the Best Kalshi Trade on Mariners vs. Yankees?
Tonight's starters for the Mariners and Yankees:
| Team | Starter | Wins | Losses | ERA |
|---|---|---|---|---|
| Seattle Mariners | Bryan Woo (RHP) | 8 | 8 | 4.31 |
| New York Yankees | Ryan Weathers (LHP) | 5 | 7 | 3.79 |
Seattle arrives at 56 wins and 63 losses. New York sits at 66 and 52 and holds home field. My Kalshi predictions:
- Yankees to win. The market prices New York near $0.55. Set a bid at $0.53 and let sellers come to you instead of paying up.
- Under the posted total near $0.52 as a second angle. Woo misses bats and Weathers owns the sharper ERA of the two.
- Check prices at 7:00 p.m. ET. Contracts move until the umpire calls play, and lineup news swings a total by two or three cents.
A $0.53 contract stretches $25 across roughly 47 contracts. Each one settles at $1.00 or $0.00, so a winning side returns about $47. The Kalshi referral code ACTION puts a credit behind whichever side you land on.
Is the Kalshi Promo Code ACTION Legitimate?
Yes. Kalshi holds designated contract market status with the CFTC, which places it under federal oversight rather than state sportsbook licensing. The Kalshi promo code ACTION unlocks the current welcome offer for new accounts.
Which States Miss Out?
AZ, IL, MA, MD, MI, MT, NV, OH and WA sit outside one of the top prediction market promos in North America. New users 18 and older everywhere else qualify. Kalshi checks your location during registration and shows only the markets open to you, which settles the question faster than any list.
Enter the Kalshi referral code ACTION before 7:05 p.m. ET this evening and put the credit to work on Mariners vs. Yankees.
