Kalshi promo code ACTION gives new traders a tiered welcome bonus worth between $15 and $500 in total value. The qualification path is short: register a new account, verify your identity, deposit at least $10, and trade $25 in event contracts.
The bonus tier is randomized rather than fixed, and the $15 rung lands on roughly 70% of new accounts, so treat $500 as the ceiling and $15 as your realistic expectation.
Philadelphia visits St. Louis tonight at 7:45 p.m. ET on FS1 from Busch Stadium, which makes the Phillies vs. Cardinals moneyline the cleanest way to clear the $25 requirement in a single position.
Kalshi is a CFTC-regulated derivatives exchange where you buy and sell event contracts. You trade against other users on an order book rather than against a house, meaning Phillies vs. Cardinals prices are eligible to move on volume alone.

|---|---|

How Do You Claim Kalshi Promo Code ACTION?
- Tap any Claim Offer button on this page.
- Register a new account and verify your identity.
- Enter ACTION in the promo code field when prompted.
- Deposit at least $10.
- Trade $25 on MLB today. Kalshi then drops the bonus into your balance.
Kalshi asks for volume, not winners. Losing trades still count toward the $25 threshold. Spread your $25 across several small Kalshi predictions positions or dump it on one contract. The choice is yours.
What Happened When I Signed Up With Kalshi?
Here's my own run-through with the Kalshi promo code ACTION, start to bonus:
- Sign-up: I typed ACTION into the referral field and funded the account with a $25 deposit.
- Verification: Under three minutes, start to finish, on my phone.
- First trade: 14 "Yes" contracts on Phillies MLB odds at 41¢, placed yesterday.
- Settled volume: $26.10 — just past the $25 threshold.
- Bonus posted: $35 the next morning, one rung above the floor.
Two things that session taught me:
- The clock runs fast. The bonus expires seven days after Kalshi credits it, so I spent mine the same day on more MLB prediction markets.
- The order book moves like an exchange, not a sportsbook. My Wild Card price drifted four cents in an hour on volume alone. That volatility rewards patience and punishes panic.
How Do You Trade Phillies vs. Cardinals on Kalshi?
Tonight's pitching matchup gives the market plenty to chew on. Rookie right-hander Andrew Painter (1-8, 6.48 ERA) carries the ball for Philadelphia against Hunter Dobbins (2-2, 3.60 ERA). Philadelphia holds a 3.5-game cushion over St. Louis for the final NL Wild Card spot, so both clubs treat this series as a swing.
Three markets worth a look once you enroll in one of the top MLB prediction market apps:
- Game winner — the cleanest first trade for a $25 threshold.
- Total runs — both teams rank among the league's heaviest Under sides this season.
- Jordan Walker home run — the 2026 Home Run Derby champion snapped a month-long drought Saturday and enters on a nine-game hit streak.
Kalshi Promo Code ACTION or Kalshi Referral Code ACTION?
Both phrases point to the same thing. Kalshi labels the sign-up field a referral field, so plenty of traders search for the Kalshi referral code ACTION instead. Type ACTION into that box and the same tiered bonus applies.
One live account per person qualifies for the Kalshi referral code ACTION. Existing users fall outside it.
Kalshi Welcome Bonus and Event Contract FAQs
How does the Kalshi promo code ACTION work?
Kalshi credits a randomized tiered bonus after a new account trades $25 in event contracts. The five rungs are $15 (about 70% of accounts), $35 (24%), $75 (5%), $100 (0.65%), and $500 (0.35%).
Minimum deposit is $10, one live account per person qualifies, and the credit expires seven days after Kalshi posts it to your balance.
What are event contracts?
An event contract is a binary derivative that pays $1 if a stated outcome happens and $0 if it doesn't. Prices trade between 1¢ and 99¢, and the price roughly equals the market's implied probability.
A contract at 41¢ implies a 41% chance. Kalshi lists them on a CFTC-regulated designated contract market, so they are legally classified as swaps rather than wagers.
Is Kalshi legal in Delaware?
Yes, Kalshi currently accepts Delaware traders. Kalshi remains unavailable in AZ, IL, MA, MD, MI, MT, NV, OH and WA.
How do Kalshi odds compare to sportsbook odds?
Kalshi prices are stated in cents of implied probability, while sportsbooks quote American odds with a hold built into the line. A 41¢ Yes contract is comparable to roughly +144.
Because Kalshi's Yes and No prices sum close to 100¢ and its cost sits in a separate trading fee rather than inside the price, the effective margin is often thinner than a two-way moneyline. But this varies by market and liquidity, so compare each line individually.
Certain limitations apply. The offer is available to new users only, subject to the terms and conditions at kalshi.com/tc/500. 18+ only. Restrictions and eligibility requirements apply.
