What Did I Notice When Using Kalshi Promo Code LABS?
I redeemed code LABS on my iPhone during the World Cup, and registration flow took me roughly five minutes. Compared to other prediction market apps I had accounts with, this sign-up process ranked on the quicker end of the spectrum.
Kalshi asked for a photo of my driver’s license, cleared it inside a minute, and accepted a $50 debit deposit on the spot. I bought 40 contracts at 62 cents on an MLB game winner market, and the bonus credit hit my balance that same night.

Which Mariners vs. Yankees Markets Suit the Kalshi Promo Code MLB Bonus?
| Team | Starter | 2026 line |
|---|---|---|
| Seattle | Bryce Miller (RHP) | 4 wins, 6 losses, 3.08 ERA, 79 K |
| New York | W. Warren (RHP) | 8 wins, 6 losses, 4.18 ERA, 114 K |
Here is a look at a menu of Kalshi predictions to consider trading your first $25 on today:
- Game winner: the cleanest entry point tonight
- Series winner: hold one position across the full three game set
- AL East and AL pennant: longer horizon contracts that track the standings
- World Series: full season exposure at shifting prices
It’s important to keep context in mind that moves those prices:
- New York leads MLB in team ERA and ranks second amongst MLB lineups in home runs.
- Seattle sits last in runs and batting average, plus possess one of the worst road records in baseball.
- Ben Rice paces the Yankees in home runs and RBI as Aaron Judge remains on the DL.
- Confirmed lineups post about an hour before first pitch, so price the game winner contract after they drop.

Why Do MLB Traders Choose Kalshi?
While Kalshi appealed to me since it had one of the highest ceilings of prediction market promos, there were other features that stood out to me as well.
- Kalshi is a CFTC regulated exchange that backs every market.
- You trade against other traders instead of a house line.
- Each contract settles between $0 and $1, so your maximum risk stays visible from entry.
- Exits stay open right up to settlement, which suits in game price swings.
