Kalshi Promo Code ACTION: How to Trade Celtics vs. Cavaliers
Use the Kalshi promo code ACTION during registration to be enrolled in a $10 new user promo. This is a buy-low welcome offer, as just $10 in trades are required to unlock $10 in bonus cash. Your first $10 in trades can come off any prediction market, which includes NBA games this evening.
The Celtics vs. Cavaliers is the headlining game of the day, as these are two of the top three teams in the Eastern Conference. Now that Jayson Tatum has returned to the lineup for Boston, the Cavaliers are going to have a big uphill battle. Here are some Kalshi NBA prediction markets to trade on:
- Game winner
- Point differential
- Total points
- Player statistics
Of all the Kalshi prediction markets available, I like Boston over 109.5 total points scored YES. Between Tatum, Jaylen Brown and the rest of the talent on this roster, it's hard to envision a poor offensive showing from one of the league's best scoring teams.
