With the Celtics visiting Cleveland this Sunday, users who sign up can earn a $10 sign-up bonus to use on prediction markets. The bonus funds are unlocked once a user has completed $10 in trades—cumulative across multiple contracts if you prefer—making it an ideal way to engage with the 1:00 PM ET start.
Accessibility is a key feature here, as Kalshi is available in all 50 states. To claim the offer, participants must be at least 18 years old and make a first-time deposit of at least $1.

Trade on Celtics-Cavs via Kalshi
The moneyline market for today’s matchup is incredibly tight, pricing this as a near coin-flip. The Cavaliers enter as slight home favorites, likely due to their impressive 8-1 run since they acquired Harden. However, the market is also reacting to the absence of Jarrett Allen (knee), which opens up the paint for Boston. The table below displays the current probabilities for each team to win outright.
| Team | Probability |
|---|---|
| Cleveland Cavaliers | 50% |
| Boston Celtics | 51% |
Because the prices are nearly even, the potential payouts for traders are similar on both sides, with the Celtics as the ever-so-slight favorite, but by a small margin.
From a value perspective, we have to look beyond just the headlines. While the “Tatum Returns” narrative is driving excitement, there is usually an efficiency dip when a star reintegrates into the lineup, especially on the road.
The market seems to be weighing Cleveland’s hot streak against Boston’s structural advantage, making this a prime spot for traders who can correctly identify which factor—momentum or metrics—will prevail.
