How the Polymarket Sign Up Bonus Works
Deposit at least $10 with Polymarket sign up bonus ACTION and Polymarket awards the $25 trading bonus after the qualifying requirements are met. The Polymarket review covers the prediction market in more detail.
There is no requirement for your first position to win.
New York is included in the eligible-state list, while Ohio is not. That means eligible Knicks fans can claim the offer from home, but users physically located in Ohio cannot.
Polymarket operates as a CFTC-regulated exchange. Users trade event contracts with other participants rather than betting against a sportsbook.
Contracts on prediction market apps generally trade between 1¢ and 99¢ and settle at $1 if the selected outcome occurs or $0 if it does not. A Knicks contract around 65¢ therefore represents roughly a 65% market-implied probability of New York winning.
Positions can also be sold before settlement when sufficient liquidity is available.

New York is a clear favorite amongst NBA odds without being priced like a lock. The gap partly reflects the schedule, with the Knicks playing Milwaukee the night before this rematch.
Cavaliers vs. Knicks Prediction and Pick
New York controlled the first meeting. Jalen Brunson scored 31 points with nine assists in Saturday's 109-97 win, while Karl-Anthony Towns added 29 points and 13 rebounds. Donovan Mitchell answered with 37 points for Cleveland, but the Cavaliers did not get enough secondary scoring to keep pace.

The broader form of both teams also favors New York.
Cleveland has lost four of its last five and sits 1-4 on the road. New York, meanwhile, has won five of six after opening the season 0-3.
The schedule is the main reason for caution. The Knicks host Milwaukee on Tuesday before facing Cleveland Wednesday, putting New York on the second night of a back-to-back.
That likely helps explain why the Knicks are still trading around the mid-60s instead of much higher.
Injuries also need to be monitored. Josh Hart has dealt with right ankle soreness, while Cleveland has had Sam Merrill and Jaylon Tyson sidelined.
Still, New York gets home court and just demonstrated it can control this matchup on Cleveland's floor.
