Cavaliers vs. Knicks Game 2: What's at Stake Thursday Night
Game 1 of the Eastern Conference finals delivered one of the most dramatic finishes of the 2025 playoffs, with the Knicks overcoming a 22-point deficit in the final 7:52 of regulation to win 115-104 in overtime. Jalen Brunson poured in 15 fourth-quarter points as New York closed regulation on a 30-8 run, and OG Anunoby added nine more in overtime to seal the victory. The win extended the Knicks' winning streak to eight games and gave them a commanding 1-0 series lead heading into Thursday's Game 2.
The Cavaliers, meanwhile, are no strangers to adversity in these playoffs. Cleveland needed all seven games to eliminate both the Toronto Raptors and the Detroit Pistons, and Donovan Mitchell -- who scored 29 points in Game 1 but just three during the Knicks' fourth-quarter surge -- made clear the team isn't rattled. "It's one loss," Mitchell said. "We have an opportunity to come back here in two days and steal one here." Whether the Cavaliers can respond with the resilience they've shown all postseason makes Game 2 a compelling market to trade on Polymarket.

How the Polymarket Promo Code $50 Bonus Works
New users can claim a $50 bonus by signing up with the Polymarket promo code COVERS and making a minimum deposit of $20. Unlike traditional sportsbook promotions, Polymarket operates as a prediction market, meaning you're trading on the probability of outcomes rather than placing standard wagers. For Game 2, you could trade on whether the Cavaliers win outright and bounce back, or whether the Knicks extend their dominant run and go up 2-0 -- if your position is correct, you profit based on the market price; if it moves against you, your position loses value accordingly.
Here are the key terms and conditions to keep in mind before claiming the offer:
- Available in all U.S. states except Nevada
- You must be physically located in an eligible state at the time of sign-up
- A minimum deposit of $20 is required to activate the $50 bonus
- Proof of ID is required, including a photo of a driver's license or passport and an accompanying selfie
- You may also be asked to verify your Social Security Number during registration
It's also worth noting that Polymarket extends well beyond sports, offering prediction markets on politics, economics, entertainment, climate, and more -- making it a uniquely versatile platform.
