NBA Prediction Market Apps: Get Top Bonuses For Oct. 23 Games
By Ryan Bologna in Sports Betting News
Published:
The NBA returned this week, and we have a loaded Friday night slate for new users to capitalize on with the top prediction market apps. Whether you are trading on the Knicks vs. Boston headlining game, or pivoting to the rest of the slate, prediction markets are a great way to gear up for the first tip-off.
Prediction markets are different from a normal sportsbook. The absence of a vig stands out, and that increases the payout for any position you take. You also have the chance to buy and sell your positions until the final buzzer.
Here are the five best prediction market platforms for New York vs. Boston, and the offer at each right now.
Offers and availability vary by state and are subject to each platform’s terms.

Use Prediction Markets for New York Knicks vs. Boston Celtics Tonight
Both squads enter this matchup seeking their first win after 0-1 starts. The Celtics put up 113 points in their first game against the Pistons, compared to New York’s 100 against the 76ers. Both teams are looking for their first win on the season after losing on opening night.
The Knicks arrive fully healthy, while the Celtics are only missing guard Devin Carter due to illness, leaving both primary rotations for these Eastern Conference heavyweights firmly intact and minimizing major market adjustments.
The Celtics will look for Jayson Tatum to rebound, as his shooting struggles heavily contributed to the team wasting an impressive debut for Paul George. The Knicks turned in an all-around disappointing performance on opening night after receiving their championship rings. The offense will look to click like it did in last year’s postseason to help them get their first victory.
Other games that stand out tonight are Mavericks vs. Pacers, Timberwolves vs. Magic, Pistons vs. Heat and Rockets vs. Spurs. You can trade on any of these games with each of the offers we outlined on this page.
How To Claim These Offers Before Tipoff

- Sign up and verify your identity.
- Confirm the offer is active in your state.
- Make the qualifying deposit or trade.
- Find this NBA market and place your trade.
Prediction markets carry real financial risk, so only trade what you can afford to lose before tipoff; availability, minimum age, and bonus terms differ by platform and jurisdiction.
