New York Knicks +111 45.5%

If you choose to use your $50 Polymarket sign-up bonus on the moneyline, your potential payouts will vary based on your prediction. Backing the favored Cavaliers (-131) with your $50 stake would yield approximately $38.17 in profit if Cleveland defends its home court. Alternatively, if you predict an upset and wager the $50 bonus on the underdog Knicks (+111), a winning ticket would return a higher profit of $55.50.

When looking for the better bet, 2025 postseason statistics paint a distinct picture in favor of the road underdogs. The New York Knicks have been overwhelmingly dominant, boasting an exceptional 18.0 Net Rate compared to Cleveland’s marginal 1.2 Net Rate. New York also commands the glass with a 55.3% Total Rebound Percentage, comfortably outpacing the Cavaliers’ 50.6%. Even though they are priced at plus-money, the Knicks’ underlying metrics suggest they are a formidable threat to win outright.
