Resolution criteria on PolyGram: This market will resolve to “Over” if more than 5.5 games are played during the 2026 NBA Playoffs First Round series between the Toronto Raptors and Cleveland Cavaliers. Otherwise, this market will resolve to “Under”. If a partial series is played and not completed by May 31, 2026, 11:59 PM ET, this market will resolve according to the number of games played. If the 2026 NBA Playoffs are cancelled, postponed after May 31, 2026, 11:59 PM ET, or there is otherwise no winner declared within that timeframe, this market will resolve to 50-50. The resolution source for this market will be official information from the NBA; however, a consensus of credible reporting may also be used.

For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution.

Market outcomes
| NBA Playoffs: Raptors vs. Cavaliers Total Games O/U 5.5 | 100% YES | 0% NO |
The 2026 NBA Playoffs First Round matchup between the Toronto Raptors and Cleveland Cavaliers will determine whether their series extends beyond six games. The market currently reflects 100% implied probability for the Over, suggesting traders on Polymarket's order book are pricing in a seven-game series as near-certain. This extreme skew typically emerges when one outcome dominates positioning, though it warrants scrutiny given the settlement window closes 31 May 2026, creating a hard deadline for series completion.
First-round series outcomes in recent NBA history show considerable variance. Between 2020 and 2024, approximately 40% of matchups went the full seven games, whilst roughly 60% concluded in five or six games. The Raptors and Cavaliers' relative strength, injury status, and playoff experience will substantially influence series length. Both franchises have demonstrated competitive depth in recent seasons, though roster composition changes significantly year to year. The current 100% probability on the Over suggests the market has already priced in specific assumptions about team quality or matchup dynamics that favour extended play.
Traders should monitor roster announcements through the 2025–26 regular season, particularly regarding key player availability and injury reports as the playoffs approach. The NBA's playoff schedule and any potential postponements could affect whether games complete before the 31 May deadline. Recent precedent from 2024 playoffs showed that unexpected injuries or trades in the final weeks can shift series dynamics materially. The extreme probability reading leaves minimal room for the Under, suggesting limited value unless new information substantially alters expectations about competitive balance.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.

$6K in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for 2026 nba playoffs contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
As of today, traders on Polymarket price this outcome at 100%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.
