Market outcomes
| Abidjan 2: Massimo Giunta vs Constantin Bittoun Kouzmine | 100% YES | 0% NO |
Massimo Giunta and Constantin Bittoun Kouzmine are scheduled to meet in the Abidjan 2 tournament on 28 April 2026. The market is currently pricing this match at 100% implied probability for Giunta's advancement, reflecting either exceptional confidence in the Italian player's form or minimal liquidity on the order book at present. With settlement closing 7 May 2026, traders have roughly one week post-match to verify the outcome.
The 100% probability reading warrants scrutiny given typical ATP Challenger volatility. Giunta, an Italian professional, and Bittoun Kouzmine, a French-born player, operate at similar competitive levels on the secondary circuit. Comparable Challenger matches between unseeded or lower-ranked players rarely settle with such extreme certainty unless one competitor carries a substantial ranking advantage or recent form differential. The absence of meaningful counter-positions on Polymarket's order book likely explains the extreme skew rather than fundamental conviction about the match outcome.
Key variables for traders include confirmation of both players' participation as the April date approaches, any late withdrawals due to injury or scheduling conflicts, and surface conditions at the Abidjan venue. The seven-day grace period for delays provides some protection against postponements, though extended weather disruptions could still trigger a 50-50 resolution. Tournament draw confirmation and recent head-to-head records between these competitors should be cross-referenced against current market pricing before committing capital.
This market settles from the official outcome published at https://www.atptour.com/en/scores/current. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "Abidjan 2: Massimo Giunta vs Constantin Bittoun Kouzmine" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$6K in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for tennis 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.
