This market refers to the tennis match between Alexander Ritschard and Sergi Perez Contri in the ITF MEN - SINGLES: M25 Oviedo (Spain), clay, originally scheduled for August 29, 2026 at 4:00AM ET. This market will resolve to "Over" if the total number of games completed in set 2 equals or exceeds 10. Otherwise, it will resolve to "Under." Any tiebreak in set 2 counts as one (1) game toward the total. If set 2 begins but is not completed, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. An outcome is considered determined if it would have been guaranteed had the set been played to completion using the minimum number of additional games required. For example, for a line of 9.5, if play stops with set 2 at 5-4, completing the set would have required at least 1 additional game, resulting in at least 10 games played, so "Over" would resolve as the winning outcome. If the match ends before set 2 is reached, this market will resolve 50-50. If the match is canceled before play begins, or play has not begun by September 12, 2026, 11:59 PM ET (14 days after the scheduled start), this market will also resolve 50-50. Resolution will be based on official ITF results.

The Yes price read as a chance. A share at 21.5¢ implies 21.5%, but fees, available depth and who participates can affect that price. A market price is not a calibrated forecast or a verdict.
Dollar value of shares that changed hands in the last 24 hours. High volume means the price is being tested by real money; low volume means a few trades can move it.
Reported dollars resting in the order book. The available size on your side, at the prices you would accept, determines what can fill. A large total alone does not guarantee an execution near the quoted price.
The gap between the best bid and the best ask. A tight spread makes entry and exit cheap; a wide spread is a cost paid on every round trip.
The wallets holding the most shares on each side, and how much of the loaded sample the largest ten control. Concentration shows whether a market is a crowd or a handful of large positions.
The public fills, newest first: which wallet bought or sold which outcome, at what price, and when. It is the market's own diary, and every wallet on it links to a trader profile.
Observed closes of the Yes price over the market's life. The range shows how sure or split the crowd has been; the move shows which way it has been changing its mind.
Trading stops at the close time. The outcome is then settled by the resolution source named in the rules. A closed market is not resolved until the venue reports it, so the two states are shown separately.
