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.
