“Will William Byron win the NASCAR Quaker State 400?” is a prediction market on Polymarket with two tradeable outcomes, Yes and No. It belongs to the event “NASCAR: Quaker State 400”. The Yes price is the market's implied probability that the question resolves Yes. Quotes can change as orders are updated or filled; a quoted price does not guarantee an available fill at that price.
The venue reports this market as closed. Its scheduled close is Jun 29, 2025. No resolved outcome is inferred from a closed or suspended state.

Each figure carries its observation time; nothing here is a return forecast.

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.
Hourly closes of the Yes price. 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.
