How active is this market?

$816K in lifetime turnover and $3.1M of resting liquidity puts this market in the top 2% by volume for sports contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.

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.

Key terms

YES / NO share

A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.

CLOB

Central limit order book — the matching engine that pairs YES buyers with NO buyers. Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.

UMA optimistic oracle

The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.

Slippage

The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
