What are Sports markets?
Sports markets cover match winners, tournament winners, spreads, handicaps, player awards, and event props across football, soccer, basketball, tennis, baseball, esports, and other competitions.
How to bet on Sports markets
Check the event, start time, team names, injury news, and whether the market is about the winner, spread, or a specific stat. A good price is not useful if the market wording is not what you expected.
Outcome resolution
Sports markets usually settle from the official result or the source named in the rules. Some markets include overtime, while others settle at regulation time.
Fairness
Fairness depends on the rule details. Postponed games, abandoned matches, disqualifications, and stat corrections can all matter.
Key points
- Check whether overtime counts.
- Confirm the exact team or player.
- Watch liquidity near game time.
Unique resolution risks for Sports
Check final-score sources, cancellations, postponements, overtime, stat corrections and tournament-specific rules before relying on the displayed favorite.
Resolution examples to check
- A match-winner market may include overtime, while a regulation-time market settles after the scheduled period even if the game continues.
- A postponed match can remain open, settle at a replacement date, or be voided depending on the written postponement window.
- Player-stat markets may use an official league box score and can be affected by later stat corrections.
Frequently asked questions
Does overtime count in Polymarket sports markets?
Only when the market rules say it does. Match-winner and regulation-time markets can use different settlement periods for the same event.
What happens if a game is postponed?
The market-specific postponement and cancellation clauses control. Check the allowed rescheduling period before assuming the market will be voided.
