Polymarket esports prices, matched.
Polymarket lists CS2, League of Legends and UFC markets by its own event slugs and team names. We link every event to the real match, turn the prices to that match's team1 and team2, and serve them as decimal odds with liquidity, spread and full line movement next to the live score.

The part of the Polymarket API you would have to build
Polymarket's own API gives you markets. Using them for esports means finding which real match each one is, which side is which, and when a market stops being a price. That is what this does.
Linked to the match
Each event is matched to our fixture by team identity and time, re-checked every 15 minutes.
Sides turned for you
Prices follow the match's own team1/team2, whatever order the market lists them in.
Every LoL market
Series, game winners, handicap, first blood, kills, objectives and multikills.
Book depth
Liquidity, volume, best bid, best ask and spread on every row.
No fake prices
Untraded markets read illiquid with no price; decided ones read suspended.
Closing lines
Finished matches keep their last pre-match price and the full movement.
How are Polymarket events linked to matches?
Every event is matched to our fixture from the teams' provider IDs and the start time, with a probabilistic matcher for teams it has not seen before. Resolved markets are checked against the real winner. Each link is re-checked every 15 minutes, so a rescheduled or re-paired match never keeps another match's odds.
Polymarket's listed start times can be off: three Worlds 2026 matches were listed a day away from the official schedule. Our match row always carries the official time.
