What the contract measures

The saved Polymarket event covers total corners markets for a Club Friendlies game between Chelsea FC and Real Sociedad San Sebastian, described as "scheduled for August 15, 2026 at 9:00 AM ET" [1]. Three contracts are included, and their wording differs. One asks whether Chelsea FC will record over or under 4.5 corners. Another asks whether the total corners will be odd or even. The third asks which team will take the first corner [1]. All three list the same end time, 2026-08-15T13:00:00.000Z [1]. Because they ask different questions, their prices should be read separately rather than treated as one measure.

Reading the snapshot

The event was observed at 2026-10-17T09:00:05.996Z and retrieved at 2026-10-17T09:45:54.024Z [1]. These are provider and retrieval times, not the time the match was played. In this snapshot, every listed outcome is priced at 0.5, including Over and Under, Odd and Even, and both team outcomes [1]. These are observed prices, not executable quotes or verified probabilities. The evidence includes no volume or trader counts, so it cannot describe liquidity or how many participants hold each side.

What remains uncertain

The sample covers all three saved markets for this event, and the partial sample flag is false [1]. The source still states that the sample "does not establish that the providers list every possible real-world outcome" [1]. The evidence does not show whether these contracts have resolved or what the match outcomes were. The listed end time falls before the retrieval date, so the prices should be read as a record of a past snapshot, not a current market reading. The evidence also gives no explanation for the equal 0.5 values, and equal prices across different contracts do not by themselves indicate an arbitrage opportunity.
