What the contract measures

The supplied source describes a tennis match, Sergio Callejon Hernando vs Luca Castagnola, in the M15 Monastir Main Draw, "originally scheduled for October 16, 2026 at 6:00AM ET" [1]. The winner market resolves to the player who advances. If the match is canceled or not played, ends in a tie, or has no determined winner by October 30, 2026, 11:59 PM ET, it resolves to 50-50. A walkover also resolves to 50-50, while a retirement, default, or disqualification after the match begins resolves to the player who advances [1]. The primary resolution source is official ITF information, and "a consensus of credible reporting may also be used" [1].

The event lists a close time of 2026-10-23T10:00:00.000Z [1]. That is a listed end time in the contract data, not a confirmed match date or a resolution date.

Reading the snapshot

The three saved Polymarket markets were observed at 2026-10-16T03:00:06.094Z and retrieved at 2026-10-16T04:14:57.661Z [1]. These prices describe that earlier observation, not live conditions at the time you read this.

In the winner market, Sergio Callejon Hernando is priced at 0.835 and Luca Castagnola at 0.165 [1]. The two set handicap markets are separate contracts. One lists Sergio Callejon Hernando (-1.5) at 0.62 and Luca Castagnola (+1.5) at 0.38. The other lists Luca Castagnola (-1.5) at 0.115 and Sergio Callejon Hernando (+1.5) at 0.885 [1]. Because the handicap contracts have different wording from the winner market, their prices should not be read as the same question. The supplied excerpt does not include the full settlement rules for the handicap markets, so I cannot confirm how they settle.

Prices here are snapshots, not executable quotes or verified probabilities. The supplied data does not include volume or liquidity figures, so no conclusions about depth are possible.

What remains uncertain

The sample includes all three saved markets for this single event (partialSample is false) [1]. The source also notes that this "does not establish that the providers list every possible real-world outcome" [1]. Only one platform appears in the evidence, so there is no cross-platform comparison.

The evidence does not explain why prices are where they are, and it contains no news, trader counts, or result information. Whether the match is played on schedule is also outside the supplied evidence.
