Snapshot observed 2026-10-19T06:00:06.076Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

The supplied snapshot covers one provider event on Polymarket: "Deportivo Saprissa vs. LD Alajuelense - More Markets." The source describes it as "More markets for the Liga Promerica game, scheduled for October 31 at 10:00 PM ET." [1] The included contracts differ in type. Some are full-match Over/Under lines at 0.5, 1.5, 2.5, 3.5, 4.5 and 5.5. Others are first-half lines, including match-wide, Deportivo Saprissa, and LD Alajuelense versions, and one is a spread on "LD Alajuelense (-1.5)" [1]. Each contract has its own title and wording, so each should be read on its own terms.

The listed end time for these markets is 2026-11-01T02:00:00.000Z [1]. This is a closing time in the contract data. It does not show the match result, and the evidence does not include any resolution outcome.

Reading the snapshot

The provider observation time is 2026-10-19T06:00:06.076Z, and the source was retrieved at 2026-10-19T07:54:20.427Z [1]. These prices describe that earlier observation. They do not describe live conditions when you read this.

In the snapshot, the full-match Over/Under 0.5 and 2.5 lines show Over at 0.51 and Under at 0.49 [1]. The 1.5, 3.5, 4.5 and 5.5 lines show 0.50 for each side [1]. The spread shows LD Alajuelense at 0.495 and Deportivo Saprissa at 0.505 [1]. These are snapshot prices, not executable quotes or verified probabilities. A gap of 0.01 is small and should not be read as a meaningful signal.

Compare prices only between contracts with the same wording. A first-half line and a full-match line are different contracts, so their prices should not be averaged or ranked together.

What remains uncertain

The sample is partial. Polymarket lists 46 markets for this event, and 12 are included [1]. Markets were selected by Yes price descending, then volume. The 34 omitted markets are not shown, so their prices are unknown, and the omitted set should not be assumed to be priced lower. The evidence does not include volume, trader counts, or liquidity, so it cannot show how deep any market is.

The evidence does not explain why prices are where they are, and it contains no news. It includes no prices from other platforms, so no cross-platform comparison is possible. A price difference between two contracts is not, by itself, an arbitrage opportunity.
