What the contract measures

The saved event is the Polymarket listing "Chicago Fire FC vs. Orlando City SC - Total Corners," which covers total corners markets for an MLS game "scheduled for October 28, 2026 at 8:30 PM ET" [1]. The sampled contracts are Over/Under lines with different thresholds and scopes. Some cover the full match, such as the 7.5, 8.5, 9.5, 10.5 and 11.5 total corners lines. Others cover a single half, such as the 1st Half and 2nd Half lines, or Chicago Fire FC alone, such as "Chicago Fire FC Over/Under 2.5 Corners" [1]. Because these titles measure different things, their prices should not be treated as one outcome.

Each sampled market lists an end time of 2026-10-29T00:30:00.000Z, and the provider status is recorded as active [1]. The listed end time is a scheduled close setting. It is not a record of a resolved result.

Reading the snapshot

The provider observation time is 2026-10-16T03:00:06.094Z, and the source was retrieved at 2026-10-16T05:59:06.451Z [1]. These timestamps describe this saved record, not a live feed.

The sample includes 12 of 23 markets in this event [1]. According to the selection note, markets were ordered by price and then by volume before the cutoff. The 11 omitted markets cannot be judged from this record, so the included set should not be read as the full field, and no conclusion should be drawn that omitted lines are priced lower.

Every included market is quoted near 0.50. The full-match 7.5 and 8.5 lines show Over at 0.505 and Under at 0.495. The 9.5, 10.5 and 11.5 lines show 0.50 for each side. The 1st Half 3.5, 4.5 and 5.5 lines and the 2nd Half 4.5 and 5.5 lines also show 0.50 for each side, while the 2nd Half 3.5 line shows 0.505 and 0.495 [1]. These are snapshot prices, not executable quotes or verified probabilities. The excerpt does not report trading depth, so liquidity cannot be assessed from it.

Small price differences between lines with different thresholds or scopes do not, on their own, indicate an arbitrage opportunity.

What remains uncertain

The evidence does not explain why prices sit where they do, how many traders are involved, or what the market looked like after the observation time. It also contains no result for the match and no information from other platforms, so no cross-platform comparison is possible.
