Snapshot observed 2026-10-19T09:00:05.974Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

The contract resolves to the goalkeeper with the most clean sheets in the 2026-27 Serie A season. Only Serie A matches count, and clean sheets from cup competitions and European or international matches are excluded [1]. Ties go first to the official leader as determined by Serie A, then to the goalkeeper who conceded fewer goals, and finally to the goalkeeper whose listed last name comes first alphabetically [1]. The rules also say that if the season is canceled or not completed by June 14, 2027, the market resolves to "Other" [1]. That date is a rule condition, not an announced event date. The listed end time is 2027-06-15T03:59:00.000Z [1]. Listed close times and actual resolution are separate things, so a reader should not assume the market will resolve at that moment.

Reading the snapshot

The prices come from a snapshot observed at 2026-10-19T09:00:05.974Z and retrieved at 2026-10-19T10:03:58.780Z [1]. They describe that moment only. Each goalkeeper has a separate Yes and No contract. The highest included Yes price is 0.37 for Mike Maignan (Milan), followed by 0.252 for Edoardo Corvi (Parma) and 0.215 for Mile Svilar (Roma) [1]. The lowest included Yes price is 0.016 for David de Gea (Fiorentina) [1]. These figures are not executable quotes and are not verified probabilities.

This is a partial sample. The provider event has 15 markets, and 12 are included [1]. The sample includes the 12 markets with the highest finite Yes prices, so the three omitted markets are not shown and should not be assumed to have lower prices than the included ones [1]. Do not treat these 12 rows as the full field, and do not combine these rankings with any other event or platform.

Volume is also not reported as a measure of liquidity or trader count here, so the snapshot does not show how many people hold each view.

What remains uncertain

The snapshot does not explain why prices are where they are. It also does not show whether prices have changed since the observation time. The excerpt does not include an "Other" price, so the sample cannot show how that outcome is priced. The rules also allow a consensus of credible reporting as a secondary source, which could matter if official statistics are unclear [1]. Because these are separate contracts with their own prices, a difference between them is not by itself an arbitrage opportunity.
