What the contract measures

This event asks about the margin of victory in the 2026 NY-09 House election, not simply who wins. The rules define the margin as "the absolute difference between the percentages of valid votes received by the first-place and second-place candidates" [1]. Each bracket is a separate Yes or No contract on a range of that margin, such as "by 55%-60%" or "by 65% or more." A separate contract asks whether the Republican Party candidate wins [1].

The rules include several details that affect how a bracket resolves. If the reported value "falls exactly between two brackets, then this market will resolve to the higher margin bracket" [1]. Ties follow a specific tiebreak, and the market resolves "based on the official vote count once the count has been made official" [1]. If a recount starts before the total is official, the market stays open until it is complete [1]. If results are not known definitively by June 30, 2027, 11:59 PM ET, the market resolves to "Other" [1].

The rules also say the election "is currently expected to be held on November 3, 2026" [1]. The listed end time is 2026-11-04T04:59:00.000Z [1]. This is the listed close time for the contracts, not a confirmed resolution date, and the rules allow for recounts and certification delays.

Reading the snapshot

The saved provider observation is timestamped 2026-10-15T21:00:05.939Z, and the source was retrieved at 2026-10-15T23:12:40.715Z [1]. Prices describe that observation only. They are not live quotes and should not be treated as current or executable.

In the saved sample, the Democratic bracket with the highest Yes price is "by 55%-60%" at 0.42, followed by "by 60%-65%" at 0.22 and "by 50%-55%" at 0.135 [1]. The Republican winner contract shows a Yes price of 0.0025 [1]. These contracts measure different things, so their prices should not be combined, compared as a single distribution, or averaged across brackets.

The sample includes 10 of 10 saved markets for this event, and the coverage record marks it as not partial [1]. The sample warning adds that this "does not establish that the providers list every possible real-world outcome" [1]. Because of that, a low price on one bracket does not show what would happen in an outcome that is not listed.

Volume and the number of traders are not part of this snapshot, so the prices do not show how many people hold a view or how deep the market is.

What remains uncertain

The supplied evidence contains one provider event from one platform. It does not explain why prices are where they are, and it does not show how these prices have performed in past elections. It also does not include any results, certification status, or news about the race. Prices of contracts with different wording, close times, or resolution rules should not be treated as an arbitrage signal without a careful reading of each contract's terms.
