About This Event
This market will resolve to "Up" if the time-weighted average price (TWAP) of ZCash, generated by Chainlink, of the time range specified in the title is greater than or equal to the price at the beginning of that range. Otherwise, it will resolve to "Down". The resolution source for this market is information from Chainlink, specifically the ZEC/USD TWAP data stream available at https://data.chain.link/streams/zec-usd-twap-60s-streams. Please note that this market is about the price according to the TWAP Chainlink data stream for the asset pair ZEC/USD, not according to any other sources or spot markets.

What the contract measures
This is a single binary contract on Polymarket for ZCash over a 15-minute window, titled "ZCash Up or Down - October 19, 10:15PM-10:30PM ET" [1]. The rules say it "will resolve to "Up" if the time-weighted average price (TWAP) of ZCash, generated by Chainlink, of the time range specified in the title is greater than or equal to the price at the beginning of that range. Otherwise, it will resolve to "Down"" [1].
The resolution source is the ZEC/USD TWAP data stream from Chainlink, and the rules state that the market "is about the price according to the TWAP Chainlink data stream for the asset pair ZEC/USD, not according to any other sources or spot markets" [1]. A reader should not assume that a spot price on another exchange or a different ZEC pair determines the outcome.
Timing needs care. The title uses Eastern Time, while the listed end time is given in UTC as 2026-10-20T02:30:00.000Z [1]. The end time is the listed close, not a confirmed resolution time, and this snapshot does not show how or when the contract was settled.
Reading the snapshot
The saved provider observation was taken at 2026-10-19T03:00:06Z, and the record was retrieved at 2026-10-19T04:10:51Z [1]. Both times predate the current date in this evidence and describe a past state. They do not show live prices now.
At observation, the contract showed "Up" at 0.5 and "Down" at 0.5 [1]. These are snapshot prices, not executable quotes or verified probabilities. An equal split means only that these two quoted prices matched at that moment. It does not indicate agreement among traders, since the evidence contains no trader counts, and volume is not reported here.
The sample covers one market from one event, and the coverage record shows no partial sample [1]. Because only one contract is included, there is no other outcome to compare or average against.
What remains uncertain
The evidence does not show any price movement after the observation time, the contract's settlement outcome, or the reasons for the quoted prices. Comparing this contract with similar ZCash windows on other platforms would require different rules, close times, and possibly different resolution sources, so their prices should not be treated as directly comparable or as an arbitrage signal.

Saved Oct 19, 2026 UTCOverview
This PredictPedia entry covers a short-term binary contract on the price direction of ZCash (ZEC) against the US dollar. The market is titled "ZCash Up or Down - October 19, 10:15PM-10:30PM ET" and is listed in the Crypto category [1]. The contract is based on a time window, not a single moment. According to the provider's rules, it resolves to "Up" if the time-weighted average price (TWAP) of ZCash over the window in the title is greater than or equal to the price at the beginning of that window. Otherwise it resolves to "Down" [1]. The resolution source is Chainlink. The rules name its ZEC/USD TWAP data stream, with a 60-second TWAP configuration, as the reference for settlement [1]. The provider states that the market concerns the price in that Chainlink data stream only, not any other data source or spot market [1]. Traders therefore need to read the rules closely, because a price on another exchange or index could differ from the value that determines the outcome. The saved record lists two outcomes, Up and Down, each with a price of 0.5 at the observation time of 2026-10-19T03:00:06Z [1]. These values are snapshots taken from the provider's data. They are not executable quotes, and they should not be read as verified probabilities. The record also lists the contract's end time as 2026-10-20T02:30:00Z, and the provider status as active [1]. The end time is when the window closes under the contract rules. It is not a statement about when any result will be announced or settled in practice. Volume and the number of participants are separate from price. The saved sample contains only this one market for this event, so no other outcomes can be compared against it.
Why It Matters
The contract measures whether the time-weighted average price of ZEC/USD, as reported in a specified Chainlink data stream, over a set 15-minute window is at or above the price at the start of that window [1]. Because it uses an average over the window rather than a single closing price, the outcome depends on the path of the price during the period as well as its final level [1]. Users should note that the rules define the reference data precisely, so the contract tracks that stream rather than the wider crypto market [1].
