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
The market is titled "ZCash Up or Down - October 20, 4:15AM-4:20AM ET" and is categorized as Crypto [1]. Its rules state that 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 specify that the market concerns "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].
The contract is therefore about a five-minute average compared with a starting price, not about a single trade or a spot quote on another venue. The listed end time is 2026-10-20T08:20:00.000Z [1]. The title's Eastern Time window and the listed UTC end time describe the same close, but a reader should use the stated rules and the listed end time rather than assuming a different platform would define the window the same way.
Reading the snapshot
The saved snapshot was observed at 2026-10-19T09:00:05.974Z and retrieved at 2026-10-19T10:00:29.910Z [1]. It reports provider status "active" [1]. At observation, the saved prices were 0.5 for "Up" and 0.5 for "Down" [1].
This sample contains one market from one provider event. The coverage record shows 1 total market and 1 included market, with no partial sample [1]. Because the sample is complete for this saved event, no outcome has been omitted from it. The sample warning, however, states that this "does not establish that the providers list every possible real-world outcome" [1]. For a binary Up or Down contract, the two saved prices are the only outcomes shown.
The equal prices describe only the moment of observation. They are not an executable quote, a verified probability, or a measure of liquidity. The source material does not include volume, order book depth, or trader counts, so nothing about those can be stated.
What remains uncertain
This snapshot is from 19 October 2026 and cannot describe prices after its observation time. The evidence does not show whether the price has changed since then, whether the market is still open at the time a reader views it, or how the TWAP will compare with the starting price when the window closes.
The evidence also does not explain why the saved prices are equal. No news, trading activity, or other cause is supplied, so none should be inferred.
Finally, this market should be compared only with contracts that use the same rules, data source, and close time. A similar Up or Down contract on another platform, or one with a different window or data feed, is not directly comparable, and any price difference between them would not by itself indicate an opportunity.

Saved Oct 19, 2026 UTCOverview
This PredictPedia entry covers a short-term binary contract on the price of ZCash (ZEC) against US dollars, listed on Polymarket under the title "ZCash Up or Down - October 20, 4:15AM-4:20AM ET" [1]. The contract asks whether the price of ZEC will move up or down over a five-minute window. It is classified as a crypto market [1]. The resolution rule is set by the contract itself. The market resolves to "Up" if the time-weighted average price (TWAP) of ZCash over the time range in the title is greater than or equal to the price at the beginning of that range. Otherwise it resolves to "Down" [1]. Because the comparison uses the equal-or-greater test, a flat reading resolves to "Up" under the stated rule. The resolution source is named in the contract as Chainlink, specifically its ZEC/USD TWAP data stream with a 60-second interval [1]. The rules state that only this Chainlink data stream counts, not other sources or spot markets for the same asset pair [1]. A reader should therefore check the Chainlink stream, rather than a general exchange price, when reviewing how the contract will be settled. The listed end time is 2026-10-20T08:20:00Z [1]. That timestamp is when the contract's stated window closes. It is not the moment the outcome is announced or paid out, and the rules in the source do not describe a separate settlement announcement. The platform's saved record shows the market as active, with two outcomes, "Up" and "Down" [1]. The application's dated snapshot shows the prices at the time the provider was observed, and those figures are not executable quotes. Any price reflects that single observation rather than the market's state today.
Why It Matters
The contract measures whether the time-weighted average price of ZEC/USD, as reported by the Chainlink TWAP data stream, over a five-minute window ending at the stated time is at or above the price at the start of that window [1]. Because the window is short and the rule is based on an average rather than a single trade, the outcome depends on the reported data stream, not on the last price a user saw on a trading venue [1]. The contract's rules explicitly exclude other sources and spot markets [1], so the wording of the rules is central to understanding what the contract tracks.
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-19 at 09:00 UTC. It contains listings from Polymarket. Market descriptions and listed closing times define the contracts; they do not establish that the real-world outcome has occurred. This article does not include a separately verified news update. [1]
Frequently Asked Questions
What determines whether this contract resolves Up or Down?
It compares the time-weighted average price of ZCash over the time range in the title with the price at the beginning of that range. If the average is greater than or equal to the starting price, it resolves to Up. Otherwise it resolves to Down [1].
Which data source is used to settle the contract?
The resolution source is Chainlink's ZEC/USD TWAP data stream with a 60-second interval. The rules say that other sources or spot markets for the pair are not used [1].
When does the contract's window end?
The listed end time is 2026-10-20T08:20:00Z [1]. The title describes the window as 4:15AM to 4:20AM ET on October 20 [1].
Does a contract price show the chance that ZEC will rise?
The contract's rules define the resolution conditions but do not describe what its price means as a forecast. A price is only a snapshot of trading at one moment and is not a verified probability [1].
