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 Polymarket contract on whether the ZEC/USD price will be up or down over a specific window. The title gives the window as "October 20, 4:45AM-5:00AM ET" [1]. The rules say the market resolves 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 resolves to "Down" [1]. The resolution source is the ZEC/USD TWAP data stream, 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].
The listed end time is 2026-10-20T09:00:00.000Z [1]. The title uses Eastern Time while the listed end time is in UTC, so readers comparing the two should convert them deliberately. The evidence does not state the conversion for you.
Reading the snapshot
The saved provider observation was taken at 2026-10-19T09:00:05.974Z, and the source was retrieved at 2026-10-19T09:39:17.855Z [1]. These are different moments, and neither is the contract's closing time or its resolution. The record shows the Up outcome at 0.5 and the Down outcome at 0.5 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities.
The sample covers one saved market for this event, with no partial sampling [1]. Because only these two outcomes are listed, there is no omitted outcome in this record. Volume is not included in the evidence used here, so nothing can be said about liquidity or the number of traders.
The contract is not directly comparable to other ZEC or crypto contracts with different windows, wording, or close times. A difference in price between two such contracts would not by itself indicate an opportunity.
What remains uncertain
The evidence does not explain why the prices are at 0.5, and it contains no recent news or commentary on ZEC. It also does not show how the price has moved since the snapshot. The outcome will depend on the Chainlink TWAP calculated over the stated window, which has not been observed in the supplied material. Readers should check the provider page for any later status, since the excerpt reflects only the retrieved record.

Saved Oct 19, 2026 UTCOverview
This PredictPedia entry covers a short-window market on Polymarket titled "ZCash Up or Down - October 20, 4:45AM-5:00AM ET." The contract asks whether the price of ZCash will end the stated window at or above where it started. The market is categorized under crypto [1]. Its listed end time is 2026-10-20T09:00:00.000Z [1]. The contract's rules tie resolution to a time-weighted average price (TWAP) rather than a single trade. Under these rules, the market resolves to "Up" if the TWAP over the time range in the title is greater than or equal to the price at the beginning of that range, and to "Down" otherwise [1]. The rules name Chainlink as the resolution source, specifically its ZEC/USD TWAP data stream [1]. The rules also state that the market concerns the price according to that Chainlink TWAP data stream, not any other sources or spot markets [1]. Traders reading the contract should therefore focus on that data stream's definition of the window rather than on prices quoted elsewhere. The market was observed at 2026-10-19T09:00:05.974Z and the source record was retrieved at 2026-10-19T09:39:17.868Z [1]. The observation time and retrieval time are both earlier than the listed end time, and the contract had not closed when these records were made. Neither the observation nor the retrieval establishes the market's status at any later time.
Why It Matters
The contract measures the direction of ZCash's price over a fifteen-minute window, as defined by a specific Chainlink TWAP data stream [1]. Because the outcome compares an average over the window with the price at the window's start, it captures the net movement of that averaged series rather than the closing price of any single exchange [1]. The rules' explicit reference to one data stream means that a different price feed or spot venue would not, under these rules, determine the result [1]. This makes the data stream definition the central technical detail for anyone reading the market. The only market in the saved sample is the Up or Down contract itself, with two outcomes labeled Up and Down [1]. The saved snapshot shows both outcomes priced at 0.5 [1]. That is a price snapshot taken at the observation time. It is not an executable quote, and it is not a verified probability that ZCash will rise or fall.
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 market resolves Up or Down?
The market resolves to "Up" if the 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].
Which price data does the contract use?
The resolution source is the Chainlink ZEC/USD TWAP data stream, and the rules say the market is not based on other sources or spot markets [1].
Does the 0.5 price mean there is a 50 percent chance of an Up result?
No. The record shows Up and Down priced at 0.5 at the observation time [1]. That is a snapshot and not a verified probability or an executable quote.
When was this market last observed?
It was observed at 2026-10-19T09:00:05.974Z and retrieved at 2026-10-19T09:39:17.868Z, before the listed end time of 2026-10-20T09:00:00.000Z [1].
