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 the ZCash price over the window named in its title, 8:30PM to 8:35PM ET on October 28 [1]. 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 contract states that it 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]. Any reader comparing this contract with a different ZCash market should check whether that market uses the same data source, averaging method, and window.

The listed end time is 2026-10-29T00:35:00.000Z, which matches the close of the 8:35PM ET window [1]. This is the listed close time in the contract data, not a confirmed resolution, and the excerpt does not report a resolved outcome.

Reading the snapshot

The saved snapshot was observed at 2026-10-28T03:00:06.402Z and retrieved at 2026-10-28T05:44:09.906Z [1]. It is therefore a record of prices from about 2 hours and 44 minutes before the retrieval time, and it should not be read as a live view. The provider status at retrieval was "active" [1].

The snapshot lists two outcomes, "Up" at 0.5 and "Down" at 0.5 [1]. These are observed prices, not executable quotes or verified probabilities. Equal prices in this snapshot show that the two sides were quoted at the same level at that observation time. They do not show why that level was reached, and the evidence does not include volume, depth, or the number of participants, so it cannot indicate liquidity.

The sample covers one market from one provider event. Coverage is complete for that event, with one market included out of one total and no partial sample [1]. The sample does not establish a full field of possible outcomes, but for a binary contract the two listed outcomes are the only ones in this record.

What remains uncertain

The evidence does not show the ZCash price at the start of the window, the TWAP over the window, or the final result. It also does not show any price movement after 03:00 UTC on October 28, 2026. Because the data is a single snapshot, it cannot support claims about trends, trader sentiment, or how the market has behaved over time. Any comparison with a contract on another platform would require matching the resolution source, window, and close time before the prices could be discussed together.

Overview

This PredictPedia entry covers a short-term price contract on ZCash (ZEC) against the US dollar, titled "ZCash Up or Down - October 28, 8:30PM-8:35PM ET" and listed in the Crypto category on Polymarket [1]. The contract asks whether ZEC's price will finish the five-minute window higher or lower than where it started. Under the rules, the market resolves to "Up" if the time-weighted average price (TWAP) of ZEC over the window is greater than or equal to the price at the beginning of that window. Otherwise it resolves to "Down" [1]. The resolution source is the Chainlink ZEC/USD TWAP data stream, not spot exchange prices or other feeds. The rules state that only this Chainlink price stream counts, so a move visible on a different exchange or price site would not by itself decide the contract [1]. Because the outcome depends on an average over the window rather than a single closing print, a price that rises early and then falls back can still resolve "Up" if the average stays at or above the starting level. The reverse is also possible. In the saved record, the two outcomes were listed at 0.5 each, and the provider status was active with a listed end time of 2026-10-29T00:35:00Z [1]. These figures are a snapshot from the time the record was observed. They are not an executable quote, and they are not a verified probability that ZEC will rise. The saved record contains only this one market, so there is no comparison with other contracts in this set.

Why It Matters

The contract measures the direction of ZEC/USD over one five-minute window, as reported by the Chainlink TWAP data stream [1]. Because it is tied to a specific data stream and a time-weighted average, it tests whether the average price over the period is at or above the price when the period began. It does not measure a broader view of ZCash's value, its trading volume, or its performance over longer periods. Readers should treat the contract rules as the authoritative definition of what settles it, since the saved record does not describe any other settlement method [1].

Snapshot context

The latest published provider snapshot for this topic was observed on 2026-10-28 at 03:00 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.

Frequently Asked Questions

What decides whether this contract resolves Up or Down?

The contract compares the time-weighted average price of ZEC over the stated window with the price at the start of that window. If the average is greater than or equal to the starting price, it resolves Up. Otherwise it resolves Down [1].

Which price source is used for settlement?

The resolution source is the Chainlink ZEC/USD TWAP data stream. The rules say the market concerns that stream and not other sources or spot markets [1].

Does the listed end time match the ET window in the title?

The title gives the window as 8:30PM to 8:35PM ET on October 28. The listed end time in the record is 2026-10-29T00:35:00Z, which is written in UTC [1]. The record does not state a separate settlement announcement or result.

Do the listed prices show the chance that ZEC will rise?

No. The saved record shows 0.5 for both Up and Down at the time it was observed. Prices in this record are snapshots and not executable quotes or verified probabilities [1].
