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 Polymarket contract covers ZCash in the 10:00PM to 10:15PM ET window on October 19, 2026. According to the rules, 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 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]. A contract on a different ZCash price source, or a different window, would not be comparable to this one.
Reading the snapshot
The provider observed this market at 2026-10-19T03:00:06Z, and the record was retrieved at 2026-10-19T04:10:51Z [1]. The listed end time is 2026-10-20T02:15:00Z, and the provider status is "active" [1]. The observation is a snapshot from an earlier time, not a live reading. The contract had not reached its listed end time when the record was retrieved.
The saved prices are 0.5 for "Up" and 0.5 for "Down" [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The record does not include volume, order book depth, or trader counts, so it says nothing about liquidity or how many participants hold either side.
The sample contains one Polymarket market for this event. Coverage is complete, with one market included out of one total, and the record is not marked as a partial sample [1]. Because only this contract is saved, there are no other outcomes or platforms to compare against.
What remains uncertain
The record does not explain why the prices sit at 0.5, and it does not report any news or events affecting ZCash in this window. The outcome is undetermined in the evidence, because the contract had not closed and no resolution is recorded. The title states the window in Eastern time, while the rules use UTC timestamps, so readers should check both when comparing the listed end time with the stated window. Finally, the saved record captures one moment, so later prices may differ.

Saved Oct 19, 2026 UTCOverview
This market is a short-term price contract on ZCash (ZEC) against the US dollar, titled "ZCash Up or Down - October 19, 10:00PM-10:15PM ET" and listed on Polymarket [1]. The contract asks whether the asset's price will rise or fall over one fixed 15-minute window. According to the contract rules, it 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]. The resolution source is Chainlink. The rules specify the ZEC/USD TWAP data stream, and state that the market concerns the price in that Chainlink stream and not any other data source or spot market [1]. This matters because a trader reading a different exchange's price for ZCash at the same moment may see a different number than the one that settles the contract. The listed end time is 2026-10-20T02:15:00.000Z, which corresponds to 10:15 PM Eastern Time on October 19, 2026 [1]. That date is the scheduled end of the measurement window stated in the contract, not a separately announced event. The provider lists the market as active [1].
Why It Matters
The contract measures the direction of ZCash's Chainlink-reported ZEC/USD price over a single 15-minute window, using a time-weighted average rather than a single trade price [1]. Because the comparison is between the average over the window and the price at the window's start, the outcome depends on how the price behaves across the whole interval and not only on where it ends [1]. The contract's rules name one specific data stream as the basis for settlement, so the resolution is tied to that feed's values [1]. The price shown for the contract on the provider page is a snapshot that was recorded at 2026-10-19T03:00:06Z. Both outcomes were priced at 0.5 in that snapshot [1]. A snapshot like this reflects the observed market price at that time and is not an executable quote or a verified probability of either outcome.
