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, "ZCash Up or Down - October 28, 10:30AM-10:45AM ET" [1]. Its rules state that the 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"" [1]. The resolution source is the Chainlink ZEC/USD TWAP data stream, and the rules say the market is "not according to any other sources or spot markets" [1]. A reader should therefore compare the outcome to the Chainlink TWAP over the window, not to a general ZEC price quote.

The listed end time is 2026-10-28T14:45:00Z, while the title gives the window in Eastern Time [1]. The end time is the listed close, not a confirmed resolution, and the supplied evidence does not record how the market settled.

Reading the snapshot

The provider observation time is 2026-10-27T21:00:06Z, and the source was retrieved at 2026-10-27T23:29:34Z [1]. These are snapshot times. The prices below describe that observation only and do not show the current market.

The saved market lists "Up" at 0.5 and "Down" at 0.5 [1]. Because both outcomes are priced equally in this snapshot, it shows no lean toward either side at that moment. These are quoted snapshot prices, not executable quotes or verified probabilities. The evidence does not include volume, trade counts, or depth, so it says nothing about liquidity or how many participants hold either view.

The sample covers one saved market, and coverage is complete for that event [1]. No other platform or contract is included, so no cross-platform comparison is possible here.

What remains uncertain

The evidence does not explain why the prices stand where they do. It does not show any news, price history, or later quotes. It also does not confirm whether the market is still active, since the provider status was active only at retrieval time [1]. The sample warning notes that saved markets do not establish a complete list of possible outcomes, but this is a binary contract, so that limit mainly affects the event framing rather than this comparison [1]. A reader who needs current prices or settlement should check the provider directly after the listed end time.

Overview

This PredictPedia entry covers a short-duration Polymarket contract titled "ZCash Up or Down - October 28, 10:30AM-10:45AM ET" [1]. The contract is in the crypto category and asks whether the price of ZCash will be higher or lower over a 15-minute window. According to the contract rules, 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]. The price reference is not a general market price. The contract specifies that the resolution source is information from Chainlink, specifically the ZEC/USD TWAP data stream [1]. The rules also state that the market concerns the price according to that Chainlink TWAP data stream for the ZEC/USD pair, and not according to other sources or spot markets [1]. A reader comparing this contract with a price shown on an exchange or aggregator should keep that distinction in mind, because the outcome depends only on the named data stream. The saved record lists the contract as active, with a listed end time of 2026-10-28T14:45:00.000Z [1]. That end time is the contract's closing time as recorded in the listing. It is not an announced event, and the 10:30 to 10:45 AM ET window describes the period the contract measures rather than a scheduled release or news event. The contract has two outcomes, "Up" and "Down" [1]. Whether either outcome has resolved is not established by the saved record, since it reflects the listing at its observation time.

Why It Matters

The contract measures the direction of ZCash's price over a fixed 15-minute window, as defined by a specific Chainlink TWAP data stream [1]. Because the resolution uses a time-weighted average rather than a single trade price, the outcome reflects the average over the window compared with the price at the start of the window [1]. This makes the rule details, including the named data stream and the start-of-range comparison, the core of how the contract is decided [1]. Users who rely on the contract should read the resolution wording directly, since it limits the outcome to that specific feed [1].
