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 snapshot covers one Polymarket contract, "ZCash Up or Down - October 28, 9:45PM-9:50PM ET" [1]. According to the saved rules, the market resolves to "Up" if the time-weighted average price (TWAP) of ZCash, generated by Chainlink, 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 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]. The resolution source is the ZEC/USD TWAP data stream [1].
The listed end time is 2026-10-29T01:50:00.000Z [1]. That matches the 9:50PM ET end of the title's window, but this contract's close time is the listed end time, not the date in the title. The contract's resolution is a separate event that the evidence does not show as having occurred.
Reading the snapshot
The provider observation time is 2026-10-28T03:00:06Z, and the source was retrieved at 2026-10-28T06:01:46Z [1]. The prices below describe that observation only. They are not live prices, and the evidence does not show how they have changed since.
At observation, the outcomes were priced as follows: "Up" at 0.5 and "Down" at 0.5, with the provider status recorded as active [1]. Equal prices mean the snapshot did not favor either outcome. These are quoted prices, not executable quotes or verified probabilities, so they do not establish the likelihood of either result.
The sample is complete for this provider event. The coverage record shows one saved market, one included, and no partial sample [1]. Because both outcomes are listed, no outcome is omitted.
What remains uncertain
The evidence does not include trading volume, order book depth, or any information about how many participants hold each position. Volume is not a measure of liquidity or trader count, so the snapshot cannot indicate how easily a position could be entered or exited.
The evidence also does not explain why prices stood where they did. It contains no news, no event context, and no historical accuracy data for this kind of market.
Finally, the outcome depends on Chainlink TWAP data over the stated window. Comparing this contract with a different ZCash market or another platform would require checking whether the rules, windows, and resolution sources match. Differences in wording or close times can make prices non-comparable, so a price gap alone would not indicate an opportunity.

Saved Oct 28, 2026 UTCOverview
This PredictPedia entry covers a short-term crypto price contract on Polymarket titled "ZCash Up or Down - October 28, 9:45PM-9:50PM ET" [1]. The contract is a binary market in the crypto category with two outcomes, Up and Down [1]. It asks whether ZCash's price moves up or down over a five-minute window, measured against a specific data feed rather than general market prices. The resolution rule is the core of the contract. 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 reference is the ZEC/USD TWAP data stream published by Chainlink, not other exchanges or spot markets [1]. Because the contract compares an average over the window with the starting price, a move that looks upward at the final moment does not by itself determine the result. The listed end time is 2026-10-29T01:50:00Z [1]. Converted to Eastern Time, that is 9:50 PM on October 28, which matches the window named in the title. This end time is the contract's listed closing point, not a record of when a result was determined. The provider status recorded for the event is active [1].
Why It Matters
The contract measures the direction of ZCash's price over one specific five-minute window, using a time-weighted average from a named Chainlink data stream [1]. Because it is short and binary, it isolates a single directional question about the ZEC/USD reference rather than a broader view of the asset. Readers should note that the rule depends on the TWAP data stream specifically. Any difference between that stream and other price sources would not change the outcome under the stated rule [1].
