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 titled "ZCash Up or Down - October 20, 12:15AM-12:20AM ET" [1]. The source states 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"." The resolution source is the ZEC/USD TWAP data stream named in the source, and the source stresses 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 listed end time is 2026-10-20T04:20:00.000Z, and the provider status at retrieval was "active" [1]. A listed end time is the provider's scheduled close, not a record that the market has resolved. The evidence does not show a resolution outcome.
Reading the snapshot
The provider observation time is 2026-10-19T06:00:06.076Z, and the source was retrieved at 2026-10-19T06:57:07.743Z [1]. These are two different timestamps, and both describe a past moment relative to any later reading. The prices below describe that observation only.
The saved snapshot shows "Up" at 0.5 and "Down" at 0.5 [1]. Because this is a binary contract with one event, the two prices sit at an even split in this snapshot. These are quoted snapshot prices, not executable quotes, and they are not verified probabilities.
The sample covers one market from one provider event. The coverage record shows one total market, one included market, and no partial sample [1]. Since there is only one platform and one contract, no cross-platform comparison is possible here, and no averaging across contracts is appropriate.
What remains uncertain
The evidence does not include volume, order book depth, or a count of traders, so it says nothing about liquidity. The source also does not explain any price movement. A reader comparing this contract with a differently worded market should note that the rules here depend on a TWAP over a specific window and a comparison with the price at the start of that window. A market with different wording or a different close time may not measure the same thing, so differing prices would not by themselves indicate an arbitrage opportunity.

Saved Oct 19, 2026 UTCOverview
This market is a short-window contract on the price of ZCash, measured in US dollars, that is listed on Polymarket under the title "ZCash Up or Down - October 20, 12:15AM-12:20AM ET" [1]. It belongs to the crypto category and asks whether the asset's price will be higher or lower over a five-minute range. The contract has two outcomes, "Up" and "Down" [1]. The rules say the market resolves to "Up" if the time-weighted average price 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 comparison is therefore between an average taken across the window and the starting price, not between the price at the start and the price at the end. The resolution source is Chainlink's ZEC/USD time-weighted average price data stream, which is a 60-second TWAP stream [1]. The rules state that only this Chainlink data stream counts. Other sources and spot markets do not determine the outcome [1]. Traders reading prices on exchanges should therefore keep in mind that the resolution is tied to this specific feed. The listed end time is 2026-10-20T04:20:00Z, which corresponds to the 12:20 AM ET end of the title's window [1]. This is the scheduled close recorded in the contract, not a record of when trading or resolution actually occurred. The listed end time is later than the time the source was retrieved, so the window had not yet closed at that point.
Why It Matters
The contract measures whether the average ZCash price over a five-minute window is at least as high as the price at the start of that window, using one named Chainlink data stream [1]. Because the comparison uses a time-weighted average rather than a single closing print, a move that happens near the end of the window may affect the average differently than the final price. Anyone reading the contract should check the exact wording of the rules, since the outcome depends on the specified feed and the equal-or-greater comparison [1].
