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 the ZCash Up or Down window labeled "October 20, 1:00AM-1:15AM ET" [1]. It resolves to "Up" if the time-weighted average price (TWAP) of ZCash, generated by Chainlink, over that window is greater than or equal to the price at the beginning of the range. Otherwise it resolves to "Down" [1]. The rules specify the ZEC/USD TWAP data stream and state that the market concerns that Chainlink feed, "not according to any other sources or spot markets" [1].
The listed end time is 2026-10-20T05:15:00.000Z [1]. That is a contract closing time, not a resolution. The source does not state when or how the market will be settled, so this snapshot cannot tell you the final result.
Reading the snapshot
The snapshot was observed at 2026-10-19T06:00:06.076Z and retrieved at 2026-10-19T06:12:18.845Z [1]. Both times describe a past moment. The provider status was "active" at the time of retrieval [1].
The saved market shows two outcomes, "Up" at 0.5 and "Down" at 0.5 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. A reader should not treat them as a forecast of where ZCash will trade. The record contains no volume or order-book depth, so it says nothing about liquidity or how many participants are involved.
The sample is complete for this event. Coverage lists one saved market, with one included and no partial sample [1]. Because there is only one market, there are no other outcomes or platforms in this record to compare against. Pricing for a different ZCash contract, such as a different time window or a different data source, would be a separate contract with different rules, so price gaps between such contracts should not be read as arbitrage.
What remains uncertain
The evidence does not explain why either outcome is priced at 0.5, and it does not show any price movement over time. It does not include the price at the start of the window, the TWAP result, or any settlement outcome. Because this is a 15-minute window, a reader should check the contract rules and the referenced Chainlink stream directly when the window closes rather than relying on this earlier snapshot.

Saved Oct 19, 2026 UTCOverview
This is a short-term crypto price contract on Polymarket about ZCash (ZEC) priced in US dollars. The title specifies a 15-minute window, October 20, 1:00AM to 1:15AM ET. The contract resolves to "Up" if the time-weighted average price (TWAP) of ZCash over that window is greater than or equal to the price at the beginning of the window. Otherwise it resolves to "Down" [1]. The measurement is specific. The resolution source is the ZEC/USD TWAP data stream published by Chainlink, not a general price feed or exchange quote. The source states that the market concerns the price according to that Chainlink data stream for the ZEC/USD pair, not according to any other sources or spot markets [1]. A trader therefore needs to understand the rule's measurement method, not only the general direction of ZCash's price. The listed end time is 2026-10-20T05:15:00.000Z [1]. The contract's rules set when the window closes. The title's ET times and the listed UTC end time describe the same window, but the listing does not indicate when the market itself will be resolved or settled. At the observation time recorded in the supplied data, 2026-10-19T06:00:06.076Z, the event showed two outcomes, "Up" and "Down," each at a price of 0.5 [1]. These are provider snapshot prices from that moment. They are not executable quotes, and they do not verify the probability of either outcome.
Why It Matters
The contract measures whether ZCash's Chainlink-reported ZEC/USD time-weighted average price over a 15-minute window ends at or above the price at the start of that window [1]. Because the comparison uses a TWAP rather than a single moment's price, the outcome depends on the average across the window relative to its starting level. The market's outcome is tied to that specific data stream, so readers should not assume that other exchanges or spot prices will produce the same result [1].
Snapshot context
