About This Event
This market will resolve to "Up" if the time-weighted average price (TWAP) of Ethereum, 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 ETH/USD TWAP data stream available at https://data.chain.link/streams/eth-usd-twap-60s-streams. Please note that this market is about the price according to the TWAP Chainlink data stream for the asset pair ETH/USD, not according to any other sources or spot markets.

What the contract measures
This is a single Polymarket contract on whether Ethereum goes up or down over a five-minute window, from 7:05PM to 7:10PM ET on October 28 [1]. It resolves to "Up" if the time-weighted average price (TWAP) of Ethereum, generated by Chainlink, over that window is "greater than or equal to the price at the beginning of that range" [1]. Otherwise it resolves to "Down" [1]. The resolution source is the ETH/USD TWAP data stream from Chainlink, and the rules state that other sources or spot markets do not determine the outcome [1]. The listed end time is 2026-10-28T23:10:00.000Z [1].
Reading the snapshot
The saved snapshot was observed at 2026-10-28T00:00:06.241Z, and the source was retrieved at 2026-10-28T01:55:12.675Z [1]. The contract's listed end time is roughly 23:10 UTC, so the snapshot was taken well before the window closed. It is not a live reading.
The snapshot shows Up at 0.505 and Down at 0.495 [1]. These are prices from one saved observation, not executable quotes or verified probabilities. A small gap between the two sides is what the snapshot records, and it does not indicate how the market will settle. The sample includes one market from one provider event, and the coverage record marks it as complete for that event [1]. There is no other contract in this sample to compare against.
Volume is not included in this evidence, so nothing can be said about liquidity or the number of traders.
What remains uncertain
The evidence does not show the Ethereum price at the start or end of the window, so it does not indicate whether the contract has resolved or which side it will resolve to. The contract status was active when the source was captured [1].
The evidence also does not explain why the prices took the values they did. The rules are specific: the Chainlink TWAP stream governs, not other exchanges or spot markets [1]. A reader comparing this contract with a differently worded market on another platform should check the resolution source and time window, since a contract with different rules or close times is not directly comparable.

Saved Oct 28, 2026 UTCOverview
This PredictPedia entry covers a short-term Polymarket contract titled "Ethereum Up or Down - October 28, 7:05PM-7:10PM ET". The contract asks whether the price of Ethereum, measured over a five-minute window, will end up or down. According to the provider's event page, the market resolves to "Up" if the time-weighted average price (TWAP) of Ethereum, 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 resolution source is the ETH/USD TWAP data stream published by Chainlink. The provider states that the market concerns only this Chainlink data stream for the ETH/USD pair, and not any other price source or spot market [1]. This distinction matters because a trader reading general crypto news or a different exchange's quote could reach a different view of the price than the one the contract uses. The event page lists two outcomes, "Up" and "Down" [1]. The sample for this entry contains one market, and it is the only market saved for this provider event. The listed end time is 2026-10-28T23:10:00.000Z [1]. That timestamp is the contract's closing time as recorded by the provider. It is not an announcement of a separate event, and the page does not describe any other development affecting the contract. The question the contract poses is narrow. It does not ask where Ethereum will be on a given day or whether a longer trend will continue. It compares the average price across the named window with the price at the window's start, which means the result depends on the path of the price within the window as well as its endpoints [1].
Why It Matters
The contract measures a short, defined price comparison rather than a general view of Ethereum. Under the stated rules, the market resolves to "Up" if the time-weighted average price over the title's window is greater than or equal to the price at the start of that window, and to "Down" otherwise [1]. Because the reference is a time-weighted average from a named Chainlink data stream, the result can differ from what a single trade or a different venue's quote would suggest [1]. Understanding the exact resolution source is therefore the main way to interpret the contract's outcome.
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-28 at 00:00 UTC. It contains listings from Polymarket. Market descriptions and listed closing times define the contracts; they do not establish that the real-world outcome has occurred. This article does not include a separately verified news update. [1]
Frequently Asked Questions
What does the "Up" outcome mean in this contract?
According to the provider's rules, the market resolves to "Up" if the time-weighted average price of Ethereum over the window named in the title is greater than or equal to the price at the beginning of that window [1].
Which price source determines the result?
The resolution source is the ETH/USD TWAP data stream generated by Chainlink. The provider states that other sources and spot markets are not used to decide the market [1].
Is the date in the title the same as the contract's closing time?
The title names the time range, and the listed end time recorded by the provider is 2026-10-28T23:10:00.000Z [1]. The provider's record gives this closing time, and it is not described as a separate announced event.
Does a price on this market show what will happen to Ethereum?
The page presents prices for the two outcomes but does not state that they are verified probabilities [1]. A market price reflects the contract's trading at the time it was observed, and the contract concerns only the defined Chainlink window.
