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 snapshot covers one Polymarket event, "Ethereum Up or Down - October 20, 3:35AM-3:40AM ET," in the Crypto category [1]. The rules state that the 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"" [1]. The resolution source is the ETH/USD TWAP data stream from Chainlink, and the rules say the market is "not according to any other sources or spot markets" [1].
The listed end time is 2026-10-20T07:40:00.000Z [1]. The title's window is written in Eastern Time, so readers should compare the listed UTC end time with their own time zone before relying on the window.
Reading the snapshot
The saved provider observation time is 2026-10-19T09:00:05.974Z, and the source was retrieved at 2026-10-19T09:19:11.840Z [1]. These are different timestamps. The observation describes the provider's data at that moment, and the retrieval time describes when this record was collected. The provider status at collection was "active" [1].
The saved prices were Up at 0.505 and Down at 0.495 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The two outcomes sum to 1.000 in this record. The evidence does not include volume, order book depth, or trader counts, so it says nothing about liquidity or how many participants hold either side.
The coverage record lists one market for this event, with one included and no partial sample [1]. Because this is a single binary contract on a single platform, there is no comparison across contracts here. The source does not show a second platform or related contract, so no cross-platform comparison is possible from this evidence.
What remains uncertain
The evidence does not show the price at any time after the observation, nor whether the market has resolved. It also does not explain why the prices are where they are. Because the record shows only one market, it cannot indicate how this contract compares with similar windows or other platforms. Readers should check the live contract and its rules directly before drawing conclusions about the outcome or the market.

Saved Oct 19, 2026 UTCOverview
This is a short-window price contract on Ethereum. The market asks whether the ETH/USD price will finish a specified window at or above where it began. The provider's rules say 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 start of that range. Otherwise it resolves to "Down" [1]. The resolution source is Chainlink's ETH/USD TWAP data stream, with a 60-second TWAP referenced in the source link [1]. The rules state that only this Chainlink data stream counts, not other price sources or spot markets [1]. A trader reading this contract should therefore focus on the Chainlink series, not on the price shown on any exchange. The event title gives the window as 3:35AM to 3:40AM ET on October 20. The provider lists the end time as 07:40 UTC on October 20, 2026 [1]. The provider's status at the time of the saved record was active [1]. That status describes the record as it was saved, not the state of the market at the time you are reading this.
Why It Matters
The contract measures whether Ethereum's TWAP over a five-minute window ends at or above its starting level, as reported by the Chainlink ETH/USD TWAP data stream [1]. Because the rule compares an average over the window with the price at the start, the outcome depends on the data stream's readings rather than on the closing print of a single trade. The contract's rules explicitly exclude other sources and spot markets [1], so a movement on another venue does not by itself decide the result.
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-19 at 09:00 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 for this contract?
Up resolves if the TWAP of ETH/USD over the stated window is greater than or equal to the price at the beginning of that window, according to Chainlink's data stream [1].
Which price source decides the result?
The rules name Chainlink's ETH/USD TWAP data stream as the resolution source and state that other sources or spot markets are not used [1].
When does the window close?
The provider lists the end time as 07:40 UTC on October 20, 2026, which corresponds to the 3:40AM ET end in the event title [1].
