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 titled "Ethereum Up or Down - October 26, 9:35AM-9:40AM ET" [1]. The rules say it "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, and the rules state that the market concerns "the price according to the TWAP Chainlink data stream for the asset pair ETH/USD, not according to any other sources or spot markets" [1].
Because the outcome depends on a time-weighted average rather than a single trade price, a comparison with a spot-price market or a different oracle could resolve differently even over the same window. The listed end time is 2026-10-26T13:40:00.000Z [1]. That is the contract's listed close, not a confirmed resolution time.
Reading the snapshot
The saved observation was taken at 2026-10-25T15:00:05.906Z, and the source was retrieved at 2026-10-25T15:37:46.374Z [1]. The prices below describe that earlier observation, not live conditions:
- Up: 0.505
- Down: 0.495
The sample contains one market from one provider event, and the coverage record shows no partial sample [1]. Because the two outcomes are the complete binary set for this contract, the prices sum to 1.000 in this snapshot. The Up price is only slightly above the Down price.
These are quoted snapshot prices, not executable quotes or verified probabilities. The evidence does not include order-book depth, spreads, or trade volume, so it does not show how easily a position could be entered or exited. Nothing here explains why the prices stood where they did.
What remains uncertain
The evidence does not show prices after the observation time, so it cannot say where the contract trades now. It also does not establish the final TWAP or the resolved outcome. The contract is also a narrow five-minute window, so the rules alone do not indicate how the TWAP will compare with the starting price. Comparing this contract with markets that use different wording, oracles, or close times would not be a like-for-like comparison.

Saved Oct 25, 2026 UTCOverview
This market is a short-window price contract on Ethereum, titled "Ethereum Up or Down - October 26, 9:35AM-9:40AM ET" and listed on Polymarket [1]. Its rules state that it 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 contract therefore asks whether the average price across the five-minute window ends up at or above the starting price, rather than whether the price is higher at a single instant. The resolution source is named in the rules as Chainlink's ETH/USD TWAP data stream, a 60-second TWAP stream [1]. The rules say the market concerns the price according to that Chainlink data stream for the ETH/USD pair, and not according to any other sources or spot markets [1]. A reader comparing this contract with a prices shown on an exchange or another data feed should keep that distinction in mind, because a different source could show a different outcome. The listed end time in the source is 2026-10-26T13:40:00.000Z [1]. The window in the title is given in Eastern Time, so the end of the observation range is the moment the title's 9:40AM ET boundary falls. The listed end time marks when the contract closes in the provider's data, while the outcome is determined by the Chainlink TWAP data for the window.
Why It Matters
The contract measures the direction of the Ethereum price over a five-minute window, as reflected in the Chainlink ETH/USD TWAP data stream [1]. Because the outcome compares the window's average price to the price at the start of the window, it reflects movement across the interval rather than a single closing value [1]. The contract's wording limits the measurement to that one data stream, so its result depends on the rules and data source named in the listing [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-25 at 15:00 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 an "Up" outcome mean for this contract?
According to the rules, the market resolves to "Up" if the Chainlink TWAP of Ethereum over the time range in the title is greater than or equal to the price at the beginning of that range [1].
What happens if the average price is below the starting price?
In that case the market resolves to "Down" under the stated rules [1].
Which price data determines the outcome?
The resolution source is Chainlink's ETH/USD TWAP data stream, and the rules specify that other sources or spot markets are not used [1].
Why is the time window written in Eastern Time while the end time is in UTC?
The title gives the window as 9:35AM to 9:40AM ET, and the provider lists the end time as 2026-10-26T13:40:00.000Z [1]. The listing presents both times, so the title and the listed end time describe the same window boundary.
