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 Polymarket event is titled "Ethereum Up or Down - October 27, 7:25AM-7:30AM ET" [1]. The rule states 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 resolves to "Down" [1]. The resolution source is the Chainlink ETH/USD TWAP data stream. The rule also says the 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" [1].
The listed end time is 2026-10-27T11:30:00.000Z [1]. The title uses Eastern Time, while the listed end time is in UTC. Readers comparing this contract with other ether markets should check both fields rather than assume they match.
Reading the snapshot
The saved snapshot was observed at 2026-10-26T15:00:05.977Z and retrieved at 2026-10-26T17:45:40.955Z. The provider status was recorded as active at retrieval [1]. The quoted prices were 0.505 for Up and 0.495 for Down [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The two outcomes sum to 1.00 in this sample, so the snapshot shows a close split between the two stated outcomes at observation time. It does not show the price now.
The sample contains one market from one platform, and it is not partial within that provider event. No cross-platform comparison is possible. The supplied evidence includes no volume or liquidity figures, so it says nothing about market depth or how many participants are trading.
What remains uncertain
The evidence does not show the current price, the outcome, or whether the contract has closed or resolved. The "active" status applies only to the retrieval time. Nothing in the supplied material explains why the quoted prices took their observed values. Before relying on any figure, readers should check the provider page for the current status and price.

Saved Oct 26, 2026 UTCOverview
This is a short-window crypto price contract on Polymarket titled "Ethereum Up or Down - October 27, 7:25AM-7:30AM ET" [1]. It asks whether the price of Ether will finish a five-minute window higher or lower than where it started. The contract is classified under the Crypto category and is listed as a single market within its event [1]. The rules define the outcome by a specific data feed rather than by any general market price. According to the listing, 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 stated resolution source is the ETH/USD TWAP data stream from Chainlink, and the rules say the market is about that stream and not about other sources or spot markets [1]. The timing matters for reading the contract. The listing records an observation time of 2026-10-26T15:00:05Z and a retrieval time of 2026-10-26T17:45:40Z, and it gives a listed end time of 2026-10-27T11:30:00Z [1]. Those are different moments. The observation time is when the provider data was captured, the retrieval time is when this record was collected, and the listed end time is the scheduled close of the contract. The source describes the status at retrieval as active [1]. Nothing in the evidence shows how the contract finally resolved, so the outcome should be treated as unknown here. At the observation time, the saved snapshot showed the Up outcome at 0.505 and the Down outcome at 0.495 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities of either result.
Why It Matters
The contract measures the direction of the Ether price over a single five-minute window, using a time-weighted average from one named data stream. Because the comparison is between the average over the window and the price at the start of the window, the result depends on the feed's averaging method and not simply on the last trade shown elsewhere [1]. The rules state that other sources and spot markets do not determine the result [1], so readers should check the named Chainlink stream when interpreting the contract. The short window also means the contract is sensitive to timing: the listed end time falls after the observation and retrieval times, so the snapshot prices reflect the market at one earlier moment [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-26 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 determines whether this market resolves Up or Down?
The market resolves Up if the Chainlink ETH/USD time-weighted average price over the title's time range is greater than or equal to the price at the beginning of that range. Otherwise it resolves Down [1].
Which price source is used for resolution?
The stated resolution source is the ETH/USD TWAP data stream available from Chainlink, and the rules say other sources or spot markets are not used [1].
What does the listed end time mean?
The listing gives an end time of 2026-10-27T11:30:00Z for the contract [1]. This is the scheduled close recorded in the contract data, not evidence of how or when the market was finally settled.
Do the displayed prices show the chance that Ether goes up?
The saved snapshot showed Up at 0.505 and Down at 0.495 at the observation time [1]. These are snapshot prices, not executable quotes or verified probabilities, so they should not be read as a confirmed chance of either result.
