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 contract asks whether the Ethereum price will rise or fall during a fixed window. The title is "Ethereum Up or Down - October 26, 5:15PM-5:30PM ET" [1]. The rules state that 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 Chainlink ETH/USD TWAP data stream, and the rules say 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]. A reader comparing this contract with another ether market should check whether that market uses the same data source, averaging method, and window, since a different wording could resolve differently even with a similar title.
The listed end time is 2026-10-26T21:30:00.000Z [1]. That is the listed close time for trading, not the time the outcome was determined.
Reading the snapshot
The saved snapshot was observed at 2026-10-26T00:00:05.974Z and retrieved at 2026-10-26T02:44:47.868Z [1]. Both times are earlier than the listed end time. The prices below describe the saved observation only and should not be read as current prices.
- Up: 0.505
- Down: 0.495
These are snapshot prices, not executable quotes or verified probabilities. A reader should not treat them as the likelihood of a rise, since they come from one observation of one contract. The Up and Down prices are close to each other in this snapshot, which only describes the saved values.
The sample covers one market from one platform. The coverage record shows one total market, one included market, and no partial sample [1]. Because the sample includes only this contract, no comparison with other platforms or events is possible from this evidence.
What remains uncertain
The evidence does not explain why the prices were where they were at observation, and it does not show trading volume, liquidity, or the number of participants. It also contains no information about the Ethereum price during the window, since the saved excerpts only describe the rules and the snapshot. The evidence does not say what the outcome will be.
The source describes the market as "active" with a listed end time [1]. Anyone relying on this snapshot after the observation time should retrieve a newer record before drawing conclusions.

Saved Oct 26, 2026 UTCOverview
This PredictPedia entry covers a short-window price contract titled "Ethereum Up or Down - October 26, 5:15PM-5:30PM ET", listed on Polymarket in the Crypto category [1]. The contract asks whether the price of Ethereum will move up or down over a fifteen-minute window. It resolves to "Up" if the time-weighted average price (TWAP) of Ethereum 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 price comes from Chainlink, not from general market trading. The source states that the resolution is based on Chainlink's ETH/USD TWAP data stream and that the market concerns the price in that Chainlink stream, not prices from other sources or spot markets [1]. Traders reading the contract should therefore check the Chainlink stream definition rather than a price shown on a different exchange or website. The saved event lists one market with two outcomes, Up and Down. At the observation time recorded for this entry, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These are snapshot values from a single record. They are not executable quotes, and they should not be read as verified probabilities. The listed end time for the contract is 2026-10-26T21:30:00Z, and the provider reported the market as active when the record was retrieved [1]. That end time is a contract closing time. It is not a claim about when the price will move or when any result will be published.
Why It Matters
The contract measures whether the Chainlink ETH/USD TWAP over the fifteen-minute window in the title finishes at or above the TWAP level at the start of that window [1]. Because it compares the average over the window with the starting price, it is about direction within a short period rather than a fixed price target. The Chainlink data stream is the defined reference, so the outcome depends on that feed and not on other markets [1]. The Up and Down prices in the saved record show how the market was priced at one moment, which can help a reader see the market's view at that time, but the record does not explain why those prices existed [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-26 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
How does this contract decide whether it resolves Up or Down?
It compares the Chainlink ETH/USD time-weighted average price over the time range in the title with the price at the beginning of that range. If the average is greater than or equal to the starting price, the contract resolves Up. Otherwise it resolves Down [1].
Which price source determines the outcome?
The resolution source is the Chainlink ETH/USD TWAP data stream. The source states that prices from other sources or spot markets are not the basis for this contract [1].
Does the price shown for Up or Down mean the event is likely to happen?
The saved record shows 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 do not establish how likely either outcome is.
