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 market asks whether Ethereum's price will rise or fall over a fixed 15-minute window. According to the rules, 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 title gives the window as "October 26, 5:30AM-5:45AM ET" [1].
The resolution source is specific. The rules name "the ETH/USD TWAP data stream" from Chainlink and state that 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]. A reader comparing this contract with a spot price chart or another platform's Ethereum contract should check whether that contract uses the same source, window, and comparison rule.
The listed end time is 2026-10-26T09:45:00.000Z [1]. This is the contract's closing time, not a confirmed resolution. The evidence does not show how or when the market resolved.
Reading the snapshot
The saved observation was taken at 2026-10-25T12:00:06Z, and the source was retrieved at 2026-10-25T12:35:51Z [1]. The prices below describe that observation only. They are not live quotes and may differ from prices shown now.
The snapshot shows "Up" at 0.505 and "Down" at 0.495 [1]. Read as snapshot prices, these are close to an even split, with "Up" slightly higher. Prices are not executable quotes, and they are not verified probabilities. The evidence contains no volume or trade data, so it cannot show how much liquidity sits behind either price or how many participants are involved.
The sample covers the only market saved for this event. Coverage shows one market, all included, with no partial sample [1]. Because this is a binary contract, the two outcomes are the full set of results for this window.
What remains uncertain
The evidence does not explain why prices were at these levels, and this analysis does not attribute any movement to news or events. It also does not show whether the price has changed since the observation.
The contract's wording, resolution source, and closing time are specific to this 15-minute window. A similar Ethereum contract on another platform, or a different time window, is not directly comparable even if the labels look alike. Any difference in price between such contracts should not be treated as an arbitrage opportunity without checking their rules, timing, and execution conditions.

Saved Oct 25, 2026 UTCOverview
This contract is a short-window price market for Ethereum, titled "Ethereum Up or Down - October 26, 5:30AM-5:45AM ET". It is listed on Polymarket as an active event in the crypto category [1]. Its outcomes are "Up" and "Down", and the contract is about whether the price of ETH moves up or down over one fifteen-minute window. The rules say the market 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 window is therefore compared with its own starting price, not with a price from some other time or a different market. The named resolution source is Chainlink's ETH/USD TWAP data stream, described as a 60-second TWAP stream [1]. The rules state that only this Chainlink data stream counts, and not other sources or spot markets [1]. A trader reading the contract therefore needs to know what that specific feed reports, rather than the price shown on a general exchange. The listed end time is 2026-10-26T09:45:00Z [1]. The saved snapshot of the contract was observed at 2026-10-25T12:00:06Z, and the outcome prices in that snapshot were Up at 0.505 and Down at 0.495. These are the prices recorded in that snapshot only. They are not executable quotes, they are not verified probabilities, and they do not describe the market at any later time.
Why It Matters
The contract measures the direction of Ethereum's price over a single fifteen-minute window, using a time-weighted average from one named data feed. Because the comparison is between the window's average and the price at its start, the result depends on how the TWAP behaves within the window, not only on where the price ends [1]. The rules also tie the outcome to the Chainlink data stream alone, so the contract's result is defined by that feed rather than by any other price series [1].
