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 event, "Ethereum Up or Down - October 27, 10:00AM-10:05AM ET" [1]. The contract 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 source names the ETH/USD TWAP data stream as the resolution source and states 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].
The title is written in ET, while the listed end time is given in UTC as 2026-10-27T14:05:00.000Z [1]. Readers should convert the times before comparing this contract with others. The listed end time is a contract closing time, not a record of when the market was resolved. The evidence does not show a resolution.
Reading the snapshot
The provider observed the market at 2026-10-26T18:00:06.173Z, and this assistant retrieved the saved record at 2026-10-26T19:16:25.831Z [1]. The prices below describe the observation time only, not the present.
At observation, the outcome "Up" was priced at 0.505 and "Down" at 0.495 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The evidence does not include volume, order book depth, or trader counts, so it says nothing about liquidity or how many participants hold either view.
The sample covers one market from one provider event. The coverage record shows one total market, one included, and no partial sample [1]. Because this is the complete saved set for this event, no omitted outcome needs to be considered. The evidence does not establish that the provider lists every possible outcome for this real-world question, but no other outcomes appear in the record.
What remains uncertain
The evidence does not explain why either price is where it is. It also does not provide any other platform's pricing for a comparable contract. A difference in prices across platforms would not by itself indicate an opportunity, since wording, resolution sources, and closing times can differ.
Because the record was observed roughly 1 hour and 16 minutes before retrieval, and the listed end time falls later, any later price may differ from the snapshot shown here.

Saved Oct 26, 2026 UTCOverview
This is a short-window binary contract on Ethereum's price, listed on Polymarket under the title Ethereum Up or Down - October 27, 10:00AM-10:05AM ET [1]. The contract covers a five-minute window. According to the listed rules, it resolves to Up if the time-weighted average price (TWAP) of Ethereum over that window is greater than or equal to the price at the beginning of the window. Otherwise it resolves to Down [1]. The measurement is based on a specific data feed rather than general market prices. The resolution source is information from Chainlink, specifically the ETH/USD TWAP data stream [1]. The rules state that the market concerns the price according to that Chainlink stream for the ETH/USD pair, and not according to other sources or spot markets [1]. Anyone reading the contract should therefore check the Chainlink feed, not a general exchange price, to understand how the outcome is determined. The listed end time for the contract is 2026-10-27T14:05:00.000Z [1]. That timestamp marks when the window closes, which is distinct from the time the market is resolved or paid out. The contract is listed as active in the saved event record [1]. In the saved snapshot, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These are snapshot values from the time the event record was retrieved. They are not executable quotes, and they are not verified probabilities of the outcome.
Why It Matters
The contract measures whether the Chainlink ETH/USD TWAP over a five-minute window, from 10:00 to 10:05 AM ET on October 27, finishes at or above the price at the start of that window [1]. Because the outcome depends on an average over the window compared with a starting price, it is not simply a test of where Ethereum trades at the end. The contract also limits the source to one data stream, so readers should understand that a different feed or exchange price could show a different result [1].
