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 is titled "Ethereum Up or Down - October 19, 10:05PM-10:10PM ET" [1]. Its 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 a different ether price market should check whether that market uses the same data source, averaging method, and time window. Wording differences like these can change what a given price is measuring.
The provider lists an end time of 2026-10-20T02:10:00.000Z [1]. That is the listed close time, not a record that the market has resolved. The provider status in the saved excerpt is "active" [1].
Reading the snapshot
The saved market shows two outcomes: "Up" at 0.505 and "Down" at 0.495 [1]. These are snapshot prices from a provider observation at 2026-10-19T03:00:06.086Z, retrieved by PredictPedia at 2026-10-19T04:10:53.271Z [1]. The observation is therefore about 71 minutes older than the retrieval, and both times are earlier than any later reading. Prices may have changed since then, and this snapshot should not be read as a current price.
The two prices sum to 1.000, and the snapshot does not indicate why they sit where they do. Because these are not executable quotes, they do not show what a trader could buy or sell at, and they are not verified probabilities. The saved data also does not include volume or trader counts, so it says nothing about liquidity or how many participants hold each view.
Coverage is limited to one market from one event. The sample is marked as not partial, and the saved data includes all markets for this event [1]. However, the sample warning states that this "does not establish that the providers list every possible real-world outcome" [1]. Since this is a binary Up or Down contract, the two listed outcomes are the full set in the saved data.
What remains uncertain
The evidence does not show the final result, the price at the start of the time range, or the TWAP value during the window. It also does not establish whether the market has settled. A reader should not treat the 0.505 price as a forecast of the outcome. Any comparison with other ether markets should be limited to contracts with matching rules, close times, and data sources, rather than combining prices across different events.

Saved Oct 19, 2026 UTCOverview
This contract, titled "Ethereum Up or Down - October 19, 10:05PM-10:10PM ET", is a short-window market listed on Polymarket in the Crypto category [1]. It asks whether the price of Ethereum will be higher or lower over a five-minute range, measured against the price at the start of that range. The listed end time is 2026-10-20T02:10:00.000Z, which corresponds to 10:10 PM ET on October 19 [1]. The contract 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 market is therefore about direction relative to the starting price, not about a specific dollar target. The resolution source is Chainlink's ETH/USD TWAP data stream, identified as the 60-second ETH/USD TWAP stream [1]. The rules state that the market concerns the price in that Chainlink data stream only, and not the price reported by other sources or spot markets [1]. A reader comparing this contract with an exchange price chart should keep that distinction in mind, because the two may not match exactly. At the observation time recorded for this snapshot, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These are snapshot prices from the provider, not executable quotes, and they are not verified probabilities of what will happen. The provider lists the market as active at that time [1].
Why It Matters
The contract measures whether Ethereum's TWAP over a specific five-minute window, as reported by Chainlink's ETH/USD TWAP data stream, finishes at or above the price at the start of that window [1]. Because the outcome depends on a specific data stream rather than on general market prices, the rules define exactly which number decides the result [1]. Anyone reading the 0.505 and 0.495 prices should understand they reflect trading in this contract at the snapshot time, not a forecast verified by the provider.

Frequently Asked Questions
What does the contract ask?
It asks whether the Chainlink ETH/USD TWAP over the 10:05 PM to 10:10 PM ET window on October 19 will be greater than or equal to the price at the beginning of that window [1].
Which price decides the outcome?
The outcome is based on the ETH/USD TWAP data stream from Chainlink, not on other sources or spot markets [1].
What happens if the TWAP equals the starting price?
The rules say the market resolves to Up when the TWAP is greater than or equal to the starting price, so an equal value resolves Up [1].
What do the Up and Down prices show?
At the recorded snapshot, Up was priced at 0.505 and Down at 0.495 [1]. These are provider snapshot prices for this contract and do not establish an executable trade or a verified probability.
