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
The supplied contract is "Ethereum Up or Down - October 16, 4:35AM-4:40AM ET" on Polymarket [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 source adds 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]. A reader comparing this contract with another venue's ETH market should check whether that market uses the same data stream, averaging method, and time window.
The listed end time is 2026-10-16T08:40:00.000Z [1]. That is the contract's listed close, not a confirmed resolution. The evidence does not show a resolution outcome.
Reading the snapshot
The record was observed at 2026-10-15T16:13:13.851Z and retrieved at 2026-10-15T18:54:35.541Z. These are different times, and the observation is the one that matters for the prices. The saved quote shows "Up" at 0.505 and "Down" at 0.495 [1]. These are snapshot prices from a single market. They are not executable quotes, and they are not verified probabilities.
The sample covers one market from one platform. The coverage record lists one total market and one included market, with no partial sampling [1]. This means no other outcomes were omitted from this event. The sample warning, however, states that this "does not establish that the providers list every possible real-world outcome" [1]. Since the contract is binary, the two prices are the only outcomes in the record.
The record includes no volume or trader count, so it says nothing about liquidity or how many participants hold each side.
What remains uncertain
The snapshot is about 2 hours and 40 minutes older than the retrieval time, and the evidence contains no later price. Prices may have changed since observation. The record does not explain any movement, and it contains no news or context about the market.
Comparing this contract with a market on another platform would require matching both the rule wording and the close time. A difference in price between two contracts with different rules is not, by itself, an arbitrage opportunity.

Saved Oct 15, 2026 UTCOverview
This PredictPedia entry covers a short-window Ethereum price contract listed on Polymarket. The event is titled Ethereum Up or Down for the window from 4:35 AM to 4:40 AM ET on October 16, and the provider lists it as active [1]. The contract is about a price window rather than a fixed price target. It resolves to Up if the time-weighted average price of Ethereum over the stated window is greater than or equal to the price at the beginning of that window. If not, it resolves to Down [1]. The resolution source is Chainlink. The contract points to the ETH/USD TWAP data stream with a 60-second interval [1]. The provider states that the market concerns the price shown in that Chainlink data stream for the ETH/USD pair, and not any other data source or spot market [1]. This matters because two sites quoting Ether at similar moments may still differ from the resolution figure, which is the stream the contract names. The listed end time is 2026-10-16T08:40:00Z, which corresponds to the close of the 4:40 AM ET window [1]. That end time is a contract closing time. It is not a separate announced event or a deadline for anything beyond the window itself.
Why It Matters
The contract measures the direction of Ethereum's ETH/USD price over one five-minute window, as recorded by a specific Chainlink TWAP stream [1]. Because the outcome depends on an average over the window compared with the price at the start, the contract does not simply ask whether the price ends higher than it began. Its settlement depends on the averaged data stream the rules name [1]. Anyone reading a price for this contract should keep in mind that the figure reflects the provider's snapshot and is not an executable quote.
