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 event asks whether the Ethereum price will rise or fall over a specific five-minute window. According to the provider's rules, the 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"" [1]. The rules name the resolution source as the ETH/USD TWAP data stream 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]. Any comparison with other Ethereum prices or exchanges would therefore reflect a different measure.
The listed end time is 2026-10-31T03:30:00.000Z [1]. In the title's Eastern time, this corresponds to 11:30 PM ET on October 30. The contract rules define the outcome by this window, so the listed time is the close of the window, not a separate announcement.
Reading the snapshot
The saved snapshot was observed at 2026-10-30T21:00:05.889Z and retrieved at 2026-10-31T00:00:15.923Z [1]. The prices below describe the observation time, not the time you are reading this.
- Up: 0.505
- Down: 0.495
These are the only two outcomes in the saved market. The snapshot shows a narrow gap between them, with Up slightly higher. These are quoted snapshot prices, not executable quotes, and they are not verified probabilities. The sample contains one market from one platform, so no cross-platform comparison is possible. Because only one provider event is included, the sample also says nothing about other Ethereum contracts with different windows or wording.
What remains uncertain
The evidence does not include trading volume, order book depth, or the number of participants, so it cannot show how liquid the market was or how many traders held either view. The snapshot also cannot explain why the prices sat where they did. It does not show whether the status changed after observation. Readers should check the provider page for the latest status and prices before drawing any conclusion.

Saved Oct 31, 2026 UTCOverview
This PredictPedia entry covers a short-term crypto contract on Polymarket titled "Ethereum Up or Down - October 30, 11:25PM-11:30PM ET." The contract asks whether the price of Ether (ETH) over a five-minute window will finish at or above its starting level. According to the contract rules, the market 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 measurement is specific. The rules name the ETH/USD TWAP data stream from Chainlink as the resolution source, and state that the market concerns the price according to that Chainlink stream for the ETH/USD pair, not other sources or spot markets [1]. A trader reading the contract therefore needs to know which data feed decides the outcome, not simply where Ether is trading elsewhere. The saved record has three distinct times. The provider observation was recorded at 2026-10-30T21:00:05Z, the source was retrieved at 2026-10-31T00:00:15Z, and the listed end time for the contract is 2026-10-31T03:30:00Z [1]. The observation and retrieval times describe when this data was captured, not the current state of the market. The listed end time is the close of the stated window as written in the contract, which is not evidence that the market has resolved or of any particular outcome. The provider status recorded in the saved source was active at the time of retrieval.
Why It Matters
The contract measures the direction of Ether's price over a single five-minute window, as defined by the Chainlink ETH/USD TWAP data stream [1]. Because the outcome depends on a time-weighted average compared with the starting price, a short window can be affected by how the price moves within the interval, not only by its endpoints [1]. The rules also limit the measurement to that one data stream, so the contract reflects that feed's reported values rather than a general consensus on Ether's price [1]. Readers should treat the displayed outcome prices as a snapshot of market pricing at a point in time, not as a verified probability of the result.
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-30 at 21:00 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
What determines whether this market resolves to Up or Down?
The market resolves to "Up" if the Chainlink ETH/USD TWAP over the stated time range is greater than or equal to the price at the start of that range. Otherwise it resolves to "Down" [1].
Which price source is used for resolution?
The resolution source is the ETH/USD TWAP data stream from Chainlink. The rules state that prices from other sources or spot markets are not used for this contract [1].
Does the listed end time mean the market has already resolved?
The listed end time, 2026-10-31T03:30:00Z, is the date recorded in the contract data for the close of the stated window [1]. The supplied evidence does not show the resolution outcome, so the end time should not be read as a report that the market has settled.
