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 titled "Ethereum Up or Down - October 20, 1:15AM-1:20AM ET" in the Crypto category [1]. The rules state that 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 named resolution source is the ETH/USD TWAP data stream, and the provider notes 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].
Because the outcome depends on a Chainlink TWAP rather than a spot price, a reader should not compare this contract with an Ethereum price market that uses a different source or time window. The listed end time is 2026-10-20T05:20:00.000Z [1].
Reading the snapshot
The saved snapshot was observed at 2026-10-19T06:00:06Z and retrieved at 2026-10-19T06:57:33Z [1]. It shows the following prices:
- Up: 0.505
- Down: 0.495
These figures are a single observation from that observation time. They are not executable quotes, and they are not verified probabilities. The two prices sum to 1.00 in this record, which is consistent with a binary pair. Because the snapshot is nearly balanced, the difference between the outcomes is small, but the record does not explain why the prices stand where they do.
The sample covers one market from one provider event. The coverage record shows one total market, one included market, and no partial sample [1]. Even so, the provider notes that the saved list "does not establish that the providers list every possible real-world outcome" [1]. This snapshot therefore says nothing about other Ethereum contracts, other platforms, or other time windows.
What remains uncertain
The evidence does not include trading volume, liquidity, number of participants, or any later price. It also does not include the actual TWAP values at the start or end of the window, so the resolution outcome is not known from this record. The contract's status was "active" at retrieval [1].
Readers should check the provider page for current prices and status, since this snapshot describes a past observation and not present conditions.

Saved Oct 19, 2026 UTCOverview
This PredictPedia entry covers a crypto price contract on Polymarket titled "Ethereum Up or Down - October 20, 1:15AM-1:20AM ET" [1]. The contract asks whether Ethereum's price will be higher or lower over a specific five-minute window, 1:15 to 1:20 AM Eastern Time on October 20. The listed end time is 2026-10-20T05:20:00Z [1]. The contract 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 comparison is therefore between an average across the window and a single starting price, not between the price at the start and the price at the end. The contract specifies its resolution source as Chainlink data, specifically the ETH/USD TWAP data stream [1]. The rules state that the market concerns the price in that Chainlink stream and not the price from any other source or spot market [1]. A reader comparing this contract with an exchange price chart should expect that the two may differ. In the saved snapshot, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These figures are prices observed at the time the event was recorded, not executable quotes or verified probabilities. The event is the only market in this sample, and the sample is complete for that event.
Why It Matters
The contract measures whether the average Ethereum price over a five-minute window, as reported in a specific Chainlink TWAP data stream, finishes at or above the price at the start of that window [1]. Because the outcome depends on that particular data stream and not on general market prices, the rules define exactly which price series counts. The displayed Up and Down prices reflect what participants were paying for each outcome at the observation time, which is a useful but limited indicator of market sentiment rather than a confirmed forecast [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-19 at 06:00 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 does an "Up" outcome mean for this contract?
The market resolves to "Up" if the time-weighted average price of Ethereum over the 1:15 to 1:20 AM ET window, as generated by Chainlink, is greater than or equal to the price at the beginning of that window [1].
Which price source determines the result?
The resolution source is the ETH/USD TWAP data stream from Chainlink. The rules state that other sources and spot markets are not the basis for resolution [1].
Does a price near 0.50 mean one outcome is more likely?
The saved prices were 0.505 for Up and 0.495 for Down at the observation time [1]. These are snapshots of trading prices, not verified probabilities, so they should not be read as a forecast of the result.
