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 short-window contract from Polymarket on Ethereum's price direction. 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 window in the title is 10:50AM to 10:55AM ET.
The resolution source is specified narrowly. The rules name "the ETH/USD TWAP data stream" from Chainlink and say 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]. A reader comparing this contract with an ETH price quoted elsewhere should not treat the two as the same measurement.
The provider lists an end time of 2026-10-22T14:55:00.000Z [1]. That is the listed close, not a confirmed resolution. The source excerpt does not report an outcome.
Reading the snapshot
The saved observation is timestamped 2026-10-22T00:00:05.980Z, and the source was retrieved at 2026-10-22T03:48:34.782Z [1]. These are different times. The prices below describe the saved observation, not the market at the moment you read this.
In that observation, the "Up" outcome was priced at 0.505 and "Down" at 0.495 [1]. These are snapshot prices. They are not executable quotes, and they are not verified probabilities. The contract's status at retrieval was "active" [1].
The sample covers one market from one provider event. The coverage record shows one total market, one included market, and no partial sampling [1]. Because only two outcomes exist in this binary contract, no omitted outcome affects the comparison. The reported volume is not provided in this evidence, so nothing can be inferred about liquidity or the number of traders.
No other platform's contract appears in this evidence. A price difference between this contract and a differently worded contract would not establish an opportunity, because their rules may measure different things.
What remains uncertain
The evidence does not show why the snapshot prices are where they are. It also does not show any price after the observation time, or the outcome once the window closed. The retrieved excerpt does not include recent news or any explanation for market movement, and none is offered here.
The 0.505 and 0.495 figures are near even, but that observation alone does not indicate which outcome is more likely. Readers should check the rules text directly, note the ET window and the UTC listed end time, and consult the provider for any later status or resolution.

Saved Oct 22, 2026 UTCOverview
This PredictPedia entry covers a short-term crypto contract titled "Ethereum Up or Down - October 22, 10:50AM-10:55AM ET" on Polymarket. The contract asks whether the price of Ether (ETH) will rise or fall over one five-minute window on October 22, 2026, from 10:50 to 10:55 AM Eastern Time. The listed end time is 14:55 UTC on that date [1]. The rules tie resolution to a time-weighted average price, or TWAP. Under the rules, the market resolves to "Up" if the TWAP over the time range in the title is at or above the price at the start of that range. Otherwise it resolves to "Down" [1]. The contract therefore compares an averaged price during the window with the starting price, rather than comparing the price at the close with the price at the open. The resolution source is the ETH/USD TWAP data stream published by Chainlink, with a 60-second TWAP referenced in the source [1]. The rules state that only this Chainlink data stream counts. Other exchanges or spot markets do not determine the outcome [1]. The source record was observed at 00:00:05 UTC on October 22, 2026, and retrieved at 03:48:34 UTC the same day. At retrieval, the provider reported the contract as active [1]. Because the window closes later on the same day, the contract's outcome depends on data that falls after the retrieval time. This entry describes the rules and does not report how the contract resolved.
Why It Matters
The contract measures whether Ether's Chainlink-based TWAP over a five-minute window finishes at or above its starting level. Because the reference is an average over the window, a single price spike near the end of the window does not by itself determine the result. The rules also mean that Ether prices on other venues do not decide the outcome [1]. Anyone reading a price for this contract should keep in mind that the rules define the event narrowly, so the quoted figure reflects expectations about that specific reference rather than about Ether's price in general [1].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-22 at 00:00 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

The contract resolves Up if the time-weighted average price 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 Down [1].
Which price data is used for resolution?
The resolution source is the ETH/USD TWAP data stream from Chainlink, with the rules pointing to a 60-second TWAP stream. The rules state that other sources or spot markets are not used [1].
When does the contract's measurement window end?
The listed end time is 14:55 UTC on October 22, 2026, which corresponds to the close of the 10:50 to 10:55 AM Eastern Time window named in the title [1].
