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, titled "Ethereum Up or Down - October 28, 12:50AM-12:55AM ET," resolves based on a Chainlink price feed rather than a general market price [1]. The saved rules say 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 ETH/USD TWAP data stream from Chainlink. The rules 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] A reader comparing this contract with an Ethereum contract on another platform should check whether that contract uses the same source, window, and comparison rule.

The listed end time is 2026-10-28T04:55:00.000Z [1]. This is a closing time in the contract record. It is not evidence of how or when the market resolved, and the supplied evidence does not show a resolved outcome.

Reading the snapshot

The provider observed the market at 2026-10-27T06:00:05.981Z, and the saved record was retrieved at 2026-10-27T08:14:11.619Z [1]. These are different timestamps. The prices describe the observation time, not the time you are reading this.

At observation, the Up outcome was priced at 0.505 and the Down outcome at 0.495 [1]. These are snapshot prices, not executable quotes or verified probabilities. The 0.010 difference between them reflects only that single observation.

The saved coverage includes one Polymarket market for this event, and the record indicates it is not a partial sample [1]. That covers this event only. It does not establish that the provider lists every possible outcome for other Ethereum windows or other platforms.

What remains uncertain

The evidence does not explain why prices were at these levels, and it includes no information on trader counts, recent developments, or forecasting track record. The stored provider status was "active" at retrieval [1], but the prices may have changed since the observation time, and no later price is supplied.

Comparisons with other Ethereum contracts should be limited to markets with matching time windows, price sources, and closing times. Differences in those terms mean the prices do not measure the same event.

Overview

This is a short-term Polymarket contract on the direction of Ethereum's price over a five-minute window. The title is "Ethereum Up or Down - October 28, 12:50AM-12:55AM ET", and the contract is categorized as Crypto [1]. The market resolves to "Up" if the time-weighted average price (TWAP) of Ethereum over the window named in the title is greater than or equal to the price at the beginning of that window. Otherwise it resolves to "Down" [1]. The contract specifies that the price source is Chainlink's ETH/USD TWAP data stream, identified in the rules as a 60-second TWAP stream [1]. The rules state that the market concerns the price in that Chainlink data stream for the ETH/USD pair, not the price reported by other sources or spot markets [1]. Traders reading the contract should therefore focus on that specific feed rather than on general Ethereum price headlines. The listed end time is 2026-10-28T04:55:00.000Z, and the provider lists the event as active [1]. The title's ET window and the listed UTC end time describe the same contract period as written in the provider's materials [1]. The end time is a contract closing time, not an announced event, and it does not by itself indicate when resolution data will be published. In the saved snapshot, the "Up" outcome was priced at 0.505 and the "Down" outcome at 0.495 [1]. These figures were observed at 2026-10-27T06:00:05.981Z and are a record of that moment only. They are not executable quotes and are not verified probabilities.

Why It Matters

The contract measures whether the Chainlink ETH/USD TWAP over the stated five-minute window finishes at or above its starting value [1]. Because the rule compares the window's average price with the price at the start of the window, the outcome depends on the averaged data stream rather than a single printed price at the end [1]. Its short duration and reliance on one named data feed make the rules the central point for interpreting the contract [1].

Snapshot context

The latest published provider snapshot for this topic was observed on 2026-10-27 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.

Frequently Asked Questions

How does this Ethereum contract decide whether it resolves Up or Down?

It resolves to "Up" if the TWAP of Ethereum over the window in the title is greater than or equal to the price at the beginning of that window, and to "Down" otherwise [1].

Which price source determines the outcome?

The resolution source is the Chainlink ETH/USD TWAP data stream, and the rules say other sources or spot markets do not determine the result [1].

What time window does the contract cover?

The title gives a window of 12:50AM to 12:55AM ET on October 28, and the listed end time is 2026-10-28T04:55:00.000Z [1].
