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 contract is a Polymarket event titled "Ethereum Up or Down - October 28, 11:35AM-11:40AM ET" [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 resolves to "Down" [1].

The named resolution source is the ETH/USD TWAP data stream, and the rules say 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]. The listed end time is 2026-10-28T15:40:00.000Z [1]. This is a scheduled close recorded in the contract, not evidence that the market has resolved.

Reading the snapshot

The saved snapshot was observed at 2026-10-27T18:00:06.010Z and retrieved at 2026-10-27T18:34:15.970Z [1]. At observation, Polymarket showed Up at 0.505 and Down at 0.495, with the provider status listed as active [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The two outcomes sum to 1.000, so the snapshot prices only these two outcomes.

The saved record includes no volume or liquidity figures, so it says nothing about depth or the number of participants. The sample contains one market from one platform. All saved markets for this event are included, and the sample is not partial [1]. That does not establish that the provider lists every possible outcome. No other platform's contract appears in the evidence, so no cross-platform comparison is possible.

What remains uncertain

The snapshot was taken about 34 minutes before retrieval and about 21 hours before the listed end time, so it does not show current prices. The evidence does not explain why the prices are where they are. Because resolution depends on the Chainlink ETH/USD TWAP stream, prices or price reports from other sources would not determine this contract's outcome. The evidence does not show how the contract will resolve.

Overview

This market is a short-window contract on the price of Ethereum in US dollars. Its title, Ethereum Up or Down - October 28, 11:35AM-11:40AM ET, identifies a five-minute window on October 28. The contract is listed on Polymarket and was marked active when the saved record was observed at 2026-10-27T18:00:06Z [1]. The contract 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 rule therefore compares an average over the window with the starting price, not the price at a single moment near the end. The source specifies which price feed counts. The resolution source is the ETH/USD TWAP data stream published by Chainlink, and the source states that the market concerns the price in that Chainlink data stream rather than other sources or spot markets [1]. Anyone reading a price from a different exchange or data feed would be looking at a different measure than the one the contract uses. At the observation time, the saved record showed "Up" at 0.505 and "Down" at 0.495 [1]. These figures are snapshots of the listed prices at that moment. They are not executable quotes, and they do not by themselves represent a verified probability of either outcome.

Why It Matters

The contract measures the direction of Ethereum's price across a short, fixed window. Because the comparison uses a time-weighted average rather than a single trade, brief spikes at the end of the window carry less weight than a sustained move, and the reference point is the price at the window's start [1]. The contract is tied to one named data stream, which means its result is defined by that feed's values rather than by general market consensus [1].

Snapshot context

The latest published provider snapshot for this topic was observed on 2026-10-27 at 18:00 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

What counts as an "Up" result?

An "Up" result requires the Chainlink ETH/USD TWAP over the stated window to be greater than or equal to the price at the beginning of that window [1].

Which price source determines the outcome?

The resolution source is the ETH/USD TWAP data stream from Chainlink, and the contract is explicitly about that stream rather than other sources or spot markets [1].

Does the contract settle at the end of the window or at a single moment?

The rule uses the time-weighted average over the window in the title, compared with the price at the start of that window. The listed end time for this contract is 2026-10-28T15:40:00.000Z [1].
