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 contract, "Ethereum Up or Down - October 28, 1:00PM-1:15PM ET," in the Crypto category [1]. It 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 resolution source is the Chainlink ETH/USD TWAP data stream. The rules state 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]. A reader comparing this contract with an ETH price elsewhere should note that a different source or a spot price could move differently from this measure.

The listed end time is 2026-10-28T17:15:00.000Z [1]. The title uses Eastern Time, so readers should convert the two formats before relying on either one. This listed close time is when the contract stops trading, not a confirmed resolution time.

Reading the snapshot

The provider observed this market at 2026-10-27T21:00:06.613Z, and the record was retrieved at 2026-10-27T21:10:17.327Z [1]. These are times for this saved record only. The provider status was active at observation [1]. Prices may have changed since then, and this text does not describe current conditions.

The saved prices are "Up" at 0.505 and "Down" at 0.495 [1]. These are snapshot prices, not executable quotes, and they are not verified probabilities. The two prices sum to 1.00 in this record. The sample includes the single market for this event, with no partial sampling indicated [1]. Because only one market is present, no cross-platform comparison is possible from this evidence.

The supplied data does not show trading volume, liquidity, or the number of participants, so this snapshot cannot be used to judge depth or consensus.

What remains uncertain

The supplied evidence does not explain why the prices stand where they do. It also does not state the price of Ethereum at the start of the range or any later value, so the outcome cannot be determined from this record. The contract has not resolved according to the supplied evidence.

Overview

This is a short-term crypto market on Polymarket asking whether Ethereum will go up or down over a fixed window. The event is titled "Ethereum Up or Down - October 28, 1:00PM-1:15PM ET" and sits in the Crypto category [1]. The title gives the window in Eastern Time, while the listed end time in the provider record is 2026-10-28T17:15:00.000Z [1]. The rules say 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 comparison is therefore between an average over the window and the starting price, not between the price at the end and the start. The resolution source is Chainlink's ETH/USD TWAP data stream, and the rules state that only this Chainlink data counts, not other sources or spot markets [1]. Traders pricing the contract are therefore reasoning about that specific feed. The provider record lists the event as active [1].

Why It Matters

The contract measures whether the Chainlink ETH/USD TWAP over a 15 minute window is at or above the price at the start of that window [1]. Because the average is compared with the opening price, the outcome depends on the path of the average within the window rather than only the final price. Anyone reading the contract should check the exact resolution feed named in the rules, since the market explicitly excludes other sources and spot markets [1].

Snapshot context

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

Frequently Asked Questions

What decides whether the market resolves Up or Down?

It resolves Up if the Chainlink ETH/USD TWAP over the stated time range is greater than or equal to the price at the beginning of that range. Otherwise it resolves Down [1].

Which data source is used for resolution?

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

Does the time in the title match the listed end time?

The title gives the window as 1:00PM to 1:15PM ET, and the provider record lists the end time as 2026-10-28T17:15:00.000Z [1]. Readers should compare the two time formats directly when checking the window.
