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 supplied contract is "Ethereum Up or Down - October 31, 10:40AM-10:45AM ET" on Polymarket [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 ETH/USD TWAP data stream from Chainlink, not other sources or spot markets [1]. The listed end time is 2026-10-31T14:45:00.000Z [1]. That is the contract's closing time, not a record of resolution. The supplied evidence does not show how or when the contract resolved.

Reading the snapshot

The provider observed the market at 2026-10-30T21:00:05.889Z. The retrieval record is dated 2026-10-31T02:45:35.675Z [1]. Both times describe when the data was collected, so the prices below describe that earlier observation and should not be read as live prices.

At observation, the saved prices were 0.505 for "Up" and 0.495 for "Down" [1]. These are snapshot prices. They are not executable quotes, and they are not verified probabilities. The evidence also includes no volume figures, so it says nothing about liquidity or how many traders were involved.

The sample covers one market from one provider event. The coverage record shows one total market and one included market, with no partial sample [1]. Because only this single contract appears, there is no cross-platform or multi-contract comparison to make. The sample also does not establish that Polymarket lists every possible outcome for this event.

What remains uncertain

The evidence does not explain why the prices were where they were at observation. It also does not show any later prices, any resolution outcome, or whether the prices have changed since retrieval. Readers comparing this contract with a similar one on another platform should check each contract's wording, source, and listed close time separately, since the supplied evidence contains only this one contract.

Overview

This market is a short-interval contract on the price of Ether (ETH) for the window titled "Ethereum Up or Down - October 31, 10:40AM-10:45AM ET". The contract is listed on Polymarket and is categorized as Crypto. The saved provider record describes it as active, with a listed end time of 2026-10-31T14:45:00.000Z [1]. The contract's rule is that it resolves to "Up" if the time-weighted average price (TWAP) of Ethereum 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 outcome therefore depends on how the averaged price over the window compares with the starting price, not on where the price ends the window. The resolution source is Chainlink's ETH/USD TWAP data stream [1]. The rules state that the market concerns the price according to that Chainlink data stream, and not any other source or spot market [1]. A move on a different exchange or data feed would not, under these rules, determine the result on its own. The saved record shows one market in this event, with an "Up" outcome and a "Down" outcome [1]. The listed end time is a rule-based closing time for trading in the contract. It is not a separate announcement of a future event.

Why It Matters

The contract measures whether the Chainlink ETH/USD TWAP over a specific five-minute window, from 10:40 to 10:45 AM ET on October 31, is at or above the price at the start of that window [1]. Because the comparison uses an average over the window, the contract tests the averaged price against the opening price, not a single closing print. Because the contract names one data stream, its result is defined by that stream's values rather than by general market reporting [1].

Snapshot context

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.
