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 on the Ethereum price over a five-minute window. The source says 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 resolution source is the ETH/USD TWAP data stream from Chainlink, and the source states 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 should not assume that this contract tracks other ETH exchange prices or any other Ethereum benchmark.

The listed end time is 2026-10-31T02:30:00.000Z. [1] The window in the title is labeled 10:25PM-10:30PM ET. The contract rules state the end time in UTC, so readers comparing the two should convert time zones carefully.

Reading the snapshot

The saved snapshot was observed at 2026-10-30T21:00:05.889Z and retrieved at 2026-10-31T00:01:56.298Z. [1] These are different timestamps, and the prices describe the observation time, not the retrieval time or any later moment.

At observation, the saved prices were 0.505 for "Up" and 0.495 for "Down." [1] These are snapshot prices, not executable quotes, and they are not verified probabilities. The source status at retrieval was "active," but that describes the saved record, not whether the market is still trading now.

This sample contains one market from one provider event, and the source marks it as complete for that event. [1] Because there is only one contract, there is no comparison with other platforms or other Ethereum windows in this evidence. The saved record does not include trading volume or trader counts, so this snapshot cannot indicate liquidity or how many participants hold a view.

What remains uncertain

The evidence does not show why the prices were 0.505 and 0.495 at the observation time, and it contains no reporting that explains any price movement. The saved record also does not show the Ethereum price at the start of the window or the TWAP during the window, so the eventual outcome cannot be determined from this material. A later retrieval would be needed to confirm the final resolution.

Overview

This is a short-window crypto contract on Ethereum's price, listed on Polymarket under the title "Ethereum Up or Down - October 30, 10:25PM-10:30PM ET" [1]. The contract covers a five-minute window from 10:25 PM to 10:30 PM Eastern Time on October 30. Its outcomes are "Up" and "Down" [1]. The rules state that the market resolves to "Up" if the time-weighted average price (TWAP) of Ethereum over the window is greater than or equal to the price at the beginning of that window. Otherwise it resolves to "Down" [1]. The price used is generated by Chainlink, and the rules name its ETH/USD TWAP data stream as the resolution source [1]. The rules also say the market concerns that Chainlink data stream only, not other sources or spot markets [1]. The saved snapshot was observed at 21:00 UTC on October 30, 2026, and showed "Up" at 0.505 and "Down" at 0.495 [1]. These are snapshot prices from that moment. They are not current prices, executable quotes, or verified probabilities. The listed end time is 02:30 UTC on October 31, 2026, which is 10:30 PM Eastern Time on October 30 [1]. The evidence does not include a resolved outcome for this contract.

Why It Matters

The contract measures whether the Chainlink ETH/USD time-weighted average price over the five-minute window is at or above the price at the start of that window [1]. Because the outcome depends on a time-weighted average rather than a single spot price at the close, the result reflects the average behavior of the reference feed across the window, as defined by the rules [1]. Readers should keep in mind that the contract's price reflects trading in this market on this platform at the snapshot time, not a forecast verified by the evidence [1].

Snapshot context

The latest published provider snapshot for this topic was observed on 2026-10-30 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. [1]

Frequently Asked Questions

What price determines the result?

The rules use the time-weighted average price of Ethereum generated by Chainlink, specifically its ETH/USD TWAP data stream, over the time range in the title [1].

What counts as "Up"?

The market resolves to "Up" if the TWAP over the window is greater than or equal to the price at the beginning of that window [1].

Do other exchanges or spot markets affect the outcome?

The rules say the market is about the Chainlink TWAP data stream for ETH/USD and not other sources or spot markets [1].

Do the snapshot prices show the current odds?

No. The prices were observed at 21:00 UTC on October 30, 2026, and they are snapshots rather than current quotes or verified probabilities [1].
