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 market is titled "Ethereum Up or Down - October 26, 10:45AM-10:50AM ET" and is listed on Polymarket [1]. The rules state that 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 resolves to "Down" [1]. The resolution source is the ETH/USD TWAP data stream named in the rules, and the excerpt says the market is "not according to any other sources or spot markets" [1]. The listed end time is 2026-10-26T14:50:00.000Z [1]. This is the scheduled close recorded in the evidence. It is not a confirmed resolution, and the supplied evidence does not show a final outcome.
Reading the snapshot
The provider observation time is 2026-10-25T15:00:05.906Z, and the source was retrieved at 2026-10-25T16:38:08.181Z [1]. The prices below describe the observation time, not the retrieval time or any later moment. The quoted prices were Up at 0.505 and Down at 0.495 [1]. These two prices sum to 1.000 in this snapshot. They are not executable quotes or verified probabilities.
The sample covers one market from one provider event. The coverage record reports 1 total market, 1 included market, and no partial sample [1]. Because only one contract is included, this snapshot offers no comparison with other markets or platforms. The provider lists the status as active at retrieval [1]. The evidence does not include volume, so it cannot be used to judge liquidity or the number of traders.
What remains uncertain
The evidence does not explain why the prices were at these levels. It also does not show what Ethereum's price did during the contract window or after the snapshot. Because the observation was taken before the retrieval time and well before the listed end time, the prices here should not be read as current.
If a reader compares this contract with a contract on another platform, differences in wording, reference source, or close time matter. Two contracts with different rules are not directly comparable, and a price difference between them is not, by itself, an arbitrage opportunity.

Saved Oct 25, 2026 UTCOverview
This is a short-term Ethereum price contract listed on Polymarket. Its title, "Ethereum Up or Down - October 26, 10:45AM-10:50AM ET", describes a five-minute window [1]. The contract resolves to "Up" if the time-weighted average price (TWAP) of Ethereum over that window is greater than or equal to the price at the start of the window. Otherwise it resolves to "Down" [1]. The contract does not use an arbitrary market price. The stated resolution source is the ETH/USD TWAP data stream published by Chainlink, which the rules identify at a specific data stream address [1]. The rules say the market concerns the price in that Chainlink stream only, and not any other data source or spot market [1]. A trader reading the contract should therefore focus on the Chainlink measurement rather than prices on individual exchanges. The listed end time is 2026-10-26T14:50:00.000Z [1]. That date is the contract's closing time under its rules. It is not evidence that a result has been announced or that the contract has settled. The provider status recorded in the retrieved source is "active" [1]. The market data attached to this article reflects a snapshot taken at the observation time shown in the dated status note, and it should not be read as a live or current quote.
Why It Matters
The contract measures whether the Chainlink ETH/USD time-weighted average price over the stated five-minute window ends at or above the price at the start of that window [1]. Because the measurement is an average over the window rather than a single moment, the outcome depends on the path of the price during the period, as well as its starting and ending levels. The rules are specific about the data source, so the contract's outcome is tied to that feed rather than to general market sentiment about Ethereum. For readers, the most useful points are the exact resolution mechanism and the closing time. The price shown for either outcome is a market snapshot. It is not an executable quote, and it is not a verified probability that Ethereum will rise. Trading volume on a contract also does not indicate how many participants are active or how easily positions can be entered or exited.
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-25 at 15:00 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 determines whether this contract resolves to Up?
It resolves to Up if the time-weighted average price of Ethereum, generated by Chainlink, across the time range in the title is greater than or equal to the price at the beginning of that range [1].
Which price feed is used for resolution?
The stated resolution source is the ETH/USD TWAP data stream from Chainlink [1]. The rules say the contract is about that Chainlink price and not about other sources or spot markets [1].
Do prices on other exchanges affect the outcome?
According to the contract rules, the market is about the Chainlink data stream and not any other sources or spot markets [1]. Prices elsewhere do not determine the result under these rules.
When does the contract close?
The listed end time in the retrieved source is 2026-10-26T14:50:00.000Z [1]. This is the closing time in the contract rules, not a record that the result has been determined.
