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 binary contract from Polymarket titled "Ethereum Up or Down - October 16, 8:50AM-8:55AM ET" [1]. The 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 will resolve to "Down"" [1]. The reference is the Chainlink 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].
Because the contract depends on a time-weighted average and a specific data stream, it should not be compared directly with a contract that uses a spot price, another exchange, or a different window. Any comparison with a differently worded market would need its own rules reviewed first.
Reading the snapshot
The saved snapshot was observed at 2026-10-15T16:13:13.851Z and retrieved at 2026-10-15T18:21:26.397Z [1]. The quoted prices were Up at 0.505 and Down at 0.495 [1]. These are snapshot values from that observation time. They are not current prices, executable quotes, or verified probabilities, and the evidence does not show what the prices are now.
The listed end time is 2026-10-16T12:55:00.000Z, and the provider status at retrieval was "active" [1]. The end time marks when the contract closes, not when it resolves. The evidence does not report a resolution outcome.
The sample covers one market from one provider event. The coverage record shows one total market, one included, and no partial sample [1]. Even so, the sample warning notes that "This does not establish that the providers list every possible real-world outcome" [1]. The evidence contains no volume figure, so nothing can be said about liquidity or trader participation.
What remains uncertain
The evidence does not explain why the quoted prices were where they were at observation. It also does not show whether the ETH price moved before or after the snapshot, or whether the prices have changed since. The 0.505 and 0.495 quotes sit close together, but this single snapshot does not establish which side the market favors in any meaningful sense.
Readers should check the provider page directly for current prices, the live status, and the eventual resolution, which the supplied evidence does not contain.

Saved Oct 15, 2026 UTCOverview
This contract is a short-window price market on Ethereum, titled "Ethereum Up or Down - October 16, 8:50AM-8:55AM ET" [1]. It is listed on Polymarket and is categorized as crypto [1]. The contract does not ask whether Ethereum will reach a particular level. It asks whether the price over a five-minute window ends up at or above where it began. The rule is specific. 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 two outcomes are therefore Up and Down, and the contract makes no reference to any other threshold or event. The resolution source is the ETH/USD TWAP data stream published by Chainlink [1]. The rules state that the market concerns only that Chainlink data stream for the ETH/USD pair, and not any other data source or spot market [1]. A reader comparing this contract with an exchange price chart should expect that difference to matter. The listed end time is 2026-10-16T12:55:00.000Z [1]. That is the time the provider lists for the contract window to close. The listed end time is not a record of how or when the contract was settled, and no settlement outcome is described in the supplied material.
Why It Matters
The contract measures a narrow, rules-defined question about the ETH/USD price. Because resolution depends on a time-weighted average from one named Chainlink data stream, the outcome reflects that feed's averaged price over the window rather than a single trade or a general market view [1]. Readers should keep the contract's wording in mind: the comparison is between the averaged price across the window and the price at the window's start, with a tie counting as Up [1].

Frequently Asked Questions
What determines whether this market resolves Up or Down?
The market resolves Up if the Chainlink time-weighted average price of Ethereum 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 price source is used for resolution?
The resolution source is the Chainlink ETH/USD TWAP data stream. The provider states that other sources or spot markets are not used for this contract [1].
Does the listed end time show when the market settled?
No. The listed end time of 2026-10-16T12:55:00.000Z is the time the provider lists for the contract window to end [1]. It does not by itself establish the settlement result.
