What the contract measures

This Polymarket event asks whether Ethereum will go up or down over a fixed 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, and the rules state 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]

The listed end time is 2026-10-19T22:30:00.000Z [1]. The title uses Eastern Time, so readers should compare the window in the title with this UTC timestamp rather than assume they match. The listed end time is a contract closing time, not a record of when resolution occurred.

Reading the snapshot

The saved market shows "Up" at 0.505 and "Down" at 0.495 [1]. These prices come from a snapshot observed at 2026-10-19T00:00:05.826Z and retrieved at 2026-10-19T01:31:55.059Z [1]. They describe the saved observation only and are not a current quote. They are not executable prices, and they are not verified probabilities. Because the two prices sum to 1.00 in this snapshot, the difference between them is small, but a reader should not treat that gap as a forecast of direction.

The event contains one market, and the coverage record shows one included market out of one total with no partial sample [1]. The sample therefore covers every saved outcome for this event. The record does not show any other platform, so no cross-platform comparison is possible here. Volume is not reported in this snapshot, so this record says nothing about liquidity or how many traders took part.

What remains uncertain

The evidence does not explain why the prices sit where they do, and it contains no news or market commentary about Ethereum. It also does not show the price at the start of the window or any later price, so the outcome cannot be determined from this record. The provider status is listed as active [1], but this does not confirm the market's state at the time you read this page.

If you compare this contract with a differently worded Ethereum market on another platform, check the resolution source, the TWAP definition, and the closing time first. Differences in those terms mean the prices refer to different outcomes and should not be combined or treated as an arbitrage opportunity.
