Snapshot observed 2026-10-27T06:00:05.981Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

This snapshot covers one Polymarket event, "Ethereum Up or Down - October 28, 12:40AM-12:45AM ET" [1]. The provider 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 provider 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 comparing this with another ether price contract should check whether that contract uses the same data stream, averaging method, and time window.

The listed end time is 2026-10-28T04:45:00.000Z, which is the close recorded for this contract [1]. The title's ET window is the contract's stated period. The end time is a listed contract close, not an announced event or a confirmed resolution.

Reading the snapshot

The observed prices were Up at 0.505 and Down at 0.495 [1]. These are snapshot values, not executable quotes, and they are not verified probabilities. The two prices sum to 1.00 in this record, which is consistent with a two-outcome contract, but the snapshot does not show spreads, depth, or whether either side could be filled at these levels.

The observation time was 2026-10-27T06:00:05.981Z, and the source was retrieved at 2026-10-27T06:27:48.889Z [1]. The status was active at the time of retrieval. Because this is a recorded observation, it should not be read as the price at the moment you read this text. Later prices may differ.

The Up price is slightly higher than the Down price in this snapshot. That gap is small, and the record does not explain it or indicate what drove it.

What remains uncertain

This sample includes one market from one event. The coverage record shows one total market and one included market, with no partial sample [1]. The sample therefore describes only this contract, not the full range of crypto contracts or other platforms.

The record does not include volume, liquidity, or the number of traders, so it cannot show how deep the market is or how many participants hold each side. It also does not show whether any other platform lists a similar contract with the same resolution rules. Prices from different contracts should not be treated as comparable, and a price difference between them is not evidence of an arbitrage opportunity without matching terms.

Final resolution depends on the TWAP comparison described in the rules and has not occurred in this record.
