Snapshot observed 2026-10-29T18:00:06.063Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

This snapshot covers a single Polymarket contract, "Ethereum Up or Down - October 29, 11:00PM-11:05PM 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 resolution source is the ETH/USD TWAP data stream named in the rules, and the market is explicitly "not according to any other sources or spot markets" [1].

Readers should separate the time points involved. The provider observed the market at 2026-10-29T18:00:06Z, and our source retrieval occurred at 2026-10-30T00:40:53Z [1]. The listed end time is 2026-10-30T03:05:00Z [1]. The title uses Eastern Time, so the listed close corresponds to the 11:05 PM ET end written in the title. The end time is a contract closing time, not evidence of how the market finally resolved, and the supplied evidence does not record a resolution.

Reading the snapshot

The saved prices are Up at 0.505 and Down at 0.495 [1]. These are snapshot values from the observation time, not executable quotes, and they are not verified probabilities. The gap between them is small, and the evidence does not explain it. Because this is one contract, there is no other platform or event to compare against, so this snapshot should not be read as an arbitrage signal or as a cross-platform consensus.

Coverage is complete for this saved event. The record lists one total market and one included market, with no partial sample [1]. Even so, the sample warning notes that including all saved markets "does not establish that the providers list every possible real-world outcome" [1]. Here the outcomes are the two binary sides of the contract, so the Up and Down prices are the full saved field for this event.

Volume is not included in the snapshot, so nothing here reflects liquidity or the number of traders.

What remains uncertain

The evidence reports the status as "active" at the observation time [1]. It does not establish whether the contract is still open at the time you read this, since the retrieval date is now past the observation time. Prices may have changed since the snapshot was taken. The supplied material also does not include the ETH price at the start of the window, the TWAP value during it, or any reason the prices sit near even odds. Those gaps mean this snapshot can describe the contract's rules and the prices recorded at one moment, but it cannot predict the outcome or explain how the market reached these levels.
