Snapshot observed 2026-10-26T06:00:06.440Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

This is a single Polymarket contract titled "Bitcoin Up or Down - October 26, 9:00PM-9:15PM ET" [1]. It resolves to "Up" if "the time-weighted average price (TWAP) of Bitcoin, 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 Chainlink BTC/USD TWAP data stream, and the rules state that the market concerns "the price according to the TWAP Chainlink data stream for the asset pair BTC/USD, not according to any other sources or spot markets." [1] A reader comparing this with a Bitcoin price quoted elsewhere should expect differences in source and averaging method. The listed end time is 2026-10-27T01:15:00.000Z [1], which is the close of the 9:15 PM ET window named in the title. Listed close time is not the same as the actual resolution, which the supplied evidence does not show.

Reading the snapshot

The provider observed the market at 2026-10-26T06:00:06.440Z, and this material was retrieved at 2026-10-26T06:42:07.377Z [1]. The prices below describe that observation window, not live trading conditions at the time of reading:

• Up: 0.505
• Down: 0.495

These are the only two outcomes saved for this event, and the sample covers the whole saved event: one market, all included, with no partial sample [1]. Because the two prices sum to 1.000, they read as complementary within this snapshot. The Up price sits slightly above the Down price, but a gap of 0.01 is small, and the evidence does not explain it.

These figures are snapshots, not executable quotes or verified probabilities. The supplied evidence includes no bid, ask, depth, or volume figures, so it says nothing about liquidity or how many traders are involved.

What remains uncertain

The evidence does not show prices after the observation time, the outcome of the 9:00 PM to 9:15 PM ET window, or the result of the contract. It also does not show why the prices stand where they do. A reader should not treat this single snapshot as a forecast of Bitcoin's direction, and the evidence offers no basis for comparing its accuracy with other forecasts.

Because only this contract is supplied, no comparison with other platforms or Bitcoin contracts is possible here. Contracts with different wording, sources, or close times should not be treated as an arbitrage opportunity merely because their prices differ.
