What the contract measures

This Polymarket contract is titled "Bitcoin Up or Down - October 20, 4:30AM-4:35AM ET" [1]. Its rules state that it "will resolve 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 say 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]. Contracts with different wording or sources should not be treated as measuring the same thing.

The listed end time is 2026-10-20T08:35:00.000Z, and the provider status is active [1]. The listed end time, the observation time, and the actual resolution are separate events. The supplied evidence does not show a resolution outcome.

Reading the snapshot

The saved snapshot was observed at 2026-10-19T09:00:05.974Z and retrieved at 2026-10-19T10:00:11.729Z [1]. It records prices at that earlier moment and is not a live quote. The saved prices are Up at 0.505 and Down at 0.495 [1]. These sum to 1.000. They are snapshot prices, not executable quotes or verified probabilities. The 0.010 gap between the two outcomes is small, but the evidence does not explain it or show whether it persisted.

The sample contains one market from one platform. Coverage reports 1 total market, 1 included, and no partial sample [1]. The source notes that all saved markets for this event are included, but "This does not establish that the providers list every possible real-world outcome" [1]. Because this is a single binary contract, there is no other contract to compare it with. The supplied record also contains no volume data, so nothing can be said about liquidity or the number of traders.

What remains uncertain

The evidence does not explain why prices are where they are, whether they have changed since retrieval, or what the TWAP will show relative to the starting price. Anyone relying on these figures should check the live listing and its rules directly.
