What the contract measures

This Polymarket contract asks whether Bitcoin will go up or down during a 15-minute window. The contract states 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" [1]. Otherwise it resolves to "Down" [1].

The resolution source is the Chainlink BTC/USD TWAP data stream, and the contract says it is "about 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 contract on another platform should check whether that contract uses the same data source, time window, and comparison rule, because differences in wording can change what each price means.

The listed end time is 2026-10-30T12:30:00.000Z [1]. The title's 8:15AM to 8:30AM ET window corresponds to that closing time, but the listed end time is the close time, not a report of the outcome.

Reading the snapshot

The saved snapshot was observed at 2026-10-30T09:00:06.125Z and retrieved at 2026-10-30T10:32:35.039Z. It shows Up at 0.505 and Down at 0.495 [1]. These are snapshot prices from the observation time, not current quotes, and they are not executable prices or verified probabilities. The gap between observation and retrieval means the figures should not be read as reflecting conditions at the time of retrieval.

The sample covers one market in one saved provider event, with all saved markets included and no partial sample flagged [1]. Because the sample is complete for this event, the two prices are the full set saved for this contract. The data does not show why the prices were where they were, and trading volume is not reported here, so the snapshot cannot indicate liquidity or how many people traded.

What remains uncertain

The evidence does not include the Bitcoin price at the start of the window, the TWAP during the window, or the final result. It also does not establish whether the market has resolved, and the provider status at retrieval was recorded only as "active" [1]. The snapshot therefore cannot say which outcome occurred.

Any comparison with another platform should keep the contracts separate unless their rules match. Price differences between contracts with different rules are not evidence of an arbitrage opportunity.
