Market context
Bitcoin's price movement will be assessed over a five-minute window on 25 May 2026, from 1:05 PM to 1:10 PM ET, using Chainlink's BTC/USD data feed as the sole resolution source. The market requires the closing price at 1:10 PM to match or exceed the opening price at 1:05 PM for an "Up" resolution; any decline triggers "Down".
Five-minute price windows in cryptocurrency markets typically exhibit high volatility, with intraday swings of 0.5–2% commonplace during standard trading hours. Historical precedent suggests that ultra-short timeframes of this duration rarely favour directional conviction; the 0% probability currently assigned reflects the inherent difficulty in predicting such granular price action. Comparable micro-window Bitcoin markets have historically resolved evenly between up and down outcomes, as five-minute candles are heavily influenced by order-book dynamics and algorithmic trading rather than fundamental shifts.
Traders should monitor scheduled macroeconomic releases and Federal Reserve communications in the days preceding the settlement window, as these can establish volatility regimes that persist into late May. Chainlink's BTC/USD feed aggregates prices from multiple exchanges, so any technical issues with major spot venues or the data feed itself could affect resolution accuracy. The specific time window falls during US trading hours, when Bitcoin typically experiences elevated volume and tighter spreads, though this offers no directional bias for such a compressed timeframe.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
