Market context
Bitcoin's price movement will be assessed over a five-minute window on 25 May 2026 between 1:05pm and 1:10pm Eastern Time, using Chainlink's BTC/USD data feed as the settlement source rather than spot exchange prices. The market resolves to "Up" if the closing price meets or exceeds the opening price within that interval, otherwise "Down".
Five-minute Bitcoin price intervals exhibit minimal directional bias historically. Intraday volatility clustering means that consecutive short windows often move in the same direction, yet the probability of any given five-minute candle closing higher than it opened hovers near 50% across most market conditions. The 0% crowd probability suggests either a technical glitch in market display or an extreme consensus view that warrants scrutiny, as such certainty is rarely justified in sub-ten-minute timeframes where bid-ask spreads and order flow dynamics create genuine uncertainty.
Traders should monitor macroeconomic data releases scheduled for that morning, particularly US inflation or employment figures that could trigger volatility spikes before the settlement window. Chainlink's BTC/USD feed aggregates multiple price sources, so any significant divergence between major exchanges during that five-minute period could affect settlement. Market-wide liquidity conditions and any cryptocurrency-related regulatory announcements in the preceding hours will shape volatility expectations. The specific time window falls during US morning trading hours, typically a period of moderate volume compared to European or Asian session peaks.
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
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
