Market context
This market tracks whether Bitcoin's price will be higher or equal at 9:00PM ET on 13 July compared to 8:55PM ET the same evening, using Chainlink's BTC/USD oracle feed as the settlement source. A YES share pays out if the price rises or stays flat over that five-minute window; a NO share pays out if it falls. The current crowd probability of 100% YES reflects an expectation that Bitcoin will not decline during this specific five-minute interval.
Five-minute price movements in Bitcoin are inherently difficult to predict with certainty, yet the market shows complete confidence in an upward or neutral outcome. Historical precedent suggests such extreme probabilities in ultra-short-term markets often reflect either genuine directional momentum or the illiquidity of small-stake prediction markets where few traders have positioned themselves. Bitcoin's intraday volatility typically ranges between 0.5–2% across hourly periods, meaning a five-minute window could plausibly move either direction, though the absence of any NO positions suggests traders view downside risk as negligible during this particular timeframe.
The settlement depends entirely on Chainlink's BTC/USD data stream, which aggregates prices from multiple exchanges rather than reflecting any single spot market. Traders should note that flash crashes, exchange-specific price deviations, or temporary data feed anomalies could theoretically affect settlement, though Chainlink's architecture is designed to filter extreme outliers. No scheduled announcements or macroeconomic releases are tied to this specific five-minute window, meaning price movement would likely reflect organic market flow or algorithmic trading activity rather than news-driven catalysts.
Methodology
This page reviews Bitcoin Up or Down - July 13, 8:55PM-9:00PM ET across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to Prediction Market UK, which mirrors the Polymarket order book at 0% fees.
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.
