Bitcoin Up or Down - July 20, 7AM ET

Platform comparison

Market context

The market resolves based on whether Binance’s BTC/USDT 1-hour candle closes higher than or equal to its open price at 7AM ET on 20 July. With a current crowd-implied probability of 100% YES, the crowd expects the close to exceed the open, implying a bullish intraday move within that specific candle window.

Historically, 100% implied probabilities on short-term crypto candles often signal either extreme consensus or a data lag, as 1-hour BTC candles frequently oscillate without clear directional bias. Comparable cases from mid-2025 show that even during strong uptrends, single 1-hour candles can close flat or down due to micro-liquidity shifts. A 100% probability here is unusual for a 1-hour timeframe and may reflect delayed settlement data or a technical anomaly rather than genuine market certainty.

Traders should monitor the US session open, scheduled Fed commentary, and any Binance-specific liquidity events that could trigger volatility around the 7AM ET mark. Recent analysis notes Bitcoin consolidating near $112,200 with resistance at $112,930 and support at $109,800, suggesting limited upside momentum unless volume confirms a breakout [1]. Programmatically, this market would be approached by querying Binance’s 1H candle data via API, comparing the open and close fields, and executing conditional orders only if the close ≥ open condition is met post-finalisation.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
