Bitcoin above … on August 24?

Platform comparison

Market context

This market settles on whether Bitcoin's price at noon ET on 24 August 2026, measured via Binance's BTC/USDT 1-minute candle, closes above a specified threshold. The 99% implied probability reflects confidence that Bitcoin will trade above this level at that precise moment, though the exact price threshold determines whether this represents a near-certainty or a more meaningful wager. Resolution depends entirely on Binance's recorded close price for that single candle—not average prices, not other exchanges, not intraday highs or lows.

Historical volatility in Bitcoin's intraday movements suggests that even modest price thresholds face execution risk. During 2023–2024, Bitcoin exhibited daily swings exceeding 5–10%, though noon ET closures have rarely deviated sharply from broader daily trends. Markets pricing similar single-point-in-time Bitcoin contracts have occasionally seen last-minute reversals driven by news flow or liquidation cascades, particularly when thresholds sit near technical support or resistance levels. The settlement window's specificity—a single 1-minute candle rather than a daily close—introduces microstructure risk that broader Bitcoin price movements alone cannot fully capture.

Traders should monitor macroeconomic data releases scheduled for August 2026, including any Federal Reserve communications or employment reports that could trigger volatility in the hours before noon ET. Geopolitical developments, regulatory announcements affecting major exchanges, or significant on-chain movements can shift Bitcoin's intraday trajectory. The USDC settlement on Polygon means traders holding positions should verify their conditional token balances and liquidity conditions as the resolution date approaches, particularly given the extended timeframe to August 2026.

Methodology

This page is a comparison snapshot: one live quote, 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.
