Bitcoin above … on August 12?

Platform comparison

Market context

This market resolves based on Bitcoin's closing price on the Binance BTC/USDT pair at noon Eastern Time on 12 August 2026, using the 1-minute candle data. The settlement hinges on a single data point—the precise close of that one-minute bar—rather than daily or hourly aggregates, which introduces microstructure sensitivity to order flow and liquidity conditions at that exact moment.

The 100% implied probability reflects the market's assessment that Bitcoin will trade above the specified threshold at that particular timestamp. Historical precedent suggests such extreme confidence typically emerges when the threshold sits substantially below prevailing spot prices or when the time horizon is sufficiently distant to accommodate normal volatility. Bitcoin's intraday volatility at noon ET has historically ranged between 0.5–2% on non-announcement days, meaning the actual likelihood depends entirely on where the threshold price sits relative to current levels. Comparable single-candle resolution markets on major exchanges show that when the strike price is set far in-the-money, crowd probabilities routinely cluster at 95–100%.

Traders should monitor regulatory announcements from the US Securities and Exchange Commission or Federal Reserve communications scheduled near the resolution date, as these occasionally trigger sharp intraday moves. Binance's operational status and any scheduled maintenance windows affecting data availability warrant attention. The specific noon ET timestamp means US market hours dynamics—particularly the overlap with European afternoon trading—will influence liquidity and bid-ask spreads at that moment. Recent Bitcoin volatility clustering suggests watching for macroeconomic data releases or geopolitical events in the weeks preceding August 2026.

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

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.
