Market context
Bitcoin's price action on 12 August 2026 will be determined by spot and futures markets across regulated exchanges and over-the-counter desks. The contract settles based on the highest price Bitcoin reaches during that calendar day, with the settlement window closing the following morning at 04:00 UTC. The 0% crowd-implied probability across prediction markets suggests traders currently assess the likelihood of Bitcoin hitting the specified price level as negligible, though the exact threshold remains unspecified in this framing.
Historical volatility in Bitcoin's daily ranges provides context for evaluating this probability. During 2024–2025, Bitcoin experienced intraday swings of 5–12% on routine trading days, with larger moves tied to Federal Reserve announcements or macroeconomic data releases. August typically sees lighter trading volumes in traditional markets, which can amplify cryptocurrency price movements. The 2021 and 2017 bull cycles both saw Bitcoin establish new all-time highs in summer months, though such extremes remain statistically rare events. Current market structure—with Bitcoin trading across Coinbase, Kraken, Binance, and CME futures—means price discovery is near-instantaneous, reducing the likelihood of isolated spikes on any single venue.
Traders monitoring this contract should track Federal Reserve communications and inflation data scheduled for release in early August 2026, as these typically drive risk-asset repricing. Spot-market liquidity conditions and open interest in Bitcoin futures will influence intraday volatility. Divergence between prediction-market odds and analyst price targets, if any emerge closer to the settlement date, may signal information asymmetry worth investigating. Sportsbook-style crypto derivatives on platforms like Deribit offer comparable daily price-range contracts that can serve as cross-venue calibration points.
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 Kalshi vs Polymarket, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
