Market context
Bitcoin's price action on a single day in August 2026 remains difficult to forecast with precision, yet the 2% implied probability across prediction markets suggests traders view a specific price target as unlikely within that 24-hour window. The settlement window closes on 21 August 2026, meaning the contract resolves based on Bitcoin's spot price during trading on 20 August—a date with no scheduled macroeconomic announcements or regulatory deadlines of note at present.
Historical volatility patterns show Bitcoin routinely moves 5–10% intraday, yet hitting a particular price point requires both directional movement and timing alignment. During 2021–2023, single-day price swings of $2,000–$5,000 occurred regularly, but the probability of landing on any one specific level within a 24-hour period remained low unless that level coincided with major support or resistance. The current 2% probability aligns with how prediction markets typically price tail-event specificity: plausible in absolute terms, but unlikely relative to the broader distribution of outcomes.
Traders monitoring this contract should track Bitcoin's macro positioning in Q2–Q3 2026, including Federal Reserve policy signals, institutional adoption announcements, and spot exchange-traded fund flows, all of which shape medium-term price direction. Cryptocurrency-specific catalysts—regulatory clarity from major jurisdictions, mining difficulty adjustments, or major exchange developments—could shift volatility expectations. Sportsbooks do not price Bitcoin daily price targets, leaving prediction markets as the primary venue for this contract; divergence between platforms remains minimal given the niche nature of the bet.
Methodology
We track What price will Bitcoin hit on August 20? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.
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.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
