What price will Bitcoin hit on August 21?

Platform comparison

Market context

Bitcoin's price action on 21 August 2026 will depend on macroeconomic conditions, regulatory developments, and spot-market liquidity across major exchanges at that specific date. The 13% implied probability currently priced into this contract suggests the crowd views a particular price threshold as unlikely within the settlement window, though the exact target price remains unspecified in available market documentation.

Historical volatility patterns show Bitcoin has experienced single-day swings exceeding 10% during periods of regulatory uncertainty or Federal Reserve announcements. The August 2021 rally to $49,000 and subsequent corrections provide context: major price moves typically cluster around FOMC meetings, inflation data releases, or significant custody announcements from institutional players. Current market pricing at 13% YES implies traders expect either sideways consolidation or downward pressure through mid-August 2026, contrasting with periods when similar one-day targets carried 25–35% implied probability during bull-market phases.

Key catalysts through the settlement window include any unexpected monetary policy shifts, spot Bitcoin ETF flows (which have materially influenced price discovery since 2024), and geopolitical events affecting risk appetite. Traders should monitor July 2026 inflation data and any statements from major central banks in early August. Divergence between prediction-market pricing and options-market implied volatility will signal whether consensus has shifted; currently, the 13% figure suggests limited conviction in a sharp directional move on that specific date, with most positioning concentrated in tighter price bands.

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
