What price will Bitcoin hit on August 19?

Platform comparison

Market context

Bitcoin's price movement on a single calendar day remains one of the most volatile and difficult-to-predict outcomes in crypto markets. The settlement window closes on 20 August 2026, capturing whatever price level Bitcoin reaches during the 19 August trading window across major spot exchanges. The 0% crowd-implied probability across prediction markets suggests traders view this as either an extremely unlikely outcome or a contract with insufficient liquidity and participation to establish meaningful odds.

Historical precedent shows single-day Bitcoin price targets attract minimal trading volume compared to longer-dated quarterly or annual price forecasts. During 2021–2023, similar one-day price-level contracts on Polymarket and Kalshi rarely exceeded five-figure notional volume, with most settling on technical grounds rather than reaching the specified price. The current zero probability reflects both the inherent difficulty of timing intraday volatility and the typical pattern of prediction-market participants favouring multi-week or multi-month horizons where macro catalysts—Federal Reserve policy shifts, spot exchange-traded fund flows, or regulatory announcements—carry measurable weight.

Traders monitoring this contract should track macroeconomic calendar events in mid-August 2026, particularly any US inflation data or central bank communications that could trigger broader equity and crypto liquidations. Bitcoin's correlation with risk-on sentiment remains the primary driver of daily moves; geopolitical developments or unexpected corporate custody announcements can also shift prices sharply within hours. Cross-platform comparison shows Kalshi's regulatory framework typically attracts more institutional participation in crypto derivatives, whilst Polymarket's larger user base may eventually concentrate liquidity if the contract gains attention closer to settlement.

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.

FAQ

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.

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 PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
