What price will Bitcoin hit on August 11?

Platform comparison

Market context

Bitcoin's price trajectory on 11 August 2026 remains a two-year forecast with minimal historical precedent for such distant settlement windows across major prediction platforms. The 0% crowd probability reflects either extreme confidence in a narrow price band or genuine illiquidity in a market where most traders cluster around nearer-term expiry dates. Polymarket's AMM-based liquidity model typically shows wider spreads on long-dated crypto contracts compared to Kalshi's order-book structure, which can suppress apparent probability on low-volume tails. Betfair and Smarkets, operating under UK gambling regulation, often display higher participation in crypto price bands once they reach 18–24 month horizons, though their decimal odds format obscures the same zero-probability readings as Polymarket's implied percentages.

Historical Bitcoin price movements suggest annual volatility of 60–80% in bull markets and sharper drawdowns during bear cycles, making August 2026 forecasts highly sensitive to macroeconomic regime shifts rather than near-term technicals. The halving cycle in April 2024 and subsequent market dynamics through 2025 will shape baseline expectations; traders should monitor Federal Reserve policy, institutional adoption announcements, and spot ETF inflows as primary catalysts. Regulatory clarity in major jurisdictions—particularly US classification frameworks and EU Markets in Crypto Regulation (MiCA) enforcement—will influence whether the market reprices toward consensus by mid-2026.

The settlement window closing 12 August 2026 at 04:00 UTC creates a tight daily window; traders should verify each platform's exact price feed source and settlement methodology, as Polymarket, Kalshi, and Betfair may reference different spot indices or exchange closures.

Methodology

We read What price will Bitcoin hit on August 11? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
