Bitcoin price on August 10?

Platform comparison

Market context

Bitcoin's spot price at noon ET on 10 August 2026 will be recorded from Binance's BTC/USDT pair using the 1-minute candle close. The market resolves YES only if the settlement price falls within a specified bracket; otherwise it resolves NO. The 0% implied probability reflects either extreme confidence in a particular outcome or sparse liquidity at the current moment. Polymarket's decimal odds format and Kalshi's binary structure handle such edge cases differently—Polymarket traders typically see tighter spreads on volatile pairs, whilst Kalshi's regulated US framework may attract different order flow patterns for longer-dated crypto contracts.

Historical Bitcoin price movements over comparable 18–24 month horizons show annualised volatility ranging from 60% to 120%, making precise noon-hour predictions inherently difficult. The 2024–2025 period saw Bitcoin oscillate between $16,500 and $73,000, suggesting that any single-hour settlement window carries meaningful execution risk. Smarkets and Betfair have historically offered deeper liquidity on crypto outcomes with wider time horizons, though their fee structures (typically 2–5% commission) compress margins on tight probability bands.

Traders should monitor macroeconomic calendar events in the weeks preceding August 2026—Federal Reserve policy announcements, inflation data, and geopolitical developments typically drive Bitcoin intraday volatility. Regulatory clarity on US spot Bitcoin ETF treatment and any major exchange outages on Binance would also shift implied probabilities. The resolution mechanism's reliance on a single 1-minute candle introduces slippage risk absent from daily-close markets, a distinction worth weighing against the liquidity depth available on each platform.

Methodology

We read Bitcoin price on August 10? 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.
