Bitcoin price on August 20?

Platform comparison

Market context

Bitcoin's noon ET price on 20 August 2026 will be determined by the closing value of the BTC/USDT 1-minute candle on Binance at that precise moment. The market currently shows 0% implied probability, suggesting traders expect the contract to resolve to "No"—meaning either Binance data becomes unavailable or the price falls outside all specified brackets. On Polymarket, this contract trades as a conditional token pair on Polygon, with USDC collateral backing positions. The 0% reading reflects extreme uncertainty about whether any YES bracket will capture the actual price, or signals minimal liquidity and participation in this particular settlement window.

Historical Bitcoin price movements over comparable two-year horizons show volatility ranging from 30% to 300% annually, making long-dated price brackets inherently difficult to price with confidence. The 2024–2026 period has seen Bitcoin navigate regulatory shifts, institutional adoption milestones, and macroeconomic policy changes that compressed or expanded trading ranges unpredictably. Traders typically discount such distant contracts heavily unless specific catalysts emerge—the current 0% probability reflects this structural discount rather than conviction that Bitcoin will be unavailable or unmeasurable in August 2026.

Catalysts shaping this market include Federal Reserve policy announcements, spot Bitcoin ETF flows, and any major regulatory developments affecting US crypto exchanges. Binance's operational status in US jurisdictions remains contested; changes to its trading infrastructure could affect data availability. Halving events, scheduled for April 2028, fall outside this window but market participants often price forward-looking scarcity expectations. Traders monitoring this contract should track Binance's compliance posture and broader macroeconomic forecasts that typically drive Bitcoin's medium-term directional bias.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

UK Frequently Asked Questions

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

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?
