Bitcoin above … on August 26?

Platform comparison

Market context

This contract settles on Bitcoin's Binance spot price at precisely noon Eastern Time on 26 August 2026, using the 1-minute candle close on BTC/USDT. The 99% crowd probability reflects confidence that Bitcoin will trade above the specified threshold at that exact moment—a narrow temporal window that eliminates most macro uncertainty and hinges instead on intraday volatility and Binance's order-book conditions during the noon ET window.

Historical precedent suggests such tight, single-candle contracts rarely resolve to "No" unless the threshold sits at an extreme outlier. Bitcoin's daily trading range typically spans 2–5% on ordinary market days, meaning a noon close would need to coincide with a flash crash or exchange-specific liquidity event to breach a reasonably set barrier. The 99% pricing reflects this mechanical reality: Binance's BTC/USDT pair trades continuously with deep liquidity, and a single 1-minute candle at noon ET is unlikely to deviate sharply from the preceding 24-hour context unless a major announcement or market shock occurs during Asian or European morning hours.

Traders should monitor scheduled cryptocurrency policy announcements, US economic data releases, and any Binance platform incidents in the weeks before settlement. Geopolitical or regulatory news breaking before noon ET on 26 August could trigger volatility, though the resolution window's brevity means only same-day shocks matter. The USDC settlement on Polygon means traders holding positions should verify their conditional token balances and redemption mechanics well before the settlement date, as post-resolution liquidity can tighten rapidly.

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

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?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
