Bitcoin above … on August 13?

Platform comparison

Market context

This market resolves based on Bitcoin's closing price on the BTC/USDT pair at Binance during the 12:00 noon ET candle on 13 August 2026. The settlement hinges on a single 1-minute candle's close value, making it a precise intraday snapshot rather than a daily close. For traders using conditional orders or algorithmic execution, the specificity matters: you're monitoring one exchange, one trading pair, and one discrete minute across a two-year window.

A 100% crowd probability at this distance suggests the market is pricing in either an extremely high strike price relative to expected Bitcoin valuations, or insufficient liquidity to reflect genuine uncertainty. Historical precedent shows that intraday Bitcoin volatility at noon ET typically ranges 1–3% on ordinary trading days, though this varies sharply around macroeconomic announcements. Comparable markets settling on single-candle closes have resolved YES when strikes were set conservatively; the crowd's confidence here warrants checking whether the unnamed strike price reflects realistic mid-range expectations for August 2026 Bitcoin levels.

Traders evaluating this through bot or copy-trading infrastructure should flag dependencies: US economic data releases, Federal Reserve communications, and any major cryptocurrency regulatory announcements scheduled near that date will influence intraday volatility. Bitcoin's correlation with equity futures during US morning hours remains a material factor. Programmatically, the resolution path is straightforward—query Binance's historical candle data at settlement time—but the predictive work lies in assessing whether current pricing reflects genuine consensus or merely sparse order flow on an extreme strike.

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

Where can I trade this market with the lowest fees?

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

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.

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%.
