Bitcoin above … on August 13?

Platform comparison

Market context

This market resolves based on Bitcoin's closing price on the Binance BTC/USDT spot pair at the 12:00 noon ET candle on 13 August 2026. The settlement hinges on a single one-minute candle's close, making it sensitive to intraday volatility and order-book depth at that precise moment rather than broader directional conviction. Binance's spot market typically exhibits tighter spreads than perpetual futures, though noon ET often coincides with elevated US market activity and can see material volume swings tied to equity index moves or macroeconomic data releases.

The 100% implied probability suggests the threshold price is set substantially below current spot levels or consensus expectations for that date. Historical precedent shows that single-candle resolution markets at major exchanges rarely fail to settle when the underlying asset remains tradeable; Binance's infrastructure has proven reliable for such granular data capture. However, extreme flash crashes or exchange outages—though rare—have occasionally created settlement disputes in crypto markets. Traders should verify the exact price threshold specified in the market title, as even modest thresholds can carry meaningful risk if Bitcoin experiences unexpected consolidation or a sharp pullback in the weeks leading to August 2026.

Key catalysts include Federal Reserve policy announcements, Bitcoin's correlation with equity volatility, and any material shifts in on-chain whale accumulation patterns tracked by platforms such as Glassnode. Funding rates on perpetual futures can signal positioning extremes that sometimes precede intraday reversals. Any significant regulatory news affecting US spot trading or USDT liquidity could influence noon ET order flow, though such events would need to occur within hours of settlement to materially affect a single candle's close.

Methodology

This page reads Bitcoin above … on August 13? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

UK Frequently Asked Questions

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

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%.
