Bitcoin price on August 13?

Platform comparison

Market context

Bitcoin's spot price at noon ET on 13 August 2026 will determine this market's outcome, with settlement tied to the precise closing price of the BTC/USDT pair on Binance's 1-minute candles. The 0% crowd probability reflects the market's current inability to price a specific price point two years forward with meaningful conviction. On Polymarket, this contract settles via USDC on Polygon, with conditional tokens representing discrete price brackets that collapse to a single winner at the settlement window's close.

Historical precedent suggests that single-day, single-hour Bitcoin price predictions more than eighteen months out carry structural uncertainty that resists confident pricing. Comparable markets tracking BTC spot prices at fixed future dates have typically seen probability mass cluster around round numbers or technical levels rather than distribute evenly across brackets. The current 0% reading indicates traders view the specificity of this market—a particular hour on a particular date in 2026—as too distant and volatile to anchor meaningful positions, a pattern consistent with how prediction markets handle long-dated, granular asset price contracts.

Catalysts shaping Bitcoin's trajectory through mid-2026 remain diffuse but material. Federal Reserve policy, institutional adoption trends, and regulatory developments in major markets will influence volatility regimes. Recent reporting from Bloomberg and Reuters on spot Bitcoin ETF flows and mining difficulty adjustments suggests the asset class continues fragmenting between macro hedge narratives and speculative trading. Traders monitoring this contract should track macroeconomic calendars, central bank communications, and any significant shifts in on-chain transaction volumes or exchange reserve levels, all of which historically correlate with directional moves in spot price.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

UK Frequently Asked Questions

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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%.
