Bitcoin price on August 5?

Platform comparison

Market context

Bitcoin will be fixed to a single Binance **1-minute BTC/USDT close** at **12:00 noon ET** on the settlement date, so the market is really about one snapshot rather than the day’s average or the spot price elsewhere. In these markets, a **YES** share pays out if the reported close lands in the specified price range; a **NO** share pays out if it does not.

The current crowd-implied price of **0% YES** says traders are treating the listed outcome as extremely unlikely, which is unusual for a live Bitcoin market and often reflects either thin liquidity or a view that the contract’s bracket is badly mismatched with where BTC is trading. Around 5:45 a.m. ET, Bitcoin was quoted near **$64,137**, with other recent price checks clustering around the mid-$64,000s, so the relevant question is whether the noon candle close ends up inside the market’s target band rather than whether Bitcoin is broadly “up” or “down” on the day.[1][4]

For traders, the main catalysts are the same forces that can move BTC quickly over a few hours: exchange-traded fund flows, macro headlines, regulatory statements, and broad risk sentiment. Recent commentary also points to Bitcoin holding in a relatively tight intraday range, with resistance above and support below, which matters because a one-minute close can flip on a brief spike or dip rather than a sustained move.[4] The timing also matters: this contract resolves on a fixed afternoon UTC cut-off, so late-session US headlines, New York market moves, or a sharp move in the hour around noon ET can be decisive even if the wider trend is calm.

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

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.

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%.
