Bitcoin price on August 8?

Platform comparison

Market context

Bitcoin is trading in the mid-$64,000s, while the market in question settles on Binance’s 12:00 ET BTC/USDT one-minute candle close for the date named in the contract. That means a spot price around $64.9k, as shown by recent market feeds, sits well below the Polymarket framing and also below most third-party daily forecasts, making the current 0% YES crowd price look like a view that the contract’s settlement print will land outside the targeted range rather than a simple directional bet on Bitcoin itself.[2][13][15]

Comparable readings from this week show Bitcoin mostly oscillating around the mid-$64k area: StatMuse put the 8/8 trade-day close at $64,929.01, CoinDesk showed $64,846.41, and YCharts logged $64,608.71 for 6 August. That cluster is useful because it suggests the contract is being priced against a fairly tight band of intraday outcomes, with Robinhood’s range market concentrating interest around $64,500–$65,249, which is noticeably closer to current spot than Polymarket’s leading bucket in its separate event. By contrast, analyst-style forecasts from Changelly and MEXC sit a little above current levels, which supports some upside bias but not a decisive move into the highest brackets.[2][11][13][14][15][20]

For traders, the main catalysts are the usual intraday Bitcoin drivers rather than any single scheduled event: ETF flow headlines, macro data that shifts US rate expectations, and the dollar’s direction. Recent commentary has linked August’s firmness to institutional inflows, whale accumulation, and softer rate-hike expectations, while support has been identified around $62.9k–$63.0k and resistance near $64.5k–$65.0k. Against that backdrop, the key question is whether the noon ET Binance candle captures a brief breakout above the recent congestion or simply prints another close inside the same narrow range.[6][13]

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.
