Bitcoin price on August 8?

Platform comparison

Market context

Bitcoin’s noon ET Binance close for 8 August is being priced against a spot market that has spent much of August clustered in the mid-$60,000s, with recent data showing a month-end close near $64,878 and a 7 August finish at $64,878 after a 1.0% daily rise.[1] Live trackers around the same point in time put BTC near $64,573 to $64,916, which sits close to the top of the current Polymarket range and helps explain why the crowd-implied YES probability can still look detached from the broader spot level if the contract is misread as a directional bet rather than a bracket outcome.[2][4][14]

For historical framing, the main reference case is the surrounding August price band rather than any single print: Bitcoin’s recent daily closes have been sitting around $63,000 to $65,000, and one widely used historical feed puts the latest 2026 daily close at $64,608.71 on 6 August.[6][13] On Polymarket, the leading bucket is reported at 98% for 64,000–66,000, while the adjacent 62,000–64,000 band is only 1%, which shows a very different pricing language from Kalshi or Betfair-style books, where traders more often read decimal odds or direct implied probability off the screen rather than bucketed ranges.[14]

The immediate catalysts are the U.S. macro calendar and any crypto-specific flow that can move BTC within a single afternoon candle, because the settlement uses Binance’s 1-minute 12:00 ET close rather than a daily average.[16] That makes the market sensitive to late-session volatility, spot ETF flow headlines, and any abrupt moves in broader risk assets, while platform mechanics matter too: Polymarket’s range market can trade with low displayed yes/no probabilities across adjacent bins, whereas fee treatment, KYC access, and liquidity depth differ across Kalshi, Betfair and Smarkets, which can leave the same BTC level priced quite differently across venues.
