Bitcoin above … on August 10?

Platform comparison

Market context

Bitcoin is being priced for a **100% YES** result, which leaves almost no room for a contrarian edge unless the noon ET Binance candle lands below the strike. With the market already assuming a near-certain win for the favourite, the cleaner handicapper’s note is that the upside is exhausted and the only real value on the board sits with an underdog view that the spot price can still slip on a short, exchange-specific print.

Comparable August forecasts are mixed but mostly sit in a broad band rather than a straight-line surge. CoinCodex has BTC around **$67,648** for 10 August, Changelly points to **$69,722.38**, and LongForecast shows a month-end close near **$65,068** with an August range from **$58,876 to $71,788**[3][1][17]. By contrast, CoinGecko’s prediction page says the highest-probability upside target for August is only **$67,500** with a **59.5%** chance, while overall sentiment is bearish[8]. That split matters here: if the title’s strike is below the high-$60ks, the consensus makes the favourite look solid, but if it is set closer to the current trading band, the market may already be fully efficient.

For catalysts, traders will watch macro prints and any ETF-flow headlines, because several August outlooks tie BTC’s direction to post-Fed positioning, inflation data, and risk sentiment[9][10][2]. One recent Yahoo Finance piece argued that August starts with a bearish technical setup and a seasonal weakness bias, with resistance only reclaimed on a move back above **$82,931**[2]. That leaves the near-term path dependent on whether fresh liquidity or a risk-off shock hits before the settlement candle, especially because a single Binance 1-minute close is vulnerable to brief exchange-specific volatility.

Methodology

We track Bitcoin above … on August 10? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
