Market context
Bitcoin needs to touch a specific price threshold on 6 August, so the market is really about whether the day’s high prints through that level rather than where it closes. On Robinhood’s event page, the comparable line is already shown as **$64,600 or above** at 99¢, which highlights how these markets are often priced in clear probability terms, whereas platforms such as Polymarket and Kalshi typically present similar views via different contract conventions and fee layouts; Betfair and Smarkets instead show *decimal odds*, so the same view can look more or less attractive once commission, spread and liquidity are included.[7]
Historical and forecast material points to a fairly wide August range, with several public models clustering around the low- to mid-$60,000s and some downside scenarios into the high-$50,000s. Forecasts published this month put August in the $60,000–$66,000 zone in a base case, while other outlooks allow for a move towards $68,000–$70,000 if macro data and risk appetite improve; that makes a very low crowd-implied price on an “at any time on 6 August” style market more a statement about the contract framing than a clean read on Bitcoin’s spot range.[1][6][11][16]
The main catalysts are the US macro calendar and crypto-specific flow news. Traders are watching the inflation print due on 12 August, because a cooler result could ease rate pressure, while a hot reading would tend to tighten financial conditions and weigh on non-yielding assets like Bitcoin.[6] ETF inflows, exchange liquidity and any late-session policy headlines can also matter disproportionately on a one-day threshold market, especially when settlement is tied to a narrow UTC window rather than a full trading month.[11][18]
Methodology
This page compares What price will Bitcoin hit on August 6? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. The live probability is the Polymarket mid; the comparison columns summarise each venue's fee structure, KYC, settlement currency and payment rails. Every CTA routes to Robinhood Prediction Markets, which mirrors the Polymarket order book at 0% fees.
Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
