What price will Bitcoin hit on July 31?

Platform comparison

Market context

Bitcoin is trading around the end-of-month level that will determine which price band settles the market, and the current crowd view is effectively that the measured outcome is not in the money, with the book showing 0% YES. On Polymarket, this contract is framed as a multi-band price market with the leading range at 64,000-66,000 around 27% and 62,000-64,000 at 26%, which is more useful for reading distribution than a single yes/no line.[8]

That is a different lens from Kalshi-style or Robinhood-style pricing, where the same event is usually expressed as a direct probability on a threshold, so the same Bitcoin level can look very different once translated into implied odds and fees. Robinhood’s BTC market for 31 July 2026 at 6am EDT shows 63,300 or above at 98¢ and 62,900 or above at 97¢, illustrating how tightly the threshold markets can cluster near the current spot price when settlement is close.[7] External forecasts published in July were also split, with some models centring on the low-60,000s and others projecting the low-to-mid-70,000s, which leaves the distribution broad enough for platform pricing to diverge materially.[1][2][14]

Traders should watch the final US macro calendar, ETF flow headlines and any sharp move in spot BTC, because late-session volatility can quickly shift which band wins before the settlement window closes. Yahoo’s July view put Bitcoin in a roughly 56,000-62,000 range until the Fed meeting, with 63,800 cited as a near-term resistance level and 55,298 as a breakdown point, which helps explain why near-expiry markets can reprice abruptly if those levels give way.[6] KYC reach also matters: Polymarket generally speaks to a crypto-native audience, while Kalshi and broker-style books tend to be more accessible to fiat users but can use different fee and odds conventions, so the same trade can look cheaper or more restrictive depending on where it is listed.

Methodology

We read What price will Bitcoin hit on July 31? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

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.
