What price will Bitcoin hit on July 31?

Platform comparison

Market context

Bitcoin’s price at the settlement time is what will decide this market, so the key question is whether BTC can hold or break into the band implied by the current listings rather than where it trades intraday. On Polymarket, the live book shows the biggest cluster around **$64,000–$66,000** at 27% and **$62,000–$64,000** at 26%, which is materially different from a Kalshi-style yes/no framing because the platform publishes a probability for each range rather than a single price threshold.[8] By contrast, a user comparing books with Betfair or Smarkets will usually need to translate decimal odds back into implied probability, then adjust for commission, whereas prediction markets often quote the probability more directly and may still differ in access and KYC requirements by jurisdiction.

Historical and comparable forecasts do not strongly support the current **0% YES** reading if that means the market is pricing an extreme outcome or an out-of-band strike. Recent July 2026 forecasts from several crypto models mostly sat in the low-to-mid **$60,000s**, with one Finbold-derived projection at **$60,013** and another at **$62,590**, while other outlets sketched a broader range from the high **$50,000s** to the low **$70,000s**.[1][2][7][9] That framing matters on a platform-comparison basis: in a range market, the same underlying view can look meaningfully different on Polymarket, Kalshi, or Betfair depending on how the contract is bucketed, whether fees are embedded in price, and whether the trader can access the venue without full exchange onboarding.

The main catalysts are macro and liquidity, especially US policy headlines, ETF flow changes, and any sharp move in risk assets before the settlement window closes at 04:00 UTC. Yahoo Finance’s July coverage pointed to a possible trading band around **$56,000–$62,000** before the Fed meeting, with resistance near **$63,800** and downside opening below **$56,200**.[7] For traders comparing platforms, that kind of range sensitivity can matter more on Kalshi, where the contract structure and legal access are often simpler to read in implied-probability terms, while Betfair or Smarkets may show the same view through odds and fees rather than a plain percentage.

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.
