Market context
Bitcoin is the asset whose end-of-day price on 31 July will determine settlement, and the current crowd-implied chance of a **YES** outcome is 0%, which makes this contract look heavily discounted relative to broader price expectations. By contrast, a recent Polymarket pricing page showed traders clustering around the **$64,000-$66,000** and **$62,000-$64,000** ranges for the same date, while Robinhood’s range market also listed the mid-$64,000 bands among the active outcomes[8][6]. That leaves a noticeable gap between this contract’s zero bid and the broader market’s view that Bitcoin remains more likely to finish in the mid-$60,000s than in the extreme tails.
Comparable July forecasts have mostly centred on a wide band rather than a single point, with machine-generated estimates spanning roughly **$53,000 to $66,500** depending on model assumptions[1][2]. Yahoo Finance’s late-July analysis also framed Bitcoin as trading between **$56,000 and $62,000** into the Federal Reserve meeting, with upside only if price reclaimed the low-$60,000s and downside reopening below support around **$56,200**[7]. That makes the analyst consensus more cautious than the range-implied prediction markets, but still far from a view that this contract should be priced as impossible.
For traders, the main catalysts are the late-month macro calendar and any move through key technical levels. The Yahoo analysis singled out the Fed meeting as a near-term dependency, with resistance around **$62,500-$63,800** and a break above **$63,800** needed to improve the bullish case[7]. Any ETF-flow headlines, regulatory announcements, or sharp spot moves in the final session would matter disproportionately because this market resolves on the closing price window rather than an intraday touch.
Methodology
We track What price will Bitcoin hit on July 31? 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
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- What does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
