Market context
Bitcoin is trading through Polymarket as a USDC-denominated contract on Polygon, with the outcome resolved by whether Bitcoin touches the specified price level at any point before settlement, so the current **0% implied yes price** means the market is pricing that hit as effectively unreachable from here. In practical terms, the contract settles via conditional tokens, so the key question for a user is not where BTC finishes August but whether price trades through the trigger at any time before the window closes.
That **0%** reading is easiest to compare with the wider August forecast spread, which is far from unanimous. Recent price-prediction coverage places August outcomes anywhere from the high-$50,000s to the low-$70,000s, with some models clustering around the low-to-mid $60,000s and others allowing a rebound towards $68,000-$70,000 if support holds[1][4][7][10]. On that basis, a zero-priced contract suggests the market believes the required strike is well outside the plausible August trading range, or that the trigger is structured around a level BTC is unlikely to touch even if the month is volatile.
A trader watching this market should focus on event risk that can force a sharp intramonth move: Federal Reserve timing, ETF flow data, and any policy headlines around the CLARITY Act or other crypto legislation are the most obvious scheduled catalysts cited in current coverage[4]. Those catalysts matter because they can create short-lived spikes that are more relevant to a “hit” contract than month-end closes, especially if BTC is already sitting near a technical support or resistance band. On Polymarket, that means watching spot moves, not just directionality, because a brief wick through the strike is enough for settlement.
Methodology
This page reviews What price will Bitcoin hit in August? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.
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.
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.
- 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.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
