Market context
The market is pricing a 1% chance that Bitcoin's price at noon ET on 4 June 2026 will be higher than its price at noon ET on 3 June 2026. This is a tight intraday directional bet settled on Binance spot prices, with resolution conditional on exact candle closes at those two timestamps. The 1% probability reflects the crowd's assessment that Bitcoin is substantially more likely to move downward or remain flat over that 24-hour window than to appreciate.
Historical volatility patterns in Bitcoin's daily price action show that single-day moves exceeding 5% occur roughly 10–15% of the time across normal market conditions, though clustering around macroeconomic announcements or regulatory developments can shift this distribution sharply. The current probability assignment suggests traders view the June 3–4 window as a period of expected consolidation or mild downward pressure. Comparable intraday directional markets on Polymarket have typically seen YES probabilities range between 35–65% when underlying assets lack specific catalysts; the 1% here indicates either strong directional conviction toward weakness or perception of structural headwinds specific to that date.
Traders monitoring this contract should watch for scheduled macroeconomic releases in early June 2026—US employment data, Federal Reserve communications, or Treasury yield movements often trigger Bitcoin repricing within 24-hour windows. On-chain activity metrics, including large wallet movements or exchange inflows, can signal accumulation or distribution pressure ahead of the settlement window. Settlement occurs via USDC on Polygon, with conditional token mechanics allowing traders to exit positions before the 16:00 UTC close on 4 June if market conditions shift materially.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
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?
- Kalshi UK is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- 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.
- 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.
- 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.
