Market context
Bitcoin's price action on 9 June 2026 will determine settlement of this contract, with traders currently pricing just a 1% probability of hitting the unspecified target level by market close that day. On Polymarket, this conditional token trades against USDC on Polygon, meaning positions require collateral in stablecoin form and settlement occurs through the platform's standard resolution mechanism once the settlement window closes on 10 June at 04:00 UTC.
Historical volatility patterns suggest Bitcoin's single-day price movements rarely exceed 15–20% under normal market conditions, though tail events do occur. The 2017–2018 cycle saw several days exceeding 10% moves, whilst the March 2020 pandemic crash produced a 50% weekly decline. More recently, the 2021–2022 bear market and subsequent recovery in 2023–2024 established precedent for sustained directional moves tied to macroeconomic announcements and regulatory developments. The current 1% implied probability reflects either an extremely high target price or an extremely low one—both statistically unlikely within a single trading session absent extraordinary market disruption.
Traders monitoring this contract should track Federal Reserve communications and inflation data releases scheduled near the settlement window, as these typically drive broad risk-asset repricing. Regulatory announcements from the SEC or international authorities can trigger sharp Bitcoin moves. On-chain metrics including exchange inflows and large holder accumulation patterns may signal positioning ahead of the date. Bitcoin's correlation with equities and the US dollar index remains a material dependency; equity market stress or dollar weakness could amplify volatility in either direction.
Methodology
We track What price will Bitcoin hit on June 9? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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.
- What does it cost to trade on Kalshi UK?
- Zero. Kalshi UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- 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.
