Market context
Bitcoin's price trajectory during the final week of May 2026 will depend on macroeconomic conditions, central bank communications, and spot-trading volume across regulated and unregulated venues. The 4% implied probability reflects market consensus that a specific price threshold—likely in the upper range of historical volatility—remains unlikely within that narrow window. Settlement occurs on 1 June 2026, giving traders a hard deadline to assess whether price action has met the market's criteria.
Comparable markets from 2024–2025 show that weekly Bitcoin price targets with sub-5% probabilities typically require either geopolitical shock, major regulatory announcement, or extreme leverage liquidation to resolve YES. Historical precedent suggests that when crowd probability sits this low, the threshold itself is pitched beyond two standard deviations of recent price movement. Traders should examine whether the May 25–31 window coincides with any scheduled Federal Reserve communication, which has historically moved Bitcoin 3–8% intraday.
Regulatory accessibility affects who can trade this market. Under Germany's GlüStV (gambling licensing framework), prediction markets on crypto assets face stricter oversight than traditional financial derivatives. US CFTC jurisdiction covers Bitcoin futures but not spot-price prediction markets directly. No-KYC trading up to $1,500 notional exposure remains available on some platforms, though this market's settlement value may exceed that threshold depending on the price target. Traders should verify their jurisdiction's treatment of crypto prediction markets before entry, as regulatory status varies significantly between UK, EU, and US venues.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ
- Is this market available outside the US?
- PolyGram 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.
