Market context
Bitcoin's price action on 27 May 2026 will depend on macroeconomic conditions, regulatory announcements, and broader cryptocurrency market sentiment in the months leading to that date. The 1% implied probability suggests the market has assigned a very low likelihood to Bitcoin reaching a specific price threshold on that particular day—though the exact target price is not specified in the market description, making assessment of the probability's reasonableness difficult without that detail.
Historical volatility in Bitcoin pricing shows daily swings of 5–10% are routine during periods of moderate market activity, whilst sharper moves of 15% or more occur around major announcements or geopolitical events. The low probability here may reflect either an extremely high price target, an extremely low one, or simply the inherent difficulty of pinpointing a precise price on a specific date months in advance. Comparable single-day price prediction markets have typically seen probabilities cluster between 8–25% for directional moves within ±10% of spot price, suggesting this market's 1% reflects either an outlier scenario or a target well outside normal trading ranges.
Traders should monitor Federal Reserve policy signals, institutional Bitcoin adoption announcements, and any major regulatory developments from the SEC or international bodies through early 2026. Spot Bitcoin ETF flows, mining difficulty adjustments, and macroeconomic data releases in the weeks before late May will shape volatility expectations. Geopolitical tensions or corporate treasury announcements can move Bitcoin sharply; the specific settlement date means only price action on 27 May itself counts, eliminating the buffer of multi-day averaging.
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
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
- 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 Sport Prediction?
- Zero. Sport Prediction routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- 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.
