Market context
Bitcoin's price action on a single day in May 2026 depends on volatility clustering, macro sentiment shifts, and event-driven moves across a 17-month window. The crowd has assigned zero probability to this outcome, suggesting either extreme confidence in a narrow range or genuine uncertainty about which price level the market is testing.
Historical precedent shows Bitcoin has touched multiple price milestones within single trading days during bull and bear cycles. In 2021, daily swings of 10–15% were routine; in 2023–2024, intraday volatility compressed significantly as institutional adoption deepened. The zero probability reading here likely reflects either a price target so far removed from consensus forecasts that traders dismiss it outright, or insufficient liquidity in the order book at that specific level. Comparable single-day price targets in crypto markets typically attract non-zero odds unless they sit beyond three standard deviations from the median forecast.
Catalysts entering May 2026 include US monetary policy signals from the Federal Reserve, potential spot or futures Bitcoin ETF developments, and geopolitical risk events affecting risk-on appetite. Regulatory announcements from the SEC or international bodies can compress or expand intraday ranges sharply. Miners' behaviour during difficulty adjustments and large holder movements (tracked via on-chain analytics) often precede volatility spikes. The settlement window's precision—ending 25 May at 04:00 UTC—means traders must account for timezone-specific trading sessions and whether the target price needs to be touched or closed at that level.
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
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
FAQ
- Where can I trade this market with the lowest fees?
- On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- 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 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.
