Market context
Bitcoin's price action on 25 May 2026 will determine settlement of this contract, with traders on Polymarket currently pricing the YES outcome at zero probability. The settlement window closes on 26 May at 04:00 UTC, meaning any price movement on that specific calendar date—whether intraday spike or sustained level—becomes the reference point. On Polygon-based Polymarket infrastructure, positions are held as conditional tokens backed by USDC reserves, allowing traders to exit or adjust exposure right up until the settlement oracle resolves the precise price level.
Historical Bitcoin price movements show single-day swings of 5–15% occur regularly during periods of macroeconomic volatility or major regulatory announcements. The 0% crowd probability reflects either extreme confidence that Bitcoin will not reach a particular threshold on that date, or insufficient liquidity and interest in this specific contract variant. Comparable single-date price prediction markets have seen sharp repricing when major catalyst windows approached, particularly around Federal Reserve decisions or significant cryptocurrency policy shifts that traders had initially discounted.
Traders monitoring this contract should track scheduled events in the months leading to May 2026: potential interest rate decisions from central banks, regulatory announcements from the SEC or international bodies, and major cryptocurrency exchange developments. Bitcoin's correlation with traditional equity markets and the US dollar index remains a primary driver of directional bias. Recent volatility clustering suggests that any significant macroeconomic shock in early 2026 could shift the implied probability substantially, even if the underlying spot price remains range-bound.
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 PolyGram?
- Zero. PolyGram 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.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
