Market context
Bitcoin needs to trade to a stated price band at some point between 18 and 24 May for this market to resolve “yes”, with settlement due by 25 May. The current crowd-implied probability is 0%, which makes the market look priced as if none of the listed thresholds is expected to print within the window. That should be read alongside the venue rules and the underlying data source, rather than as a statement about Bitcoin’s broader medium-term direction.
For context, Bitcoin has been volatile enough that short-dated range markets can flip quickly on intraday moves, but this event is narrower than a simple end-of-week close because any hit inside the period can count. Regulatory and access frictions matter here too: in Germany, GlüStV rules shape whether a platform is treated as gambling-like, while US CFTC reach can affect how tokenised event contracts are offered and to whom. “No-KYC up to $1,500” generally means lighter identity checks for small balances or activity, which may make the market easier to access, but it does not change how the outcome is settled.
The main catalysts are macro and market-structure events: spot ETF flow headlines, any SEC or CFTC-related announcements, exchange outages, and large scheduled crypto data releases. Bitcoin was around $77,347 on 18 May, according to Fortune, which places the current levels close to several round-number thresholds on the market list. Traders will also be watching whether the prevailing short-term bearish tone persists, as that can pull price into or through the relevant bands even without a fresh fundamental shock.
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
- 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.
- 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.
