Market context
Bitcoin needs to finish the Binance BTC/USDT 1-minute candle at noon ET on 15 May above the contract’s strike level for a Yes. The market is already pricing that outcome at 100% implied probability, which leaves no visible disagreement between the prediction market and the crowd price, and little room for a meaningful edge unless a contract-specific misread emerges. That is a notably firmer stance than the broader analyst tone, which has been mixed: CoinCodex, for example, has BTC trading in the high-$70,000s to low-$80,000s across May, while other forecast pages cluster around roughly $80,000 as a central case. Recent spot references have also sat close to that zone, with Fortune putting Bitcoin near $80,120 on 15 May, suggesting the contract is being judged against a market that has already been hovering around the threshold rather than one far below it.
Historically, Bitcoin’s short-dated strike levels tend to hinge on whether price can hold a narrow band through the US session, rather than on the broader trend. 24/7 Wall St. has argued that the key technical line in May was the 200-day moving average around $82,228, while Binance’s own prediction page and other forecasters have recently pointed to a wide range of possible outcomes, reflecting how quickly BTC can move on macro headlines. For traders watching the window, the main catalysts are still US rate expectations, ETF flow data, and any abrupt risk-on or risk-off move in equities around the settlement day. Because the market settles on a specific Binance minute candle, the relevant question is less where Bitcoin trades at the close of the day and more whether the noon ET print is caught in a late-session swing or a brief liquidity flush.
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.
