Market context
Bitcoin’s price path between 18 and 24 May is the real-world trigger here, and Polymarket is currently pricing the contract at 0% YES. That means traders are assigning no live probability to the relevant threshold being hit within the settlement window ending 2026-05-25T04:00:00Z. On Polymarket, positions are funded in USDC on Polygon and represented by conditional tokens, so the market price is the clearest read on how much value users are placing on a move before the close.
For context, Bitcoin has spent much of May below the mid-$80,000s, with 24/7 Wall St noting BTC around $78,000 and pointing to the 200-day moving average near $82,228 as the key level. That same report argued May trading was likely to stay in a $75,000-$85,000 range unless Bitcoin could reclaim that longer-term trend marker. Comparable Polymarket price contracts have also shown how quickly odds can harden around nearby round numbers when spot trades close to a strike, but they can fall back just as fast if price stalls beneath resistance.
A trader watching this market will be focused on spot moves, funding conditions and any catalyst that pushes Bitcoin through nearby levels before the 25 May cutoff. The most relevant inputs are macro headlines, ETF flow updates, large exchange movements and any schedule-driven liquidity changes across US trading hours. Recent market commentary from 24/7 Wall St and Changelly both put the near-term band around the high-$70,000s to low-$80,000s, which leaves the contract highly dependent on whether Bitcoin can break that range quickly enough for the market to resolve YES.
Methodology
We track What price will Bitcoin hit May 18-24? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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.
