Market context
Bitcoin is trading in a narrow band around the high-$70,000s, and this contract asks whether it will touch each strike level between 18 and 24 May before the window closes. On Polymarket, the market is already deep into the upper brackets, with the 78,000 level marked at 100% and 80,000 at 36%, while the current crowd-implied probability for the “No” outcome is 0%. That is notably firmer than the broader analyst range: CoinCodex has Bitcoin at about $78,268 today and projecting $78,717 by 21 May, then a drift towards $84,646 by 25 May, which suggests some upside remains but not enough to make the highest strikes certain.
Comparable short-dated Bitcoin contracts often turn on whether spot can hold a breakout for long enough to register on the relevant benchmark, rather than on a single intraday spike. Robinhood’s May 18 7pm EDT market uses the CF Benchmarks Real Time Index, with the final value taken from the average of the last 60 RTI prices before expiry, so late-session moves matter more than brief wicks. That benchmark dependence is important here too: traders should watch exchange-hours liquidity, any ETF-related flow, and broader risk sentiment rather than relying on headline price prints alone. Recent commentary has also been mixed, with some technical analysts arguing the trend remains bearish and eyeing lower support near $74,000 to $68,000, which is one reason the market’s upper-strike pricing still leaves room for disagreement.
Methodology
This page reviews What price will Bitcoin hit May 18-24? across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at PolyGram — the application we operate, where you trade directly against the Polymarket order book at 0% fees.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
