What price will Bitcoin hit in May?

Market context

Bitcoin is trading just under the key round numbers that dominate this market, with the contract now implying a 0% chance of a YES outcome. That makes the favourite anything that keeps BTC below the higher May thresholds, while the underdog is a late-month break into the next band. Polymarket’s own pricing shows the crowd clustering around the 80,000 level, with 90,000 and higher also listed as live outcomes in the 2026 market, while CoinCodex and Changelly have both published near-term forecasts in the high-$70,000s to low-$80,000s. That leaves the consensus squarely in a range trade rather than a decisive breakout call, and the value case sits with whichever side is underpriced once spot starts moving through the nearest strikes.

For comparison, this is the sort of event where outcome probabilities can look fixed until the last few sessions, then reprice sharply if price momentum changes. The main calendar risk is the monthly close itself: a late-May push above a round-number barrier can quickly flip attention from the nearest support band to the next upside level. On the catalyst side, traders will be watching ETF flow data, macro headlines on US rates and inflation, and any large move in risk assets. Changelly’s latest note points to a short-term bullish lean with a Fear and Greed reading in fear territory, while CoinCodex’s week-ahead path has BTC moving from the high-$70,000s towards the mid-$80,000s, which is the sort of drift that would matter most before settlement at 04:00 UTC on 1 June.

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

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.
