What price will Bitcoin hit on June 28?

Platform comparison

Market context

The real-world event at hand is the closing price of Bitcoin on 28 June 2026, a figure that will determine the settlement of a prediction market contract. Current market data shows Bitcoin trading near $59,590 on that date, with technical forecasts suggesting a minimum of $60,674 for June 2026 and a potential peak of $91,945 later in the year [2][3]. This context frames the current 0% implied probability for a "YES" outcome on higher price thresholds, as the asset sits just below the $60,000 mark that many contracts hinge upon [7][8].

Historical volatility provides a crucial lens for interpreting this probability. In early 2026, Bitcoin swung from a January high of $97,860 down to a February low of $60,074, before stabilising between $65,000 and $73,000 in March [5]. The asset reached its all-time high of $126,198 in October 2025 but has since retraced significantly, falling roughly $38,460 from its previous year’s level [1]. Such cycles suggest that while a rebound to $90,000+ remains technically possible, the immediate trajectory is constrained by recent downward momentum and institutional adoption rates that have not yet triggered the explosive growth some models predict [4].

Traders should monitor upcoming Federal Reserve interest rate decisions and US inflation data releases, as these macroeconomic dependencies heavily influence crypto liquidity. Recent analysis from Changelly indicates that Bitcoin’s value could increase by 3.88% to reach $62,762 by 30 June, contingent on broader market stability [2]. Platform mechanics also diverge sharply here: Polymarket often uses decimal odds with lower fees and no KYC, whereas Kalshi and Betfair rely on implied probabilities with stricter identity verification and higher fee structures, affecting how liquidity pools for this specific event [7]. These structural differences mean that the same underlying probability may be priced differently across exchanges, creating arbitrage opportunities for informed participants.

Which platform has the deepest liquidity?

Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.

Are all these platforms regulated?
