What price will Bitcoin hit on June 28?

Platform comparison

Market context

The real-world event is the actual market price of Bitcoin at the close of trading on 28 June 2026, a figure that will determine the settlement of prediction contracts across global platforms. On Polymarket, traders currently assign a 100% probability to Bitcoin landing between £58,000 and £60,000, while the "<£56,000" outcome sits at 0% [1]. This contrasts sharply with Robinhood’s crypto market, where odds for "£60,000 or above" trade at 88¢, implying a significant divergence in implied probability versus decimal odds between the two books [8].

Historical volatility frames this current certainty; Bitcoin peaked at $126,198 in October 2025 before retreating to roughly $60,074 in early 2026, oscillating between $65,000 and $73,000 through March [7]. Recent data shows the price at $59,943 on 28 June 2026, aligning closely with Polymarket’s frontrunner [5]. While Changelly forecasts a minimum of $60,674 for June, the actual spot price has already dipped slightly below this technical floor, suggesting the market’s 100% confidence in the £58k–£60k band may be overly rigid given the asset’s erratic nature [4].

Traders should monitor the Federal Reserve’s interest rate schedule and any pending US cryptocurrency legislation, as these dependencies often trigger sharp price swings. Fortune reported Bitcoin at $73,459 on 28 May 2026, a drop of nearly $2,000 from the previous day, highlighting the sensitivity to macroeconomic shifts [3]. Platforms diverge here: Kalshi and Betfair typically require full KYC and offer decimal odds, whereas Polymarket allows non-custodial trading with implied probabilities and lower fees, creating distinct liquidity pools for the same underlying event [1].
