What price will Bitcoin hit on June 28?

Platform comparison

Market context

The real-world event is the specific Bitcoin price level recorded at 5pm EDT on 28 June 2026, a fixed data point that determines the outcome of this prediction market. Historical patterns show Bitcoin has oscillated wildly, hitting an all-time high of $126,198.07 in October 2025 before retreating to roughly $60,074 in early 2026, with June 2026 prices hovering near $60,000 as ETF withdrawals dampen confidence[2][7]. The current 0% implied probability for a specific price target suggests the market views that level as statistically improbable given the asset’s recent volatility and downward pressure, mirroring past periods where support breaks led to dips toward $55,500[4].

A power-user approaching this programmatically would monitor conditional orders tied to US interest rate announcements and ETF flow schedules, as these dependencies directly impact liquidity and price stability. Recent reports indicate Bitcoin struggles to maintain value below $60,000 amid growing ETF withdrawals, with analysts warning a break in support could trigger a slide toward $55,500[4]. Traders should also watch for DeFi ecosystem recovery signals, led by AAVE and Solana, which might shift capital from semiconductors back into crypto, potentially stabilising prices near $60,300 despite rising rate concerns[4].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Polymarket Review UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
