Pronóstico: What price will Bitcoin hit on June 28?

Platform comparison

Market context

Bitcoin’s price on 28 June 2026 is the real-world event this contract settles on, with the current Polymarket listing showing a 0% implied probability for any “yes” outcome above the threshold. On-chain, the market uses USDC on Polygon and conditional tokens to automate payouts once the CF Benchmarks Bitcoin Real-Time Index is verified at 5pm EDT.

Historical patterns frame this near-zero probability: Bitcoin peaked at $126,198 in October 2025, then fell to $60,074 in early 2026, and hovered around $73,459 on 28 May 2026 before dropping further [1][6]. Recent data shows the price at $59,943 on 28 June 2026, confirming a sustained decline from mid-year highs [4][9]. Changelly’s forecast also suggests the price will not drop below $60,674 in June 2026, yet actual trading has breached that level [3].

Traders should watch for Federal Reserve interest rate announcements, Bitcoin ETF inflow reports, and any regulatory updates from the US SEC, as these directly impact short-term volatility. A recent Fortune article noted Bitcoin’s 3.88% projected rise by 30 June 2026, but actual market data contradicts this optimism [1][3]. Institutional adoption trends and global M2 money supply changes remain key dependencies for any potential reversal [5].

FAQ

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Argentina trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
