Bitcoin Up or Down on June 18?

Platform comparison

Market context

Bitcoin Up or Down on June 18?. The market is currently pricing the outcome at 5% YES, meaning crowd-implied probability sits at that level. Settlement is scheduled for 2026-06-18T16:00:00Z. Unlike a sportsbook, the price you see is set by buyers and sellers competing in a live order book — there is no house edge or bookmaker margin to fade.

Crypto price-target markets resolve on whether the underlying asset closes above or below a threshold at a specific UTC moment. The probability you see is the live integral of every trader's directional view, with no funding rate and no liquidation risk on either side.

Watch for the underlying catalysts that move this category: each official announcement, dataset release, or scheduled milestone generally produces a step change in the implied probability. Trades execute instantly on Polygon, and shares pay $1 each at resolution if your side wins.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket App UK, which mirrors the Polymarket order book directly.

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.
