Ethereum above … on August 18?

Platform comparison

Market context

This market settles based on Ethereum's price at precisely noon Eastern Time on 18 August 2026, using the one-minute candle close from Binance's ETH/USDT pair. A YES share pays out if that closing price exceeds the threshold stated in the market title; a NO share pays if it closes at or below that level. The current 100% probability assigned to YES indicates traders expect Ethereum to trade above the specified price at that exact moment—a narrow, time-specific bet rather than a broader directional view.

Ethereum's intraday volatility at fixed timestamps has historically ranged between 2–5% across similar one-minute resolution markets, depending on market conditions and the proximity of the threshold to prevailing price levels. During bull markets, noon ET closures have tended to cluster near daily highs, whilst bear phases show greater dispersion. The 100% crowd probability suggests the threshold is set substantially below current market expectations, or that traders view the August 2026 timeframe as sufficiently distant that downside risk appears minimal. Past prediction markets on Ethereum's spot price at specific times have resolved YES when thresholds were positioned conservatively relative to the settlement date.

Catalysts between now and August 2026 include Ethereum's scheduled Shanghai and subsequent network upgrades, macroeconomic policy shifts affecting risk assets, and regulatory developments in major jurisdictions. Bitcoin's price action typically influences Ethereum's correlation; sustained weakness in BTC has historically dragged ETH lower during intraday sessions. Traders should monitor Binance's system status and any trading halts, as technical outages could affect the official candle data used for settlement. The specificity of the noon ET timestamp means regional market open times—particularly Asian and European sessions—will have already concluded, potentially reducing volatility compared to US market open hours.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market 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.

UK Frequently Asked Questions

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
