Ethereum price on August 19?

Platform comparison

Market context

Ethereum's spot price at noon ET on 19 August 2026 will determine this contract's resolution, with settlement tied to the Binance ETH/USDT 1-minute candle close at that precise moment. The 0% crowd probability reflects either extreme confidence in a specific price range or minimal trading volume; Polymarket's conditional token architecture on Polygon means positions are collateralised in USDC, with settlement occurring on-chain once the Binance data feed confirms the closing price. Traders holding YES positions face execution risk if Binance experiences downtime or data anomalies during the resolution window.

Historical precedent suggests Ethereum's intraday volatility at noon ET typically ranges 1–3% on ordinary trading days, though this two-year horizon introduces substantial uncertainty. Major price movements on comparable dates have followed macroeconomic announcements or shifts in Bitcoin's trajectory rather than Ethereum-specific events. The current zero probability likely indicates the market has already priced in expectations for a particular bracket, or that liquidity remains concentrated elsewhere.

Catalysts materialising between now and August 2026 include Ethereum protocol upgrades, regulatory developments affecting staking or smart contract functionality, and broader cryptocurrency market sentiment tied to Federal Reserve policy. Recent volatility has correlated with US inflation data releases and technology sector performance. Traders should monitor Ethereum's Shanghai and subsequent upgrade schedules, as major network changes have historically triggered repricing across spot and derivatives markets.

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

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

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%.
