Ethereum price on August 19?

Platform comparison

Market context

The market prices Ethereum's ETH/USDT spot rate at the Binance 1-minute candle close at noon ET on 19 August 2026. The crowd currently assigns zero probability to any outcome resolving "Yes", suggesting either extreme uncertainty about the settlement mechanism or a view that the specified price bracket sits well outside realistic trading ranges for that date.

Historical precedent offers limited guidance here, since Ethereum's volatility profile has shifted materially across market cycles. During the 2021 bull run, daily swings of 10–15% were routine; the 2022–2023 bear and recovery phases saw tighter consolidation. A 0% crowd probability typically reflects either a bracket set at an implausible extreme (far above or below consensus fair value) or genuine ambiguity about whether Binance data will be accessible and unambiguous at settlement. Comparable spot-price markets on major exchanges rarely see zero probability unless the strike is positioned several standard deviations from the median forecast.

Traders should monitor macroeconomic policy signals and Ethereum network developments through mid-2026, particularly any material shifts in institutional adoption or regulatory clarity around staking and smart contract platforms. Binance operational status on the settlement date itself carries non-trivial tail risk; exchange outages or data feed disruptions have occasionally complicated historical resolutions. The current zero probability warrants scrutiny: either the bracket is genuinely uncompetitive, or early traders have simply not yet engaged with the market's mechanics and timeframe.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

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%.
