Ethereum price on August 19?

Platform comparison

Market context

Ethereum's spot price on Binance's ETH/USDT pair will be sampled at a single point—the 1-minute candle close at noon ET on 19 August 2026—to determine settlement. This narrow temporal window eliminates intraday volatility as a factor; only the precise noon close matters. For traders building conditional order logic or backtesting against historical data, this specificity requires exact timestamp alignment with Binance's server time, not local exchange displays. The 0% crowd probability suggests either extreme confidence in a price outcome outside all listed brackets, or minimal market participation at this settlement date.

Historical precedent shows single-point-in-time Ethereum price markets cluster around major announcements or scheduled network events. The Shanghai upgrade in April 2023 and subsequent Dencun fork in March 2024 both produced sharp intraday moves, though neither guaranteed directional bias at a predetermined hour. Comparable markets on Ethereum's price at fixed timestamps have resolved across the full bracket spectrum; no bracket has demonstrated systematic overvaluation or undervaluation when sampled at noon ET specifically.

Traders should monitor Ethereum's macroeconomic calendar through August 2026, particularly US Federal Reserve communications and spot ETF flows, which have become primary drivers of intraday volatility. Programmatic approaches should account for Binance API latency when pulling historical 1m candle data for backtesting; the exchange's REST endpoints occasionally lag real-time pricing by 1–2 seconds. Any scheduled Ethereum protocol upgrade or major staking event announced before August would warrant scenario modelling against comparable historical price reactions.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Polymarket Review UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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%.
