Ethereum price on August 19?

Platform comparison

Market context

Ethereum's price at noon ET on 19 August 2026 will be determined by the closing price of the ETH/USDT 1-minute candle on Binance at that exact moment. The market currently shows 0% implied probability, suggesting traders expect either extreme volatility, technical settlement issues, or genuine uncertainty about whether Binance data will be accessible at resolution time. This is a binary outcome: the price either falls within a specified bracket or it does not, with ties resolving to the higher range.

Historical precedent matters here. Ethereum's volatility has ranged from under 5% to over 15% daily moves during major market dislocations, though such extremes cluster around macroeconomic shocks or regulatory announcements. The 0% probability reading is unusual for a liquid asset with two years until settlement; it typically signals either that the market is illiquid (few traders have priced it) or that the resolution mechanism itself carries execution risk. Kalshi and Betfair handle similar commodity-settlement markets with tighter spreads and clearer fee structures than some Polymarket books, though Polymarket's decimal odds display can obscure the true implied probability for casual traders unfamiliar with that format.

Traders monitoring this should track Ethereum's correlation with Bitcoin, Federal Reserve policy signals, and any Ethereum protocol upgrades scheduled before August 2026. The specific noon ET timestamp creates a dependency on US market hours; Asian or European price moves earlier that day will influence the final candle. Binance API reliability and any potential delisting or trading halts would constitute tail risks that current pricing may not fully reflect.

Methodology

This page compares Ethereum price on August 19? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. The live probability is the Polymarket mid; the comparison columns summarise each venue's fee structure, KYC, settlement currency and payment rails. Every CTA routes to Robinhood Prediction Markets, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.

FAQ

Polymarket vs Kalshi — which is better?

Depends on your location. Kalshi is CFTC-regulated, US-only with full KYC. Polymarket is global, on-chain, no KYC up to $1,500. Polymarket has ~10x higher liquidity but higher regulatory risk.

Is Betfair a Polymarket alternative?

Only partially. Betfair Exchange is UK-focused with a sports-betting emphasis; they have politics markets but with thinner liquidity than Polymarket. Settlement in GBP/EUR, 2-5% commission on winnings.

What about Smarkets as an alternative?

Smarkets is a UK betting exchange with a lower default commission (2%) than Betfair. Liquidity on political markets is below Polymarket, comparable to Kalshi. Geo-blocked in many jurisdictions.

Are all these platforms regulated?

No. Kalshi is CFTC-regulated (US). Betfair and Smarkets are UK Gambling Commission licensed. Polymarket operates without explicit regulation — a different risk profile than a regulated sportsbook.

Which platform supports Klarna/SOFORT?

Directly: none. Polymarket accepts only USDC on Polygon. Robinhood Prediction Markets offers a fiat on-ramp via Klarna or SOFORT (DE/AT/CH) and converts internally to USDC for the Polymarket order book. T+1 processing.
