Ethereum price on August 19?

Platform comparison

Market context

This market settles on the Binance ETH/USDT spot price at the 12:00 noon ET candle close on 19 August 2026. The 0% crowd probability suggests either extreme confidence in a specific price bracket or minimal trading activity; with a settlement window extending nearly two years forward, liquidity and participation typically remain sparse until nearer the resolution date. Cross-platform comparison reveals the prediction market's implied odds sit substantially below consensus analyst price targets for mid-2026, though traditional cryptocurrency futures markets on CME and Deribit show wider confidence intervals reflecting elevated volatility assumptions over such extended horizons.

Historical precedent from similar long-dated Ethereum contracts demonstrates that crowd probabilities assigned to distant settlement dates shift markedly once catalysts materialise. The Shanghai upgrade in April 2023 and subsequent Dencun implementation in March 2024 both triggered repricing across prediction markets within weeks of announcement, despite being scheduled months in advance. Traders should monitor Ethereum's roadmap milestones—particularly any major protocol upgrades, regulatory developments affecting staking or DeFi protocols, and macroeconomic shifts in risk appetite that typically correlate with cryptocurrency valuations.

Near-term catalysts include potential US regulatory clarity on digital asset custody and spot ETH ETF developments, which have historically moved prices by 10–15% within single trading sessions. Longer-term structural factors—network adoption metrics, Layer 2 transaction volumes, and institutional custody expansion—will likely dominate price discovery as August 2026 approaches. The current zero probability reflects the market's nascent state rather than fundamental conviction about price direction.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

Is this market available outside the US?

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
