What price will Ethereum hit on August 22?

Platform comparison

Market context

Ethereum must reach the stated price level by the market’s settlement deadline on 23 August 2026 at 04:00 UTC for a YES share to pay out; a NO share pays if it does not. With the current crowd-implied probability at 0% YES, the market is pricing that outcome as effectively out of reach.

That near-zero reading sits against a period of sharp but uneven ETH trading. Recent reporting put Ethereum around $1,900 on 17-19 August, then higher on 20 August, while other coverage noted an intraday push towards $2,300 before easing back. For a newcomer to prediction markets, that means the contract is not asking whether ETH is “high” or “low” in a general sense, but whether it touches the exact settlement threshold before the deadline.

The main catalysts are standard crypto drivers: spot ETF flows, broader risk appetite, and any fresh regulatory or policy headlines. U.S. spot Ethereum ETFs have recently posted large inflows, including about $189 million on 19 August and more than $220 million on 20 August, which helped support the price move. Traders will also watch whether that buying persists into the final session before settlement, because the market resolves on the recorded price at the deadline rather than on a daily close.

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.

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%.
