Ethereum above … on August 21?

Platform comparison

Market context

This market settles on Ethereum's price at a specific moment: the close of the 1-minute candle on Binance's ETH/USDT pair at noon Eastern Time on 21 August 2026. The resolution hinges on a single data point—the closing tick of that 60-second window—making it a precise instrument for testing execution timing or validating conditional order logic across exchanges.

The 100% crowd probability reflects the difficulty of predicting a price floor two years forward with meaningful precision. Historical precedent suggests such long-dated, single-candle markets typically attract low conviction early on; Ethereum's volatility profile means even modest price targets can shift dramatically across market cycles. Comparable markets on fixed future dates have seen probability drift sharply as settlement approaches, particularly when the threshold sits near plausible trading ranges rather than extreme levels. The current reading likely indicates either an extremely conservative price target or sparse initial participation.

Traders building automated systems should note that Binance candle data feeds require explicit handling of timezone conversion and exchange-specific data latency. Any bot or conditional order targeting this resolution would need to query Binance's API directly at the specified timestamp, accounting for potential clock skew and the distinction between trade execution time and candle close time. Monitoring Ethereum's macro catalysts—regulatory developments, network upgrades, or shifts in institutional adoption—matters less here than ensuring your data pipeline correctly timestamps the noon ET close on the settlement date itself.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.

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%.
