Ethereum Up or Down on August 13?

Platform comparison

Market context

This market tracks whether Ethereum's price will move upward or downward between two specific noon timestamps on consecutive days in August 2026. A YES share pays out if ETH/USDT closes higher at noon on 13 August than it did at noon on 12 August; a NO share pays out if the price falls between those two points. Traders who believe the price will rise buy YES shares; those expecting a decline buy NO shares. The settlement hinges on Binance's 1-minute candle data at precisely 12:00 ET on both dates, with an exact tie resolving the market at 50-50 odds.

The 0% implied probability on YES suggests the crowd currently expects Ethereum to decline or remain flat over this 24-hour window. Historical intraday price movements in Ethereum rarely show strong directional bias over such short periods; daily volatility typically ranges between 2–5% depending on broader market conditions. Comparable single-day prediction markets on major cryptocurrencies have historically shown near-even distributions when no specific catalyst is present, indicating that extreme probabilities often reflect either recent price action or anticipated news rather than fundamental directional conviction.

Traders monitoring this market should track macroeconomic releases scheduled for 12–13 August 2026, including any Federal Reserve communications or inflation data that could shift risk appetite toward or away from crypto assets. Ethereum's correlation with Bitcoin remains the primary driver of short-term directional moves; any significant Bitcoin volatility during this window would likely dominate price action. Exchange-specific technical levels and order-book depth on Binance at noon ET on both dates will determine execution prices, making real-time monitoring essential for settlement verification.

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 Prediction Market UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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%.
