Market context
Ethereum needs to be above the contract’s strike at the Binance noon ET candle close, and the market is already pricing in a near-certain yes with a 100% implied probability. That is notably more aggressive than the broader crypto venue reads in the search set: Robinhood’s ETH price market shows a near-maxed line at 99¢ for a different August expiry, while prediction sites and exchange forecast pages are clustering much lower, mostly around the high-$1,700s to low-$2,000s rather than anywhere close to certainty above a fixed threshold.[17][14][11][15]
The historical framing is that Ethereum has recently been trading in the mid-$1,600s to high-$1,700s on several data feeds, with one Binance-linked historical table showing a July close of about $1,790 and another live-style feed putting ETH near $1,739 with an intraday range of $1,714-$1,784.[4][1] That matters because a 100% YES price only makes sense if the strike is comfortably below the prevailing market level at the exact settlement candle; if the contract is struck near or above spot, the crowd line would normally be far more conditional. Cross-platform, the contrast suggests either a very low strike, a stale listing, or a market that has already been arbitraged into a blunt binary outcome rather than a balanced price-discovery trade.[3][10]
For catalysts, traders should watch Binance’s ETH/USDT tape into the noon ET candle, because this market settles on that single one-minute close rather than a daily average or another exchange reference. Near-term direction is likely to be driven more by broad crypto risk sentiment, ETF-flow headlines, macro rates expectations and any Ethereum-specific network or regulatory news than by isolated technical levels, since even a brief wick around the settlement minute can decide the outcome. Forecast pages from Binance, Changelly and Gov.Capital all cluster around higher forward values than recent spot, but they still diverge materially, which underlines how dependent the contract is on short-horizon order flow rather than consensus longer-term valuation.[15][13][11]
Methodology
This page reviews Ethereum above … on August 5? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to Best Prediction Markets UK, which mirrors the Polymarket order book at 0% fees.
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.
