Market context
Ethereum’s noon ET Binance print on 5 August will need to finish above the strike for this contract to pay out, and the market is currently pricing that outcome as certain at 100% YES. That stands in sharp contrast with external cross-platform indicators: Robinhood’s related ETH event shows a much more nuanced ladder, with 95¢ for $1,810 or above, 77¢ for $1,850 or above, and only 33¢ for $1,890 or above, while Binance’s own forecast page and other prediction sites are spread across a wide range rather than signalling certainty.[4][15][17]
Recent ETH prints argue for caution around any assumption of a one-way move. Investing.com shows Ethereum at $1,739.09 with a prior close of $1,789.47 and an intraday range of $1,713.95 to $1,783.97, while YCharts puts June 2026 at $1,665 and Fortune reported ETH at $1,844.64 on 3 August at 7 a.m. Eastern Time.[1][11][9] That mix of sub-$1,900 spot levels and broad forecast dispersion means the 100% crowd price is materially above the tone of the underlying market and looks detached from the kind of two-sided uncertainty seen on other venues.[3][12]
For traders, the key drivers are the short-dated macro and crypto-specific flows that can move ETH into the noon ET window: US market opens, same-day ETF-related sentiment, and any overnight risk-on or risk-off impulse into the US session. Binance’s own aggregated August outlook ranges from $1,777.09 to $3,399.15 with a $2,588.12 average, which underscores that the contract’s settlement depends on a single minute candle and can diverge sharply from longer-horizon “price in August” narratives.[15]
Methodology
We track Ethereum above … on August 5? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ
- 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?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
