Market context
Ethereum’s price on 2 August is being priced as a very low-end outcome on the prediction market, with the current crowd-implied probability at **0% YES**, which is far below several public retail and analyst-style forecasts that still cluster around the low-to-mid $2,000s. That gap matters because comparable forecasts are not uniform: Changelly’s August 2026 range peaks around $2,747.11, Binance’s aggregation puts August at roughly $1,777 to $3,399 with a $2,588 average, and Coinspeaker’s dated August 2 call sits far lower, around $1,744.87 to $1,809.99[1][2][5].
For context, Ethereum’s longer-run forecast universe is still split between cautious and bullish camps, which makes a zero-priced contract stand out rather than confirm consensus. Recent market commentary has described ETH as starting August near $1,867 with weak volume and only a neutral-to-mildly bullish setup, while some technical models see a move towards $2,100–$2,180 if support holds[3][9]. On the cross-platform comparison side, Robinhood’s market shows 99¢ for ETH at $1,865 or above and 99¢ at $1,870 or above, suggesting its ladder is effectively near-certain on those lower thresholds, even though that does not translate into certainty on higher strikes[4].
Traders should watch the spot trend into the settlement window, because the event resolves on a specific timestamp and ETH can move sharply on macro headlines, ETF-flow updates, or protocol-related news before then. The main catalyst risk is a break above or below the current support zone: if ETH stays near recent levels, lower strike markets will remain dominant, but a sustained rally would quickly reprice higher bands that are now discounted in the contract and only partially reflected in analyst forecasts[3][10].
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
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.
FAQ
- 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.
- 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.
- 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.
