3 prediction markets price this story:
- Ethereum all time high by September 30, 2026? — resolved “No” on 1 Oct 2026. The outcome is Yes if a one-minute candle for ETH/USDT on Binance reaches a new all-time high between December 16, 2025, and September 30, 2026. The market resolves to No if no such price peak occurs within that specific timeframe. Readers often mistake the source of truth, but only Binance data counts, not prices from other exchanges or spot markets.
- Will the price of Ethereum be above $2,600 on September 11? — resolved “No” on 13 Sept 2026.
- Will Ethereum reach $3,200 September 7-13? — resolved “No” on 14 Sept 2026.
Odds are the market's probability that the outcome happens, updated every few minutes. They are information about what traders expect, not a forecast we make and not investment advice.
