2 prediction markets price this story:

  • Will Zcash reach $2000 by December 31, 2026? — the market puts it at 24%, with $791 traded in the last 24 hours, closing 1 Jan 2027. The market resolves to Yes if the ZEC/USDT price on Binance hits $2000 at any point between now and 11:59 PM ET on December 31, 2026. It resolves to No if the price never reaches that level within this specific timeframe. Readers often mistakenly check prices on other exchanges or look at daily averages instead of the one-minute candle highs and lows on Binance.
  • Zcash's Orchard pool confirmed exploited? — the market puts it at 4%, with $400 traded in the last 24 hours, closing 5 Jun 2027. The Yes outcome requires proof that the specific June 4 Orchard pool vulnerability was exploited on Zcash mainnet before the fix activates by December 31, 2026. The No outcome applies if no such exploitation occurs or if credible sources do not confirm it within the deadline. Readers often mistake new exploits after the fix for the original vulnerability, which disqualifies them from resolving the market.

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.
