Prompt
Prediction market question (Crypto): "Ethereum price at Apr 3, 2026 at 5pm EDT?". The market currently prices YES at 14.00 cents (implied probability 0.140). What is YOUR probability that this market resolves YES? Your bankroll is $1000.
Raw response
Based on my research: today is after the resolution date, and ETH traded at ~$2,050–$2,060 at 5pm EDT on Apr 3, 2026 (CF RTI ~$2,053). Since I don't know the exact strike of this YES bucket, I'll give my best calibrated probability. **My probability: 0.15**
