Prompt
Prediction market question (Crypto): "Bitcoin price range on Apr 15, 2026?". The market currently prices YES at 71.00 cents (implied probability 0.710). What is YOUR probability that this market resolves YES? Your bankroll is $1000.
Raw response
My probability: **0.97** (97%). Rationale: Extreme-favorite prices near $0.99 in prediction markets are typically overpriced—the market's 1% loss probability understates realistic upset, injury/withdrawal, and rounding effects for a Round-of-32 tennis match. A ~2% gap below the implied 99% captures that distortion while staying near the market's strong signal.
