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

{"probability": 0.71, "confidence": 0.7, "reasoning": "Without the specific price range for Apr 15, 2026 in hand, the market's 71-cent price is my best calibrated estimate of the true probability, as liquid prediction markets price mid-probability events close to fair value."}
