Prompt

Prediction market question (Crypto): "Bitcoin price on Apr 16, 2026?". The market currently prices YES at 92.00 cents (implied probability 0.920). What is YOUR probability that this market resolves YES? Your bankroll is $1000. 

Raw response

~0.90. The market's 0.92 is the best available estimate; I shade marginally below to account for the vagueness of the resolution condition. At 92ยข a YES bet has negative expected value for me, so I'd stand aside.
