Prompt

Prediction market question (Crypto): "Bitcoin price on Apr 10, 2026?". The market currently prices YES at 99.00 cents (implied probability 0.990). What is YOUR probability that this market resolves YES? Your bankroll is $1000. 

Raw response

~0.97 — slightly below the market's 0.99, since the question's outcome condition is ambiguous to me and even strong markets carry a few percent of tail risk (expiry, definitional disputes, liquidity).
