Prompt

Prediction market question (Crypto): "Will Bitcoin reach $75,000 on April 14?". The market currently prices YES at 99.90 cents (implied probability 0.999). What is YOUR probability that this market resolves YES? Your bankroll is $1000. 

Raw response

**0.95** (95%).

Rationale: the market's 0.999 is my strongest prior, but prices above ~0.99 in crypto prediction markets are often illiquid and slightly overstated. I regress toward a genuine probability of ~0.95 — high, but not certain — to account for exchange/date ambiguity and thin-book bias.
