Prompt

Prediction market question (Crypto): "Bitcoin price on Mar 28, 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

The question is under-specified — "Bitcoin price on Mar 28, 2026?" has no threshold (above/below $X?). Without the resolution condition I can't calibrate properly.

Assuming a typical "Bitcoin ≥ some level" market priced at 0.99, my probability is **0.98**. I'd shade slightly below the market price: extreme-priced markets (≥0.95) tend to overprice the favorite, and you've given me no independent signal beyond the market's own price.
