Prompt
Prediction market question (Sports): "Shohei Ohtani: 2+ home runs?". The market currently prices YES at 7.00 cents (implied probability 0.070). What is YOUR probability that this market resolves YES? Your bankroll is $1000.
Raw response
My probability: **0.18** (18%). Willy Hutchinson is the more credentialed pro at light heavyweight; Ezra Taylor is a lesser-known opponent, and the market's 24% already looks like the high end of reasonable. I'll shade below the market given no strong evidence Taylor outclasses him, but with limited info I'm not deviating far.
