Prompt

Prediction market question (Esports): "Total Kills Over/Under 28.5 in Game 1?". The market currently prices YES at 22.00 cents (implied probability 0.220). What is YOUR probability that this market resolves YES? Your bankroll is $1000. 

Raw response

My probability: **0.22–0.23 (22–23%)**.

Reasoning: I have no private information about the specific teams, so I anchor near the market's implied probability of 0.220. Kill totals in esports are highly volatile, so I'd only move meaningfully off the market with strong context (e.g., known defensive playstyles, slow pace, recent roster/strategy data). Lacking that, 22–23% is my best estimate, essentially deferring to the efficient price.
