Prompt
Prediction market question (Economics): "Will average **gas prices** be above $4.130?". The market currently prices YES at 5.00 cents (implied probability 0.050). What is YOUR probability that this market resolves YES? Your bankroll is $1000.
Raw response
My probability: **0.15** (15%). Rationale: I have no private information about ETH's price on that date beyond the market consensus of 14¢. Absent the resolution threshold details, the market price is my best anchor, and I'd only slightly adjust for typical market structure (fees/rounding) — landing near 15%.
