Prompt
Prediction market question (Economics): "Will average **gas prices** be above $4.155?". The market currently prices YES at 77.00 cents (implied probability 0.770). What is YOUR probability that this market resolves YES? Your bankroll is $1000.
Raw response
~0.77. I have no information that the market lacks on 2026 gas prices, so my probability tracks the market's implied 77% (YES above $4.155).
