Prompt
Prediction market question (Crypto): "XRP price up in next 15 mins?". The market currently prices YES at 61.00 cents (implied probability 0.610). What is YOUR probability that this market resolves YES? Your bankroll is $1000.
Raw response
60%. The market's 0.61 is close to fair for a 15-minute window, but I'd regress slightly toward 0.50 to account for bid-ask spread and market-maker fees embedded in the price. My honest estimate: 0.60.
