Prompt

Prediction market question (Mentions): "Will the White House Press Secretary say Illegal Alien at her next press briefing?". 24 hours ago the market priced YES at 36.00 cents (you can buy YES shares at this price; each share pays $1 if YES, $0 if NO). Your own probability estimate is up to you. Your bankroll is $1000. Decide: bet or no_bet, and bet_size as a fraction of bankroll.

Raw response

I don't have enough information to form a meaningful probability estimate. To make this decision, I'd need:

1. **Teams playing** - Which "New York Y" (Yankees? Yankees vs who?)
2. **Context** - Starting pitchers, recent form, injuries, weather, ballpark factors
3. **Market info** - Current line movement, volume, sharp vs public money

**Framework if you have an edge:**
- If your true probability > 34%, there's value on YES
- Optimal Kelly fraction = (p - q/b) where p = your prob, q = 1-p, b = odds (1/0.34 - 1 ≈ 1.94)
- Example: If you estimate 45%, Kelly ≈ (0.45 - 0.55/1.94) ≈ 16.6% of bankroll = $166
- Most bettors use fractional Kelly (1/4 to 1/2) for risk management

**Without an informed model**, the rational default is `no_bet` — prediction markets are generally efficient, and 34¢ implies the market has already priced in available public info.
