A 67-year-old retiree reportedly built an AI trading bot that made $290,000 in a year: 168 trades, a claimed 100% win rate and zero drawdown — figures that are unverified and should be taken with skepticism.
The strategy:
- Scans 188 events daily, filters for high-confidence predictions
- Uses 31 models to evaluate outcomes, rejecting trades below a confidence threshold
- Validates everything in paper-trading mode before risking real money
- Targets Polymarket contracts priced at 87–92¢ that may settle at $1
The core formula: Edge = Model Probability − Market Probability. It only trades when the estimated edge justifies the risk, collecting small per-trade profits on mispriced probabilities.
