Most “AI-powered” Polymarket bots are just fancy chat interfaces glued to a few API calls. They look impressive in demos but bleed money when left running unsupervised.
A sane, production-grade bot follows a strict, layered architecture where the LLM is only one small piece — and never the final decision maker.
The 6-Layer Pipeline
Layer 1: Hard Filter (Most Important)
Kill 95% of markets before any heavy computation:
- Minimum liquidity and order book depth
- Spread limits
- Resolution window sanity check
- Blacklist of ambiguous or high-dispute-risk markets
Layer 2: LLM as Research Assistant
Strictly scoped prompt that outputs structured JSON only:
- Precise resolution conditions
- Edge cases and ambiguity flags
- Base rates and watchlist items
Layer 3: Probability & Edge Engine
- Convert LLM output + external signals into calibrated probability with confidence interval
- Calculate real edge after fees, slippage, and resolution risk
- Only proceed if edge > threshold (typically 5%+)
Layer 4: Risk & Sizing (Hard Code, Not LLM)
- Immutable rules for position sizing (fractional Kelly, volatility-adjusted)
- Per-market and portfolio-level exposure caps
- Daily/weekly drawdown circuit breakers
Layer 5: Execution Hygiene
- Prefer passive limit orders when possible
- Size based on actual available depth (not theoretical)
- Smart order routing with IOC/FOK fallback
- Respect network latency and settlement timing
Layer 6: Monitoring & Logging
- Full decision trace for every trade
- Real-time alerts on anomalies
- Replay capability for continuous improvement
Key Philosophy
The LLM is a research assistant, not the trader.
All critical decisions (filtering, risk, sizing, execution) live in hard-coded, auditable rules that cannot be overridden by the model.
This separation is what separates bots that survive from those that look good on paper but blow up in live trading.
Why This Matters
Prediction markets move fast and have subtle edge cases (disputes, resolution ambiguity, liquidity crunches). A sane bot prioritizes survivability and consistency over chasing maximum win rate.
Build the rails first. Let the model make you smarter — not the one in control.
