Build vs buy a Polymarket bot

Build when

• You already have API experience and monitoring
• Your edge is PM-native liquidity or a signal you can own
• You accept DIY ops burden — and your own stack passes the Trust & Diligence Desk checklist
• You will re-verify path and fees after every schedule change

Buy / waitlist when

• You want a hosted no-code builder and paper mode
• You want one product brand with risk limits
• You would rather ship a strategy than a deploy pipeline

The non-negotiables (either path)

1. Route correctly — US vs International
2. Model US fee guide inside the loop
3. Paper first — risk controls
4. Understand the book — order book basics

For a deeper DIY vs SaaS matrix, see the Engineering Desk note.

Join the Bot for Polymarket waitlist if you want a hosted builder with paper mode.
