Builder

Definition

A Polymarket Builder is a third party that routes orders through the CLOB with attribution and earns builder fees. Builders submit trades on behalf of users or systems, include attribution headers accepted by the Polymarket Relayer, and appear on the Builder Leaderboard when eligible.

In context

You encounter Builders when routing orders to Polymarket’s CLOB: builders add attribution metadata to relayer requests and can receive a share of fees (paid in basis points). The Builder Program has three tiers—Unverified, Verified, and Partner—each with different daily relayer limits and rewards. Tiers determine the daily relayer limit (from 100 for Unverified up to unlimited for Partner) and access to rewards such as weekly USDC payouts for Verified and higher limits and support for Partner.

Builders interact with the same infrastructure you do: they rely on the Polymarket Relayer for gasless execution and the CLOB for matching. Maker fees on Polymarket are zero; builder fees are an extra revenue-share layer that may be applied to routed orders. Builders appear on the Builder Leaderboard when they opt in and meet program criteria.
