Polymarket Builders Program (2026): Builder Codes, Tiers and Rewards

What is the Polymarket Builders Program?

Polymarket's docs call it the Builder Program, and define a builder as "a person, group, or organization that routes orders from users to Polymarket." Trading apps, terminals and bots that place orders for their users all qualify. The program covers gas for wallet deployment, approvals and position operations through Polymarket's relayer, credits each matched order that carries the builder's code to its profile, and lets builders charge a fee on the flow they route.

You join with a polymarket.com account that serves as your builder account. It owns two different things. The builder code is public and goes on orders. The Builder API key, secret and passphrase are private credentials for relayer work such as deploying Deposit Wallets for your users, and they stay on your server. Keys and gasless transactions are covered in the Polymarket Relayer API guide.

How do Polymarket builder codes work?

A builder code is a 32-byte hex value assigned to your profile under Settings, then Builders, on polymarket.com. It is a field of the signed order struct rather than an off-chain label, so it must be set before the order is signed. Each settlement contract emits it in its OrderFilled event, on the CTF Exchange, the Neg Risk CTF Exchange and the Polymarket Protocol V2 Exchange, which makes attribution verifiable on-chain. The maker and taker of one trade can carry different codes, and each builder earns its own rate on its own side.

With the official TypeScript SDK, pass the code as builderCode. We type-checked this against @polymarket/client 0.12.0:

import { createSecureClient, OrderSide } from "@polymarket/client";
import { privateKey } from "@polymarket/client/viem";

const client = await createSecureClient({
  wallet: process.env.POLYMARKET_WALLET_ADDRESS!,
  signer: privateKey(process.env.PRIVATE_KEY!),
});

const order = await client.placeLimitOrder({
  assetId: "YOUR_TOKEN_ID",
  side: OrderSide.BUY,
  price: "0.52",
  size: "10",
  builderCode: process.env.POLYMARKET_BUILDER_CODE,
});

console.log(order);

The same code can attribute deposits and withdrawals through the Bridge API's optional X-Builder-Code header. Polymarket Perps has builder fields in its API too, but as of its 27 September 2026 release, attribution there is switched off and returns builder_codes_disabled.

What are the Polymarket builder tiers?

Relayer requests beyond the daily limit are rate limited and return an error. Verified builders can also receive weekly USDC rewards based on volume, plus grants, both subject to approval. Polymarket's tier table marks builder fees as available on every tier, while its Verified section lists fee monetization among the upgrade's unlocks, so confirm with Polymarket before you plan around fee revenue as an Unverified builder. If you trade only your own wallet and route no users, a Relayer API key gives you unlimited daily relay transactions without a builder tier.

How much can Polymarket builders charge?

A builder fee is a flat share of notional, notional * bps / 10000, so a 1,000 pUSD taker buy through a builder charging 100 bps pays 10 pUSD. It stacks on top of Polymarket's platform fee, which is taker-only and set per market, so a user on a fee-enabled market pays both. Changes are gated so users can see them coming: one rate change per 7 days, effective 3 days after it is scheduled, with only one pending change at a time. Earned fees go to the wallet tied to your builder profile, and Polymarket can revoke fee rights for activity it judges not to be bona fide.

Fee rates are public. GET https://clob.polymarket.com/fees/builder-fees/{code} returns builder_maker_fee_rate_bps, builder_taker_fee_rate_bps and enabled, and an unknown code returns 404. Across the 567 builders on the all-time leaderboard on 3 October 2026, 339 charged no taker fee, 122 charged the 100 bps taker maximum and 114 the 50 bps maker maximum. A few codes reported rates above the documented caps, so read a builder's live rate rather than assuming the cap.

How do you get the Polymarket builder leaderboard from the API?

The Data API serves it publicly, with no key:

Each leaderboard row carries rank, builder_name, builder_code, profile_image, verified, volume and active_users. Volume is counted in shares, not dollars, and active_users counts distinct makers in the window. Key on builder_code, because names are display data. This pulls the weekly top 10 with each builder's live fee rates, with Node 18 or newer:

const board = await (
  await fetch('https://data-api.polymarket.com/v2/builders/leaderboard?time_period=week&limit=10')
).json();

const rows = [];
for (const b of board.data) {
  const fees = await (await fetch(`https://clob.polymarket.com/fees/builder-fees/${b.builder_code}`)).json();
  rows.push({
    rank: b.rank,
    builder: b.builder_name,
    volume: Math.round(b.volume),
    activeUsers: b.active_users,
    takerBps: fees.builder_taker_fee_rate_bps,
    makerBps: fees.builder_maker_fee_rate_bps,
  });
}

console.table(rows);

In our checks on 3 October 2026, the weekly board listed 246 builders, every one marked verified, and the top 10 held about 65% of the week's volume. Polymarket keeps builder profiles and fee rates public on purpose, so users can see what a builder charges before using its app. Pulling the trader rankings instead is covered in the Polymarket leaderboard API guide.

How do you apply or upgrade as a Polymarket builder?

1. Create a builder profile. On polymarket.com, open Settings, then Builders. You start as Unverified right away, with no approval needed.
2. Integrate. Generate API keys with "+ Create New", attach your builder code to orders and use the relayer for gasless wallet operations.
3. Build volume. Route orders and show consistent usage.
4. Apply for Verified. Email builder@polymarket.com with your Builder API key, use case, expected volume and any links or decks. Polymarket says it responds within a few business days.

Verification status is displayed in your builder profile settings. Partner is the enterprise tier for high-volume integrations and strategic partners. Approved builders can also request Combo quotes for their users through Polymarket's Builder Gateway.

If your app shows Polymarket next to other venues, the Predictefy API serves its markets alongside 15+ other venues in one normalized schema.
