Polymarket Developers
The Builders Program - fees, weekly rewards and grants
If you can write code, Polymarket pays differently than it pays everyone else. Route your users' orders to the exchange and you set your own fee on that flow - up to 1% - collect a share of a weekly USDC pool, and become eligible for a grant fund of $2.5 million and up. Here is how each of the three works, and which parts Polymarket has not published.

What You're Building On
Two things worth knowing before you write a line of code: what counts as a builder, and whose order book you are plugging into.
Who counts as a builder
In Polymarket's own words, a builder is a person, group or organization that routes orders from users to Polymarket. Your app, bot, terminal or widget sends orders to the exchange's order book, each one carrying your builder code, and everything that flows through it is attributed to you.
That attribution is the whole mechanism. It decides the fee you collect, your slice of the weekly pool, your position on the public leaderboard and how seriously a grant application is taken.
Matched volume takes up to 24 hours to appear on the leaderboard at builders.polymarket.com.
Why this order book
You are integrating with the deepest liquidity in the category, backed by the company that owns the New York Stock Exchange and freshly relaunched in the US as a regulated venue. Apps already in the program route hundreds of millions of dollars in volume, and the leaderboard is public - you can see exactly who drives what before you commit.
Who founded Polymarket, every funding round and how the markets themselves work - in our guide.
Three Ways It Pays
They stack - the same routed volume can earn you a fee, a share of the weekly pool and a case for a grant at once.
1. Builder fees
Your own flat percentage on every trade routed through your app - you choose the rate within the caps. This is the predictable part of the income and the one you control.
2. Weekly USDC rewards
A pool split between builders by share of attributed volume. Epochs run Sunday 00:00 UTC to Saturday 23:59 UTC; the program started on 2 November 2025.
3. Grants
More than $2.5 million committed, awarded on product traction rather than raw volume alone. Verified builders can also get engineering and marketing support.
Builder Fees, In Detail
This is the part with hard numbers in the official documentation - and the part with the highest ceiling.
The caps and the rules
| Fee | Maximum | Step |
|---|---|---|
| Taker | 100 bps (1%) | 1 bp (0.01%) |
| Maker | 50 bps (0.5%) | 1 bp (0.01%) |
The fee is a flat percentage of trade notional: builder_fee = notional × rate_bps / 10000. A 1,000 pUSD taker buy routed at 100 bps returns 10 pUSD to you. Rates can be changed once every 7 days, and a change takes effect after 3 days' notice - so pricing is a decision, not a dial you twist daily.
What that looks like in money
Arithmetic from the published formula, not a forecast - and it assumes every routed trade is a taker trade at your full rate.
For comparison, the referral program pays 10% of Polymarket's own fee on referred users - roughly 0.2% of their volume, for 30 days, with no code to write. The Builders Program asks for real software and pays several times more per dollar routed, with no time limit.
How to Join
The basic level is permissionless - there is no application form standing between you and your first attributed order.
Get your builder code
On polymarket.com open Settings → Builders and copy the code. It is a bytes32 identifier tied to your profile.
Attach it to orders
Send orders to the CLOB with your code attached - that is what makes the volume yours for fees, rewards and the leaderboard.
Use the relayer
Route wallet deployment, approvals, execution and CTF operations through the relayer - gas is covered, so your users never touch it.
Set your fee, then apply
Choose your taker and maker rates, then go for verification and a grant once you have traction to show - a badge, support and engineering help come with it.
What people actually build
Polymarket points builders at two broad directions: embed markets inside an app you already run, or serve a specific vertical or geography; and build a pro terminal - advanced order types, analytics, portfolio management, AI-assisted decisions.
In practice the leaderboard is full of trading front-ends, Telegram bots, sports-focused apps and analytics tools. The common thread is not cleverness, it is distribution: whoever already has users routes volume, and volume is what the program pays for.
Worth noting: the rewards go to the interface, not the idea. A modest wrapper with a real audience out-earns a brilliant tool nobody opens.
The lowest-effort entry point is usually a bot on a channel you already own - it needs no app store, no design team and no marketing budget, and it starts routing volume the day it ships.
What isn't published
We only put numbers on this page that Polymarket states itself. Three things it has not disclosed, and you should be sceptical of anyone quoting them precisely:
The $2.5M+ grant commitment is public and confirmed by Polymarket's own developer account; the detailed process is still "stay tuned". Third-party estimates of "0.5-1% of routed volume" for weekly rewards are guesses by outside trackers, not program terms.
Builders Program FAQ
What is the Polymarket Builders Program?
It is Polymarket's program for developers who route user orders to the exchange. A builder is a person, group or organization sending orders from its own app, bot or interface. Orders carrying your builder code are attributed to you, which unlocks three things: a fee you charge on that flow, a share of weekly USDC rewards, and eligibility for grants.
How much can a developer earn on Polymarket?
You set your own fee on the volume routed through your app, within Polymarket's caps: up to 100 bps (1%) on takers and 50 bps (0.5%) on makers. A 1,000 pUSD taker buy at 100 bps returns 10 pUSD. On top of that come weekly USDC rewards and grants.
How do I join?
Go to polymarket.com → Settings → Builders and copy your builder code. Attach it to the orders your app submits to the CLOB, and route wallet operations through the relayer for gasless flows. There is no application form for the basic level - the protocol is permissionless.
How big are the grants?
Polymarket has publicly committed more than $2.5 million to builder grants, awarded to teams that show real product traction rather than raw volume alone. A detailed application form and scoring criteria have not been published, so treat any precise grant figure you read elsewhere as an estimate.
How do the weekly USDC rewards work?
A weekly pool is split between builders by each one's share of total attributed volume. Epochs run from Sunday 00:00 UTC to Saturday 23:59 UTC, and the program started on 2 November 2025. The exact formula and the pool size for a given week are not published.
Do I need a licence or a company?
The protocol is permissionless - you can start routing orders with a builder code and nothing else. What you need beyond that depends on your product and your jurisdiction, especially if you touch user funds or serve regulated markets. That part is on you, not on Polymarket.
What is the relayer and why does it matter?
It covers gas for on-chain operations - wallet deployment, approvals, order execution and CTF operations - so your users never need the native token or an explanation of gas. For a consumer app that removes the biggest onboarding obstacle in crypto.
How long until my volume shows up?
Matched volume attributed to your builder profile can take up to 24 hours to appear on the public leaderboard at builders.polymarket.com.
What can I actually build?
Embed markets in an app you already run, serve a niche vertical or geography, or build a pro terminal with advanced orders, analytics, portfolio tools and AI-assisted decisions. Anything that routes real orders gets attributed.
Is this the same as the referral program?
No. The referral program pays 10% of Polymarket's trading fees from users you refer and needs no code, but only for their first 30 days. The Builders Program pays on the volume your software routes, at your own rate, with no time limit - more work, higher ceiling.
