Institutional Overview

Polymarket’s institutional integration is for trading platforms that match counterparties themselves, such as request for quote (RFQ) venues. Your platform runs price discovery, and Polymarket settles each agreed trade as positions in its prediction markets. It is a separate integration from building on the order book: to place orders on the order book, start with Trading.

​

Request for Quote (RFQ) Trades

On the order book, prices are discovered by matching orders as they arrive. With an RFQ trade, price discovery happens on your platform instead: two counterparties agree on a price and size there, and your platform submits the agreed trade to Polymarket. Polymarket executes it on Polygon as one matched pair of signed orders, which never rest on the order book. Each counterparty authorizes only its own side, with a session key for its Polymarket Deposit Wallet. Your platform identifies itself with a partner API key, which does not authorize moving funds.

​

Same Markets and Positions as the Order Book

RFQ trades settle in the same prediction markets as the order book:

• Markets: an RFQ trade runs on a Polymarket market found through the public Gamma API, and its price is checked against that market’s order book midpoint.
• Positions: each counterparty receives standard Polymarket positions. They can be held, sold on the order book, or redeemed when the market resolves.
• Liquidity: your platform can use RFQ trades and the order book together to find the best price and liquidity for a market.
