Wallets and exchanges with Polymarket access

28 ranked builders, $1.4B in attributed volume all time.

These are general-purpose wallets and exchanges that added a prediction-market tab rather than products built around one. They bring distribution, a custody model you may already trust, and fee schedules set by a much larger business. The interesting figure here is the measured rate: routing through a large wallet is convenient, and convenience is usually priced.

How these numbers are measured

Attributed volume is Polymarket's own builder leaderboard: the notional credited to each builder code, all time and over the trailing seven complete days. The measured fee is trader-paid fees per dollar of V2-attributed on-chain volume, derived from Polynode's indexed OrderFilled events, which is what a trader actually paid rather than what a rate card says. The declared fee is whatever the builder publishes, and it sits on each builder's own profile next to the measured one.
