What is Bullpen?

Bullpen brings several markets into one app while retaining their different execution mechanics. Prediction orders route to Polymarket’s CLOB and settle through the user’s Polygon proxy wallet. The product also provides social discovery, positions and rankings. Its prediction-market documentation explains the distinction between resting orders, immediate fills, collateral reservations and eventual settlement.

Workflows with Bullpen

Place a resting prediction order

Choose the exact outcome, inspect its book and submit a limit order with the intended lifetime. Monitor both the order and the collateral it reserves.

Use immediate execution deliberately

Compare a marketable order’s available depth with the requested size; use the documented all-or-nothing behavior when partial execution is unsuitable.

Research another trader

Review public positions and history from the social view, then inspect the relevant market directly before creating your own order.

Pricing and total cost

Prediction-market costs depend on the order and market. The integration guide describes venue taker fees and maker treatment; the order quote is the place to check the full execution cost. Fees for the app’s token and perpetual products are separate.

Getting started

Before you start: Polymarket positions in the documented integration are fully collateralized; the app’s perpetual leverage does not carry over to them.

Open the Bullpen app and complete account creation.
Set up the intended wallet and prediction-market collateral using the dedicated guide.
Open a prediction event and select its outcome.
Review bid, ask, depth and the order’s time-in-force.
Submit the order and inspect its fill or resting state.
Monitor reserved collateral, held shares and settlement separately.

Our take on Bullpen

Documented CLOB order types and collateral handling make the prediction integration understandable. The broad multi-asset interface requires users to separate prediction costs and limits from token and perpetual products.
