What is Bullpen?

The prediction workflow separates submitting an order, obtaining a fill and settling the eventual outcome. GTC and GTD orders can rest in the book, while FOK specifies immediate all-or-nothing execution. Resting orders can reserve balance, so cash, available buying power and held outcome units need to be read separately.

The wider app adds supported SVM and EVM wallet management, public trader discovery, following and rankings. Its mobile-friendly web interface includes notifications synchronized with the browser session. These shared surfaces do not make all products interchangeable: Polymarket positions are fully collateralized, and perpetual leverage or spot routing such as Jupiter should not be assumed to apply.

Who it is for

Users managing prediction and crypto positions in one workspace.
Traders seeking a mobile-friendly web terminal.
Researchers comparing public positions and leaderboard activity.

Features and coverage

Native prediction routing
Send prediction orders to Polymarket’s CLOB, with on-chain settlement on Polygon through the user’s proxy wallet.
Order lifetime and fill conditions
Choose GTC for orders resting until cancelled, GTD for time-expiring orders or FOK for immediate execution in full or not at all.
Book context
Inspect bid, ask, spread and available depth before submitting a marketable order. A displayed probability may differ from the price executable for your size.
Collateral and positions
Track collateral reserved by outstanding orders separately from remaining buying power, and follow filled outcome units through position management and resolution.
Wallet and social tools
Manage supported SVM and EVM wallets, inspect public positions, follow accounts and compare trader rankings.
Mobile web
Use the mobile-friendly interface and notifications synchronized with the browser session.

Workflows with Bullpen

Place a resting order

Select the exact outcome, inspect its order book and choose a limit price and lifetime. Monitor both order status and the collateral reserved while it remains outstanding.

Choose immediate execution

Compare available depth with the requested size. Use the documented all-or-nothing behavior when a partial fill would not suit the trade.

Research a public trader

Inspect public positions and history in the social view, then open the actual market before placing your own order.

Pricing and total cost

Prediction costs depend on the market and order. The integration guide distinguishes venue taker fees and maker treatment; inspect the order quote for the full execution cost. Token and perpetual fees belong to separate products.

Our take on Bullpen

Editorial rating: 3.5/5. Documented CLOB order conditions and collateral accounting make the prediction workflow understandable. The multi-asset interface still requires users to distinguish prediction costs and limits from token and perpetual products.

Frequently asked questions about Bullpen

Where are prediction orders executed and settled?

Bullpen routes prediction orders to Polymarket’s CLOB. On-chain settlement uses the user’s Polygon proxy wallet.

Can I apply perpetual leverage to a prediction position?

The documented prediction integration is fully collateralized; the app’s perpetual leverage does not carry over to those positions.

Why can available buying power be below my cash balance?

Outstanding orders can reserve collateral even before they fill. Inspect their reserved balance separately from held positions.

What other markets does Bullpen include?

The wider product includes on-chain spot assets and Hyperliquid perpetuals, with their own execution mechanics and fees.
