PolyBatch

One-click batch buy across multiple Polymarket bins: pick bins, set direction and share size, see combined cost live.

PolyBatch — Batch Order Assistant for Polymarket PolyBatch adds a lightweight panel to Polymarket event pages, letting you evaluate and place orders across multiple outcome bins in one guided flow — built for MULTI-LEG STRATEGIES such as covering a range of adjacent bins in the same event. What it does - Detects the outcome bins on the event page you're viewing and lists them in a compact side panel - Lets you pick multiple bins, set direction (Yes/No) and shares per bin - Shows live per-leg cost from the public order book, plus combined cost, total spend, and a clear profitable / will-lose verdict before you act - Places limit orders leg by leg through Polymarket's own trading interface, with a confirmation summary up front How ordering works (semi-automated by design) - You review and confirm the full order plan before anything is submitted - Each order is placed through the official Polymarket order form; every transaction still requires your own wallet signature (MetaMask, Magic, Phantom and others supported) - One leg at a time: the next order is only placed after the previous one is confirmed — with pause, skip, and abort controls at every step - Orders are limit orders priced from the visible order book; nothing is sent blind Privacy & security - No access to your private keys, seed phrase, or funds — signing happens exclusively in your own wallet - No account, no sign-up, no data collection, no analytics, no tracking - Reads only public, read-only Polymarket market-data APIs (order books and event metadata) - Runs only on polymarket.com; requests no browsing data from any other site Notes - Free to use - English and Chinese interface, switchable at any time - PolyBatch is an independent tool and is not affiliated with or endorsed by Polymarket - Prediction-market trading involves risk.
