Open Source Polymarket Bot Released
A group called The Cabal is releasing an open-source trading bot for the Polymarket prediction market. The launch is timed with a new token, aiming to provide traders with programmatic access to the platform.
The release of an open-source Polymarket bot enters a landscape where automated trading is becoming essential. In 2025, the prediction market industry saw over $44 billion in trading volume, creating a competitive environment where bots that can monitor hundreds of markets and execute trades in milliseconds have a distinct advantage. Existing open-source solutions include arbitrage bots that exploit price discrepancies between platforms like Polymarket and Kalshi, as well as frameworks for building custom AI-driven strategies. This new tool joins a growing ecosystem of programmatic trading solutions for Polymarket. Developers already have access to official Python and TypeScript SDKs, along with three distinct APIs: a Gamma API for discovering markets, a CLOB (Central Limit Order Book) API for real-time trading and price data, and a Data API for user-specific information like positions and trade history. For high-frequency strategies, Polymarket recommends using a Safe wallet to enable gasless and batched transactions. The timing of the bot's release coincides with Polymarket's plan to launch its own native token, expected to debut in 2026 after the platform's full relaunch in the United States. The platform's Chief Marketing Officer, Matthew Modabber, confirmed the token and a subsequent airdrop will follow the U.S. launch, prioritizing a responsible rollout with real utility. Speculation on the token's launch date has itself become a major market on the platform, attracting over $140 million in trading volume. Recent technical changes on the Polymarket platform have significantly altered the dynamics for trading bots. On February 18, 2026, Polymarket removed a 500ms taker quote delay and introduced dynamic fees without advance notice, rendering many existing taker bots obsolete overnight. This shift favors market-maker bots that can profit from rebates, rather than taker bots that now face escalating fees.
