Verdict: The best open-source, self-custody option for Polymarket automation. If you value transparency, control, and key security over convenience, OctoBot is the standout choice. The trade-off is that you manage your own infrastructure and the arbitrage module is still in development.

What OctoBot Prediction Market Does

OctoBot Prediction Market is a free, open-source bot purpose-built for Polymarket trading. Its primary live feature is copy trading — you identify a profitable wallet on the Polymarket leaderboard, enter its address, and OctoBot automatically replicates that wallet’s trades using your own funded account. The arbitrage module, which will detect price discrepancies across Polymarket markets, is under active development.

The bot is built on top of OctoBot, a broader open-source crypto trading framework by Drakkar Software. The Prediction Market variant strips down the interface to focus specifically on prediction market strategies, providing a clean UI designed for non-developer users while maintaining the technical depth developers expect.

The Self-Custody Advantage

OctoBot’s defining architectural decision is full self-custody. The bot runs entirely on your device — your computer, a cloud VPS, or even a Raspberry Pi. Your Polymarket private keys are stored locally and never transmitted to any external server.

This is a critical security distinction. Most Polymarket bots that operate through Telegram require you to send your private key to a centralized server for trade execution. If that server is compromised, your keys are exposed. With OctoBot, no external party — including the OctoBot team — can access your keys at any point. The security model is fundamentally different.

You can still connect OctoBot to Telegram for mobile notifications and monitoring, but the execution engine always runs on your hardware.

Deployment Options

OctoBot Prediction Market offers four deployment paths:

Desktop executables are pre-built binaries for Windows, macOS, and Linux available on the GitHub releases page. Download, run, and configure through the web UI.

Docker deployment uses the drakkarsoftware/octobot:predictionmarket-stable image. A single command spins up the bot with persistent storage for configuration, logs, and tentacles (strategy modules).

Source installation lets developers clone the repository, install dependencies, and run from source for full customization.

Raspberry Pi deployment enables low-power, always-on operation for about $5/month in electricity — ideal for copy-trading strategies that need to run 24/7 without cloud server costs.

Stack Layer Analysis

IdentityNoneNo agent identity integration
WalletSelf-custodyLocal key storage, no external key exposure
TradingFullPolymarket CLOB via API, order execution, position management
IntelligencePartialCopy-trading logic (wallet mirroring), arbitrage detection (in development)

OctoBot covers Layers 2–3 with emerging Layer 4 capabilities. It does not provide agent identity (Layer 1). The Intelligence layer is strategy-execution focused rather than AI-driven analysis — it mirrors other wallets’ decisions rather than making independent predictions.

Pros and Cons

Strengths:

  • Free and open-source. No subscription fees, no token requirements, no revenue share.
  • Self-custody key management is the most secure architecture available for Polymarket bots.
  • Visual UI eliminates the need to interact with raw code for basic strategies.
  • Paper trading mode allows risk-free strategy testing before deploying real funds.
  • Multiple deployment options including low-cost Raspberry Pi for always-on operation.
  • Active development with regular releases and responsive community.

Weaknesses:

  • Arbitrage module is not yet production-ready as of March 2026.
  • Self-hosted means you are responsible for uptime, updates, and troubleshooting.
  • Polymarket only — no Kalshi or sportsbook support yet.
  • Copy-trading is inherently reactive — you trail the wallet you’re copying, which means you get slightly worse prices on every trade.
  • No AI-driven analysis or autonomous decision-making. The bot copies others’ intelligence rather than generating its own.

Who Should Use OctoBot

OctoBot is the right choice for users who prioritize key security and transparency above all else, operators who want free automation and are comfortable managing their own infrastructure, developers who want an open-source codebase they can inspect, modify, and extend, and anyone who has identified profitable Polymarket wallets they want to mirror.

It is not ideal for non-technical users who want managed hosting, operators who need cross-platform support (Kalshi, sportsbooks), or traders who want autonomous AI-driven strategies rather than copy-trading.

Pricing

Free. Open-source. No fees of any kind.
