- https://github.com//mikhailtal-manifold-agent Python agent trading exclusively on MikhailTal markets using calibrated probabilities and Kelly sizing.
This repository (microprediction/manifoldbot) is a general-purpose Python package for building Manifold trading bots, with examples such as an LLM trading bot that compares GPT-generated probabilities to market prices and bets using fractional Kelly sizing.
Below are community-built bots that take this pattern in different directions. For each one, the focus is on what’s novel relative to manifoldbot rather than just re-implementing the same thing.
Repo: https://github.com/mostafazhrn/manifold_mikhail_bot
What it is:
A Python-based, GUI-enabled Manifold trading bot that targets markets created by MikhailTal,
combining classical machine-learning models with LLM-based reasoning (local models or OpenAI API),
optionally augmented with web-search analysis, to produce probability estimates and automated trades.
- Explicit ML training pipeline on resolved Manifold markets with per-option probability outputs
- Probability calibration that respects and incorporates live market probabilities rather than ignoring them
- Risk-aware final decision layer that blends ML estimates and LLM reasoning to gate and size trades conservatively
- Optional reasoning layer using either local LLMs (via Ollama) or hosted APIs (e.g. OpenAI)
- Web-search–augmented context gathering for markets with external information
- GUI-first design for strategy configuration, live monitoring, and experimentation
- Designed for extensibility beyond a single creator (default: MikhailTal)
Best for:
Users who want a flexible, GUI-driven Manifold bot that blends traditional machine learning
with optional local or API-based LLM reasoning.
Repo: https://github.com/jinanmh123/eliteBot/
What it is: A fully agentic hybrid Manifold trading bot, cleanly separating LLM-based semantic reasoning from quantitative decision-making, with regime-aware execution, volatility-adjusted Kelly sizing, realistic backtesting. Addressing key failure modes: (1) overconfident LLM probabilities, (2) purely technical strategies that miss semantic signals, (3) naive fractional Kelly overbetting in thin or unstable markets. Trading MikhailTal markets.
Novelty vs manifoldbot:
- Hybrid, but with hard safety boundaries: LLMs handle semantics only (language, evidence, uncertainty, blind spots), Technical models handle behavior only (price, volume, volatility)
- LLMs are forbidden from outputting probabilities, prices, or bet sizes. Agentic semantic reasoning without numeric authority Six-stage LLM pipeline (normalization, classification, base-rate context, evidence decomposition, uncertainty, constraints) Outputs are ordinal, schema-locked, cached, and deterministically mapped downstream, preventing hallucinated confidence and feedback loops
- Regime-aware signal fusion: Markets are classified as information-driven, noise-driven, or mixed, and this regime dynamically bounds how much semantic (LLM) versus technical evidence is trusted, preventing runaway conviction in ambiguous or noisy markets.
- Volatility- & uncertainty-aware Kelly sizing: explicitly scales bet size with Realized volatility, Liquidity, Aggregate model uncertainty and Market regime directly targeting the overbetting failure mode common in thin or ambiguous markets.
- Execution and backtesting realism: Regime-dependent execution; Time-ordered replay backtester with slippage and delay modeling; Reports ROI, drawdown, Sharpe, and Brier calibration (no hindsight)
Best for: Users who want a robust hybrid system that captures market semantics without trusting LLMs with money, and sizes risk using volatility and uncertainty rather than edge alone.

What it is: A “souped-up” Manifold bot using a multi-signal ensemble (historical performance, market microstructure, and an OpenAI LLM) to produce a single “true probability,” plus serious tooling for performance analysis.
Novelty vs manifoldbot:
- Multi-signal ensemble combining historical bias, order-book microstructure, and structured LLM forecasts
- Variance-aware LLM usage (multiple runs + disagreement penalty)
- Dedicated ensemble decision layer with edge calculation
- Advanced fractional Kelly with bankroll caps
- Built-in performance graphs and detailed rationale logging
- Configurable creator targeting (default:
MikhailTal)
Best for: Users who want a research-grade ensemble bot with excellent observability.
Repo: https://github.com/prathameshpatrawale/ppbot-ai
What it is: Contest-oriented bot built for the Manifold Featured Challenge, trading only MikhailTal markets.
Novelty vs manifoldbot:
- Pure technical strategy (no LLM): mean-reversion + momentum + liquidity filters
- Automatic simulation/real mode switching based on API key presence
- Simple PnL logging and one-click cumulative profit plotting
- Very clean, minimal modular structure
Best for: Lightweight non-LLM bots with quick setup and basic analytics.
Repo: https://github.com/Sbha8282/Manifoldbot-Ultra
What it is: Packaged, modular bot designed as a proper Python package with dry-run by default.
Novelty vs manifoldbot:
- Modern
src/layout with tests (Python 3.10+) - Session-cookie betting support (
MANIFOLD_SESSION_COOKIE) - Safe-by-default (
DRY_RUN=true) - Optional LLM layer (falls back to heuristics)
- Strict creator targeting via env var
Best for: Anyone wanting a clean, production-style package skeleton.
Repo: https://github.com/rodriguezramirezederdominic-web/TalOS-Manifold-Bot
What it is: Agentic bot using GPT-4 for reference-class reasoning and fractional Kelly sizing.
Novelty vs manifoldbot:
- Fully agentic LLM workflow (not just prompt → probability)
- Explicit fractional Kelly module for risk-of-ruin control
- Clear separation: trading loop, brain, and money-management files
- Hard-coded focus on a single creator
Best for: Studying readable “LLM-as-brain + proper bankroll management” designs.
Repo: https://github.com/H-tech-AFAQ-CEO/Best-Open-Source-Judgmental-Prediction-Python-Repository
What it is: Polished modular bot with both simple and LLM strategies.
Novelty vs manifoldbot:
- Full type hints, strong error handling, and logging
- Strategy base class with
SimpleStrategyandLLMStrategy - Integrated backtesting script
