Overview
PredictEngine Pro is a commercial prediction market trading agent that bundles three core strategies — arbitrage, sentiment analysis, and momentum trading — into a single managed platform. It connects to both Polymarket and Kalshi, executing trades autonomously based on user-configured parameters.
The bot runs as a hosted service. Users configure their strategy mix, risk tolerances, and platform connections through a web dashboard. PredictEngine Pro handles execution, position management, and performance reporting. No self-hosting required, though the Enterprise tier includes a self-hosted deployment option for users who want full infrastructure control.
PredictEngine Pro launched in late 2025 and has built a user base primarily among semi-technical traders who want multi-strategy exposure without building custom infrastructure. The bot doesn’t promise returns — it provides a configurable execution layer and lets users tune the strategy parameters.
If you’re evaluating whether to buy a bot or build your own, our guide to buying prediction market agents walks through the key decision points.

Supported Strategies
Arbitrage
PredictEngine Pro’s arbitrage module monitors Yes/No spreads on binary markets and probability sums on multi-outcome markets across both Polymarket and Kalshi. It also detects cross-platform pricing discrepancies when the same underlying event is listed on both platforms.
The module executes both legs of a binary arbitrage simultaneously and includes partial-fill handling — if one leg fills but the other moves adversely, the bot can exit the filled leg or wait for the spread to re-emerge based on configurable patience parameters.
Minimum spread thresholds, position sizing, and maximum capital allocation per strategy are all user-configurable.
Sentiment Analysis
The sentiment module aggregates signals from news feeds, social media (X/Twitter, Reddit), and on-chain activity to generate directional conviction scores for active prediction markets. It uses a proprietary NLP pipeline trained on prediction-market-relevant language patterns.
When the sentiment score for a market crosses a user-defined threshold and aligns with favorable pricing (the implied probability hasn’t already moved to reflect the sentiment shift), the bot takes a directional position. Position sizes scale with conviction strength.
This strategy tends to perform well around major news events and poorly in quiet markets. Users can configure minimum conviction thresholds and maximum exposure per sentiment-driven position.
Momentum
The momentum module tracks price velocity and order flow patterns across active markets. It identifies markets where directional pressure is building — increasing volume, tightening bid-ask on one side, accelerating price movement — and enters positions in the direction of the trend.
Momentum trades include configurable trailing stops and time-based exits. The module works best on markets with high liquidity and active price discovery. It tends to underperform on thin markets where price movements are driven by single large orders rather than sustained directional flow.

Performance
PredictEngine Pro publishes aggregate anonymized performance data from its user base. These numbers represent median outcomes across active users for the 90 days ending February 2026. Individual results vary significantly based on configuration, capital, and market conditions.
| Metric | Starter (Arb Only) | Pro (Multi-Strategy) | Enterprise |
|---|---|---|---|
| Median monthly return | 2.1% | 4.8% | 5.3% |
| Median win rate | 89% | 72% | 74% |
| Median trades/day | 45 | 120 | 210 |
| Max observed drawdown | -3.2% | -8.7% | -9.1% |
| Sharpe ratio (annualized) | 1.8 | 1.4 | 1.5 |
Important caveats: These are median figures, not guaranteed outcomes. The arbitrage-only Starter tier has the highest win rate but lowest return because spreads are small. Multi-strategy tiers have higher returns but also higher variance and drawdowns. Past performance does not indicate future results. Prediction market trading involves risk of loss.
Pros and Cons
Pros:
- Multi-strategy in a single platform eliminates the need to run separate bots
- Both Polymarket and Kalshi supported natively, including cross-platform arbitrage
- Web dashboard makes configuration accessible to non-technical users
- Hosted service means no server management or DevOps overhead
- 14-day paper trading trial lets you evaluate before committing capital
- Active development with regular strategy updates
Cons:
- Starter tier is limited to arbitrage only and a single platform
- $149/mo minimum for multi-strategy access is expensive compared to open-source alternatives
- No self-hosting below Enterprise tier means you’re trusting a third party with API keys
- Sentiment strategy performance is inconsistent in low-volatility markets
- No support for platforms beyond Polymarket and Kalshi (Metaculus, Manifold, etc.)
- Backtesting data limited to 12 months of historical CLOB data
How to Get Started
- Sign up at the PredictEngine Pro website and start a 14-day free trial.
- Connect your platform accounts — you’ll need API keys for Polymarket and/or Kalshi. The dashboard walks through the key generation process for each platform.
- Configure your strategy — select which strategies to activate, set risk parameters (max position size, daily loss limit, capital allocation per strategy), and choose which market categories to trade.
- Run in paper trading mode for at least 7 days. Review the trade log and performance metrics to understand how the bot behaves with your configuration.
- Switch to live trading when you’re comfortable with the paper trading results. Start with conservative capital allocation and scale up gradually.
