MarketMaster scans thousands of markets across every major venue in real time, models a fair value for each, and surfaces the mispriced ones — ranked by expected value, the second they appear.
Everything you need to find, validate, and act on an edge — in one fast, unified terminal.
Continuously ranks every tracked market by expected value, so the best opportunities float to the top automatically.
Each market gets a model-derived fair value and an EV edge — so you see why it's mispriced, not just that it moved.
Detects the same event priced differently across Kalshi, Polymarket and Predict.fun and flags the spread.
See $10k+ trades from sharp money the moment they hit — follow the whales across the market in one live feed.
Watchlist a market and get an email the instant price or edge crosses your threshold. No staring at screens.
Auto-imports your real trades, tracks realized P&L, win rate and a skill rating. Know if your edge is real.
Open the scanner instantly. Optionally link a read-only Kalshi key or Polymarket wallet to track your own trades.
The scanner ranks markets by EV and flags arbs. Every edge shows price, modeled fair value, and the gap — with the exact side to buy.
Trade on the venue you already use; MarketMaster records the result and grades your performance over time.
Use the scanner and analyzer free, forever. Pro unlocks alerts, the arbitrage feed, journal analytics, and the extension overlay.
No — and be skeptical of anything that does. MarketMaster is an information and analytics tool. It surfaces where markets may be mispriced and tracks your results honestly; it does not provide financial advice or guarantee returns. Prediction markets carry real risk of loss.
Fair value is our model's estimate of a market's true probability. The expected-value edge is the gap between that and the current price — a structured way to see which markets look mispriced.
Never. The journal uses a read-only Kalshi API key or your public Polymarket wallet address. We can't trade or move funds.
