Mispricing Scanner

Where public prediction markets disagree — and why. Public prediction-market platforms run independently of one another. The same real-world question can end up listed in more than one place — worded a little differently, priced a little differently, closing on a slightly different date. Mispricer finds those moments and puts them side by side, so you can see the gap for yourself. Scan for disagreements, search markets on your own, or define your own research question and find matching listings. Save what you're following and build a local history over time. How it works: Refresh — the app pulls the latest open, publicly listed contracts from each supported source. Match — contracts are compared conservatively, so only genuinely equivalent questions get paired together. Review — for matched pairs, an optional AI-assisted check compares the exact contract wording and resolution rules, so you can tell a real difference from a wording quirk. Explore — search and browse normalized markets on your own terms, even when nothing has been automatically matched. Ask — describe your own research question and let Mispricer look for the closest matching public listings. Save — keep the pairs, markets and questions you're following in a simple on-device Watchlist, with local history over time. What Mispricer is not: it's not a trading platform, it doesn't execute trades or place orders, and it doesn't offer financial advice. It surfaces publicly available information for your own research — always verify both source listings directly before drawing any conclusion. Built to stay out of your way: no account required, no ads, no unnecessary permissions. An optional one-time Premium upgrade unlocks expanded research tools, unlimited saved items and longer local history.
