About TopPredictions
Independent reviews and comparisons of the world's best prediction market platforms.
Our Mission
TopPredictions exists to help traders, forecasters, and curious minds find the best prediction market platforms for their needs. The prediction market industry is growing fast — new platforms launch regularly, regulations change, and it can be hard to know where to start.
We cut through the noise with honest, in-depth reviews based on real testing. We evaluate every platform on fees, liquidity, market variety, geography, regulation, and user experience — then present it all in one place so you can make an informed decision.
How We Review Platforms
Every platform we review is evaluated on the same criteria:
- Fees — Trading fees, withdrawal fees, and any hidden costs
- Liquidity — How tight the bid/ask spreads are, and how deep the order books go
- Market variety — Range of topics: politics, sports, crypto, economics, science
- Regulation — Legal status and regulatory oversight in key jurisdictions
- User experience — Ease of use, mobile app quality, onboarding process
- Trustworthiness — Track record, resolution process, and team reputation
Our Ratings
All ratings are our independent expert opinion. We are not paid by any platform to improve their rating. If we earn affiliate commissions from referral links (disclosed with "sponsored" labels), this has zero influence on our ratings or rankings.
Disclosure
Some links on this site are affiliate links — if you sign up through them, we may earn a commission at no extra cost to you. These are always labeled. Our ratings, reviews, and rankings are completely independent of any commercial relationships.
