ABOUT PREDICTIONWINS
We're an independent editorial publication covering prediction market platforms. Our mission: help traders find trustworthy, regulated platforms — with full transparency about how we work and what we earn.
Who is behind PredictionWins?
PredictionWins is an independent editorial team that opens real, funded accounts on every platform we review. We rate Kalshi, Polymarket, ProphetX, OG, Novig and Rebet on fees, liquidity, regulation, and app quality, and disclose every affiliate relationship that earns us a commission.
Affiliate Disclosure
This commission does not influence our editorial content. Our scoring methodology is defined independently of affiliate relationships. We've declined partnerships with platforms we consider low quality or misleading.
Our review methodology
Real account creation
A reviewer opens an account with personal information and goes through full KYC. We don't accept demo accounts or PR walkthroughs.
Real money deposit
We deposit a minimum of $100 (or equivalent) in real money on every platform. The only way to test fees, deposit speeds, and real liquidity.
Live trading
We execute at least 5 trades across different market types, holding positions for varying durations. Limit and market orders where available.
Withdrawal test
We complete a withdrawal to verify processing times and fees match stated terms. Discrepancies are flagged in the review.
Scoring & peer review
Scores are assigned by the lead reviewer, then reviewed by a second team member before publication. Locked to the methodology below.

Editorial Independence
Our editorial team operates independently of our commercial team. Platforms cannot pay for positive coverage, higher scores, or preferential ranking. We've removed platforms from affiliate programs when their quality declined.
Platform representatives may provide factual corrections to published reviews. We welcome and appreciate this. However, editorial decisions — including scores and rankings — are made entirely by our reviewers.
