Hi Product Hunt 👋 Prediction markets went from niche to everywhere in about a year, and the first question most people have isn't "which market?" but "am I even allowed to use this?". The answer depends on where you live, and it changes by court ruling. I built PredictionMarkets.tools to answer that question and the ones after it. Every venue, API and tool fills in the same blocks: which regions it serves and whether it's open to US persons, who resolves the market and against what, what a fill costs (fees here come in four incompatible units), and how you get money out. Each block carries its own check date. Availability always does, because it changes without a changelog. Some pages I'm most glad exist: • Who decides the outcome: four different parties, each named in the rules • Why the same contract costs two prices on two venues • What to use instead of Augur, Dome, Metaforecast and eight others that closed
