Public prediction markets are great for elections. But your inside jokes, office drama, and friend group bets? Those stay between you.
Everything you need, nothing you don't.
Your markets are only visible to people you invite. No public profiles, no discovery, no strangers stumbling in.
Your predictions aren't indexed, searchable, or visible to anyone outside. What happens in your group stays there.
Get your own private space at yourgroup.poly.fan. Your link, your people, your predictions.
Admins control membership. Remove people, close the group, delete markets — you're in charge.
