A private Polymarket is a prediction market that only invited people can see and use. Poly.fan gives your group its own space, such as acme.poly.fan. Members create yes/no or multiple-choice markets about anything, trade on the odds and compete on a shared leaderboard.
Sign up for free, pick a name for your space and you get your own subdomain. Share the invite link with your friends or team and create your first market. It takes less than a minute. You do not need a server, code or a crypto wallet.
Yes. Every feature is free: unlimited markets, unlimited members, leaderboards, Discord alerts and a custom subdomain. There is no per-seat pricing.
No. Markets use virtual points, not real money or crypto. Points have no cash value, so you do not need a wallet, a deposit or identity verification (KYC).
Polymarket is a public market for world events such as politics and crypto, with real money and markets that only Polymarket can create. Poly.fan is private: your group creates its own markets about anything, plays with free points and only invited members can see them.
Only the members of your group. Visitors who are not logged in see a login page, and group markets are not indexed by search engines.
Anything your group cares about: product launches, OKRs and sprint deadlines, sports games, office pools, esports, events or inside jokes between friends. You write the question, set the deadline and resolve the market.
Yes. Poly.fan works in any browser, and there is an iPhone app in the App Store.
