Is Arena free to use?

Yes. Arena is free to download and use. You can place paper trades, track your portfolio, and send challenges without spending anything. A Arena Pro subscription unlocks additional features.

Is real money involved?

No. Arena uses virtual points only. You are trading on real Kalshi prediction markets, but no money is at stake. You cannot deposit, withdraw, or win real money through Arena.

How do challenges work?

Search any user by display name, then send a challenge — either a points race over a set period or a single-market head-to-head. The recipient can accept or decline. Results are scored automatically when the market closes.

What markets are available?

Arena surfaces live prediction markets from Kalshi, focusing on major US sports: NBA, NFL, NHL, and MLB. Markets include game lines, player props, and live in-game positions.
