Make the call

Search any open Kalshi market, pick YES or NO, and set how confident you are. Or paste a Polymarket wallet to import positions.

02

We stamp it

The server records the price and the exact time from its own clock. No edits, no deletes, a two-minute window to cancel a typo.

03

Get the receipt

When the market settles you get a graded card: hit or miss, your Brier score against the market, closing-line value, and your rank. Invite friends and settle it on a shared leaderboard.

Why a Brier score?

Win rate rewards picking favorites. The Brier score measures how close your stated probability was to what actually happened, so calling a 30¢ long shot at 70% and hitting is worth far more than a 95¢ gimme. We show it next to the market's own implied Brier, so the number that matters is simple: did you beat the market?
