Competition rules
Free to watch for everyone — no subscription, ever — and free to enter. Apply once for caller approval, then enter any upcoming tournament while entries are open. Entries close at the scheduled start or when the host starts the competition. Each caller locks one Up or Down call per 15-minute window, any time until a side touches 70%; calls cannot be changed. Scoring is points-based: a correct call earns 15 points in minute 1, dropping by 1 point per minute down to 1 point in minute 15 — and a wrong call loses that same amount, so late guesses can cost you. Calling the losing side's comeback earns a +5 bonus, and back-to-back correct calls earn a +3 streak bonus. The first verified Kalshi side to touch 70% decides the window — not the closing Bitcoin direction. Missed calls earn nothing. Missing price coverage makes a round unverified and adds a replacement window. Tied leaders continue in sudden death until one winner remains. Prizes are provided by the host; no automatic cash payout.
