Kalshi BTC 15-minute markets
Plain answers to the questions traders ask most about Kalshi's bitcoin 15-minute markets: how a market is decided, why the price you pay matters more than how often you win, and how to judge a signal tool, SpectralEdge included.
Kalshi lists a new bitcoin market every 15 minutes, and each one asks a single question: will bitcoin's price at the close be at least what it was at the open? That sounds like a coin flip, and for most traders it ends up as one. These pages cover what actually decides a market, how prices turn into a break-even win rate, and what separates a real edge from a high win rate.
If you're new to these markets, start with how they settle. If you already trade them, the win-rate page is the one most people find useful. Each page links to its sources, including Kalshi's own contract terms.
