Zayn Predictions is free to download and free to use. Browse the full slate of calibrated market predictions, and reveal any pick's side and full reasoning with one quick ad — or go completely ad-free with a membership. Zayn Predictions is a research and analytics platform for prediction markets. We continuously scan hundreds of active markets, combine AI-powered signals with live data, and surface calibrated probability estimates — each one tagged with a confidence score and a short rationale you can read before deciding whether the prediction is worth your attention. We only surface predictions where the model is at least 70% confident, and the model is calibrated rather than optimistic — a 75% call should resolve correctly about 75% of the time. Live per-category accuracy stats are visible inside the app on the Stats tab so you can verify how the model is actually performing. WHO IT'S FOR • Kalshi and prediction-market traders who want a calibrated second opinion — and a live accuracy record — before they take a position • Sports analysts and modelers tracking edges across NBA, MLB, UFC, soccer, and the World Cup • Anyone who follows the odds and wants AI-backed picks with the full reasoning shown, not just a number WHAT YOU GET • Real-time predictions across multiple market categories, with full reasoning • Calibrated confidence scores — no hype, a 70% call is treated as a 70% call • Live accuracy tracking by category so you can audit model performance • Push notifications for high-confidence predictions • Reactions and a clean, distraction-free feed CATEGORIES COVERED • Sports — NBA, MLB, NFL, EPL, UCL, MLS, La Liga, Ligue 1, Serie A, UFC, World Cup 2026 • Weather — daily highs across major US cities • Crypto — BTC and ETH hourly strike markets • Fed — FOMC rate decisions and payrolls reports • Entertainment — music chart predictions PLANS • Free: download and use Zayn at no cost. Browse every prediction, and unlock any pick's side and full reasoning with a single short ad. Ad-supported, no subscription required. • Basic ($14.99/month): full access to every prediction across every category, with reasoning, accuracy stats, and push notifications. This is the research tier and is what we recommend to most users. • Pro ($29.99/month): everything in Basic plus Zayn Bot, an optional automation tier for power users who already participate in regulated prediction markets independently. You provide your own API key from your existing Kalshi account (a CFTC-regulated US derivatives venue) and the bot mirrors predictions to your account in categories you select. The app does not hold funds or open exchange accounts on your behalf. ABOUT PREDICTION MARKETS Prediction markets in the United States are regulated as commodity derivatives by the CFTC. They are distinct from sportsbooks and gambling platforms — pricing is transparent, contracts are standardized, and there is no house edge. IMPORTANT RISK DISCLOSURE Prediction-market participation involves real financial risk. Any contract can settle to $0.00 against you. Zayn Predictions provides research and calibrated predictions — we do not provide financial or investment advice, we do not guarantee outcomes, and past model performance does not guarantee future results. Never participate with funds you cannot afford to lose. You must be 18 or older and in a jurisdiction where prediction-market participation is legal.
