Frequently Asked Questions

Kirkova is a sports prediction engine that generates win probabilities and player prop projections for NBA and MLB games using machine learning models trained on historical game and player data — no paid data feeds, no large language models, just statistical ensembles (XGBoost, LightGBM, and CatBoost) doing what they're good at.

No. Kirkova is an analytics and entertainment product. Predictions reflect model output, not certainty, and every game carries real variance — even a well-calibrated 65%+ confidence pick loses over a third of the time. Nothing on this site is financial or betting advice, and you should never wager more than you can afford to lose. See our track record for exactly how the models have actually performed, wins and losses included.

NBA and MLB are live today, with models retrained daily on fresh results. NFL and NHL support is planned for their next preseasons — see the sports coverage grid on the homepage for status.

These are confidence tiers based on the model's predicted win probability for its picked side: Sharp (65%+) is our highest-conviction tier — the bar we actually stand behind. Lean is a moderate edge. Passmeans the model sees the game as close to a coin flip and isn't confident enough to make a real call — shown for transparency, not as a recommendation.

Check the Performance page for the live, continuously updated record — broken down by confidence tier, with win/loss counts and ROI on a flat $100 stake. We show the full history, including cold streaks, rather than cherry-picked highlights.

Models retrain daily as new results come in, and predictions refresh automatically as odds and lineups move — the picks and props you see are generated close to game time, not once a day and forgotten.

No — Kirkova isn't a sportsbook and doesn't take wagers. We reference odds purely to calculate implied probability and ROI for our own track record. You'll need an account with a licensed sportsbook to actually place a bet.

Core picks and the public track record are free with an account. See Pricing for what's included in the free tier versus Pro.
