Sports predictions built around probabilities, calibration and transparent model tracking.
Diamond Forecast combines independent sport models with calibration, data-quality checks, best-bet qualification and parlay intelligence. The goal is not to promise certainty. It is to turn current sports data into clearer, measurable probabilities and keep score of how those probabilities perform over time.
Six sports, one forecasting platform
Diamond Forecast supports Major League Baseball, the NFL, college football and soccer. Each sport keeps its own model logic and inputs while sharing a common grading, calibration and performance framework.
Predictions before prices
The model creates its game prediction first. Sportsbook odds are evaluated afterward for price eligibility instead of being allowed to manufacture the underlying prediction. External prediction systems are used as benchmarks, not as hidden inputs to Diamond's own forecast.
Learning from every result
Completed games are graded into a shared outcome ledger. Confidence calibration, daily stability, experiment results, challenger models and parlay-leg performance can then be evaluated against the production champion without automatically rewriting the live model after one bad day.
Important: Diamond Forecast publishes probabilities and model analysis, not guarantees. Sports outcomes contain real uncertainty. Qualified picks and parlays can lose, and users should never wager money they cannot afford to lose.
