ABOUT
Why Sporacle exists
A weekly NFL forecast that publishes every number it makes, scores itself in public, and never sells odds.
What this is
Sporacle publishes win probabilities, margin ranges and fantasy projections for every NFL game and every ranked player, refreshed through the week. Every number carries the run that made it.
It is built by one person. There is no editorial desk and no expert consensus.
How the numbers are made
Each run forecasts the week from team ratings, player usage and injuries. The site shows the middle of each forecast as the call and its spread as the range. A published run is never edited after it goes live.

What we commit to
- Every number carries a run id and a timestamp.
- The track record scores every call, including the misses.
- Published artifacts are never rewritten; a correction is dated beside the original.
- No betting odds as content, no affiliate links, no accounts required.
- The closing line is the ceiling. A final game's page shows it beside our call.
Who makes it
Sporacle is a solo project. Questions, corrections and data requests go to [email protected].
