The ROI ProjectAbout the project
A research product, not a picks service.
The ROI Project makes historical betting-market data understandable, searchable, and auditable across eight sports.
Open research ↗Why it exists
Most products give you an answer. We built the place you inspect the evidence.
We originally explored the archive looking for profitable systems. That work exposed a better product: a research layer that keeps the context, exceptions, and underlying events visible.
Nothing here promises what happens next. The value is seeing what happened before, under conditions you can understand and verify.

Method
Four rules keep the archive honest.
Markets stay separate
Moneyline, spread, totals, and puck-line records are never blended.
Samples stay visible
Records, units, ROI, prices, and qualifying events travel together.
Time moves forward
Pregame views use only results completed before the listed matchup.
Labels have limits
Edge, Fade, Watchlist, and Descriptive summarize history, not picks.
Evidence language
Labels summarize strength, not certainty.
Positive historical evidence meeting the product's display rules.
Negative evidence useful as avoidance or opposing context.
Interesting evidence that remains limited or unstable.
Context shown for understanding without a directional claim.
