What PreciseEV does, where its numbers come from, and what they can and can't tell you.
Does PreciseEV place bets for me?
No. PreciseEV is a research and tracking workspace. You compare prices and evidence here, then place any bet yourself at a licensed sportsbook.
What does positive EV mean?
A bet has positive expected value when its price pays more than the fair, no-vig probability implies. It is an estimate over many bets, not a promise that any single bet wins.
Where do the numbers come from?
Player history comes from public datasets and box scores. Prices come from our odds data across 30+ sportsbooks, exchanges and pick'em apps. Every view shows its sample size, source and capture time so you can check it.
Which sports and sportsbooks are covered?
The NFL, NBA, WNBA, MLB, NHL and soccer, with prices from 30+ sportsbooks, exchanges and pick'em apps. Coverage of each market depends on what the books post.
Is the bet tracker free?
Yes. Every account includes the bet tracker and saved filters at no cost.
Are projections guaranteed?
No. Projections and simulations are experimental estimates under stated assumptions. Historical hit rates describe the past; they are not future probabilities.
