How HaterPicks works

How does the model work?

Instead of starting from a sportsbook's price, HaterPicks starts from a projection. For each player and market it covers — passing yards, points, rebounds, hits and so on — the model estimates the most likely outcome from that player's recent form, role, matchup and the pace of the game, and turns that into a projected line and a hit rate. It then lines that projection up against what the sportsbooks are actually offering, so you can see where the model and the market disagree. Each sport has its own model, because the way form translates into an outcome is different in the NFL than in the NBA, MLB or the NHL.

The projection is only ever as honest as the number behind it, which is why HaterPicks reports how often those projections actually land rather than only showing the ones that won.

What is closing line value (CLV), and why grade on it?

The closing line is the final price a market settles on just before an event starts — after all the money, news and sharp opinion has gone in. It is the single best publicly available estimate of an outcome's true probability. If you consistently take a price that is better than where the market closes, that is the strongest sign available that your bet had genuine value, independent of whether that particular bet happened to win or lose. That is why the bets you track in HaterPicks show the closing line beside your price, not just the scoreboard: a good bet that loses is still a good bet, and the closing line is how you tell them apart.

We explain this in full, with examples, in what is closing line value. If you are new to the underlying math, start with what is expected value in betting.

How do we report accuracy?

Every projection the model makes is graded against the result once the game is final, and each sport's hit rate is published on the site — wins and losses. There is no hidden record and no cherry-picking of the good weeks. Across the last 30 days, HaterPicks graded 4,118 player-prop projections in US sports and the model was right on 53.1% of them.

That figure moves as new results come in and varies by sport and market. It is a record of what the model has done, not a promise of what it will do — past performance does not guarantee future results.

What does HaterPicks cover?

HaterPicks compares prices across 14 US sportsbooks and prediction markets, including Kalshi and Polymarket, so you are looking at the whole market, not one book's view of it. The board covers the NFL, college football and the NBA, with MLB, the NHL, the WNBA and college basketball rolling out. Alongside the models, the free betting calculators let you check the math behind any bet yourself, and the public NBA research pages show recent-form context with no account needed.
