A player prop is a bet about one player rather than about a game. The sportsbook posts a number for something that player might do — points, rebounds, receiving yards, strikeouts, total bases — and the bet settles from the box score at the end of the night. The final score does not settle it, and neither does who won.
Almost every player prop on a sportsbook is one of four shapes:
The first two are the ones this site scores, because both settle against a number and both have a record behind them that can be counted from box scores. A yes-or-no prop is the same question with the line hidden inside the wording: an anytime scorer prop is a bet on at least one, which is a threshold like any other.
Which stats are offered at all is the sportsbook’s decision and it changes from night to night. A market that was priced for a player last week may not be priced for him today, and that is not a data failure — the book simply did not post it.
A moneyline or a spread is a bet on the game and resolves with the result. A player prop resolves with one person’s workload, so the things that move it are the things that move that person: minutes, role, who else is available, the pace the two teams play at, the opponent’s shape against that stat. A prop can win comfortably in a heavy defeat, and the two questions are genuinely separate.
That is also why prop prices react so sharply to team news. A late scratch elsewhere in the lineup can change one player’s expected usage more than it changes the game’s own number, and prop markets are thinner, so they move further on less money.
And it is why the research on this site is per player and per market rather than per game. The record that matters for a prop is that player’s own log against that threshold — how often it has already happened, over how many games, and whether the venue or the opponent moved it.
Most sportsbooks void a player prop when the player takes no part in the game and return the stake. Inside a parlay a voided leg usually drops out and the remaining legs are repriced without it, the same way a push behaves. This is settlement rather than arithmetic, so it is the book’s rule and not a universal one — the exact wording differs between them and it is worth reading once for the book you use.
A player who takes the field and does nothing is a different case. Zero minutes into a game and zero production in a game he played are the same box score line and very different settlements, and the second is a loss rather than a refund.
The same four questions, whatever the sport and whatever the market:
Every one of those is a description of games already played, which is the limit of what a record can tell you and the reason this site prints the denominator beside every rate. The price is the other half of the comparison, and neither half means much on its own.
It means a bet on one player’s own statistics rather than on the outcome of the game. The sportsbook posts a number for something that player might do and you take the over or the under, or answer a yes-or-no version of the same question. It settles from the box score, so it can win in a loss and lose in a win.
Most sportsbooks void the bet and return the stake when the player takes no part in the game, and inside a parlay the voided leg usually drops out while the rest of the ticket stands. Settlement rules belong to the book rather than to any research tool, and they differ, so the wording is worth reading once for the book you use.
They settle the same way — the player’s own numbers are added together and compared with the line — but they are harder to read from history, because a combined line can be cleared by two different kinds of night. The measured record still applies at whatever threshold is being asked about; it is the explanation for the record that gets less obvious.
A player prop is one selection. A parlay is several selections combined into a single ticket that needs every one of them to land. A parlay can be built entirely out of player props, entirely out of game markets, or from a mix, and combining props from the same game has its own pricing consequences.
You can research them without one. Browsing the prop pages, the measured hit rates and the live prices needs no signup, and the bet itself is placed at a sportsbook rather than here — this site does not take bets or hold money.
