Ownership Percentage

Ownership percentage is how many entries in a contest include a particular player. A player at 45% ownership is in nearly half the lineups.

Chalk is the DFS term for a highly owned player, usually one who is obviously good value on the slate.

Why it matters in tournaments

In a GPP, you are not trying to score well. You are trying to score better than thousands of other entries.

If a 50%-owned player has a huge game, you have gained nothing relative to half the field. You have kept pace. To move up you need players the field did not have.

This is the central insight of tournament play: the goal is not the best lineup, it is the best lineup that few others built.

Leverage

Leverage is the gap between a player’s ownership and their true probability of a strong game.

• Positive leverage: low ownership, genuine upside. This is what you want
• Negative leverage: high ownership relative to their prospects. Avoiding these is as valuable as finding the first kind

Deliberately fading a chalk player is a leverage play: if they disappoint, you gain ground on the large share of the field that rostered them.

Irrelevant in cash games

In a cash game you only need to beat the median, so being on the same players as everyone else is perfectly fine. Chalk is chalk because it is good value, and in cash games you should usually just play it.

Applying tournament ownership logic to cash games is a common and costly error.

Where the numbers come from

Projected ownership is estimated before lock by third-party services, using pricing, matchups and public sentiment. It is an estimate and often wrong, particularly for mid-priced players.

Actual ownership is published after contests settle and is the more reliable data for reviewing decisions.

The estimates are imperfect enough that treating them as precise is itself a mistake. They are most useful at the extremes, identifying who will be very heavily or very lightly owned, rather than for fine distinctions.
