The bubble is the stage of a poker tournament just before the money; this explainer covers what it means, why it changes play and how to approach it.

In a poker tournament, the bubble is the stage just before players start winning money. If a tournament pays the top 100 finishers, the player who finishes 101st busts on the bubble, so close to the prizes yet leaving with nothing.
In a poker tournament, the bubble is the stage right before players begin winning money. Tournaments pay only a portion of the field — for instance the top 10 or 15 percent of entrants — so there is a precise moment when just one more elimination is needed for everyone left to be paid. That tense period, and the last unpaid finishing position, is what players mean by the bubble.
The player who busts in the position just short of the prizes is called the bubble boy or bubble girl . If a tournament pays the top 100 places, the player finishing 101st is on the bubble: agonisingly close to a payout, yet leaving with nothing. Because of that all-or-nothing edge, the bubble is one of the most psychologically charged phases in tournament poker.
The bubble matters because of how tournament payouts work. Once the bubble bursts — meaning one more player is eliminated — every remaining player is guaranteed at least the minimum cash. Reaching the money, often called “cashing” or being “in the money”, is a milestone that changes the emotional and strategic weight of every decision.
Crucially, chips in a tournament do not translate into cash in a straight line. Doubling your stack does not double your expected prize money, because payouts are fixed and shared among survivors. This is why the value of survival rises near the bubble: avoiding elimination can be worth more than a marginal chance to add chips. Understanding that idea is the key to bubble play.
Behaviour tends to split by stack size, because the risk of busting means very different things to different players. The table below sketches the common tendencies, though the right choice always depends on the exact situation.
The result is a period where many players fold more than usual, hoping someone else busts first. Skilled players notice this and adjust: if opponents are folding too readily, well-timed aggression can win uncontested pots. The bubble rewards awareness of how others are reacting to the pressure, not just the strength of your own cards.
ICM stands for the Independent Chip Model . It is a way of estimating the cash value of a player’s chip stack based on the remaining payouts, rather than treating chips as if they were money. ICM captures the fact that, near the bubble and at each pay jump, survival carries extra value because busting can cost you a guaranteed prize.
In practice, ICM helps explain why a call that would be routine early in a tournament can be a clear fold on the bubble. Risking your tournament life for a small edge is less attractive when elimination means winning nothing and survival almost locks up a payout. ICM is a model, not a crystal ball, but it gives a sound framework for the decisions that define bubble play.
There is no single script, but a few principles help. If you hold a big stack, you can use it to pressure medium stacks who are desperate to cash, picking up chips when they fold. If you are a medium stack, protecting your position often makes sense, avoiding needless confrontations that could bust you short. If you are short, you may need to find one good spot to commit rather than blinding away, balancing survival against the need to build a stack that can go deep.
Above all, remember that no approach guarantees a result on any given hand. Cards fall randomly and opponents make their own choices. The goal on the bubble is to make decisions that improve your expected value given the payouts — sometimes that means patience, sometimes calculated aggression. Reading the table and respecting how chip value shifts near the money is what separates disciplined bubble play from either reckless gambles or excessive fear.
Yes. The best-known is the money bubble , the point just before any prizes are paid, but tournaments have other bubbles too. A satellite bubble occurs in events that award seats into a larger tournament rather than cash, and here the stakes can be unusual: once you have enough chips to lock up a seat, adding more brings little benefit, so survival becomes especially important. A final-table bubble is the stage just before the last table forms, another point where players often tighten up to reach a prestigious milestone.
Each type shares the same underlying feature: a threshold that changes the value of survival relative to chips. Recognising which bubble you are approaching, and what is gained by crossing it, helps you judge how much caution or aggression the moment really deserves.
When the last unpaid player is eliminated, the bubble is said to have burst , and every remaining player is now guaranteed a payout. Play often loosens noticeably at this point, because the immediate fear of leaving with nothing is gone and attention shifts to the pay jumps ahead. Recognising this change — the sudden release of pressure once the money is reached — is part of reading a tournament well from the bubble onward.
The bubble is the stage of a tournament right before the money places begin. Once the bubble bursts, all remaining players are guaranteed a payout, so reaching it is a key milestone in every tournament.
The bubble boy, or bubble girl, is the player eliminated in the position just before the money. If the top 100 are paid, the person finishing 101st is the bubble, leaving with no prize despite lasting so long.
Because busting one place short of the money means winning nothing. Many players tighten up to secure a payout, especially short stacks, while larger stacks may attack that caution to gather chips.
ICM, the Independent Chip Model, estimates the cash value of your chips based on payouts. It shows why chips are not linear in value near the bubble, so survival can outweigh marginal chances to add chips.
Often yes. A big stack risks less by getting involved, because busting rivals cannot end its own tournament in most spots. That lets big stacks apply pressure to medium stacks trying to reach the money.
