Jupiter Poker is a marketplace where you can buy a share of a real poker player’s tournament entry. Before using the product, it helps to understand a few poker fundamentals and the specific vocabulary used across the interface. This page is a reference: read it once if you’re new to live poker, or come back to it whenever a term is unclear. If you already know how live poker tournaments work, you can skip to How It Works.

​
What Action Selling Is

In live poker, a tournament has a fixed cost to enter, called the buy-in. For high-stakes events, this amount can be very large ($25,000, $100,000, or more). Many professional players don’t want to put up the full buy-in themselves, so they sell action: they let other people pay part of their buy-in in exchange for a proportional share of any prize they win. This practice exists in live poker as a private agreement between a player and their backers. It is informal, off-chain, and based on trust. Jupiter Poker brings this practice onchain: every share is represented as a position recorded on Solana, payouts are settled programmatically, and no one needs to trust an intermediary to hold or distribute funds. The role you play on Jupiter Poker is the backer role. You are not the one playing the tournament. You are the one funding a share of a player’s entry, and you receive a proportional share of their winnings if they finish in a paying position.

Poker Tournament Concepts

These are general poker terms used across the Jupiter Poker interface and documentation. They are not specific to Jupiter.
The fixed amount of money a player must pay to enter a tournament. For example, a “$100,000 No-Limit Hold’em Main Event” has a buy-in of $100,000 per player. The buy-in is paid once, to the casino or tournament operator, before the tournament starts.
The total amount of money distributed to the top finishers of a tournament. It is built from the buy-ins of all players who entered (minus the casino’s fee, where applicable). A bigger field means a bigger prize pool.
The total number of players entered in a tournament. The size of the field directly affects the prize pool and the number of paying positions.
The breakdown of how the prize pool is distributed among finishing positions. The winner gets the largest share, second place gets less, and so on, down to the lowest paying position. Each tournament publishes its full payout structure before play begins.
. A player is “in the money” when they finish in a position that receives a payout. Players who finish outside the paying positions receive nothing.
. The lowest-paying position in a tournament. For example, in a tournament that pays 11 positions, MIN ITM refers to the 11th-place finisher. This is the smallest payout a player can win while still being in the money.
A verb meaning to finish in the money. “The player cashed” means they finished in a paying position and received a payout. The size of the cash depends on where they finished.
A verb meaning to be eliminated from the tournament. A player “busts” when they lose all their chips and are knocked out. If the player busts before reaching the money, they receive no payout, and neither do their backers.
The position immediately before the money. The “bubble” is the last player eliminated before payouts begin. Busting on the bubble means finishing one place short of cashing.
A prize awarded for eliminating a specific player. In a “bounty” tournament, part of each player’s buy-in becomes a bounty on their head. Whoever eliminates them collects it. Bounty payouts are separate from the standard prize pool.

Jupiter Poker Concepts

These terms are specific to how Jupiter Poker is structured. You’ll see them in the interface, in this documentation, and in any communication about the product.
A poker festival: a set of tournaments organised by the same operator in the same location over a defined period. Triton Super High Roller Series Montenegro 2026 is one series.
A single tournament inside a series. Each event has its own buy-in, format (No-Limit Hold’em, Pot-Limit Omaha, etc.), and prize pool. The “$100,000 Pot-Limit Omaha Main Event” is one event inside the Triton Montenegro 2026 series.
One player’s offer to sell action for one specific event. If two players are selling action for the same event, that’s two separate listings. A listing displays the player, the event, the target raise, the fill progress, and the time remaining.
The poker professional whose entry you can buy a share of. Every player on Jupiter Poker is verified by Triton and Jupiter, with their identity publicly displayed alongside their listing.
You, when you buy a share of a player’s listing. The backer funds part of the player’s tournament entry and receives a proportional share of any payout the player wins.
The act of buying a share of a player’s listing on Jupiter Poker. Throughout this documentation, “staking” refers exclusively to this action. It has no relation to Solana staking or to staking JUP for governance.
The total USDC amount the player wants to raise from backers for a given listing. This is set by the player and is typically a fraction of the tournament buy-in, not the full buy-in.
How much of the target raise has been bought by backers, expressed as a percentage. A listing at 64% fill has raised 64% of its target. A listing at 100% fill is fully raised.
The amount of USDC you commit when staking a listing. The buy amount includes Entry Fees: a small portion goes to fees, the remainder funds your position.
Your share of a player’s action, recorded onchain after you complete a buy. The position is expressed as a percentage of the player’s tournament buy-in and determines your share of any payout.
The percentage of the player’s tournament entry that your position represents. If you hold 1% of action on a player who wins $100,000, you receive $1,000 before any settlement-side adjustments.
The fee Jupiter charges on each buy. The fee is shown explicitly in the buy modal before you confirm.
A minimum target raise level a listing must reach by its deadline. If the listing fails to reach this level, the listing is cancelled and every backer is refunded automatically.
A label shown on each listing card describing where it stands in its lifecycle. Examples include RAISING (open for buys) and RAISED (target reached).
The process by which the tournament result is recorded onchain and payouts become claimable by backers. Settlement happens after the event ends in real life.
The action a backer takes to receive their share of a payout after settlement. A claim requires one wallet signature and credits USDC to the backer’s account.
USDC returned to the backer when a listing is cancelled (auto-cancel threshold missed, event cancelled, or other refund-eligible conditions). Refunds are visible in the dashboard alongside claims and stakes.

​
How a Listing Is Priced

Every listing displays the player’s tournament buy-in and the listing’s target raise side by side. These are two different numbers. The tournament buy-in is what the player owes to the casino to enter the event. For example, $100,000 for the No-Limit Hold’em Main Event. The target raise is what the player wants to raise from backers through Jupiter Poker. It is usually a fraction of the buy-in: the player covers the rest themselves. When you stake a listing, your buy amount in USDC translates into a % of action: the share of the player’s tournament entry that your position represents. The payout you can claim, if the player cashes, is proportional to that percentage.
For the exact math (buy amount → position → % of action → payout), see How It Works.

​
Listing Lifecycle in One Line

A listing moves through stages: it opens for buys, fills up (or doesn’t), the event is played, and the result is recorded onchain. Backers either claim a payout, hold a losing position, or receive a refund if the listing was cancelled. The full lifecycle, including each status and the exact rules for refunds and payouts, is covered on the How It Works page.
