Prediction pool rules

Payouts are funded by the players in each pool. There are no fixed odds, no minimum profit, and no payout larger than the pool holds. These rules are shown before you enter and are frozen for a pool the moment it accepts its first entry.

Demo mode: pools are recorded and settled exactly as they would be, but no funds move and no balance is real.

How a payout is worked out

Write T for the total accepted stake in the pool, W for the total accepted stake on the winning outcome, and s for your own accepted stake on that outcome.

platform fee  = floor(T × feeBps ÷ 10,000)
distributable = T − platform fee
your payout   = floor(s × distributable ÷ W)

The default fee is 300 basis points, which is 3%. All arithmetic is done in the currency's smallest unit with whole numbers, so nothing is ever rounded in a way that creates or destroys value. If you have several entries on the winning outcome they are added together first, and you claim once. Whatever is left over after the proportional split, at most one unit per winner, goes to the treasury under the published dust policy.

The four settlement cases

A. A valid result with winners

The pool's frozen platform fee is taken from the total, and everything left is split in proportion to the stake on the winning outcome. Your payout includes your own stake. Losing entries receive nothing.

10 units staked, 3% fee: 0.30 to the platform, 9.70 shared. Eight equal winning stakes return 1.2125 each; two equal winning stakes return 4.85 each.

B. A valid result with no winning entries

The result is valid but nobody staked on the winning outcome. The whole pool transfers to the platform treasury and no additional fee is charged on top. This needs a verified valid result and zero stake on that outcome.

10 units staked, all on the losing side: 10 units to the treasury, no separate fee.

C. A market round that closes exactly where it locked

If the valid closing oracle price is exactly equal to the valid locked oracle price, the whole pool transfers to the treasury. The comparison uses the oracle's own canonical values, not the rounded number shown on a chart.

10 units staked, close equals lock: 10 units to the treasury.

D. A cancelled or invalid pool

Every participant's original stake is refunded in full and no platform fee is taken. Network transaction fees are never refunded. The reason is recorded, refunds cannot be issued twice, and an entry can never receive both a refund and a winning payout.

10 units staked and the pool is cancelled: 10 units refunded, zero platform fee.

What is never a house win

Missing, stale, invalid or disputed result data is never treated as a house win. A temporary provider outage pauses resolution. If valid settlement evidence cannot be obtained before a pool's published resolution deadline, the pool is voided and every stake is refunded. An empty pool closes with zero revenue.

What the numbers on a pool mean

Market rounds

Each round freezes its oracle feed, its lock and close times, the rule that picks an observation around each boundary, the maximum observation delay, the staleness and confidence thresholds, the settlement timeout and the tie policy. Settlement is simple: a close above the lock settles UP, a close below settles DOWN, an exact equality is a house win, and evidence that cannot be validated before the timeout voids the round. The exact observations used are stored and shown on the round.

Sports pools

Every sports market states the part of the match it settles on. Football match-winner pools settle on regulation time including stoppage time, and extra time and penalties do not count. A draw is a listed outcome and settles normally; it is not a cancellation. Totals use a half-point line so a push is impossible, and where an integer line is offered a push refunds every stake with no platform fee. Entry closes before kick-off and a locked pool never reopens, whatever happens to the score afterwards. A cancelled event refunds in full; a postponed event settles only if it is played inside the published rescheduling window and is otherwise refunded; an abandoned event refunds unless the result within the market's scope was already definitively established.

Claims and accounting

Winnings and refunds are claimed by you. Each entitlement is paid at most once, a refunded entry can never also be paid winnings, and total payouts can never exceed the pool. Platform fees, house transfers, payouts, refunds and unclaimed balances are tracked separately, and money owed to players is never reported as revenue.
