​
The model

Every round is a self-contained pot. Stakes from the losing side are distributed to the winning side, pro-rata to each winning player’s stake. A small, published rake is taken from the pot at settlement. There is nothing else.

​
What you actually receive

If you are on the winning side of a round, you receive:
  1. Your original stake, returned in full.
  2. A pro-rata share of the losing pot, minus the rake.
Payouts are made in the same on-chain transaction that settles the round. There is no withdrawal queue, no minimum, no withdrawal fee, no “pending balance,” no “processing period.”

​
The rake

Prediction Arena takes a flat, published rake from each round’s losing pot. The exact percentage is listed on the market page for every market and is enforced by the smart contract — it cannot be raised silently, it cannot be raised for some players and not others, and it cannot be raised retroactively. There are no other fees:
  • No deposit fee. You move funds directly from your wallet into a round.
  • No withdrawal fee. Winnings go directly back to your wallet at settlement.
  • No spread. There is no order book and no market maker, so there is nothing to “spread.”
  • No priority lane. No player can pay extra for better odds, earlier information, or preferential settlement.
  • No VIP rebates. A whale and a first-time player pay the exact same rake on the exact same round.

​
What the rake funds

The rake covers:
  • Oracle fees paid to the price provider.
  • On-chain gas for opening rounds, settling rounds, and paying out winners.
  • Security: ongoing audits, the bug bounty program, and incident response.
  • Engineering and operations.
A standing portion of the rake is also routed to the community treasury, which funds bounties, integrations, and ecosystem grants. See Tokenomics for details.
