About Prevermarket
A prediction market built for live football.
Bet on what happens in the next 15 minutes of a match — not just on who wins. Every bet settles on-chain in USDC. No bookmakers, no margin built into the odds, no withholding your winnings.
Round-based betting, not fixed odds
Football is a 90-minute conversation. Prevermarket breaks it into six 15-minute rounds. For each round, the market asks one yes/no question: “Will a goal be scored between minute X and minute Y?”
You stake on YES or NO. When the round closes, everyone who bet the winning side splits the entire pool, proportional to how much they staked. The losing side funds the win.
Because the pool grows as more people bet, your potential payout shifts in real time — and you can watch it move on the round's history chart.
How payouts work
The contract holds every YES bet on one side of the pool and every NO bet on the other. When the round settles:
- Total pool = YES pool + NO pool
- Platform fee (currently 3%) is deducted
- The remaining pool is paid to the winners, weighted by their share of the winning side
So if you put $10 on YES, the YES pool has $40 total, and the NO pool had $60: when YES wins, you get back ($100 × 0.97) × (10/40) = $24.25. That's a 2.4× return on your stake.
Settled on-chain, every time
Prevermarket is non-custodial. Your bet sits in a Solidity escrow contract on Polygon Amoy testnet from the moment you place it until the round resolves. We don't hold your USDC. No one at Prevermarket can move it.
When a match ends, an off-chain resolver reads the final score and calls resolveRound() on the contract for every round. From that moment, anyone who won can call claim() and the contract pays them directly. No intermediary, no waiting period.
Why Polygon
Football is fast. A bet placed 30 seconds before a free kick should land before the ball is struck. Polygon confirms transactions in 2-3 seconds and costs cents per bet, which makes live, micro-stake betting actually feasible.
Ethereum mainnet would be slower (~12 seconds) and cost dollars per bet — fine for big prediction-market positions, untenable for in-play football.
What we charge
A single flat fee of 3% is deducted from every round's pool when it resolves. There's no spread, no margin baked into the odds, no withdrawal fee, no minimum stake.
The fee is split between operational costs and protocol development.
