When a heavy favourite wins and thousands of bettors collect, someone pays. At a traditional bookmaker, that someone is the company. At many Web3 sportsbooks, it is a liquidity pool funded by outside providers.
Pool-backed sportsbooks turn liquidity providers into the house. They earn from the margin built into odds and from losing bets, and they lose when results go against the book.
The mechanics of sportsbook pools, from liability across outcomes to correlated results on busy weekends, explain who really funds the payouts.

Every price includes a margin that funds the book over time. Bitzo's explainer on the margin in crypto sportsbook odds shows how to calculate it.
Liability Shapes the Risk
Sportsbook pools hold liability on each possible outcome. Heavy betting on one side leaves the pool exposed if that side wins.
Operators manage liability by moving odds and limiting stakes. Pool-backed books often move prices sooner and cap bets more tightly than large traditional bookmakers, since their capital is smaller.
Correlated Weekends
Popular favourites can win together on a single matchday. Accumulators stacked on those teams create correlated risk, where one set of results hits many tickets at once.
Why Odds Differ Between Pool Books
Pool size, liability and pricing models all affect the odds each book offers. Two sportsbooks can show different prices on the same match for those reasons, as an article on different odds across books explains.
Prediction markets add another twist, where trading volume and real liquidity often get confused. Bitzo's look at why volume and liquidity differ helps read those numbers.
Risks for Liquidity Providers
Providers earn the margin over time, yet bad weekends can cut their share sharply. Smart contract bugs, oracle errors and withdrawal lock-ups add further risk.
Bettors benefit from checking pool transparency too. Published balances and clear limits show whether a book can handle large payouts.
Dexsport's Shared Pool Model
Dexsport describes deposits as joining a liquidity pool that withdrawals later draw from, and its terms frame the platform as an interface for a protocol where games run between users' liquidity. Investors help fund the shared pool behind its prediction markets in exchange for part of the returns, and anyone can see that pool's balance.
Dexsport's sportsbook accepts bets at the line offered, so later odds changes leave placed bets untouched, and stake and win limits apply under its terms. The prediction markets follow their own limits, separate from sportsbook ones.
Anjouan licenses Dexapp LTD, the company behind Dexsport, and its terms allow ID checks whenever needed.
Conclusion
Web3 sportsbooks backed by liquidity pools make providers the house, earning from odds margins and losing bets while paying out on winning tickets. Liability on each outcome, not variance alone, drives the pool's risk.
Correlated results on busy weekends can hit pools hard, so operators move odds and cap stakes more tightly than large bookmakers. Pool size and pricing models explain why odds differ between books.
Dexsport makes its prediction market pool balance public and routes deposits into a shared liquidity pool. Check pool transparency and limits before large bets. Local betting rules come first, so confirm them, place bets only at legal age and keep in mind that KYC or AML checks may apply.
