LONDON, UK, Jul. 6, 2026 — The iGaming landscape is splitting into two distinct paradigms: centralized crypto sportsbooks, which offer traditional fixed-odds betting, and decentralized prediction markets, which operate order-book style contracts on public blockchains. As trading volumes surge, both formats are competing for the same segment of crypto-native sports bettors.
Centralized platforms like Stake and Roobet operate as traditional bookmakers. They manage risk, dictate lines, and take the house edge (vig). This allows them to offer instant deposits, live betting options, and deep marketing promotions. However, users must trust the platform with custody of their funds and accept any betting limits placed on their accounts.
In contrast, decentralized prediction networks like Polymarket operate as peer-to-peer marketplaces. Because there is no house, prices are set by market consensus, leading to lower fees and superior odds. All contracts are resolved on-chain using smart contracts and public oracles. The trade-offs include higher friction for non-crypto users and lower liquidity on niche sporting events.
“The future points to hybrid integration,” says a DeFi protocol architect. “We expect centralized casinos to offer P2P event contracts as a sub-feature to capture retail users who want to bet on politics or macro trends. Both models will coexist, serving different betting styles and user preferences.”
