Decentralized onchain sports prediction protocol settling via Chainlink oracles across six EVM networks
Overtime is a decentralized, non-custodial sports prediction market that uses an automated market maker architecture and shared liquidity pools to quote odds on sporting events. Originating in 2021 out of the Thales market ecosystem, the protocol routes trades through smart contracts rather than a centralized bookmaker, settling outcomes using Chainlink data feeds.
The platform operates on a pool-vs-peer liquidity model across multiple EVM chains, including Arbitrum, Base, Optimism, Polygon, Ethereum, and BNB Chain. Instead of matching buyers against individual order books, liquidity providers deposit capital into unified pools, and an automated market maker dynamically calculates odds and payouts. Bets are executed directly from self-custody Web3 wallets without user accounts or identity verification procedures. The protocol uses the OVER token across its ecosystem, and users can trade single-match outcomes, live lines, and multi-leg parlays settled primarily in stablecoins such as USDC.
Overtime launched in 2021 as a core development from the Thales protocol. As of October 2026, protocol total value locked across its supported chains stood at approximately $1.32M. Related smart contracts covering AMM logic, liquidity pools, speed markets, and staking systems have been audited by firms including iosiro, Decurity, and CertiK.
Users face inherent smart contract exposure across the diverse chains hosting the protocol's liquidity pools. Because outcomes rely on automated sports results supplied by Chainlink oracles, incorrect data feed updates or delayed data feeds can interrupt match settlements. Liquidity pool participants bear counterparty risk when market outcomes swing heavily against pool reserves, and market depth can vary significantly between major sports leagues and niche fixtures.
Overtime offers non-custodial sports prediction markets with onchain settlement and automated market maker liquidity.
Overtime is a non-custodial sports prediction protocol that grew out of the Thales ecosystem and launched in 2021. Its main product is a sportsbook using AMM-style pricing and Pool-vs-Peer liquidity, so markets can price and trade without a central bookmaker. The protocol also has Speed Markets, a short-term options product powered by Chainlink Data Streams.
Overtime is deployed across Arbitrum, Base, Optimism, Polygon, Ethereum and BNB Chain, with Optimism and Base serving as its primary networks. The protocol uses Chainlink data feeds for resolution. That gives sports markets a defined oracle dependency, with the usual risks of delayed, disputed or manipulated data if an event result is handled incorrectly.
Liquidity is a mixed point. Overtime reported about $1.32 million in TVL on October 16, 2026, which indicates active capital in its contracts but does not establish deep liquidity for every event. Thin markets can produce wider execution differences and make larger positions harder to exit.
The strongest points are its non-custodial design, multi-chain deployment and use of automated pricing rather than a single centralized counterparty. Smart-contract custody reduces the need to deposit with an operator, though users still face contract and wallet risks. Audits are listed for several Thales-related contracts by iosiro, Decurity and CertiK, including AMM and liquidity-pool contracts. Those records support a history of external review, while the audited contract scope may not cover every current Overtime product.
Overtime suits traders who want sports markets settled through smart contracts and who can manage onchain transactions. A centralized sportsbook may fit better for users who need a stated fee schedule or a regulated venue. People trading event outcomes also face resolution disputes and oracle failure. The protocol has expanded beyond sports betting into casino games, which adds a separate category of contract and gambling risk.
