Overtime Markets was launched in 2022 by the Thales Core Council—a decentralized governance council elected by stakers of the Thales (later rebranded to OVER) protocol. Engineered as an on-chain, peer-to-contract sports betting protocol on Ethereum Layer-2 networks (Optimism and Arbitrum), Overtime eliminated traditional sportsbook frictions such as forced identity verification (KYC), account limits on winning traders, and centralized custody. Instead of matching order books or taking counterparty risk, Overtime utilizes an Automated Market Maker (AMM) architecture derived from binary option mechanics.
To establish fair market pricing without a centralized oddsmaker, Overtime routes real-time data feeds via Chainlink oracles that scrape benchmark odds from global market venues like Pinnacle. The protocol dynamically adjusts its odds using a dynamic "skew mechanism": when heavy capital flows onto one side of an outcome, the AMM automatically reduces payout odds for the backed side while boosting yields on the unbacked side. This incentivizes arbitrage traders to rebalance the protocol’s net exposure, protecting the vault liquidity pool from directional market risk.
Over time, Overtime expanded its sports derivative offerings from simple moneyline, spread, and total bets into complex single-game parlays (Parlay AMM) and multi-leg cross-sport parlays. By issuing positions as ERC-20 binary outcome tokens (settling at $1.00 for winning outcomes and $0.00 for losing outcomes), traders can sell or hedge their positions on secondary decentralized markets prior to match completion. Rebranded alongside its native governance ecosystem under the OVER token ticker, Overtime remains one of the largest non-custodial sports prediction protocols in decentralized finance.
- 2022 Overtime protocol launch on Optimism Thales DAO core council deploys Overtime Markets on Optimism L2, introducing the first permissionless sports betting AMM backed by Chainlink oracle feeds.
- 2023 Arbitrum multi-chain expansion Deploys core sports liquidity contracts onto Arbitrum, unlocking deeper L2 liquidity and lower transaction overhead for global bettors.
- 2024 On-chain Parlay AMM deployment Launches decentralized single-game and multi-event parlay engines, allowing users to combine multiple event outcome tokens into single smart contract positions.
- 2025 Purebet aggregator and router integration Integrates with non-custodial sports routers like Purebet to execute automated cross-venue arbitrage trades and execute optimal odds pricing.
- 2026 Governance rebranding to OVER token Thales protocol executes a unified brand consolidation, transitioning the native governance token ticker to OVER while introducing institutional single-sided liquidity vaults.
Overtime Markets was created and is governed by the Thales DAO and its community-elected Thales Core Council.
Overtime uses Chainlink oracles to fetch real-time benchmark odds from global market venues (such as Pinnacle). The AMM then applies a dynamic skew fee based on order imbalance to maintain balanced protocol risk.
Overtime operates natively on Ethereum Layer-2 scaling solutions, primarily Optimism and Arbitrum.
No, Overtime is a non-custodial, decentralized smart contract protocol. Users trade directly from self-custody EVM crypto wallets without registration, identity verification (KYC), or account restrictions.
OVER (formerly THALES) is the native protocol token used for decentralized DAO governance, staking rewards, liquidity pool backstopping, and receiving protocol fee distributions from sports trading volume.
