Overtime Markets is an on-chain sports betting AMM running across Optimism, Arbitrum and Base. It grew out of the Thales Protocol on Ethereum (2021); Overtime's own sports-markets AMM launched in 2022, went through a V2 redesign in 2024, and completed a full rebrand around the $OVER token in April 2025. Rather than a peer-to-peer order book, Overtime uses a "pool-vs-peer" model: on-chain liquidity pools funded in USDC, ETH and wBTC continuously price and cover thousands of markets, with settlement happening fully on-chain and no withdrawal-approval queue to wait on.
Markets, parlays & onboarding
Overtime supports singles, multi-leg parlays, Same-Game Parlays and live in-play betting across 50+ leagues, including the NFL, NBA, MLB, Premier League, Champions League, UFC, tennis majors and esports. Onboarding is no-KYC either way: you can connect a self-custody wallet like MetaMask directly, or use a gasless social-login smart-account flow built on Particle Network and Biconomy account-abstraction infrastructure. Overtime describes the social-login option as non-custodial and permissionless, though the precise key-recovery mechanics of that third-party infrastructure aren't fully detailed in public documentation — something worth understanding before relying on it for meaningful funds. Pure wallet-connect remains available for anyone who prefers to hold their own keys directly. Overtime has reported roughly $200M in cumulative betting volume and 50,000+ users since launch, per its own April 2025 announcement; treat that as a self-reported figure rather than an independently audited number, since third-party analytics trackers show somewhat different totals.
Pros
- Genuinely on-chain settlement with instant, transparent payouts and no withdrawal-review step
- No-KYC onboarding with a frictionless social-login option, while still supporting pure self-custody for privacy-conscious users
- Strong same-game-parlay and live-market support backed by continuous on-chain liquidity
Cons
- On-chain liquidity is reported as relatively low relative to volume claims, which can mean bet-size caps on large or exotic wagers
- No dispute-resolution layer beyond the protocol's own governance and oracles
- The newer social-login wallet option adds third-party infrastructure dependencies worth understanding before depositing meaningfully
Platform & custody notes
Overtime settles on-chain via smart-contract liquidity pools, making it a non-custodial DeFi sportsbook by design. Its roots trace back to the Thales Protocol in 2021, with the current $OVER-token version live since April 2025 — a reasonable track record, though the underlying architecture has changed more than once along the way. Confirm current liquidity depth for your intended bet size, and availability in your jurisdiction, directly on overtimemarkets.xyz before committing funds.
Our verdict
Overtime is a strong pick if you want fast, on-chain settlement with real same-game-parlay and live-betting support, and you're comfortable evaluating a still-evolving protocol. Bettors who want the deepest possible liquidity for large single bets should compare current pool depth against a centralized alternative first.
