what's MarkIt?

MarkIt is an onchain prediction market and sportsbook platform built on the Base blockchain. It reimagines traditional sportsbooks by enabling users to "be the book" through depositing USDC into shared liquidity pools that back all available markets. Pricing follows transparent, verifiable onchain curves with a fixed formula for the house edge, which is community-owned and shared among participants, eliminating arbitrary limits, shading, or exclusions common in centralized platforms. Bets settle automatically in USDC with full onchain auditability. Users build ongoing stake via participation rather than acting as mere customers. Integrated with web3 tools like Privy for seamless wallet-based access, it's designed for non-US users and focuses on sports events with potential expansion to broader predictions.[[1]](https://x.com/i/status/2034689416539906480)[[4]](https://x.com/i/status/2034689409527029779)

MarkIt is a permissionless Base sportsbook; users deposit USDC to underwrite trades and earn spread.
