The DeepBook App launched in alpha on the Sui mainnet on September 24, 2026. It provides a unified interface for spot trading, margin positions, and prediction markets. The platform utilizes a shared on-chain central limit order book, which has already processed over $20 billion in cumulative volume across more than 15 applications.
The core feature, Predict, allows users to speculate on Bitcoin price movements with expiry times as short as 60 seconds. Unlike event-based markets, this tool is price-based and uses continuous strikes with a peer-to-pool model. Pricing is managed through advanced oracles, and the system leverages the Sui network's average finality speed of approximately 390 milliseconds.
The platform supports spot trading pairs such as SUI/USDC, xBTC/USDC, and DEEP/USDC. The DEEP token is used for fee management, governance, and user incentives. The project previously tested the feature on the Sui testnet in May 2026 in partnership with Block Scholes, attracting a waitlist of over 150,000 traders for the alpha launch.
DeepBook differentiates itself by integrating multiple trading types into one interface, reducing the need for users to switch between different protocols. While Bitcoin is the only asset currently available for the Predict feature, the team has announced intentions to add more assets in the future.
