The DeepBook App went live in alpha on Sui’s mainnet on September 24, combining spot markets, margin trading and ultra-short-term prediction markets in one interface. Its Predict feature initially lets traders take positions on Bitcoin’s price with expiry windows as short as one minute, using continuous strikes and a peer-to-pool model rather than fixed-strike options. DeepBook’s shared on-chain central limit order book has processed more than $20 billion in cumulative volume across over 15 applications. The app launched spot pairs including SUI/USDC, xBTC/USDC and DEEP/USDC, while the DEEP token supports fee management, incentives and governance. Sui’s average finality speed is approximately 390 milliseconds, and the app’s alpha waitlist exceeded 150,000 traders. Bitcoin is the initial Predict asset, with expansion to additional assets planned over time.
