DeepBook Predict is now live on testnet: the third composable primitive in @SuiNetwork’s on-chain finance stack.

Spot (CLOB) + Margin (leverage) + Predict (options) = a powerful combination for building binary markets, calls/puts/spreads, leveraged products, and structured instruments, all sharing deep liquidity on one order book.
The Stack
• Spot: Sui’s native CLOB ($15M TVL, $15M+ daily volume, 20+ apps)
• Margin: Leverage + borrow/lend (strong early traction)
• Predict: Native options primitive with Block Scholes oracle for institutional-grade pricing + sub-second settlement
— What builders can ship:
• Polymarket-style binary markets
• Full options (calls, puts, spreads)
• Leveraged tap-to-bet apps (Predict + Margin)
• 3x leveraged BTC ETFs / structured products
• Multi-asset portfolios using all three primitives
— Key advantages:
• Positions are fully composable (leverage them, use as collateral, build spreads in one tx)
• Internal market maker for instant liquidity on new markets
• ~400 ms settlement on Sui → gaming-like UX
On-chain prediction markets and options have been underdeveloped compared to perps. This directly targets that gap with real infrastructure instead of isolated tokens.
Testnet is open now. Mainnet + first-party trading app later this year.
Sui’s financial primitives are getting seriously competitive.
What do you think; will composable on-chain options finally take off?
