Decentralized order book exchange Lighter appears poised to enter the prediction market sector following a codebase commit titled "Binary options support," indicating ZK Circuits now support binary outcome markets. The implementation features settlement caps with share prices trading between zero and the cap, resolving at either extreme. Contracts are fully collateralized by USDC, eliminating leverage and liquidation risks. Analysis suggests Lighter may adopt a "market operator" model similar to HIP-3 deployment standards. This framework would allow whitelisted operators to create, manage, and settle markets, shifting from open permissionless creation to a curated approach for binary result markets on the platform.
