New DYSANOS model generates arbitrage-free option surfaces

Researchers have introduced DYSANOS, a novel generative market model designed to create smooth, arbitrage-free option surfaces for all strikes and expiries. This model can generate daily spot and option prices for years into the future, utilizing a baseline hidden state generative model in the form of an AR(1) model. The system's performance was evaluated using Option Metrics' IvyDB S&P Index data from 2020 to 2025, and its effectiveness was compared against a pure implied-vol PCA model. AI
