Catastrophe Modeling Software: A Market Overview for Risk Professionals
The catastrophe modeling software market, valued at approximately $1.82 billion in 2024, is a critical pillar of the global reinsurance and insurance industry. These platforms translate complex scientific data on natural hazards into probabilistic financial loss estimates, enabling underwriters to price risk and actuaries to manage portfolio aggregations.
The Dominant Vendors
Three companies have historically dominated the cat modeling space since the late 1980s:
- Moody's (formerly RMS)
- Acquired by Moody's for $2 billion in 2021, RMS pioneered cat modeling alongside AIR. Its cloud-native Intelligent Risk Platform hosts over 700 risk models, including 300+ from Nasdaq's Risk Modelling for Catastrophes. Moody's claims coverage of 70% of Lloyd's managing agents.
- Verisk (formerly AIR Worldwide)
- AIR Worldwide, which founded the cat modeling industry in 1987, was rebranded as Verisk Extreme Event Solutions in 2022. Its Touchstone platform models risks in over 90 countries. Verisk is developing Synergy Studio, a next-generation modeling platform.
- Aon (Impact Forecasting)
- Aon's ELEMENTS platform integrates over 135 probabilistic and scenario models covering 12 perils across nearly 90 territories. Uniquely positioned as a broker-developer, Aon offers both advisory and modeling capabilities.
Specialized and Emerging Vendors
Beyond the big three, several firms have carved out strong positions in specific perils or approaches:
| Vendor | Specialty | Differentiator |
|---|---|---|
| Karen Clark & Company | Multi-peril | Founded by the creator of the first commercial hurricane model; emphasizes model accuracy over complexity |
| KatRisk | Flood, TC Wind, Wildfire | High-resolution physics-based models; secured TA Associates investment in 2023 |
| JBA Risk Management | Global Flood | First probabilistic global flood model; 5m resolution in key markets |
| CoreLogic (EQECAT) | Multi-peril | Strong integration with property data analytics; acquired EQECAT for $20.5M |
The Open Source Movement
Oasis Loss Modelling Framework, founded in 2012, is a not-for-profit collectively owned by nearly 40 major insurers and reinsurers. With close to 100 associate members, it hosts 90+ models from 18+ suppliers on a fully open-source simulation engine. Nasdaq's Risk Modelling for Catastrophes platform is built on the Oasis framework, bridging the gap between open-source flexibility and enterprise-grade delivery.
What Drives Vendor Selection
For reinsurance actuaries evaluating these platforms, the key decision factors typically include:
- Peril and territory coverage — Does the vendor model the specific hazards and regions in your portfolio?
- Model transparency — Can you inspect assumptions, vulnerability functions, and hazard parameters?
- Integration — Does it connect to your existing exposure management and pricing workflows?
- Cloud vs. on-premise — Moody's and Verisk have moved aggressively to cloud-native; smaller vendors vary
- Regulatory acceptance — Certain jurisdictions require or prefer specific approved models
