Private insurers are building AI tools to write more flood coverage as the National Flood Insurance Program's temporary funding approaches a September expiration. Severe floods in unexpected places-like Ruidoso, New Mexico, and Asheville, North Carolina-have exposed properties where mortgage lenders never required flood insurance, creating a coverage gap that AI-driven risk assessment can help close.
Pricing risk with back-office AI
Insurers, brokers, and reinsurers now use AI to price flood risks, measure appetite for those risks, and spot risk accumulations. John Dickson, president of Aon Edge, the flood insurance division of Aon, said the technology breaks down enormous datasets in ways that would overwhelm older modeling approaches.
"For flood, AI and advanced analytics help us ingest large amounts of hazard, exposure and loss data so we can give clients a more granular view of where their accumulations sit, how different scenarios might impact them, and what that means for their insurance strategies," Dickson said. Aon is investing $1 billion in technology and analytics over three years, though the company does not break out the AI portion.
Dickson sees a role for AI in back-office pricing and in front-office decision support. Flood maps often lag a decade behind changing weather patterns. AI can pull in current data to help a property owner understand their specific risk against today's events.
Shrinking product development cycles
Rajiv Matta, chief innovation officer at Lilypad Insurance, said the company applies AI to NFIP claims data for sharper flood risk analysis. The speed gains are measurable. "It used to take a year to get a product from an idea to finish. That cycle of product development has been squeezed to about three months now, because you can build a system very quickly to code by an issue of policy," Matta said.
Lilypad focuses on coastal home insurance, a segment where flood exposure is acute. The faster cycle lets the insurer design custom products that fill the protection gap Matta describes as the industry's responsibility to address.
Forecast validation and actionable decisions
Across the Atlantic, U.K.-based flood intelligence platform Previsico uses AI to validate forecasts against real weather events and turn probabilistic models into clear decisions. Mark Pinkerton, the company's chief technology officer, said the firm is deploying AI "to augment our proven hydrological models, expand into new flood types and turn our probabilistic forecasts into clear, actionable decisions for customers."
These applications are part of a broader push within insurance to apply AI not just for catastrophe modeling-which has used large language models for some time-but for communicating risk directly to clients. Aon recently began using AI to present risk information that helps clients choose coverage options.
Why this matters for insurance professionals
Flood represents a growing exposure as severe weather events hit areas outside traditional high-risk zones. When NFIP funding lapses, private carriers face both pressure and opportunity. AI tools that compress product development timelines and refine pricing give early adopters a way to expand their flood books without taking on blind risk. For underwriters and product managers, fluency with AI-driven data analysis pipelines is becoming a practical requirement, not a distant trend. The companies investing now in AI for insurance are building the infrastructure to spot coverage opportunities that outdated flood maps miss.
