A cluster of insurers and reinsurers is now selling wildfire coverage that pays out the moment a fire’s official perimeter crosses a boundary drawn around a specific property — sometimes within days, and without an adjuster ever inspecting the wreckage. The approach, called parametric insurance, has quietly moved from a niche tool for ski resorts and vineyards into products aimed at ordinary homeowners and neighborhood associations.

Key Points

• Liberty Mutual Re and satellite firm ICEYE launched what they call a “market-first” parametric wildfire cover on June 15, 2026, using radar satellites to sort individual buildings into “destroyed” or “undamaged” within hours of a fire.
• Insurtech Arbol launched a wildfire parametric product for California, Colorado, Arizona and other Western states in September 2025, with coverage up to $10 million triggered by satellite-confirmed fire proximity rather than a claims visit.
• Descartes Underwriting’s “Fire-in-a-Circle” policy pays a full, predetermined limit the instant a wildfire burns inside a client-drawn circle around a property.
• The Tahoe Donner homeowners association in Truckee, California, says its new policy is the first in the country to formally price in credit for a community’s own forest-thinning work.

The mechanics are what set these policies apart from a standard homeowners claim. Liberty and ICEYE’s version leans on synthetic aperture radar satellites that continuously scan wildfire-prone regions; after a blaze moves through, the imagery is layered against property footprint data and run through machine-learning models that flag each building as destroyed or untouched, according to Liberty Mutual Re’s own announcement. “By pushing the boundaries of technology, we are delivering a new generation of parametric wildfire coverage that is faster, more responsive, and fully data driven,” said Jean-Christophe Garaix, Liberty’s head of parametrics and agriculture, in the companies’ release. The product is initially available in the United States and Australia and is marketed to homeowner associations and residential communities alongside commercial and municipal accounts.

Arbol built its version to plug a gap left by insurers pulling out of fire-prone markets altogether. The company points to more than 150,000 California homeowners who have lost access to private coverage and landed on the state’s FAIR Plan, according to Arbol’s own announcement of the product. “There’s a deep need in the market for responsive, tech-forward wildfire coverage,” said Arbol chief executive Sid Jha in that release. The policy is backed by Lloyd’s syndicate Somers and can pay out up to $10 million, with the company promising payment within 10 business days of a confirmed trigger, according to Arbol’s wildfire product page.

Descartes Underwriting has been selling a variant of this idea since at least 2020, when a California resort covered by its “Fire-in-a-Circle” policy sat inside the geofenced zone during a wildfire event. Because the coverage is binary — the fire either crosses the line or it doesn’t — the company says the client would have qualified for a full payout of the policy limit “providing them with prompt liquidity,” even before a traditional damage estimate could be completed.

Not every parametric program is only about payout speed. Tahoe Donner, a Truckee-area homeowners association, worked with the Nature Conservancy, UC Berkeley and the risk firm Willis to build a policy that credits the association’s decade of mechanical thinning and prescribed burns across more than 1,500 acres, treating active forest management as a factor that can lower risk pricing rather than something insurers ignore. Taken together, the four programs mark the same shift: a fire’s line on a map is starting to carry as much weight in underwriting as the appraised value of the house sitting behind it.
